A hipertrofia de adenóide promove uma diminuição do espaço livre da nasofaringe e se constitui em uma das principais causas da respiração bucal. Entre os métodos utilizados para o diagnóstico desta condição, os mais precisos são a endoscopia nasal e a ressonância magnética, por permitirem a visualização da nasofaringe em três dimensões. No entanto, o método mais utilizado, em Odontologia, é a radiografia cefalométrica lateral. Torna-se, portanto, de grande importância, a verificação da eficiência deste método de diagnóstico. Este trabalho foi realizado com o objetivo de determinar a eficácia da radiografia cefalométrica lateral no diagnóstico da hipertrofia de adenóide, pela comparação deste método com a endoscopia nasal. Foram avaliados 30 indivíduos (7 a 12 anos) sem história prévia de cirurgia otorrinolaringológica. Todos fizeram um exame de endoscopia nasal e uma radiografia cefalométrica lateral. Nas endoscopias, foi registrada a porcentagem de obstrução da nasofaringe, e nas radiografias, a menor dimensão ântero-posterior livre da nasofaringe. Os valores encontrados pelos dois exames se mostraram fortemente correlacionados (r = ? 0,793, p-valor < 0,01). Em seguida, foram realizados os testes de validade e confiabilidade para o diagnóstico radiográfico. Para isso, foram considerados portadores de hipertrofia severa de adenóide, os pacientes que apresentaram, na endoscopia, obstrução da nasofaringe igual ou superior a 75% e, nas radiografias, o menor diâmetro antero-posterior da nasofaringe igual ou inferior a 5 mm. O exame radiográfico teve uma sensibilidade de 75%, especificidade de 86,3%, valor preditivo positivo de 66,7%, valor preditivo negativo de 90,4% e a exatidão foi de 83,3%. A radiografia cefalométrica lateral, então, se mostrou um exame eficiente para o diagnóstico da hipertrofia de adenóide, o que foi comprovado pela forte correlação entre os seus resultados e os da endoscopia nasal, que é considerado o exame padrão-ouro para o diagnóstico desta condição.

Full textThe aim of this study was to evaluate the nasal cavity of dogs, presented with chronic nasal disease, through rhinoscopy. In addition to checking the reliability of nasal biopsy results, rhinoscopy was used to identify the type and location of lesions and to relate them to the clinical and radiographic findings. Furthermore, we also gathered epidemiology data related to breed, age, weight and gender. For the purpose of this study we used 38 dogs that presented clinical signs and radiographic alterations compatible with chronic nasal disease. Regarding the epidemiology, the highest incidence of nasal diseases was noticed in mixed breed dogs. Also, nasal disease was more frequent in adult, male, large or medium sized dogs. The majority of nasal diseases were due to tumors, and in this regard the transmissible venereal tumor (TVT) was the most frequent and was mainly diagnosed in mixed breed, male, adult dogs. Mesenchymal neoplasia were the second most frequent alteration of the nasal cavity, followed by, epithelial neoplasia, polyps, chronic rhinitis, foreign bodies and aspergillosis. Rhinoscopy guided biopsy proved to be effective except in the case of mesenchymal tumors. The results of this study prove that rhinoscopy is an effective non-invasive diagnostic tool, which complements physical and radiological examination. Moreover, this study also shows that the association of anterior and posterior rhinoscopy techniques, allow for a wide visualization of the nasal cavity and determination of the biopsy location and collection of samples for culture. In additional, rhinoscopy is a useful tool for diagnosis and removal of foreign bodies.

Full textRhinosinusitis is a frequent cause of fever in Intensive Care Unit (ICU) patients. Diagnosis is sometimes delayed because of lack of clinical signs and it may lead to complications such as meningitis, pneumonia and sepsis. The severity of these complications requires active search for the sinusal infectious focus in the presence of fever of undetermined cause. Computed tomography scan is the gold standard for such investigation. However, studies have demonstrated the frequent occurrence of radiological rhinosinusitis with no correlation with sinusal infection. Nasal endoscopy is a method that enables the assessment of nasal cavities, specially the region of middle meatus and sphenoethmoid recess. This fact has transformed nasal endoscopy into a fundamental exam to assess patients with clinical suspicion of rhinosinusitis. The purpose of the present study was to assess the efficacy of nasal endoscopy as a diagnostic method for rhinosinusitis detection in ICU patients. From June 2003 to August 2006, thirty consecutive patients hospitalized in the ICU who presented clinical picture and tomography results suggestive of rhinosinusitis were submitted to nasal endoscopy. We included only patients with indication of surgical drainage as management option, which was the adopted diagnostic confirmation of rhinosinusitis. Endoscopy was performed before surgical drainage to assess the presence of edema and rhinorrhea in the middle meatus and sphenoethmoid recess. We used anesthesia and topical vasoconstriction of nasal fossa, middle meatus and sphenoethmoid recess before the endoscopic assessment. The results of nasal endoscopy did not interfere in the therapy prescribed to each patient, who was determined by the Intensivists of the Discipline of Clinical Emergency, together with the Otorhinolaryngologists of the Department of Otorhinolaryngology, Hospital das Clinicas, Medical School, University of Sao Paulo. Among the 30 patients with suspicion of rhinosinusitis included in the study, 21 presented diagnostic confirmation through surgical drainage. Computed tomography showed sensitivity of 97.3% and specificity of 16.2% for the diagnosis of rhinosinusitis. In the presence of edema, endoscopy showed sensitivity of 85% and specificity of 32%. In the diagnosis of rhinorrhea, sensitivity was 67.6% and specificity was 90.4%, and accuracy was 85%. We concluded that nasal endoscopy is an effective method for the diagnosis of rhinosinusitis in intensive care unit patients, especially in the presence of rhinorrhea.

Full textA hiperplasia de tonsila faríngea é uma das principais causas de respiração oral. O diagnóstico preciso desta alteração é importante para o correto planejamento terapêutico. Em vista disso, estudos têm sido desenvolvidos a fim de fornecer subsídios quanto aos procedimentos que podem ser utilizados para o diagnóstico de obstrução faríngea. Objetivo: Verificar a correlação entre os exames de nasofibrofaringoscopia e cefalometria no diagnóstico de hiperplasia de tonsila faríngea. Material e Métodos: Participaram deste estudo 55 crianças, 30 meninas e 25 meninos, com idades entre sete e 11 anos. As crianças foram submetidas à avaliação nasofibrofaringoscópica e cefalométrica para a determinação do grau de obstrução da nasofaringe. Para verificar a correlação entre esses exames foi utilizado o coeficiente de correlação de Spearman ao nível de significância de 5%. Resultados: Na nasofibrofaringoscopia a maioria das crianças apresentou hiperplasia de tonsila faríngea graus 2 e 3, seguidas de grau 1. Na cefalometria a maior parte das crianças apresentou hiperplasia de tonsilas faríngeas grau 1, seguida de grau 2. Na correlação entre os exames, evidenciou-se correlação regular e positiva. Conclusão: A avaliação da hiperplasia de tonsilas faríngeas pode ser realizada pela nasofibrofaringoscopia e pela cefalometria, pois estes exames apresentam uma relação regular e positiva. No entanto, verificou-se que a cefalometria tende a subestimar o tamanho da tonsila faríngea em relação à nasofibrofaringoscopia.

Full textINTRODUCTION: Even though the success rate of sphenopalatine ligation is greater than 95%, some authors have reported some difficulties in isolating those arteries during endoscopic surgical procedure. The failure rate of the sphenopalatine artery ligation or cauterization may vary from 2% to 10%. Some anatomical variations on the nose lateral wall are reported, with reference to the sphenopalatine foramen (SPF) location, the presence of an accessory foramen, arteries ramification and SPF dimension and morphology. Anatomical variation of the region, as well as scarcity of endoscopic studies showing landmarks to find the sphenopalatine artery and its branches may justify surgical failure. OBJECTIVE: The purpose of this study was to describe the anatomy of SPF region and possible anatomical variations, during the endoscopic cadaver dissection and to observe the symmetry between nasal sides and the relationship to gender and racial group. CASUISTICS AND METHODS: It is a prospective anatomical study developed from September, 2006 to January, 2007. The SPF of 61 fresh cadavers (122 nasal fossae) was carefully endoscopic dissected. Male (75%) and mixed race cadavers prevailed. Presence of ethmoidal crest, location of sphenopalatine and accessory foramens, number of arterial branches emerging through foramens and distances from the foramens to anterior nasal spine were observed. Data were analyzed in relation to gender, racial group and symmetry of the same cadaver. Prediction of the presence of accessory foramen was evaluated in relation to number of arterial branches emerging through SPF, SPF location and distance from the SPF to the anterior nasal spine. RESULTS: Ethmoidal crest was present in 100% of cadavers, being anterior to the SPF in 98.4% of times. The most frequent SPF location was the transition region of middle and superior meatus (86.9%). Mean distance from SPF and accessory foramen to anterior nasal spine was 6.6cm and 6.7cm, respectively. Accessory foramen was present in 9.83% of cases. A single arterial stem emerged through the SPF in 67.2% of times, and 100% through accessory foramens. The prevalence analyses showed no differences statistically significant (p>0,05) between gender and racial group. The symmetry analyses showed a strong conformity (Kappa index 0,71/p<0,01) between nasal fossae in relation to the SPF location; and a poor conformity (Kappa index 0,22/p=0,03) in relation to the number of arterial branches emerging through the SPF. There was no statistically significant conformity between nasal fossae and the presence of accessory foramen (p = 0,53). None of the variables of interest presents any statistically significant (p>0,05) association with the presence of the accessory foramen. CONCLUSIONS: Anatomical variations in the lateral nose wall exist, and should be taken into account, for a well-succeeded endoscopic surgical treatment of severe epistaxis.

Full textIntroduction: Continuous Positive Airway Pressure (CPAP) is the gold standard treatment for obstructive sleep apnea (OSA) and was conceived to be applied by nasal route only. However, in clinical practice the oronasal mask is commonly used. This study was designed to determine the acute effects of changing the nasal CPAP route to oronasal and oral in upper airway patency during sleep in patients with. We hypothesized that the pressure transmitted by the oral compartment of oronasal mask will push the tongue backwards and will compromise CPAP effectiveness in OSA treatment. Methods: Eighteen patients with OSA (age: 44±9 years44±9 years44±9 years44±9 years44±9 years44±9 years44±9 years44±9 years44±9 years , body mass index: 33.8±4.733.8±4.733.8±4.7 33.8±4.7 33.8±4.7 Kg/m², apnea-hypopnea index: 49.0 ± 39.149.0 ± 39.149.0 ± 39.149.0 ± 39.149.0 ± 39.149.0 ± 39.1 49.0 ± 39.149.0 ± 39.149.0 ± 39.1 events/hour) slept with a customized oronasal mask with a nasal and oral sealed compartments connected to a multidirectional valve. Sleep was monitored by full polysomnography and induced by low dosis of midazolam (3.1 ± 2.2 mg). Nasal CPAP was titrated up to holding pressure and flow route was changed to oronasal (n = 18) and oral route (n = 16) during sleep. Retroglossal area was continuously observed by nasoendoscopy. Results: Nasal CPAP (14.8±4.1 cmH2O) was able to stabilize breathing in all patients. In contrast, CPAP delivered by oronasal and oral route promoted obstructive events in 12 (66.7%) and 14 (87.5%) patients, respectively. Compared to stable breathing during nasal route, there was a significant and progressive reduction in the distance between epiglottis and tongue base and the retroglossal area when CPAP was delivered by oronasal and oral route, respectively. Conclusions: CPAP delivered by oronasal route may compromise CPAP effectiveness to treat OSA

Full textBackground: Nasal anatomical variations can impair the visibility on endoscopic transsphenoidal approach for pituitary tumors. Objective: To evaluate anatomical variations, mainly nasal septum deviation, and their impact on the visibility of transsphenoidal endoscopic approach. To support the decision of access type or need to correct the deviated septum. Methods: Cross-sectional study with 38 patients who underwent transsphenoidal endoscopic surgery using the two nostrils - four hands between February 2009 and January 2011 in a referral center. They were submitted to the intraoperative register of anatomical variations, septal deviations, surgical corridor width and location of the deviated septum (height and depth), depth of the access to sphenoid and sella, exposure of sphenoid and sella after opening. Visibility was assessed using an ordinal scale: 0- no difficulty, 1- low to moderate difficulty, 2- severe difficulty. Comparisons of two means were performed using Students t test, and three or more means using analysis of variance (ANOVA) with Turkeys complementary test. Correlations between scores were analyzed using the non-parametric chi-square test and the likelihood ratio. Results: Seventy-six nasal cavities were studied, and 50 septal deviations were found (66%). Among the patients with severe difficulty, 73% had a surgical corridor width in the location of the deviated septum of up to 9 mm (p < 0.001). Septal deviations in the middle level (p = 0.005) or posterior third (p < 0.001) were associated with severe difficulty. The width of the nasal cavity at the deviation was also smaller in the middle level (8.41 mm, p = 0,012) or posterior third (6.9 mm, p<0.001). In the surgical corridor, only the middle meatus was associated with difficulty (5 to 13 mm, 73% severe difficulty, p = 0.001). Anatomical variations of the nasal conchae were observed in 17% of cases with no impact on visibility. The average length of the nasal septum was 64 mm (95% CI 61.8 -66.8 mm); the mean depth to the sphenoid was 69 mm (95% CI 67-71 mm) and to the sella 82 mm (95% CI 80.2 - 83.8 mm). The average lateral exposure of the sphenoid was 20 mm and anteroposterior 20.8 mm and to the sella 12.8 mm and 11.7 mm respectively. Conclusions: The width of nasal cavity at deviation and site of septal deviation were associated with difficulty in visibility of the access. Septal deviations located at posterior third and at middle level in nasal cavities were strongly associated with difficulty

INTRODUÇÃO: A hipertrofia adenoideana é uma das causas mais comuns de doença na população pediátrica e motivo freqüente de intervenção cirúrgica nesta faixa etária. O paciente com essa alteração apresenta sintomas de roncos, respiração bucal e obstrução nasal principalmente e de forma mais intensa quando em decúbito dorsal. A videoendoscopia nasal é considerada o exame padrão-ouro para avaliação da hipertrofia adenoideana e é realizada com o paciente sentado. Sendo os sintomas causados por esta alteração piores quando o paciente está deitado, o objetivo foi comparar a obstrução da via aérea pela adenóide nas posições sentada e decúbito dorsal. MÉTODOS: Os participantes foram crianças com idade entre 2 e 12 anos que procuraram o serviço de otorrinolaringologia espontaneamente com queixa de ronco e/ou obstrução nasal. Os pacientes foram submetidos à videoendoscopia nasal sentados e deitados, pelo mesmo examinador. Uma imagem da nasofaringe posterior foi obtida de cada fossa nasal de cada paciente nas duas posições. A área livre da nasofaringe foi medida e comparada em ambas posições para cada paciente, estabelecendose uma razão. A média das razões de todos pacientes foi obtida. A análise das imagens foi feita por dois pesquisadores diferentes daquele que procedeu ao exame, sem ter conhecimento da posição e lado de cada uma delas. RESULTADOS: Quarenta e oito crianças foram incluídas. A área livre da nasofaringe obtida com o paciente sentado foi, em média, 53% maior que a área livre medida com o paci nte deitado (intervalo de confiança: 95%; p<0,001). CONCLUSÃO: A obstrução adenoideana é maior quando o paciente é submetido à videoendoscopia nasal em decúbito dorsal. Nesta posição o exame é mais confiável, reproduzindo melhor os sintomas dos pacientes. Tal acurácia é essencial visto que pode influenciar na decisão de intervenção cirúrgica desta importante e freqüente alteração da população pediátrica. ______________________________________________________________________________ ABSTRACT
INTRODUCTION: Adenoid hypertrophy is one of the most common diseases in the pediatric population and a common reason for surgical intervention in this age group. The patient with this condition develops the symptoms of snoring, mouth breathing and nasal obstruction, especially more intense when recumbent. The nasal videoendoscopy is considered the gold standard exam for assessment of adenoid hypertrophy and is performed with the patient sitting. Since the symptoms caused by this condition are worse when the patient is lying down, we sought to compare adenoid airway obstruction in the sitting and recumbent positions. METHODS: Participants were children beetwen the ages of 2 and 12 years who sought the department of otorhinolaryngology spontaneously complaining of snoring and / or nasal obstruction. Patients underwent nasal videoendoscopy sitting and lying performed by the same investigator. An image of the posterior nasopharynx was obtained from each nasal cavity of each patient for both positions. The free area of the nasopharynx was measured and compared in both positions. Image analysis was performed by two different researchers. These investigators made a blinded analysis because they did not know the positions in which the patients had the images recorded. RESULTS: 48 children were included. The nasopharynx free area obtained with seated patient is, on average, 53% bigger than the free area obtained while patient was lying(confidence interval: 95%; P<0.001). CONCLUSIONS: Adenoidal obstruction is bigger whem the exam is performed with the patient lying. In this position, testing is more reliable, better reproducing the patient's symptoms. Such accuracy is essential since it influences the decision of su rgical intervention in this important and widespread change in the pediatric population.

Full textThe pericranial flap (PCF) has been commonly used in craneo-facial and skull base reconstructions. However, the advance of endoscopic techniques has relegated the use of PCF. At the same time, this advance represents an opportunity to extend the indications of the PCF to those endoscopic approaches in which the endonasal flaps are not available. The aims of this study is to analyze the use of the PCF in the endoscopic reconstruction of the skull base and the nasal septum. An anatomical study on fresh cadaver specimens in which reconstructions of the different skull base defects and nasal septum were carried out. The PCF was introduced through an osteotomy of the frontal sinus. Then, the defects were endoscopically repair. A radiological analysis in computed tomography was performed. The reconstruction limits allowed by the PCF and the standardization of the size of the PCF according to the defect were measured. A clinical study is performed in patients with tumors of the skull base and total septal perforation. In the anatomical study, the nasal septum length and the PCF length and area were obtained. In all the specimens, the total reconstruction of the defects was achieved. The radiological study determined that to reconstruct defects secondary to transcribriform, transtuberculum, clival and craniovertebral approaches, the distal incision of the PCF should be placed respectively at -3.7 ± 2.0 cm, -0,2 ± 2,0 cm, +5,5 ± 2,3 cm, +8,4 ± 2.4 cm, from the reference point (external auditory canal). For total repair of the septum, the distal edge of the PCF should be located 0.8 ± 2.0 cm from the reference point. Defects of the skull base (n = 6) and total septal perforation (n = 1) in our clinical cohort were completely reconstructed. This work concludes that the CP presents enough area for the endoscopic reconstruction of the different approaches of the skull base and total septal perforation. The use of the frontal sinus as the entrance and the endoscopic management of the CP in the reconstructions is a feasible and simple technique.

Full textObjectives/Hypothesis: To evaluate the impact of endoscopic partial inferior turbinectomy (EPIT) associated with primary Rhinoseptoplasty on quality of life outcomes (QOL), complications, and surgical duration. Study Design: Randomized clinical trial. Methods: Individuals with nasal obstruction aged ≥ 16 years who were candidates for functional and aesthetics primary Rhinoseptoplasty were evaluated from March 2014 through May 2015 at a tertiary university hospital in Brazil. Eligible participants were randomly allocated to rhinoseptoplasty with or without EPIT. Outcomes: Absolute change (postoperative –preoperative) in the following QOL scores: Nasal Obstruction Symptom Evaluation-Portuguese (NOSE-p), Rhinoplasty Outcome Evaluation (ROE) and World Health Organization Quality of Life (WHOQOL)-bref (to measure general QOL). Outcomes were blindly assessed 3 months postoperatively. The protocol was registered at ClinicalTrials.gov (NCT02231216). Results: Fifty patients were studied. Most were Caucasian and had moderate/severe allergic rhinitis symptoms. Mean age was 36 (±14.5) years. Rhinoseptoplasty was associated with improvement in all QOL scores irrespective of turbinate intervention (P <0.001). ANCOVA was conducted to control for potential confounders. There was no difference between the groups in absolute score changes for NOSE-p (-50.5 vs. -47.6; P=0.723); ROE (47 vs. 44.8; P = 0,742), and all WHOQOL-bref score domains (P >0.05). There were no differences between the groups regarding presence of the complications. Surgical duration was higher in the EPIT group (212 minutes ± 7.8 vs. 159.1 ± 5.6; p ˂ 0.001). Conclusions: Turbinate reduction through EPIT during primary rhinoseptoplasty did not improve short-term general and specific QOL outcomes. The use of EPIT increases surgical time considerably without improving QOL scores. There was no difference in postoperative incidence of complications, suggesting that EPIT is a safe technique.

Full textTratamentos cirúrgicos para a obstrução da via aérea nasal são comuns na prática em otorrinolaringologia. A cirurgia do septo nasal é a terceira cirurgia mais realizada em ORL nos Estados Unidos da América. É uma técnica que se tem sofrido alterações nos últimos dois séculos, nos quais foram derrubados muitos dos obstáculos inerentes à mesma. Elaborou-se esta revisão de forma a rever quais foram os avanços ao longo do tempo, que opções existem nos dias de hoje, tentar perceber quais são alguns dos próximos passos e qual o rumo a seguir no futuro. A técnica endoscópica melhorou bastante os resultados por meio de uma identificação mais exata da patologia, minimizar o risco hemorrágico intraoperatório, bem como representar uma ótima ferramenta pedagógica. No futuro, as indicações para Tomografia Computorizada dos seios perinasais podem alargar com o avanço da técnica de baixa radiação, bem como a redução de custos da mesma. A cirurgia do septo nasal evoluiu bastante ao longo dos anos com o aparecer de variadas técnicas. Continua, no entanto, a ser um procedimento desafiante para o otorrinolaringologista. Não há um plano único que sirva todos os doentes. É essencial uma boa avaliação da localização e gravidade das alterações e planear caso a caso.
Surgical treatment for Nasal airway obstruction are common practice in otolaryngology. The surgery of the nasal septum is the third most performed in otolaryngology, in the USA. This technique has changed over the last two centuries, in which many obstacles were tackled. An article review was carried out in order to revisit the advances through time, what options are available today, try to understand some of the next steps and what is the course for the future. Endoscopy was a major improve for the results due to a more exact identification of the pathology, minimizing the intraoperatory hemorragic riscs, and stand as a prime teaching tool. In the future, the indication for the perinasal sinus computorized tomography can widen with the enhancement of the low dose radiation technique, as well as the costs of it. The surgery of the nasal septum has evolved a lot through the years, and with the advent of many techniques. It still remains challenging for the otolaryngologist. There is no sigle plan that suits every patient. A good evaluation of the location and severity of the deviation is essencial, as well as planning each case individually.

Full textAo longo da segunda metade do século XX, assistiu-se a uma evolução progressiva da abordagem cirúrgica da patologia naso-sinusal, inicialmente focada na remoção da mucosa, com recurso a técnicas rudimentares e radicais, associadas a uma maior taxa de complicações e morbilidade, até à introdução do endoscópio e do conceito de FESS (Cirurgia Endoscópica Funcional dos Seios Peri-Nasais), que veio estimular a realização de procedimentos funcionais, com preocupação pela preservação da mucosa, visando o diagnóstico e cirurgia minimamente invasivos. O desenvolvimento da instrumentação, bem como tecnológico, com recurso a dispositivos de última geração, tecnologia de alta definição e cirurgia orientada por imagem computorizada, vieram transformar não só a abordagem da patologia naso-sinusal, como também permitiram a expansão das aplicações da cirurgia endoscópica para além das patologias de natureza essencialmente inflamatória e confinadas à cavidade nasal e seios peri-nasais, incluindo tumores naso-sinusais, patologias da base do crânio e da cavidade orbitária. O objetivo desta revisão passa por abordar de forma sistemática a evolução da cirurgia endoscópica nasal e dos seios peri-nasais até à atualidade, não só de uma perspetiva técnica como também relativamente à sua aplicabilidade, visando ainda promover a discussão sobre o que o futuro reservará a este que é um dos procedimentos de Otorrinolaringologia mais frequentemente realizados atualmente e que transformou por completo a prática em Rinologia.
During the second half of the 20th century, there was a progressive evolution of the surgical approach to sinonasal pathology, initially focused on mucosal removal, using rudimentary and radical techniques, associated with a higher rate of complications and morbidity, until the introduction of the endoscope and the concept of FESS (Functional Endoscopic Surgery of the Paranasal Sinuses), which allowed the performance of functional procedures, with concern for the preservation of the mucosa, aiming at minimally invasive diagnosis and surgery. The development of instrumentation, as well as technological advancements, such as the latest generation devices, HD technology and image-guided surgery, have transformed not only sinonasal pathology approach, but also allowed the expansion of endoscopic surgery applications beyond inflammatory pathologies confined to the nasal cavity and paranasal sinuses, to sinonasal tumors, skull base and orbital procedures. This review will address the evolution of endoscopic nasal and sinus surgery, not only from a technical perspective but also with regard to its applicability, aiming at furthering the discussion of what the future holds for this surgical procedure, which is one of the Otorhinolaryngology procedures most frequently performed nowadays and that has profoundly transformed the practice in Rhinology.
