Abstract:

Objectives: Clearance of the pharynx by deglutition is important in protecting the airway. The pattern of deglutition during sleep was investigated in children. Methods: Ten normal human children (8.6 ± 2.9 years) were examined via time-matched recordings of polysomnography and of surface electromyography (EMG) of the thyrohyoid and suprahyoid muscles. Results: During sleep, deglutition was episodic, and it was absent for long periods. The mean number of swallows per hour (±SD) during the total sleep time was 2.8 ± 1.7 per hour. The mean period of the longest absence of deglutition was 59.7 ± 20.3 minutes. Most deglutition occurred in association with spontaneous electroencephalographic arousal in rapid eye movement (REM) and non-REM sleep. Deglutition was related to sleep stage. The mean number of swallows per hour was 27.4 ± 27.4 during stage 1 sleep, 3.1 ± 3.5 during stage 2 sleep, 2.8 ± 3.3 during stage 3 sleep, and 0.9 ± 0.8 during stage 4 sleep. The deeper the sleep stage became, the lower the mean deglutition frequency became. The mean number of swallows per hour was 2.2 ± 2.1 during REM sleep. The EMG amplitude dropped to the lowest level of recording during REM sleep. Conclusions: Deglutition, a vital function, is infrequent during sleep in children.

Abstract:

The purpose of the present study was to investigate whether or not sensory input from the tongue affects deglutitive tongue movement. Subjects were seven healthy volunteers with anesthetic applied to the surface of the tongue (surface group) and seven healthy volunteers with the lingual nerve blocked by anesthetic (blocked group). We established six stages in deglutition and analyzed deglutitive tongue movement and the time between the respective stages by cineradiography before and after anesthesia. After anesthesia in both surface and blocked groups, deglutitive tongue movement slowed and bolus movement was delayed. The deglutitive tongue tip retreated in the blocked group. These results suggest that delay of tongue movement by anesthesia causes weak bolus propulsion and that deglutitive tongue tip position is affected by sensory deprivation of the tongue or the region innervated by the inferior alveolar nerve.

Abstract:

Background: Deglutition requires great muscular and nervous coordination. Dysphagia is defined as swallowing impairment in any of its phases: preparatory, oral, pharyngeal and esophageal. Its causes are diverse, and diagnosis is imperative to avoid detriment to the quality of life. Objective: To identify the risk factors for deglutition disorders in the institutionalized elderly population. Material and methods: Clinical and descriptive trial. We included patients above 60 years of age assessed at the Otolaryngology Department at the Hospital Español from October to December 2016. Deglutition dynamic tests were performed, and three questionnaires commonly used as geriatric scales were applied to each patient. Statistical analysis was performed using Pearson coefficient to determine the correlation and strength between variables. Results: Fifty patients were included. Data of food aspiration to the airway was found (n = 31, 62%). Systemic hypertension (61%) and neurological deficiencies (51%) showed greater prevalence when deglutition disorders were present. Folstein’s brief mini-mental is a sensitive and specific scale when deglutition disorders are suspected (S = 100%, E = 100%, LR + 100%, r = 1). Conclusions: Deglutition disorders are multifactorial. Folstein’s brief mini-mental and other geriatric questionnaires are useful tools to screen deglutition disorders.

Abstract:

Deglutition syncope is a relatively rare cause of syncope that belongs to the category of neurally mediated reflex syncopal syndromes. The phenomenon is related to vagal reflex in context to deglutition causing atrioventricular block and acute reduction in cardiac output leading to dizziness or syncope. We present case series of two cases of deglutition syncope, of which first was managed medically and second with pacemaker implantation.

Abstract:

In this investigation, particular attention was paid to elucidate the laryngeal reflex mechanism of protective closure and the sensory function of the larynx during deglutition. For this purpose, three different experimental procedures were adopted: (1) subglottal pressure of felines was measured during deglutition using a pressure transducer; (2) subglottal pressure of human beings was measured during deglutition using a pressure transducer; and (3) afferent discharges from superior and recurrent laryngeal nerves of felines were recorded. The following conclusions appear justified. (1) Feline and human subglottal pressure during deglutition showed the following pattern. The pressure rises with onset of deglutition, temporarily drops during laryngeal elevation, rises again during the downward movement of the larynx, and drops again at the end of the glutltion. This pattern was not affected by the resection of the unilateral recurrent laryngeal nerve. (2) The superior laryngeal nerve is involved in the sensory function of the pharynx, larynx, and trachea. At least two types of afferent discharges from superficial and infernal sensory nerves are suspected. Afferent discharges from the recurrent laryngeal nerves in the larynx and trachea are not as distinct as those of the superior laryngeal nerve, and this seems to correspond with various changes in the thorax. During deglutition, afferent discharges were recorded from superior to recurrent laryngeal nerves.

Abstract:

ABSTRACT Objective: To investigate any change in deglutitive tongue movement following the correction of malocclusion by orthognathic surgery. Materials and Methods: The subjects were nine patients with mandibular protrusion. A control group consisted of 10 individuals with a similar age range and normal occlusion. Swallowing events before and after mandibular setback via sagittal split ramus osteotomy were recorded by cineradiography, and the tongue movement was analyzed. Time and linear measurements were compared before and after surgical treatment by the Wilcoxon signed rank test; control and test subjects were compared with the Mann-Whitney U-test. Results: Tongue-palate contact and the tongue-tip position changed after orthognathic surgery and became similar to those of the controls. Movements of the anterior and middorsal regions of the tongue did not change after orthognathic surgery and remained different from those of the controls. Conclusion: Our findings suggest that tongue-palate contact and tongue-tip position during deglutition adapted to the corrected oral and maxillofacial morphology, but the anterior and middorsal regions of the tongue during deglutition may have been affected by pharyngeal constrictors rather than by the oral and maxillofacial morphology.

Abstract:

Purpose Diagnostic precision and prolonged testing before, during, and after deglutition is lacking across the age spectrum. Conventional clinical evaluation and radiologic methods are widely used but are reliant on human perception, carrying the risk of subjectivity. High-resolution manometry (HRM) is an emerging clinical and research tool and has the capability to objectively measure the dynamics, kinetics, regulatory, and correlation aspects of deglutition. Method We review the basics of manometry and the methods, metrics, and applications of this technology across the age spectrum. The goal is to aid in the translation of HRM from research tool to clinical use by the speech-language pathologist in the development of better global plans to understand normal and abnormal deglutition. Results HRM is an easily adaptable precise diagnostic tool that can be used to examine deglutition phases and abnormalities across the age spectrum from neonates to nonagenarians and can be a valuable adjunct to specialty evaluation of persistent deglutition disorders. Conclusion New opportunities will emerge upon further research for larger-scale translation once normative data and recognition of biomarkers of abnormality are ascertained.

Abstract:

AbstractAspiration into the lower respiratory tract can be detrimental to life. Ten patients, suffering from neurological dysphagia with aspiration, were studied. Neurological disorders can cause inadequate glottic closure resulting in aspiration. It has not been well recognized however, that even patients who have full glottic closure are still capable of aspirating in the pre- and post-deglutition stages of swallowing. The combined techniques of videofibrolaryngoscopy and videofluoroscopy are found to be the best methods for demonstrating these abnoralities. Development of new techniques, in the prevention of aspiration, should also take into account silent, pre- and post-deglutitional aspiration.

Abstract:

Objective: evaluate the possible correlation with the radiographic position of the hyoid bone and mandibular angle in lateral radiographs of children with atypical deglutition. Study design: This was an observational study using cephalometric analysis of lateral teleradiographs for the distances of H-MP (hyoid to mandibular plane). Spearman’s correlation analysis was performed with MA (mandibular angle) in two groups: the experimental group with atypical deglutition and the control group normal deglutition. Both groups included subjects in mixed dentition stage. Results: there was a significant moderate negative correlation between MA (mandibular angle) and hyoid bone (H-MP) in the normal group (R = −0.406, p = 0.021). However, there was no significant correlation between the MA and H-MP (R = 0.029, p = 0.83) in the group with atypical deglutition. Conclusion: there is a moderate negative correlation between the position of the hyoid bone and mandibular angle in the group of normal swallowing and there is no correlation between variables H-MP and MA in the group of atypical swallowing.

Abstract:

Patients with velopharyngeal insufficiency (VPI) without cleft palate, who appear for the first time in adulthood for treatment, will probably reveal a high percentage of undiagnosed myotonic dystrophy (MD). Videoradiography of deglutition and speech reveals the diagnosis. Eleven adult noncleft palate patients with VPI were studied with videoradiography of the pharynx and esophagus. Three exhibited functional radiographic manifestations of MD during deglutition and speech. The diagnosis confirmed by neurologic examination was not known or suspected prior to videoradiography. An additional patient with VPI and suspected MD displayed the same constellation of radiographic findings. Follow-up examinations confirmed the diagnosis of MD. Three of the four patients had had symptoms of VPI since childhood, but none had complaints of deglutition problems except for accidental nasal regurgitations.

Abstract:

Summary Introduction: Parkinson disease is one of the pathologies mostly affecting deglutition. Objective: To analyze the efficiency of both deglutition and cough reflex in cases of laryngeal penetration or tracheal aspiration with food, in different severity stages of Parkinson disease. Study's way: contemporaneous cohort with transverse incision. Method: The sample had 38 patients in the study group and 38 individuals in the control group submitted to a neurologic evaluation and an otorhinolaryngological evaluation by transnasal fiberoptic laryngoscopy. Results: The cough reflex was manifested in 100% of patients without food offering. Alimentary stasis in piriform recesses and epiglottic vallecula in solid, pasty and liquid consistency was significant (p= 0.0000). The laryngeal penetration in liquid consistency was significant (p= 0.0036). Tracheal aspiration occurred in 06 patients of the study group in liquid consistency and it was absent in control group. Conclusion: The efficiency of deglutition in the study group prevailed in the solid consistency, followed by pasty and liquid consistencies. In the control group, deglutition was effective in all individuals. Cough reflex was efficient in most patients of the study group and prevalently inefficient in the subgroup 2.

Abstract:

AbstractDeglutition disorder is a clinical symptom that has been associated with inhalation and cutaneous thermal burn injuries. Deglutition disorder is present in approximately 11% of patients with burn injury and is known to persist for weeks to months postinjury. Here, we report a case of deglutition disorder associated with cricopharyngeal dysfunction in a patient with thermal burn injury. Two patients presented with deglutition disorder lasting for several weeks after thermal injury. Clinically, it manifested as combined liquid and solid food dysphagia. The findings of videofluoroscopic swallow study (VFSS) were poor relaxation of the pharyngoesophageal sphincter (PES), decreased elevation of the laryngohyoid, and inadequate pharyngeal contraction. The PES was dilated with a 20-mm expansion balloon catheter multiple times. The symptoms of deglutition disorder were relieved immediately after the procedure. Balloon catheter dilatation was performed four times at 1- to 2-week intervals. Follow-up VFSS showed that poor relaxation of the PES was improved. The VFSS showed no recurrence at the 3-month follow-up. We found that balloon catheter dilatation for treatment of a patient with cricopharyngeal dysfunction after thermal burn injury was effective, ease of use, and safe.

Abstract:

Introduction Supracricoid laryngectomy still has selected indications; there are few studies in the literature, and the case series are limited, a fact that stimulates the development of new studies to further elucidate the structural and functional aspects of the procedure. Objective To assess voice and deglutition parameters according to the number of preserved arytenoids. Methods Eleven patients who underwent subtotal laryngectomy with cricohyoidoepiglottopexy were evaluated by laryngeal nasofibroscopy, videofluoroscopy, and auditory-perceptual, acoustic, and voice pleasantness analyses, after resuming oral feeding. Results Functional abnormalities were detected in two out of the three patients who underwent arytenoidectomy, and in six patients from the remainder of the sample. Almost half of the sample presented silent laryngeal penetration and/or vallecular/hypopharyngeal stasis on the videofluoroscopy. The mean voice analysis scores indicated moderate vocal deviation, roughness and breathiness; severe strain and loudness deviation; shorter maximum phonation time; the presence of noise; and high third and fourth formant values. The voices were rated as unpleasant. There was no difference in the number and functionality of the remaining arytenoids as prognostic factors for deglutition; however, in the qualitative analysis, favorable voice and deglutition outcomes were more common among patients who did not undergo arytenoidectomy and had normal functional conditions. Conclusion The number and functionality of the preserved arytenoids were not found to be prognostic factors for favorable deglutition efficiency outcomes. However, the qualitative analysis showed that the preservation of both arytenoids and the absence of functional abnormalities were associated with more satisfactory voice and deglutition patterns.

Abstract:

In order to determine factors that may contribute to deglutition problems following supraglottic horizontal laryngectomy or its modified techniques, clinical records of 38 patients were studied. Contribution of the following factors was investigated: Age; sex; tumor classification; radical neck dissection; extent of and symmetry in removal of the aryepiglottic folds, arytenoid cartilages, and false folds; removal of the base of the tongue, hyoid bone, and a part of the vocal folds; extent of removal of the epiglottis and thyroid cartilage; cricopharyngeal myotomy; and some complications and concomitant diseases. The results suggest that removal of the arytenoid cartilage and asymmetrical removal of the false folds contribute to deglutition problems. We conclude that the standard supraglottic horizontal laryngectomy associated with surgical approximation of the larynx to the base of the tongue and cricopharyngeal myotomy does not usually cause serious deglutition problems. When the arytenoid cartilage is removed, reconstruction of the structure is required for the prevention of severe aspiration.

Abstract:

Purpose: To evaluate the functional disorders of the oral and pharyngeal phases of deglutition after repair of esophageal atresia in children. Material and Methods: 19 children (10 girls, 9 boys, mean age 22 months) underwent videofluoroscopy of deglutition after repair of esophageal atresia. The videofluoroscopic studies were assessed according to functional and morphological changes in the oral, pharyngeal and esophageal phases. The persistence of radiologic findings on videofluoroscopy was determined. Results: The oral phase was normal in all patients. The main functional disorder of the pharyngeal phase was aspiration in 7 (37%) children. A completely normal deglutition in the pharyngeal and esophageal phases was not seen in any patient. Conclusion: Videofluoroscopy after repair of esophageal atresia is helpful in differentiation of functional and morphological disorders that can lead to prandial aspiration and have an influence on the decision about continued therapy.

Abstract:

Oropharyngeal dysphagia is a major complaint among older people. Dysphagia may cause two types of complications in these patients: (a) a decrease in the efficacy of deglutition leading to malnutrition and dehydration, (b) a decrease in deglutition safety, leading to tracheobronchial aspiration which results in aspiration pneumonia and can lead to death. Clinical screening methods should be used to identify older people with oropharyngeal dysphagia and to identify those patients who are at risk of aspiration. Videofluoroscopy (VFS) is the gold standard to study the oral and pharyngeal mechanisms of dysphagia in older patients. Up to 30% of older patients with dysphagia present aspiration—half of them without cough, and 45%, oropharyngeal residue; and 55% older patients with dysphagia are at risk of malnutrition. Treatment with dietetic changes in bolus volume and viscosity, as well as rehabilitation procedures can improve deglutition and prevent nutritional and respiratory complications in older patients. Diagnosis and management of oropharyngeal dysphagia need a multidisciplinary approach.

Abstract:

The role of solitarial gamma-aminobutyric acid (GABA)-ergic mechanisms in deglutition was investigated in urethane-anesthetized rats. When applied to the dorsal extraventricular surface of the nucleus tractus solitarii (NTS), muscimol reversibly inhibited 1) buccopharyngeal swallows evoked by either electrical or chemical stimulation of the NTS and 2) esophageal peristalsis evoked by muscarinic agonists. Bicuculline (5-1,000 pmol) applied to the NTS surface evoked rhythmic swallowing, which was reversibly blocked by DL-2-amino-7-phosphonoheptanoic acid (5-500 pmol). Methscopolamine (5-100 pmol) applied at the same site abolished the esophageal component of the response. Intrasolitarial application of bicuculline at s-glutamate-responsive loci in the intermediate and central subnuclei gave rise to buccopharyngeal and esophageal responses, respectively, and to a concomitant facilitation of glutamate-evoked responses. In subliminal doses ejected at esophageal loci, bicuculline induced deglutitive esophageal peristalsis during elicitation of buccopharyngeal swallowing by chemical (kainate or norepinephrine) or electrical stimulation of the NTS. We conclude that solitarial GABA neurons exert a tonic inhibition of the medullary deglutitive pattern generator and control buccopharyngeal-esophageal coupling.

Abstract:

Atypical deglutition (tongue thrust swallowing) has been thought by some to be an etiological factor related to dental malocclusion, especially changes related to excessive increase in vertical facial growth. The purpose of this study was to investigate this possible relationship between atypical deglutition and vertical facial growth by documenting the lower, middle and upper facial areas of children with atypical deglutition. 55 lateral cephalometric radiographs were analyzed and measured in each of two groups of subjects according to standardized facial plane angles between the (I) palatal plane and mandibular plane, (II) palatal plane and occlusal plane, (III) mandibular plane and occlusal plane, (IV) skull base and Frankfurt plane, and (V) mandibular angle. The experimental group was comprised of 55 subjects with atypical deglutition, while 55 subjects with normal swallowing were used as a control group. The linear/angular measurements were subjected to Mann-Whitney statistical test with a significance level of 5%. Results: The average angle of the variables I, II, III and IV are, respectively: 29, 14, 14 and 9 degrees in both groups. There were no significant differences in the variables studied in the normal and atypical swallowing groups. However, for variable V there were 3 degrees of difference between the groups, which was statistically significant. The results of this study suggest that the problem of atypical swallowing may be of functional origin and not associated with anatomical changes seen in vertical growth patterns.

Abstract:

Objective: Surgical procedures on the larynx lead to some swallowing disorders of that may occur at any time during the postoperative period and can be present in all phases of swallowing. The aim of the study was to explore the prevalence of dysphagia after laryngectomy, the correlation and difference in dysphagia symptoms depending on the extent of the surgery. Methods: The study included 40 laryngectomized subjects of both sexes, median age 63.50 years. Data were collected by a survey of respondents and questionnaire structured from three sets of closed-ended questions. The data were statistically processed in the statistical program SPSS (version 16.0, SPSS Inc., Chicago, IL, USA). Results: The incidence of dysphagia is more often after partial laryngectomy with statistically significant differences in certain symptoms. A positive and statistically significant correlation was found between swallowing disorders and the consequences of oncological treatments. A negative and statistically significant correlation was found between swallowing disorders and the type of complications. Conclusion: The results show that patients who had surgery have varying degrees of swallowing disorders. The ability to identify symptoms of dysphagia becomes increasingly important when developing appropriate interventions for this subgroup of laryngeal cancer patients.

Abstract:

This paper describes a primary voice restoration technique designed to eliminate the problem of aspiration commonly encountered in rehabilitation procedures following laryngectomy. This technique, utilized in 16 patients, consists of a unique combination of tracheal flap for voice production and bilateral esophageal constrictor muscle flaps to prevent aspiration. Fourteen patients developed satisfactory tracheoesophageal speech; of them 12 had normal deglutition without problems of aspiration. On radiographic examination, the bilateral esophageal muscle flaps, in combination with the dilatation and elevation of the cervical esophagus, provide a sphincter mechanism that prevents tracheal reflux during deglutition.

Abstract:

Glottic closing pressure and time were quantitatively analyzed during deglutition and in reflex glottic closure elicited by superior laryngeal nerve stimulation by means of a catheter pressure transducer in the cat. Duration and peak pressure of glottic closure during deglutition were 322.6 ± 32.2 msec (mean ± SE) and 57.5 ± 6.0 mmHg, respectively, whereas peak pressure of the reflex glottic closure was 21.7 ± 6.1 mmHg in control animals. When the recurrent laryngeal nerve was denervated unilaterally, decrease in peak glottic closing pressure on swallowing was only about 36%, whereas the peak pressure of reflex glottic closure was markedly diminished to 4.5 ± 4.6%. When bilateral recurrent laryngeal nerves denervated, decrease in peak pressure during deglutition showed no greater significance than It did after unilateral denervation. Inferior constrictors myotomy in addition to bilateral recurrent laryngeal nerve denervation reduced peak pressure to nearly zero. These results indicate that on swallowing, the inferior constrictors cooperate with the intrinsic laryngeal adductors, thus playing a very important role in reinforcing glottic closure, a function that is unlikely during reflex glottic closure.

Abstract:

CONTEXT: In Machado-Joseph disease, poor posture, dystonia and peripheral neuropathy are extremely predisposing to oropharyngeal dysphagia, which is more commonly associated with muscular dystrophy. OBJECTIVE: To evaluate the clinical characteristics of oropharyngeal dysphagia in Machado-Joseph disease patients. METHOD: Forty individuals participated in this study, including 20 with no clinical complaints and 20 dysphagic patients with Machado-Joseph disease of clinical type 1, who were all similar in terms of gender distribution, average age, and cognitive function. The medical history of each patient was reviewed and each subject underwent a clinical evaluation of deglutition. At the end, the profile of dysphagia in patients with Machado-Joseph disease was classified according to the Severity Scale of Dysphagia, as described by O'Neil and collaborators. RESULTS: Comparison between dysphagic patients and controls did not reveal many significant differences with respect to the clinical evaluation of the oral phase of deglutition, since afflicted patients only demonstrated deficits related to the protrusion, retraction and tonus of the tongue. However, several significant differences were observed with respect to the pharyngeal phase. Dysphagic patients presented pharyngeal stasis during deglutition of liquids and solids, accompanied by coughing and/or choking as well as penetration and/or aspiration; these signs were absent in the controls. CONCLUSIONS: Oropharyngeal dysphagia is part of the Machado-Joseph disease since the first neurological manifestations. There is greater involvement of the pharyngeal phase, in relation to oral phase of the deglutition. The dysphagia of these patients is classified between mild and moderate.

Abstract:

The purpose of this report is to promote early recognition, expeditious evaluation, and judicious management of acute external laryngeal trauma. A retrospective chart review was performed of 112 cases that were managed at a Medical College of Georgia tertiary care hospital by the senior author (E.S.P.). Patients were classified by the time of their presentation, the severity of their injury, and the treatment protocol followed. The clinical outcomes of airway, voice quality, and deglutition were retrospectively reviewed. For voice outcomes, in the delayed treatment group, only 27.7% of patients had a good result, as compared to a 78.3% good result in the early treatment group. Similar differences were demonstrated regarding the airway. In the delayed treatment group, only 73.3% had good airway function, as compared to 93.3% who had good airway function in the early treatment group. Ninety-nine percent of all patients had a good result for deglutition. We conclude that expeditious diagnosis and intervention reduce the incidence of suboptimal clinical outcomes, and with timely and appropriate application of diagnostic and management protocols, the majority of patients will be successfully decannulated (97%) with functional speech (100%) and normal deglutition (99%).

Abstract:

On intensive care patients, decannulation and deglutition disorders are frequent reasons for otorhinolaryngologic assessment. The objective of a tracheostomy is to maintain a patent airway. It does not necessarily prevent episodes of aspiration and may even favor them. When the condition leading to the tracheostomy resolves, a decannulation may be proposed. Deglutition is a complex act that involves the coordinated interaction of several structures of the aerodigestive tract. Fiber-optic endoscopy and videofluoroscopy are two useful and complementary tools for the evaluation of patients with swallowing disorders. When managing these patients, a thorough knowledge on laryngeal and swallowing physiology, and on the different therapeutic alternatives, is required. Although it is not uncommon that swallowing disorders coexist in tracheostomized patients, decannulation is not synonymous with evaluation of deglutition. A patient could be a candidate for decannulation having a swallowing disorder, or a trachostomized patient could swallow adequately. Knowing and understanding these concepts will lead to a more efficient management, and helps to clarify the communication between the intensivist and the otorhinolaryngologist. Ideally, a multidisciplinary team should be formed to evaluate and manage these patients.
