“…23 In accordance with the objective of the present study to specifically assess the nasal cavity and not the pharynx, it can be stated that the influence of BMI is not clinically relevant, as neither air resistance nor the size of the nasal cavity seems to be influenced by obesity. 30 Furthermore, previous studies 26,31 by our group showed that age and gender do not significantly influence the minimal cross-sectional area of the nasal cavity. Another factor that varied between study participants was gender.…”

“…However, normative data of the nasopharyngeal minimal cross-sectional area, measured by anterior modified rhinomanometry in individuals without CL/P, obtained in a study conducted in the same setting as the present, showed no difference between genders. 31 Considering these data, it seems unlikely that the statistically significant difference found between G1 (CL/P + OSA) and G2 (N-CL/P + OSA) for the upper segment of the nasopharynx in our study was influenced by gender. However, due to the reduced sample size, this bias effect should be considered when interpreting nasal dimensions results.…”

To evaluate nasal cavity (NC) dimensions of individuals with cleft lip and/or palate (CL/P), obstructive sleep apnea (OSA), and primary snoring, by tomographic image analysis, compared to individuals with OSA without CL/P (N-CL/P). Cross-sectional and retrospective. Tertiary referral center. Patients were divided into 2 groups: (G1) CL/P + OSA or primary snoring, n = 11; (G2) N-CL/P + OSA, n = 13. NC tomographic images were reconstructed using ITK-SNAP software, and measurements were obtained from these three-dimensional models using SpaceClaim software. Total NC volumes, right and left NC volumes, and volumes of the nostril to the nasal valve (V1) and from the nasal valve to the superior limit of the nasopharynx (V2), cross-sectional areas, and perimeters. NC volumes (total, right, and left sides), V1, and V2, though smaller in the CL/P + OSA, did not differ significantly from the N-CL/P + OSA. Cross-sectional areas and perimeters of the superior limit of the nasopharynx, in the CL/P + OSA, presented significantly higher values compared to the N-CL/P + OSA ( P ≤ .05). The internal nasal dimensions of patients with CL/P do not seem to be part of the etiopathogenesis, nor constitute a risk factor for OSA with greater severity, in this special group of patients.

“…Fonte: Adaptada de Amorim 17 e Rollemberg et al 18 Algumas funções biológicas, como a fala e a respiração, são comprometimentos decorrentes das anomalias craniofaciais, especificamente as fissuras labiopalatais. Contudo, apesar de um primeiro reparo cirúrgico do palato e lábio, as alterações nasais são comuns, resultando na diminuição das dimensões da cavidade dessa estrutura, logo, aumentando de forma significativa o número de respiradores orais 20 . De acordo com estudos, cerca de 60% de pessoas com fissura labiopalatal possuem a via aérea nasal prejudicada e consequente respiração através da via bucal que, por conseguinte, influencia o funcionamento das vias aéreas inferiores e funções da mastigação e deglutição, além do próprio ato de falar 20 .…”

As ﬁssuras labiopalatais são más formações congênitas que acometem a face, mais especificamente no terço médio com comprometimento do osso maxilar e ocorrem devido à falta de junção dos processos maxilares e médio nasal. A etiologia destas alterações encontra-se condicionadas a uma série de fatores ambientais e genéticos e o seu tratamento deve ser realizado de forma precoce. O objetivo desse estudo foi, mediante uma revisão de literatura, avaliar as evidências científicas disponíveis na literatura, sobre as fissuras labiopalatais para possibilitar ao leitor uma construção de conhecimento sobre o tema de forma reflexiva. Esse estudo se baseou em uma busca de dados nas seguintes bases bibliográficas: Web of Science, PubMed, EMBASE, SCIELO e LILACS, com o corte temporal de 2008 a 2021. Podemos concluir que as fissuras labiopalatais ainda são alterações patológicas bem frequentes e os profissionais devem possuir conhecimentos, mesmo que básico, a respeito dessas anomalias desde a etiologia até o tratamento para estarem preparados em situações em que devem orientar os responsáveis legais pelo paciente.

“…This technique is based on the principle that a constriction area may be estimated by simultaneous measurement of the differential pressure between the two sides of constriction and the airflow crossing it (5,24) . The nasopharyngeal area is measured during respiration at rest, positioning a catheter inside the oral cavity and another inside the nostril with smaller nasal flow, held in place by an obturator.…”

“…The area considered for analysis corresponds to the mean of these multiple measurements and is calculated by the equation: A= V/k (2ΔP/d)1/2, in which A= orifice area in cm 2 ; V= nasal flow in cm 3 /s; K= 0.65; ΔP= oral-nasal pressure in dynes/cm 2 ; d= air density (0.001g/cm 3 ) (12) . The value of 1.047cm 2 was considered as the limit or normality (24) .…”

Introduction: Secondary palatoplasty with intravelar veloplasty (IV) may be performed before pharyngeal flap (PF) for surgical treatment of velopharyngeal insufficiency in individuals with cleft palate. This surgical approach aims to improve the velopharyngeal conditions, thus avoiding indication of a large pharyngeal flap and its undesirable effects on respiration. Purpose: To investigate the effects of pharyngeal flap performed after intravelar veloplasty for the treatment of velopharyngeal insufficiency on nasality and respiration. Methods: Analysis of postoperative outcomes of speech nasality and respiration in 50 individuals with repaired cleft palate and velopharyngeal insufficiency, being 23 submitted to pharyngeal flap after intravelar veloplasty (Group IV+PF) and 27 submitted only to pharyngeal flap (Group PF). Nasality was determined by nasometry, and the effect of surgery on respiration was assessed by measuring the minimum nasopharyngeal transverse section area, obtained by the pressure-flow technique and investigation of respiratory complaints, using a specific questionnaire. Statistical comparison between groups was performed by the Mann-Whitney test and Student t test, at a significance level of p<0.05. Results: There was no difference between groups for the outcomes of nasality, measurement of nasopharyngeal area and investigation of respiratory complaints. Conclusion: Both approaches for surgical treatment of velopharyngeal insufficiency demonstrated similar outcomes concerning the elimination of hypernasality, as well as for respiration, suggesting that accomplishment of pharyngeal flap after intravelar veloplasty did not provide better speech resonance outcomes nor favored respiration.
