findings in infants with cleft lip and palate Summary

Tympanometry 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%).
