Summary
Mastoid obliteration using postconchal soft tissue and postauricular pericranial flaps is reliable, resulting in healthy, dry cavities. Minor flap shrinkage may occur but does not impede cavity management.
Area of Science:
- Otolaryngology
- Surgical Techniques
- Reconstructive Surgery
Background:
- Canal wall-down mastoidectomy can lead to complications like cavity problems.
- Mastoid obliteration aims to create a safe and manageable post-operative cavity.
Purpose of the Study:
- To describe the technique of mastoid obliteration using specific soft tissue flaps.
- To evaluate the outcomes and reliability of this obliteration method.
Main Methods:
- Retrospective review of 15 patients undergoing mastoid obliteration post-canal wall-down mastoidectomy.
- Utilized postconchal soft tissue and postauricular pericranial flaps.
Main Results:
- 15 patients achieved dry cavities within 6-8 weeks, except one with keratin accumulation.
- Five patients (33%) experienced distal flap atrophy, creating small pockets at the attic and aditus after 6 months.
Conclusions:
- Postconchal soft tissue and postauricular pericranial flaps are dependable for mastoid obliteration.
- The obliteration technique yields a round, dry, and healthy cavity suitable for follow-up.
- Expect some distal flap shrinkage after 6 months, but it remains a reliable method.
