Ossicular changes in chronic suppurative otitis media, atticoantral disease

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
