ABSTRACT

Background: Cholesteotoma is a benign but destructive lesion leading to ossicular necrosis.

Objective: To see the frequency of incus bone erosion on mastoid exploration in chronic suppurative otitis media with middle ear cholesteotoma.

Study Design: Cross-sectional descriptive study.

Setting: This study was carried out in the Department of ENT Unit-2, Sir Ganga Ram Hospital, Lahore.

Duration of Study: Fifteen months months (10th April, 2019 to 9th July, 2020)

Sample technique: Non- probability purposive sampling

Methods: One hundred and twenty patients were admitted through outpatient department of ENT Unit-2, Sir Ganga Ram Hospital Lahore. Patients were included after fulfilling the inclusion criteria and information was collected on a prescribed proforma. Finally during surgery under general anesthesia, the operative findings were noted to know the incus bone erosion after middle ear cholesteatoma formation in chronic suppurative otitis media.

Results: A total number of one hundred and twenty patients of chronic suppurative otitis media with middle ear cholesteatoma were included. Out of which 80 (66.7%) were males and 40 (33.3%) were females(Table 1).The patients shown in table 2 were divided in six age groups (Table 2).Table 3 shows that the procedure of mastoidectomy was performed in 112 patients (93.3%) and modified radial mastoidectomy was performed in 8 patients (6.7%).Incus bone erosion in chronic suppurative otitis media with middle ear cholesteatoma in 102 patients (85%) and 18 patients (15%) have no incus bone erosion (Table 4).

Conclusion: Ear discharge was the most common presenting characteristic of chronic suppurative otitis media with cholesteatoma. The majority of the cases had ossicular erosion, with the incus being the most common site of involvement. Males are more likely than females to develop cholesteatoma.
