Incidence of Ossicles Erosion in Middle Ear Cholesteatoma

Abstract

Objective: To assess the incidence of ossicles erosion in chronic suppurative otitis media with
middle ear cholesteatoma.
Material and Methods: 100 patients were admitted via outpatient and emergency at the
Department of ENT Unit II , Mayo Hospital, Lahore. Patients were selected after fulfilling the
inclusion criteria. All the patients having a clinical diagnosis of chronic suppurative otitis media
underwent aural microscopic examination. After taking the informed consent surgery was
performed .During surgery the operative findings were noted in order to observe the ossicular
erosion after middle ear cholesteatoma in chronic suppurative otitis media. All the data was
analysed by SPSS version 18.
Results: The study included 100 patients having a clinical diagnosis of chronic suppurative otitis
medial with cholesteatoma Out of these 100 patients 62 (62%) were males and 38 (38%) were
females. The Mean age was 25±9 years. Radical mastoidectomy was performed in 90 patients
(90%). Modified radical mastoidectomy was done in 10 patients. (10%). Ossicles erosion was
observed in 80 patients (80%) and 20 patients (20%) had no erosion of ossicles.
Conclusion: Cholesteatoma is a commonest finding in chronic suppurative otitis media (Atico
Antral Type). A large number of patients show ossicle erosion especially the incus which leads to
conductive deafness. The intracranial and extra cranial complications of cholesteatoma can be
prevented by early diagnosis and surgery. The aim of surgery is to eradicate the disease and
provide safe and dry ear.
