ABSTRACT

O objetivo deste estudo foi avaliar a morfologia/crescimento craniofacial e a oclusão dentária em pacientes (ambos sexos), entre 4 e 10 anos e aumento adenoamigdaliano com e sem otite média secretora (OMS). Utilizou-se análise cefalométrica e modelos de estudo dentários. Não foram observadas diferenças significativas entre os grupos estudados, em relação às medidas lineares e angulares adotadas, exceto, a medida correspondente ao comprimento do palato ósseo (ENA-ENP), que mostrou relação com a idade e a OMS. Não houve um tipo facial predominante. Observou-se discreta predominância de mordida profunda, mordida cruzada posterior e desvio da linha média em relação à OMS, porém sem significância estatística. A atresia maxilar pode estar associada à OMS, assim como sua redução pode estar relacionada ao crescimento e desenvolvimento craniofacial.


The aim of this study was to evaluate the craniofacial growth/morphology and dental occlusion in 100 patients (male and female) from 4 to 10 years old and tonsils and adenoid enlargement. There were two groups: with and without otitis media with effusion (OME). We used the cephalometric analyses and dental casts. It was not observed significant differences between the two groups, in relationship to the linear and angular measurements adopted, except for the measurement corresponding to the palate bone length, which had shown correlation with age and OME. It was not found a facial pattern predominance. It was observed a discreet predominance of deep bite, posterior cross bite and midline deviation to OME, however without statistical significance. The maxillary narrowing might be associated to OME as well as its reduction may be related to the craniofacial growth and development.

ABSTRACT

A face de cada um de nós apresenta características únicas. Resultado da combinação de tipos variados de mandíbulas, maxilas, órbitas, é o que nos faz reconhecer cada indivíduo. As crianças apresentam proporções faciais distintas dos adultos. O processo de crescimento e desenvolvimento craniofacial é influenciado por diversos fatores: tanto sistêmicos (genéticos, metabólicos, etc.) quanto locais (respiração nasal, dentição, hábitos orais). Sabe-se que a incidência de otites na infância é maior que em adultos e o que se atribui `a posição mais horizontal da tuba auditiva, em relação `a base do crânio nas crianças. A tuba auditiva é parte da orelha média que se estende desde o osso temporal até a nasofaringe, cujo desenvolvimento é influenciado pelo crescimento craniofacial. As doenças da orelha média influenciadas pela função da tuba auditiva, também ocorrem em adultos, ainda que em menor proporção. Uma vez que a menor incidência das doenças em adultos é atribuída ao crescimento da tuba auditiva, e este é dependente do crescimento craniofacial, deve haver relação entre as doenças da orelha média em adultos com as características morfológicas da face. Desse modo, o objetivo deste estudo foi correlacionar as doenças da orelha média, influenciadas pela função da tuba auditiva com a morfologia e tipologia craniofacial e determinar um traçado cefalométrico como fator prognóstico para estas doenças. Foram selecionados 66 pacientes, entre 18 e 40 anos, do Ambulatório da Divisão de Clínica Otorrinolaringológica da FMUSP. Os indivíduos foram divididos em 2 grupos sendo 32 com doença da orelha média e 34 sem, que constituiu o grupo controle. Os indivíduos não apresentavam nenhum dos fatores de exclusão a seguir: história pessoal ou familiar de fissura palatina, cirurgia bucal, maxilar, faríngea, nasal ou facial prévias, tratamento ortodôntico ou processos obstrutivos do óstio da tuba auditiva. Os pacientes foram submetidos a exame...


There are thousand types of faces and each one is unique. Individual faces are the result from the combination of different kinds of maxillas, mandibles, and orbits. The face proportions, in children, are distinct of adult ones. Craniofacial growth and development depends on a diversity of factors, such as: genetic, metabolic, nasal breathing, teeth development, etc. The auditory tube is part of middle ear and extends from temporal bone to nasopharynx. It has a more horizontal position in children than in adults; therefore otitis media is more frequent in this age group. The type of cranial base and the displacement of the maxilla during craniofacial growth influence the growth of the auditory tube. The lower frequency of otitis media in adults relates to the development of auditory tube during craniofacial growth. So, there should be a correlation between caniofacial morphology and otitis media. The aims of this study are to correlate facial types and cephalometric measurement morphology to otitis media and suggest which measurements can be used as a prediction of the evolution of otitis media. Sixty-four patients, 18 to 40 years old, were selected from the Outpatient Center of the Department of Otolaryngology of the University of São Paulo Medical School. They were divided into two groups: 32 with otitis media and 34 controls. We excluded patients with personal or familiar history of cleft palate, previous buccal, maxillar, pharyngeal, facial or nasal surgery, orthodontic treatment or obstructive process of the auditory tube ostia. All subjects underwent to complete ENT physical examination, videotoscopy, fibernasalendoscopy and lateral cephalograms. Statistical analysis of the cephalometric measurements showed significant differences of cranial base; projection of maxilla and facial height, in patients with otitis media when compared to the control group or to the ideal measures of the harmonic face...

ABSTRACT

This study included 50 normal individuals subjected to magnetic resonance imaging [MRI] study to measure Ostmann's fatty tissue [OF] dimensions in each patient to disclose its anatomical and volumetric variations in relation to Eustachian tube [ET]. The results of the individuals in whom ET was still growing were compared with the results from individuals with adult ETs. It was concluded that MRI for ET and OF is recommended in every case of otitis media with effusion without obvious etiology and in unexplained abnormal patency of ET due to weight loss

ABSTRACT

El presente trabajo es un estudio comparativo de la trompa de Eustaquio en mamíferos, aves y batracios, con la finalidad de encontrar un modelo ideal para estudios experimentales de la trompa de Eustaquio. Se describe la anatomía y fisiología de la trompa de Eustaquio en las clases y especies estudiadas, se encontró que la principal diferencia es la situación del torus tubario que varia, pudiéndose encontrar en la rinofaringe o la orofaringe según la especie. Otras diferencias que se describen, en cuanto al funcionamiento del torus tubario en mamíferos, aves y batracios, se relacionan en forma muy especial con el habitat y las circunstancias muy especiales que privan en estos animales, para facilitar la función primordial de la trompa de Eustaquio y el equilibrio de presiones intra y extratimpanicas

ABSTRACT

The purpose of this study was to describe the luminal development of the murine eustachian tube and middle ear. Thirty specimens, aging from gestational day 11 to postnatal day 21, were investigated through the light microscopic observations. The present study also used digitizer, computer, and serially sectioned temporal bone specimens for three-dimensional reconstruction to measure the volume of the eustachian tube and middle ear cavity at different gestational and postnatal ages. The first pharyngeal pouch elongated during gestational day 12 to form the tubotympanic recess. Between gestational day 13 and 14 this tubotympanic recess extended to the middle ear area. A rapid increment in the volume of the tubotympanic recess was noted between gestational day 15 and 16. At this age, a definite division of the tubotympanic recess into the eustachian tube and middle ear cavity was observed. During the postnatal period, the maximum change of the middle ear volume was noted on postnatal day 11 when the mesenchymal tissue in the middle ear cavity disappeared completely.
