Abstract

Background: Otosclerosis with obliterated footplate describes a condition with an overgrowth of bone so that the oval window is almost indistinguishable from the surrounding area. The occurence of round window obliteration is uncommon. In such cases, surgery is more difficult to perform and the results are often unsatisfactory. Purpose: To find out the management option for obliterative otosclerosis. Case report: A 35-year-old-man with suspected bilateral otosclerosis. The patient underwent transcanal endoscopic stapes surgery of the left ear with large fenestra stapedotomy procedure. Clinical question: In adult patients with obliterative otosclerosis, does stapes surgery improve hearing function and reduce complication? Review method: Using PubMed, EBSCOhost, Scopus and Proquest to search for the evidence of randomised control trial (RCT), cohort and case-control studies. Critical appraisal was conducted using critical appraisal tools from Center for Evidence Based Medicine (CEBM), Oxford University and qFAITH for systematic review/meta-analysis. Result: The literature searching used eligibility criteria based on keywords from clinical question found one study regarding the evaluation of intra-operative factors in otoslecrosis surgery outcomes, which was relevant to our clinical question. Conclusion: Large fenestra stapedotomy or stapedectomy is the preferred surgical technique for the management of obliterative otosclerosis. The involvement of round window caused a sensorineural hearing loss (SNHL) component and has a worse prognosis of hearing outcome post operatively. A further study is required to assess the best management for obliterative otosclerosis.
