Objective The objective of this study was to determine the influence of velopharyngeal (VP) inadequacy on respiratory speech compensations. Design The pressure-flow technique was used to measure pressure, airflow, and timing variables associated with VP closure during the production of the initial plosive consonant /p/ in a series of the utterance “papa.” Setting The study was conducted in the speech and breathing laboratory of the UNC Craniofacial Center. Participants Eighty-two subjects with cleft lip and/or palate were assessed. The subjects were divided into two groups, those with adequate VP closure (VP size <.010 cm2) and those with inadequate VP closure (VP size >0.10 cm2). The adequate group was comprised of 62 subjects, and 20 subjects were categorized as inadequate. Results Peak intraoral pressure decreased in the inadequate group, but the difference was not significant. Nasal airflow increased (p < .01), but duration of the pressure pulse was the same for both groups. The area under the pressure curve decreased for the inadequate group (p = .04). Conclusion These data contrast with previously reported published data using /p/ in the utterance “hamper.” This suggests that phonetic context influences the compensatory response to velopharyngeal inadequacy. Additionally, while the findings are somewhat similar to studies that involved noncleft subjects whose oral airway was suddenly vented during the production of /p/, there is enough difference to suggest that learning also affects the compensatory outcome.

Temporal and respiratory responses to a loss of velar resistance were measured in 107 subjects demonstrating varying degrees of velopharyngeal inadequacy. The subject data were compared to data generated by a mechanical model representing a passive system. The pressure-flow technique was used to estimate velopharyngeal orifice size and measure respiratory and temporal characteristics of aerodynamic events associated with the production of the nasal-plosive blend/mp/in the word "hamper". Subjects were categorized as having adequate closure (<0.05 cm 2 ), adequate/borderline closure (0.05–0.09 cm 2 ), borderline/ inadequate closure (0.10–0.19 cm 2 ) and inadequate closure (⩾ 0.20 cm 2 ). The data revealed that intraoral pressure fell 10-fold in the model as velopharyngeal orifice area changed from adequate closure to inadequate. The subject data demonstrated only a 1.4-fold drop in pressure. Airflow data indicated that there was a 10-fold increase in respiratory volume in the subject data corresponding to the change from adequacy to inadequacy. When respiratory and temporal responses were assessed together, the findings revealed that airflow and temporal changes minimized the fall of pressure as velar resistance declined across groups.

Objective: To describe the clinical course and management of a patient with submucous cleft palate who developed myasthenia gravis (MG) as an adult and suffered recurrent hypernasality. Few reports have described MG patients undergoing pharyngeal flap surgery for velopharyngeal incompetence, and these have described only slight speech improvement in such patients. Design: Case report. Patient: The patient underwent primary pushback palatoplasty and superiorly based pharyngeal flap surgery for submucous cleft and short palate at age 7. Hypernasality showed major improvement after initial surgery. At age 19, the patient developed MG that triggered the recurrence of velopharyngeal incompetence. Intervention: After MG was treated, revision pushback palatoplasty was performed for velopharyngeal incompetence when the patient was 24 years old. Preoperatively and postoperatively, the patient was evaluated by the same speech-language-hearing therapists, each with at least 5 years of clinical experience in cleft palate speech. Results: After the second pushback palatoplasty, hypernasality and audible nasal air emission during speech decreased to mild. Conclusion: Primary pushback palatoplasty and pharyngeal flap surgery were performed for the submucous cleft palate. Revision pushback palatoplasty improved velopharyngeal inadequacy induced by MG. Decreased perceived nasality positively influenced the patient's quality of life. Combined pushback palatoplasty and pharyngeal flap surgery is thus an option in surgical treatment for velopharyngeal inadequacy to close the cleft and the velopharyngeal orifice in cases of cleft palate and MG.

Purpose This article aims to provide a set of guiding principles for interdisciplinary team care of velopharyngeal inadequacy (VPI) for speech, regardless of the etiology. Method A working group of practitioners with advanced training and experience in the management of patients with cleft palate/velopharyngeal disorders, including representatives from speech-language pathology, otolaryngology, and plastic surgery, was formed. Pertinent literature was reviewed, and practical suggestions for clinicians were developed through consensus discussion. Results Seven key principles were identified as being integral to the provision of interdisciplinary team care for VPI. Conclusion Collaborative interdisciplinary team care for persons with velopharyngeal disorders is key to optimal management and outcomes. Practical suggestions for implementing an interdisciplinary team care model for management of cleft-related and noncleft VPI are described.

Purpose The 2 most commonly used operations to treat velopharyngeal inadequacy (VPI) are superiorly based pharyngeal flap and sphincter pharyngoplasty, both of which may result in hyponasal speech and airway obstruction. The purpose of this article is to (a) describe the bilateral buccal flap revision palatoplasty (BBFRP) as an alternative technique to manage VPI while minimizing these risks and (b) conduct a systematic review of the evidence of BBFRP on speech and other clinical outcomes. A report comparing the speech of a child with hypernasality before and after BBFRP is presented. Method A review of databases was conducted for studies of buccal flaps to treat VPI. Using the principles of a systematic review, the articles were read, and data were abstracted for study characteristics that were developed a priori. With respect to the case report, speech and instrumental data from a child with repaired cleft lip and palate and hypernasal speech were collected and analyzed before and after surgery. Results Eight articles were included in the analysis. The results were positive, and the evidence is in favor of BBFRP in improving velopharyngeal function, while minimizing the risk of hyponasal speech and obstructive sleep apnea. Before surgery, the child's speech was characterized by moderate hypernasality, and after surgery, it was judged to be within normal limits. Conclusion Based on clinical experience and results from the systematic review, there is sufficient evidence that the buccal flap is effective in improving resonance and minimizing obstructive sleep apnea. We recommend BBFRP as another approach in selected patients to manage VPI. Supplemental Material https://doi.org/10.23641/asha.9919352

Purpose: This two-part project was designed to test a pressure-sensitive theory of marginal velopharyngeal inadequacy (MPVI). Specifically, are select subgroups of children with MPVI perceived as hypernasal because they fail to achieve consistent closure during vowels and semivowels while demonstrating adequate closure during pressure consonants? Methods: In part one, 36 children with cleft palate and other craniofacial anomalies were examined using a clinical assessment protocol that included nasometry and perceived ratings of hypernasal resonance. Children with nasalance percentages above threshold during low-pressure (LP) productions and below threshold for high-pressure (HP) productions were placed in one group (group 1), while children with nasalance percentages below threshold for both LP and HP sentences were placed in another (group 2). Children in the two groups were age- and sex-matched. In part two, endoscopic data were examined for 10 additional children who received nasometry, perceived hypernasal resonance scores, and videoendoscopy on the same day and who received higher mean nasalance measures during production of LP sentences than during production of HP sentences. Results: The results of part one confirmed that children in group 1 were perceived as being significantly more hypernasal than children in group 2 (meangroup 1 = 2.17, meangroup 2 = 1.50; t = 2.75, p = .01). However, results of endoscopic testing failed to demonstrate a consistent observable physiologic pattern of velopharyngeal inadequacy that would confirm the theory that some patients with MVPI are perceived as being hypernasal because of difficulty achieving velopharyngeal closure during vowels and semivowels. Conclusions: The findings provide partial support for a pressure-sensitive theory of MVPI and demonstrate the value of using both HP and LP sentences to evaluate patients with MVPI.

The topic of this diploma thesis is an analysis of interdisciplinary approach to children with orofacial clefts. The first chapter deals with theoretical base and defines terminology - communication, communication disabilites. It also defines anatomy and physiology of nasal cavity and oral cavity. The second chapter relates to issues of orofacial clefts. It describes classification, etiology, symptomatology, prevention, aestetic and psychosocial impacts and orofacial cleft children care. The third chapter deals with occurence of communication disabilites of children with orofacial clefts. It focuses on the definition of palatholaly, velopharyngeal inadequacy and it describes various linguistic levels and speech therapy and intervention. The fourth chapter is empiric and it deals with analysis of interdisciplinary approach to children with orofacial clefts. In research processes there were used scientific literature analysis, anamnestic data analysis and available specialized materials analysis. Based on all of these materials six case studies were created. Main goal of this empiric chapter was to analyze interdisciplinary approach to children with orofacial clefts. Partial goals were to analyze whether information provided by experts and doctors to parents of newborn children with orofacial cleft...
