Abstract
Introduction: Cholesteatoma surgery remains a topic of ongoing debate in the medical literature. The optimal objectives of cholesteatoma surgery should aim for the complete eradication of the disease and the maintenance of optimal hearing function, ideally achieved through a single-stage surgical intervention whenever feasible. The primary objective of this investigation was to assess the auditory outcomes of ossiculoplasty within canal wall down tympanoplasty during single-stage middle-ear cholesteatoma surgery. Methods: We conducted a retrospective analysis of a consecutive cohort comprising 178 cases that had undergone canal wall down tympanoplasty with ossicular reconstruction due to chronic otitis media complicated by cholesteatoma. Cholesteatomas were surgically managed in a single-stage procedure under general anesthesia using a retroauricular approach. The surgical process involved removal of cholesteatomas from the outer ear canal, followed by atticotomy, antrotomy, and mastoidectomy with canal wall down tympanoplasty. Results: Preoperative audiometric assessments indicated an average air conduction pure tone average (PTA) of 48.42 dB and an average bone conduction PTA of 21.03 dB. Postoperatively, the mean air conduction PTA was 36.65 dB, while the bone conduction PTA averaged 23.09 dB. The average pre- and postoperative air–bone gaps (ABGs) were 29.28 dB and 13.24 dB, respectively, resulting in a gain of 16.04 dB. Notably, approximately 70% of patients achieved ABG closure within 20 dB. Conclusion: Our study suggests that cartilage placed above the prosthesis between stapes or stapes footplate in canal wall down mastoidectomy may improve Hearing. Failures may result from insufficient footplate-prosthesis contact or progressive fibrosis in the middle-ear space. Nonetheless, our positive functional outcomes highlight the significance of reconstructing the ossicular chain in these procedures. We recommend further clinical investigations to optimize hearing outcomes in canal wall down tympanoplasty.
