Abstract: 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%). 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.

Abstract: birds are known to be important dispersers of plants, since the passage of seeds through the digestive tract often has a positive influence on germination percentage and speed. in this study, proportions of germination in different substrates were compared between myrsine (myrsinaceae) seeds collected manually and those ingested by birds. the guilds of birds that fed on m. umbellata and m. lancifolia were identified and comprise 24 and 12 species, respectively. a higher germination proportion was found among seeds defecated by birds and sowed in the study area. the study also found differences between the guilds of frugivores in both synchronopatric species. therefore, we suggest that m. umbellata and m. lancifolia are important food sources by birds that play a positive influence for enhance germination of myrsine.
