J Uni Med Dent Coll Jan ;2(1):28-33.

Introduction: Oto-endoscopy is a new and latest introduction in the middle ear and mastoid surgery. Its application has not yet gained popularity in Pakistan and our study is first of its kind in Pakistan to evaluate the utility of oto-endoscope in canal wall down procedures. Objectives: Oto-endoscopic evaluation after radical and modified radical mastoidectomy for residual disease. Rationale: To see whether the use of oto-endoscope helps in decision making to modify the procedure per-operatively or decrease the incidence of residual disease better than microscope in radical and modified radical mastoidectomy. Study design: Case series Setting: ENT Unit, Madina Teaching Hospital, Faisalabad ( a tertiary care hospital). Subjects: (sample, sampling technique): Non-probability convenience sampling. Twenty patients in total Intervention: radical and modified radical mastoidectomy Methods (Main outcome measures): To assess presence of residual cholesteatoma with oto-endoscope in three most common sites notorious for residual cholesteatoma after radical and modified radical mastoidectomy is completed under microscope Results: Oto-endoscopy detected five cases of residual disease after modified radical mastoidectomy and one case after radical mastoidectomy Conclusions: 1.Oto-endoscopy does influence the detection of residual cholesteatoma in sinus tympani, anterior epitympanum and protympanum 2. It can also modify the decision to convert modified radical to radical mastoidectomy if required Keywords: cholesteatoma, residual disease, oto- endoscopy.
