          Abstract

          A configuração glótica varia durante a fonação, mesmo em indivíduos sem queixas vocais e sem alterações ao exame, de acordo com a idade, o sexo, o registro vocal, a freqüência fundamental, a tensão e as lesões. Observa-se junção completa ou incompleta da borda livre da prega vocal; quando incompleta, formam-se fendas de formatos variados. OBJETIVO: Nosso objetivo é encontrar no modo de coaptação glótica, durante a fonação sustentada da vogal /épsilon/ em crianças com alteração estrutural mínima, elementos que permitam diferenciá-lo dos indivíduos com nódulo vocal ou de indivíduos sem queixas vocais. MATERIAL E MÉTODO: Estudo retrospectivo de dados de crianças atendidas no período de 1996 a 2001. A amostra constou de imagens de laringes de crianças que apresentaram diagnóstico de alteração estrutural mínima, nódulo vocal e também de crianças sem queixas vocais, estes denominados normais. Destas imagens foi analisada a configuração glótica durante a fonação da vogal /épsilon/ e realizada análise estatística para a comparação entre os três grupos. RESULTADOS: As fendas triangulares são encontradas nos três grupos, enquanto que a fenda fusiforme só ocorreu nas alterações estruturais mínimas. CONCLUSÕES: A utilização do modo de coaptação glótica em crianças, como critério diagnóstico para diferenciar alteração estrutural mínima de nódulo vocal e de laringe normal, é relevante quando se observa fenda fusiforme, condição encontrada somente nas alterações estruturais mínimas; as fendas triangulares não se mostraram significantes para diferenciar alteração estrutural mínima de nódulo vocal e laringe normal.

          The glottal closure varies during phonation, even in subjects who bears no vocal complaints and no alterations on medical examination, according to age, sex, vocal register, fundamental frequency, tension and lesions. There has been noticed complete or incomplete junction of the vocal fold free boarder; when incomplete there are formation of chinks presenting different formats. AIM: Our point is to find in the glottal coaptation mode, during sustained phonation of the vowel /epsilon/, in children having minor structural alterations, components that allow us to set them apart from subjects having vocal nodule or from subjects presenting no vocal complaints. MATERIAL AND METHOD: We have used a retrospective study of children's data assisted from 1996 to 2001, composed of children's larynx images that presented diagnosis of minor structural alterations, vocal nodule and also of children not showing any vocal complaints. From these images there has been analyzed the glottal configuration during phonation of the vowel /epsilon/ and there has been realized statistical analysis to compare the three groups. RESULTS:The triangular chinks are found in the three groups, while the spindle chink only occurred in minor structural alterations. CONCLUSION: The use of glottal coaptation mode in children as a diagnosis criterion to set the minimal structural alteration apart from the vocal nodule and regular larynx is important when we observe spindle chink, a situation found only in the minimal structural alterations. The triangular chinks were not meaningful to differentiate minimal structural alterations from vocal nodule and from regular larynx.

          Improved surgical technique for epidermoid cysts of the vocal fold.

          An improved surgical technique for epidermoid cysts of the vocal fold is presented. This technique employs a specially designed double-bladed elevator. Following betamethasone injection around the cyst, an incision is made posterior to the cyst at its mediolateral midpoint. The incision is extended anteriorly over the cyst with the use of a double-bladed elevator. The cyst then is elevated carefully from the surrounding tissue and removed. A single incision line on the upper aspect of the vocal fold should be the result. Eight patients were operated on with the present technique. The voice was improved postoperatively in all patients. The voice improvement was reflected objectively in stroboscopic findings, maximum phonation time, airflow rate, fundamental frequency and intensity of phonation, and results of acoustic analyses of voice.
