To Evaluate The Results Of Complete Exenteration Of Mastoid Air Cell Tracts Underlying Cholesteatoma With Canal Wall Down Mastoidectomy

ABSTRACT

Chronic Suppurative Otitis Media(CSOM) is long standing infection of mucoperiosteal lining of middle ear cleft. CSOM is classified into Tubotympanic or Safe and Atticoantral or Unsafe type. Atticoantral type involves the pars flaccida and is characterized by formation of a retraction pocket in which keratin accumulates to produce cholesteatoma. Mainstay of the management of atticoantral disease is surgery of mastoid and middle ear. Majority of otolaryngologists find the Canal wall down , open cavity operation with wide access to be the safest and simplest means of managing middle ear cholesteatoma. In present study , results of complete exenteration of mastoid air cell tracts underlying cholesteatoma with canal wall down mastoidectomy are studied.
