Long-term outcome data on blind sac closure during subtotal petrosectomy may inform surgical planning, but specific results are not available from the provided description; await full-text review before changing surgical practice.
Long-term follow-up data on blind sac closure fills a gap in the evidence base for a technically demanding but consequential step in skull-base and middle ear surgery.
- 01Blind sac closure seals the external auditory canal during subtotal petrosectomy.
- 02The study focuses on long-term outcomes, addressing a gap in follow-up data.
- 03Indications include middle ear and skull-base diseases.
- 04Outcomes likely include wound healing, cholesteatoma recurrence, and cavity problems.
