ABSTRACT
Chronic suppurative otitis media is chronic inflammation of the middle ear characterized by ear discharge and hearing impairment. This hearing impairment is usually due to ossicular involvement and tympanic membrane perforation. The purpose of this study is to document the pattern of ossicular damage in chronic suppurative otitis media atticoantral type Sixty patients with chronic suppurative otitis media atticoantral type were selected and admitted in ENT-I Department. Ears were examined under microscope. Mastoid exploration was done in all cases. Per-operative ossicular chain status was noted. The sequence of damage to ossicles was documented and compared with other studies. Our conclusion was that in 57[95%] patients the ossicular chain was found damaged. Whole of the ossicular chain was involved in majority of the cases 25[42%]. Incus was the most vulnerable bone and was found necrosed in 20% isolated cases and in 46% along with other ossicles

Objetivo: comparar a presença de alterações ossiculares na otite média crônica em pacientes com membrana timpânica íntegra e com tímpano perfurado. Materiais e métodos: Estudo baseado em análise hisstológica através de microscopia ótica. De um grupo e 1382 ossos temporais humanos, 144 foram escolhidos por apresentarem alterações individuais compatíveis com otite media crônica. Estes osso foram retirados de 96 indivíduos, 55 mascul., 41 fem., com idades variando entre 10 meses a 88 anos. Apenas 28 apresentavam membrana timpânica perfurada, enquianto 116 ossos temporais humanos a tinham íntegra...

10 ossicles [8 incus and 2 mallei] were removed during middle ear surgery. Also, normal ossicles were removed from reentally dead cadavers. The specimens were prepared histologically. Histopathological changes were found affecting the epithelium enveloping the ossicles with complete or partial replacement of the marrow spaces by dense fibrous tissue. Also, histopathological changes were found in the blood vessels of the bone marrow. Subsequently, it is advised not to use the autograft in ossiculoplasty
