- ItemAcesso aberto (Open Access)Análise dos padrões histopatológicos do colesteatoma adquirido da orelha média(ABORL-CCF Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial, 2008-12-01) Alves, Adriana Leal; Pereira, Celina Siqueira Barbosa; Ribeiro, Fernando De Andrade Quintanilha [UNIFESP]; Fregnani, Jose Humberto Tavares Guerreiro; SCSP FCM Depto. Morfologia; Universidade Federal de São Paulo (UNIFESP); SCSP FCM Depto. de Otorrinolaringologia; Fundação Antônio PrudenteMiddle ear cholesteatomas are characterized by the presence of stratified squamous epithelium in this cavity with highly invasive properties causing bone destruction and it may lead to complications. AIM: To study the histopathological features in acquired cholesteatomas of the middle ear, correlating this data with patient age. Study design:clinical and experimental cross-sectional study. MATERIAL AND METHODS: Samples were obtained from 50 patients submitted to otologic surgery for the removal of middle ear cholesteatomas from 2006 to 2007. Thirty four patients were adults and 16 were children. Samples were studied by histological analysis. RESULTS: we found the presence of epithelial atrophy (78%), epithelial acanthosis (88%), hyperplasia of the basal layer (88%) and formation of epithelial cones (62%). There was a positive and significant correlation between histopathological variables (such as epithelial acanthosis, hyperplasia of the basal layer and formation of epithelial cones). Histopathological variables presented no statistical significant difference in both age groups (p>0,05). CONCLUSION: Cholesteatomas have hyperproliferating characteristics with epithelial acanthosis, hyperplasia of the basal layer and the presence of epithelial cones in the matrix.
- ItemAcesso aberto (Open Access)Influência do tipo de amamentação nas condições de orelha média de lactentes(Associação Brasileira de Otorrinolaringologia e Cirurgia Cervicofacial, 2012-02-01) Garcia, Michele Vargas [UNIFESP]; Azevedo, Marisa Frasson de [UNIFESP]; Testa, Jose Ricardo Gurgel [UNIFESP]; Luiz, Cyntia Barbosa Laureano [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)Infants should be submitted to hearing screening upon birth, and for the results to be complete, it is necessary to assess middle ear conditions. OBJECTIVE: To check whether the type of breastfeeding in infants between zero and four months can impact middle ear conditions my means an ENT assessment and acoustic immittance comparing neonates who were submitted to hearing screening with those who failed it. Materials and METHODS: Otoacoustic emissions (OAE) was carried out in 60 infants between zero and four months. They were distributed in two groups; group I had the infants with OAE and those infants in group II did not have OAE. They were submitted to tympanometry with a 1000 Hz test tone and ENT assessment. RESULTS: Bottle fed infants or those who were fed in a mixed way had more changes to their audiometry and ENT assessment, with a statistically significant difference. The breastfed infants had a higher occasion of normal tympanometries and normal otorhinolaryngological assessment, with statistically significant difference. CONCLUSION: We then concluded that those breastfed implants had less ENT changes and as well as less acoustic immittance change, thus enabling OAEs. Breastfeeding alone can be considered a protection factor against middle ear changes.
