Managing Complex Chronic Otitis Media: Insights from Subtotal Petrosectomy with Blind Sac Closure

Area of Science:

• Otolaryngology
• Surgical Innovation

Background:

• Chronic otitis media presents significant surgical challenges.
• Subtotal petrosectomy is a complex, often last-resort intervention for refractory cases.

Purpose of the Study:

• To evaluate the efficacy and safety of subtotal petrosectomy with blind sac closure of the external auditory canal.
• To review existing literature on this surgical technique for chronic and recurrent otitis media.

Main Methods:

• Retrospective analysis of nine patients undergoing the procedure.
• Systematic literature review following PRISMA guidelines, analyzing 17 selected studies.

Main Results:

• The patient cohort included eight cases of chronic cholesteatomatous otitis media and one atelectatic case.
• No postoperative complications were reported in the retrospective analysis.
• Literature review synthesized SP applications, techniques, and outcomes from diverse studies.

Conclusions:

• Subtotal petrosectomy with blind sac closure is an effective management strategy for chronic otitis media.
• The procedure demonstrates a favorable safety profile with improved postoperative results.
• This study provides valuable insights into the application and success of subtotal petrosectomy, enhanced by a comprehensive literature review.
