Achados otoscópicos e timpanométricos em lactentes com fissura labiopalatina

Abstract

Tympanomet ry plays a fundamental role in the identification of middle ear alterations, which are frequent in the population with cleft lip and palate. Aim: do a retrospective analysis of the otoscopy and tympanometric exams of infants with cleft lip and palate who were not operated. Retrospective study. Materials and Methods: we analyzed 273 charts from infants with cleft lip and palate whom, from March 1996 to April of 2002 underwent pneumatic otoscopy and tympanometry with a 226 Hz probe. Results: We did not find statistical significance in the otoscopic and tympanometric findings considering ears and genders. We observed 84% of alterations in otoscopy (opacification/83.4%, visible fluid in the middle ear /1.5%, the ear drum does not move during inflation /1.8 and retraction/0.7) and 65% in tympanometric curves (B/38%), A/36.5%, As/21%, C/4% and Ad/0.5%). Conclusion: female and male infants with cleft lip and palate did not differ as far as otoscopic and tympanometry findings are concerned. All types of tympanometric curves were present, and types A and B were the most frequent ones. Ear drum opacification was the most frequent otoscopic finding. Pneumatic otoscopy identified a larger number of alterations when compared to conventional tympanometry.

Audição de crianças com fissura labiopalatina e baixo peso: estudo comparativo

“…Regarding the immittanciometry all types of tympanometric curves were presente for the three groups studied, with 58% (78 ears) of tympanograms A classified as normal, once this type reveals normal functioning of the tympano-ossicular system. Studies (24,28,29) confirm this finding.…”

Timpanometria em lactentes com fissura labiopalatina utilizando sonda de multifrequência

“…Além de que o uso do tom sonda de baixa frequência permite é permitir um nível de tom sonda mais alto sem elicitar um reflexo acústico (Fowler e Shanks, 2002 Margolis, 2003, Feniman et al, 2008. Esse fato tem conduzido pesquisadores (Carvallo, 1992;McKinley at al, 1997;Sutton et al, 2002;Kei et al, 2003, Garcia, Azevedo e Testa, 2009) a investigar o uso de sonda de alta frequência (678 ou 1000 Hz) em lactentes, na busca por resultados mais confiáveis.…”

Processamento auditivo em crianças com fissura labiopalatina com e sem história de otite

“…Several studies (10,11,21,27) have emphasized peripheral hearing in the population with CP, being largely known to its high incidence of alterations in the middle ear, due to a faulty velotubal aeration mechanism . Thus, the media otitis and hearing losses of conductive type, usually bilateral, have figured as the most important pathologies in this population.…”
