Abstract
Objective: To determine subjective outcomes after cholesteatoma surgery.
 Design: Cross sectional observational study
 Methods: Study place: Shaheed Ziaur Rahman Medical college Hospital (SZMCH), Bogura, Bangladesh
 Study population: Chronic otitis media (COM) with extensive cholesteatoma. Interventions: Canal wall down mastoidectomy for cholesteatoma.
 Main Outcome Measures: In this study, the Chronic Ear Survey (CES) was provided to all patients preoperatively and one year after surgery. The preoperative and postoperative score differences were analyzed. We also assessed correlations between chronic ear survey scores and air conduction threshold.
 Results: Seventy six patients were enrolled in our study & marked improvements were found in total CES score & all subscale scores postoperatively (P value: 0.00). The total CES score and symptom subscale scores were observed greater improvement (P value: 0.00).Significant negative linear correlations were observed among total CES scores, symptom subscale scores and air conduction thresholds (P<.05).
 Conclusion: The present study suggests that canal wall down mastoidectomy (CWDM) provides a significant improvement in the post-operative Quality of life (QoL) &b there is a significant association between subjective outcomes &the objective audiometric results.

Highlights
IntroductionThe aims for surgery are to eradicate the infection, to make well epithelialized, self-cleaning ear, to reconstruct hearing mechanism and to improve quality of life (QoL)
Cholesteatoma surgery is one of the most controversial topics in otology
Number of modifications has been introduced in canal wall down mastoidectomy (CWDM) in order to overcome some of its drawbacks while maintaining its best outcome
Summary
The aims for surgery are to eradicate the infection, to make well epithelialized, self-cleaning ear, to reconstruct hearing mechanism and to improve quality of life (QoL). The aim of cholesteatoma surgery is not to remove disease in order to create a safe ear. CWDM is an established surgical technique in the management of cholesteatoma. Number of modifications has been introduced in CWDM in order to overcome some of its drawbacks while maintaining its best outcome. Advantages of CWDM are complete removal of the disease, easy inspection of the hidden area of cholesteatoma, less formation of the new retraction pockets, early detection of recurrence of disease and improved postsurgical outcome[1]. The expectations of hearing gain after surgery is minimal but a successful tympanoplasty or ossiculoplasty can reconstruct the mechanism hearing and improve hearing status
