Resumo Introdução A síndrome da apneia obstrutiva do sono é uma desordem de elevada prevalência na população. Estudos constataram possível associação entre obstrução nasal e síndrome da apneia obstrutiva do sono, porém a existência de uma relação entre a intensidade da obstrução nasal e a gravidade da síndrome da apneia obstrutiva do sono ainda não foi comprovada. Objetivo Avaliar as dimensões internas nasais de adultos com ronco primário e síndrome da apneia obstrutiva do sono por meio de rinometria acústica e correlacionar os achados com a gravidade da síndrome da apneia obstrutiva do sono. Método Foram avaliados 21 indivíduos com queixas de ronco e/ou pausas respiratórias durante o sono, gênero masculino, entre 18 e 60 anos, brancos. Após avaliação clínica, exame físico otorrinolaringológico e nasofaringolaringoscopia flexível, todos foram submetidos à polissonografia tipo III. Os participantes foram divididos em dois grupos de acordo com a gravidade dos sintomas: grupo 1, ronco primário e/ou síndrome da apneia obstrutiva do sono leve (n = 9) e grupo 2, síndrome da apneia obstrutiva do sono moderada/grave (n = 12). Dimensões internas nasais foram aferidas por rinometria acústica, foram consideradas para análise as áreas de secção transversa mínima e os volumes de três diferentes segmentos nasais. Resultados O índice de eventos respiratórios correspondeu a 8,1 ± 4,0 no grupo 1 e 47,5 ± 19,1 no grupo 2. No grupo 1, os valores de área de secção transversa, em cm2, corresponderam a: área de secção transversa 1 = 1,1 ± 0,4; área de secção transversa 2 = 2,1 ± 0,9; área de secção transversa 3 = 3,5 ± 1,8. No grupo 2: área de secção transversa 1 = 1,2 ± 0,3, área de secção transversa 2 = 2,0 ± 0,5; áre de secção transversa 3 = 2,8 ± 0,7. No grupo 1 os valores do volume, em cm3, corresponderam a: volume 1 = 3,5 ± 1,0; volume 2 = 9,3 ± 5,0; volume 3 = 40,2 ± 21,5 e no grupo 2 a: volume 1 = 3,6 ± 0,5; V2 = 7,6 ± 1,5; volume 3 = 31,5 ± 6,7. Os valores de área de secção transversa e volume não diferiram entre os grupos. Conclusão Não foram demonstradas diferenças significantes quanto às áreas seccionais transversas e os volumes nasais entre indivíduos com ronco primário e síndrome da apneia obstrutiva do sono leve e síndrome da apneia obstrutiva do sono moderada-grave. Contrariamente à hipótese levantada, os resultados sugerem não existir relação entre as dimensões internas nasais e o nível de gravidade da síndrome da apneia obstrutiva do sono.

Abstract Introduction Obstructive sleep apnea syndrome is a high-prevalence disorder found in the population. Studies have shown a possible association between nasal obstruction and obstructive sleep apnea syndrome, but the existence of a association between the degree of nasal obstruction and obstructive sleep apnea syndrome severity has not yet been proven. Objective To evaluate the internal nasal dimensions of adults with primary snoring and obstructive sleep apnea syndrome by acoustic rhinometry and to correlate the findings with obstructive sleep apnea severity. Methods Twenty-one male Caucasian subjects with complaints of snoring and/or respiratory pauses during sleep, aged between 18 and 60 years of age, were evaluated. After clinical evaluation, otorhinolaryngological examination and flexible nasopharyngolaryngoscopy, all patients underwent type III polysomnography. The participants were divided into two groups according to symptom severity: group 1, primary snoring and/or mild obstructive sleep apnea syndrome(n = 9) and group 2, moderate/severe obstructive sleep apnea syndrome (n = 12). Internal nasal dimensions were measured by acoustic rhinometry, analyzing minimum cross sectional area (CSA) and three nasal segment volumes. Results The respiratory event index corresponded to 8.1 ± 4.0 in group 1 and 47.5 ± 19.1 in group 2. In group 1, the cross-sectional areas values, in cm2, corresponded to: CSA 1 = 1.1 ± 0.4; CSA 2 = 2.1 ± 0.9; CSA 3 = 3.5 ± 1.8 and, in group 2: CSA 1 = 1.2 ± 0.3, CSA 2 = 2.0 ± 0.5; CSA 3 = 2.8 ± 0.7. In group 1, volumes (V), in cm3, corresponded to: V1 = 3.5 ± 1.0; V2 = 9.3 ± 5.0; V3 = 40.2 ± 21.5 and in group 2 a: V1 = 3.6 ± 0.5; V2 = 7.6 ± 1.5; V3 = 31.5 ± 6.7. Cross-sectional area and volume did not differ between groups. Conclusion There were no significant differences in the cross-sectional areas and nasal volumes between individuals with primary snoring-mild obstructive sleep apnea syndrome and moderate-severe obstructive sleep apnea syndrome. Differently to the raised hypothesis, our results suggest that there is no association between internal nasal dimensions and severity of obstructive sleep apnea syndrome.

Abstract Introduction Obstructive sleep apnea is highly prevalent in non-syndromic Pierre Robin sequence patients. Studies have found a probable relationship between obstructive sleep apnea and nasal obstruction and between obstructive sleep apnea and enuresis. Assessment of the relationship between these variables in non-syndromic Pierre Robin sequence patients is scarce. Objective The present study aims to evaluate the relationship between symptoms of obstructive sleep apnea, nasal obstruction and enuresis, determining the prevalence of symptoms suggestive of these conditions, in schoolchildren with non-syndromic Pierre Robin sequence, and describe the prevalence of excessive daytime sleepiness habitual snoring and voiding dysfunction symptoms associated with enuresis. Methods This was a prospective analytical cross-sectional study developed at a reference center. Anthropometric measurements and a structured clinical interview were carried out in a sample of 48 patients. The instruments “sleep disorders scale in children” “nasal congestion index questionnaire” (CQ-5), and the “voiding dysfunction symptom score questionnaire” were used. Statistical analysis was performed for p< 0.05. Results Positive “sleep disorders scale in children” scores for obstructive sleep apnea and CQ-5 for nasal obstruction were observed in 38.78% and 16.33%, respectively. Enuresis was reported in 16.33% of children, being characterized as primary in 71.43% and polysymptomatic in 55.55%; according to the “voiding dysfunction symptom score questionnaire”. There was a significant relationship between nasal obstruction and obstructive sleep apnea symptoms (p< 0.05), but no significance was found between obstructive sleep apnea symptoms and enuresis, and between nasal obstruction and enuresis. The prevalence of excessive daytime sleepiness was 12.24% and of habitual snoring, 48.98%. A family history of enuresis, younger age in years and a positive “voiding dysfunction symptom score questionnaire” score were associated with a higher prevalence of enuresis (p< 0.05). Conclusion Children with non-syndromic Pierre Robin sequence are at high risk for obstructive sleep apnea symptoms and habitual snoring, with a correlation being observed between nasal obstruction and obstructive sleep apnea symptoms. In addition, the study showed that non-syndromic Pierre Robin sequence, obstructive sleep apnea and nasal obstruction symptoms were not risk factors for enuresis in these patients.

Resumo Introdução A apneia obstrutiva do sono apresenta elevada prevalência na população com sequência de Pierre Robin não sindrômica. Estudos constataram provável relação entre apneia obstrutiva do sono e obstrução nasal e entre apneia obstrutiva do sono e enurese, é escassa a avaliação da relação entre essas variáveis na sequência de Pierre Robin não sindrômica. Objetivo Avaliar a relação entre sintomas de apneia obstrutiva do sono, obstrução nasal e enurese, determinar a prevalência de sintomas sugestivos dessas condições, em crianças em idade escolar com sequência de Pierre Robin não sindrômica, assim como descrever a prevalência de sonolência excessiva diurna, ronco habitual e sintomas de disfunção miccional associados à enurese. Método Estudo prospectivo transversal analítico desenvolvido em centro de referência. Fez‐se aferição antropométrica e entrevista clínica estruturada em amostra de 48 pacientes. Os instrumentos usados foram: “escala de distúrbios do sono em crianças”, questionário “índice de congestão nasal” (CQ‐5) e questionário “sistema de escore de disfunção miccional”. A análise estatística foi feita para p < 0,05. Resultados Escores positivos da “escala de distúrbios do sono em crianças” para apneia obstrutiva do sono e do CQ‐5 para obstrução nasal foram observados em 38,78% e 16,33%; respectivamente. Enurese foi relatada em 16,33% das crianças e foi caracterizada como primária em 71,43% e polissintomática em 55,55%; conforme “sistema de escore de disfunção miccional”. Observou‐se relação significante entre obstrução nasal e sintomas de apneia obstrutiva do sono (p < 0,05), porém não significante entre sintomas de apneia obstrutiva do sono e enurese, e obstrução nasal e enurese. A prevalência de sonolência excessiva diurna foi de 12,24% e de ronco habitual, de 48,98%. História familiar de enurese, menor idade em anos e escore positivo na “sistema de escore de disfunção miccional” foram associados a maior prevalência de enurese (p < 0,05). Conclusão Crianças com sequência de Pierre Robin não sindrômica estão sob alto risco para sintomas de apneia obstrutiva do sono e ronco habitual, foi observada correlação entre obstrução nasal e sintomas de apneia obstrutiva do sono. Demonstrou‐se, também, que sequência de Pierre Robin não sindrômica, sintomas de apneia obstrutiva do sono e obstrução nasal não constituíram fator de risco para enurese na população estudada.

RESUMO Objetivo Comparar a geometria da cavidade nasal de crianças e adolescentes com fissura labiopalatina e deficiência maxilar por meio de dois métodos: a tomografia computadorizada de feixe cônico, considerada padrão-ouro, e a rinometria acústica. Método Foram avaliados, de maneira transversal, os exames de tomografia computadorizada de feixe cônico e de rinometria acústica, previamente obtidos para fins de planejamento ortodôntico, de 17 crianças e adolescentes com fissura labiopalatina e atresia maxilar. Por meio do programa Dolphin Imaging 11.8, a cavidade nasal das imagens tomográficas foi reconstruída por dois avaliadores e foram obtidos os volumes internos nasais. Por meio da rinometria, os volumes nasais foram aferidos para as regiões V1 e V2. Os valores de cada exame foram, então, comparados, a um nível de significância de 5%. Resultados A análise estatística mostrou alta reprodutibilidade intra e interavaliadores na análise da tomografia computadorizada de feixe cônico. Os volumes internos nasais médios (± desvio-padrão), utilizando a rinometria acústica e a tomografia computadorizada de feixe cônico corresponderam a 6,6 ± 1,9 cm3 e 8,1 ± 1,5 cm3, respectivamente. A diferença entre os exames foi de 17,7%, considerada estatisticamente significante (p = 0,006). Conclusão Os volumes nasais aferidos pelos dois métodos são diferentes, ou seja, apresentam discrepâncias nas medidas. A técnica considerada padrão-ouro identificou volumes maiores na cavidade nasal. A determinação de qual exame reflete a realidade clínica constitui passo futuro importante.

ABSTRACT Purpose To compare the nasal cavity geometry of children and teenagers with cleft lip and palate and maxillary atresia by two methods: cone-beam computed tomography, considered the gold standard, and acoustic rhinometry. Methods Data on cone-beam computed tomography and acoustic rhinometry examinations of 17 children and teenagers with cleft lip and palate and maxillary atresia, previously obtained for orthodontic planning purposes, were evaluated prospectively. Using Dolphin Imaging 11.8 software, the nasal cavity was reconstructed by two evaluators, and the internal nasal volumes were obtained. Using rhinometry, the volumes of regions V1 and V2 were measured. The values of each examination were then compared at a significance level of 5%. Results Statistical analysis showed high intra- and inter-rater reproducibility in the cone-beam computed tomography analysis. The mean internal nasal volumes (± standard deviation) obtained using acoustic rhinometry and cone-beam computed tomography corresponded to 6.6 ± 1.9 cm3 and 8.1 ± 1.5 cm3, respectively. The difference between the examinations was 17.7%, which was considered statistically significant (p = 0.006). Conclusion The nasal volumes measured via the two methods were different; that is, they presented discrepancies in the measurements. The gold standard technique identified larger volumes than acoustic rhinometry in the nasal cavity. Therefore, determining which test reflects clinical reality is an essential future step.

Abstract Objective: The aim of this study was to assess the accuracy of volumetric reconstruction of the pharynx by comparing the volume and minimum crosssectional area (mCSA) determined with open-source applications (ITK-Snap, www.itksnap.org ; SlicerCMF) and commercial software (Dolphin3D, 11.8, Dolphin Imaging & Management Solutions, Chatsworth, CA, USA) previously validated in the literature. Material and Methods: The sample comprised of 35 cone-beam computed tomography (CBCT) scans of patients with unilateral cleft lip and palate, with mean age of 29±15. Three-dimensional volumetric models of the pharynx were reconstructed using semi-automatic segmentation using the applications ITK-Snap (G1) and Dolphin3D (G2). Volumes and minimum cross-sectional areas were determined. Inter- and intra-observer error were calculated using ICC test. Comparison between applications was calculated using the Wilcoxon test. Results: Volumes and minimum crosssectional area were statistically similar between applications. ITK-Snap showed higher pharynx volumes, but lower mCSA. Visual assessment showed that 62.86% matched the region of mCSA in Dolphin3D and SPHARM-PDM. Conclusion: Measurements of volume and mCSA are statistically similar between applications. Therefore, open-source applications may be a viable option to assess upper airway dimensions using CBCT exams.

Abstract Objective: to assessed the prevalence of diabetes mellitus (DM) and drug abuse in mothers of children with orofacial clefts (OFC). Methods: 325 women who had children (0-3y) with clefts were interviewed. Data regarding type of diabetes, use of legal/illegal drugs during pregnancy, waist girth and fasting blood sugar at the first prenatal consult were collected. Results: twenty seven percent of the women had DM, out of these, 89% had gestational DM, 5,5% type 1 DM and 5,5% type 2 DM. The prevalence of DM in mothers of children with OFC was 27%, it is significantly higher than the average Brazilian population which is 7.6% (p<0.01) (OR=4.5, 95%CI=3.5-5.8). Regarding drug abuse during pregnancy, 32% of the mothers used drugs and a significant positive correlation was observed between drug abuse and the occurrence of clefts and other craniofacial anomalies (p=0.028) (OR=2.87; 95%CI=1.1-7.4). Conclusions: DM and drug abuse during pregnancy increases the risk for OFC and related anomalies and early diagnosis of DM and prevention of drug abuse, especially in pregnant women, should be emphasized.

Conclusões: DM e uso de drogas durante a gravidez aumentam o risco de FOF e anomalias relacionadas e o diagnóstico precoce de DM e a prevenção do uso de drogas, especialmente em mulheres grávidas, devem ser enfatizados.

RESUMO Objetivo Verificar os resultados de inteligibilidade da fala de pacientes submetidos à palatoplastia primária, de acordo com o julgamento perceptivo de cinco examinadores, experientes ou não, no tratamento de fissuras labiopalatinas. Métodos Foram analisados os registros de fala espontânea, armazenados em sistema audiovisual, de 78 pacientes com fissura labiopalatina previamente reparada, de ambos os gêneros, a partir de 4 anos de idade, submetidos à palatoplastia primária. As amostras de fala foram analisadas por cinco diferentes examinadores, que classificaram a inteligibilidade de fala utilizando uma escala de 3 pontos (1=boa, 2=regular e 3=ruim). A concordância interexaminadores foi verificada por meio do coeficiente de Kappa. O sucesso da reabilitação foi analisado descritivamente quanto às proporções de pacientes, de acordo com o grau de inteligibilidade pós-operatória, determinada pelos examinadores. A significância entre as diferenças das proporções obtidas para cada categoria foi verificada pelo teste Qui-quadrado (p<0,05). Resultados A concordância entre os examinadores variou de discreta a substancial. Em mais da metade das amostras os examinadores obtiveram concordância plena. Com base nos valores médios dos julgamentos dos avaliadores, uma proporção significativa dos casos apresentou boa inteligibilidade de fala. Conclusão Verificou-se adequação da inteligibilidade de fala após a palatoplastia primária, na maioria dos casos estudados, sugerindo, assim, que esses pacientes são bem compreendidos em seu meio social. A experiência do avaliador mostrou-se uma variável importante na análise.

ABSTRACT Purpose To verify the results of speech intelligibility in individuals submitted to primary palatoplasty, according to perceptual analysis by five examiners, experienced or not with the treatment of cleft lip and palate. Methods Analysis of spontaneous speech records, registered in audiovisual system, of 78 individuals with repaired cleft lip and palate, of both genders, aged more than 4 years old, submitted to primary palatoplasty. The speech samples were analyzed by five different examiners, who scored the speech intelligibility using a three-point scale (1=good, 2=regular, and 3=bad). The interexaminer agreement was assessed by the Kappa coefficient. The treatment success was analyzed descriptively regarding the proportion of patients according to the postoperative speech intelligibility, as determined by the examiners. Significance between differences was verified by the chi-square test (p<0.05). Results The interexaminer agreement ranged from fair to substantial. Full agreement between the five examiners was observed in more than half of cases. Based on the mean values assigned by the examiners, a significant proportion of cases showed good speech intelligibility after palatoplasty. Conclusion The present outcomes evidenced adequate speech intelligibility after primary palatoplasty in the majority of cases, suggesting that these individuals are well understood in their social environment. The examiner experience presented to be an important variable in the analysis.

Acoustic rhinometry is routinely used for the evaluation of nasal patency. Objective: To investigate whether the technique is able to identify the impairment of velopharyngeal (VP) activity in individuals with clinical diagnosis of velopharyngeal insufficiency (VPI). Methods: Twenty subjects with repaired cleft palate and inadequate velopharyngeal function (IVF) and 18 non-cleft controls with adequate velopharyngeal function (AVF), adults, of both genders, were evaluated. Area-distance curves were obtained during VP rest and speech activity, using an Eccovision Acoustic Rhinometry system. Volume was determined by integrating the area under the curve at the segment corresponding to the nasopharynx. VP activity (ΔV) was estimated by the absolute and relative differences between nasopharyngeal volume at rest (Vr) and during an unreleased /k/ production (Vk). The efficiency of the technique to discriminate IVF and AVF was assessed by a ROC curve. Results: Mean Vk and Vr values (±SD) obtained were: 23.2±3.6 cm3 and 15.9±3.8 cm3 (AVF group), and 22.7±7.9 cm3 and 20.7±7.4 cm3 (IVF group), corresponding to a mean ΔV decay of 7.3 cm3 (31%) for the AVF group and a significantly smaller ΔV decay of 2.0 cm3 (9%) for the IVF group (p<0.05). Seventy percent of the IVF individuals showed a ΔV suggesting impaired VP function (below the cutoff score of 3.0 cm3 which maximized both sensitivity and specificity of the test), confirming clinical diagnosis. Conclusion: Acoustic rhinometry was able to identify, with a good discriminatory power, the impairment of VP activity which characterizes VPI.

The Laboratory of Physiology provides support for the diagnosis of functional disorders associated with cleft lip and palate and also conducts studies to assess, objectively, the institutional outcomes, as recommended by the World Health Organization. The Laboratory is conceptually divided into three units, namely the Unit for Upper Airway Studies, Unit for Stomatognathic System Studies and the Unit for Sleep Studies, which aims at analyzing the impact of different surgical and dental procedures on the upper airways, stomatognathic system and the quality of sleep of individuals with cleft lip and palate. This paper describes the main goals of the Laboratory in the assessment of procedures which constitute the basis of the rehabilitation of cleft lip and palate, i.e., Plastic Surgery, Orthodontics and Maxillofacial Surgery and Speech Pathology.

Treatment of patients with cleft lip and palate is completed with fixed prostheses, removable, total, implants and aims to restore aesthetics, phonetics and function and should be guided by the basic principles of oral rehabilitation, such as physiology, stability, aesthetics, hygiene and the expectations of the patient. In order to obtain longevity of a prosthetic rehabilitation, the periodontal and dental tissue as well as the biomechanics of the prosthesis are to be respected. The purpose of this article is to describe the types of prosthetics treatment, which are performed at HRAC/USP for the rehabilitation of cleft area in adult patients.

This paper presents the treatment protocol of maxillofacial surgery in the rehabilitation process of cleft lip and palate patients adopted at HRAC-USP. Maxillofacial surgeons are responsible for the accomplishment of two main procedures, alveolar bone graft surgery and orthognathic surgery. The primary objective of alveolar bone graft is to provide bone tissue for the cleft site and then allow orthodontic movements for the establishment of an an adequate occlusion. When performed before the eruption of the maxillary permanent canine, it presents high rates of success. Orthognathic surgery aims at correcting maxillomandibular discrepancies, especially anteroposterior maxillary deficiencies, commonly observed in cleft lip and palate patients, for the achievement of a functional occlusion combined with a balanced face.

The aim of this article is to present the pediatric dentistry and orthodontic treatment protocol of rehabilitation of cleft lip and palate patients performed at the Hospital for Rehabilitation of Craniofacial Anomalies - University of São Paulo (HRAC-USP). Pediatric dentistry provides oral health information and should be able to follow the child with cleft lip and palate since the first months of life until establishment of the mixed dentition, craniofacial growth and dentition development. Orthodontic intervention starts in the mixed dentition, at 8-9 years of age, for preparing the maxillary arch for secondary bone graft procedure (SBGP). At this stage, rapid maxillary expansion is performed and a fixed palatal retainer is delivered before SBGP. When the permanent dentition is completed, comprehensive orthodontic treatment is initiated aiming tooth alignment and space closure. Maxillary permanent canines are commonly moved mesially in order to substitute absent maxillary lateral incisors. Patients with complete cleft lip and palate and poor midface growth will require orthognatic surgery for reaching adequate anteroposterior interarch relationship and good facial esthetics.

Cleft lip and palate is the most common among craniofacial malformations and causes several esthetic and functional implications that require rehabilitation. This paper aims to generally describe the several aspects related to this complex pathology and the treatment protocol used by the Hospital for Rehabilitation of Craniofacial Anomalies, University of São Paulo (HRAC-USP) along 40 years of experience in the treatment of individuals with cleft lip and palate.

Patients with cleft lip and palate usually present dental anomalies of number, shape, structure and position in the cleft area and the general dentist is frequently asked to restore or extract those teeth. Considering that several anatomic variations are expected in teeth adjacent to cleft areas and that knowledge of these variations by general dentists is required for optimal treatment, the objectives of this paper are: 1) to describe changes in the innervation pattern of anterior teeth and soft tissue caused by the presence of a cleft, 2) to describe a local anesthetic procedure in unilateral and bilateral clefts, and 3) to provide recommendations to improve anesthetic procedures in patients with cleft lip and palate. The cases of 2 patients are presented: one with complete unilateral cleft lip and palate, and the other with complete bilateral cleft lip and palate. The patients underwent local anesthesia in the cleft area in order to extract teeth with poor bone support. The modified anesthetic procedure, respecting the altered course of nerves in the cleft maxilla and soft tissue alterations at the cleft site, was accomplished successfully and the tooth extraction was performed with no pain to the patients. General dentists should be aware of the anatomic variations in nerve courses in the cleft area to offer high quality treatment to patients with cleft lip and palate.
