Summary
Acquired medial canal fibrosis, a condition causing fibrous tissue in the ear canal, was treated with surgical excision and reconstruction. Surgical treatment for ear canal fibrosis led to hearing improvement in all patients, with minimal recurrence.
Area of Science:
- Otolaryngology
- Pathology
Background:
- Acquired medial canal fibrosis involves fibrous tissue formation in the bony external auditory meatus.
- It can arise secondary to otitis externa, suppurative otitis media, or iatrogenic causes, with some cases idiopathic.
Purpose of the Study:
- To describe the clinicopathological features and treatment outcomes of acquired medial canal fibrosis.
- To evaluate surgical management and identify complications.
Main Methods:
- Retrospective review of 14 operative procedures on 12 ears over seven years.
- Surgical technique involved excision of fibrous tissue, canaloplasty, meatoplasty, and split skin grafting.
Main Results:
- Hearing improvement was observed in all patients post-surgery after an average follow-up of two years.
- Two cases of canal cholesteatoma were noted.
- Recurrence of stenosis occurred in two ears, representing the primary complication.
Conclusions:
- Surgical intervention for acquired medial canal fibrosis can effectively restore hearing.
- While generally successful, recurrence of stenosis is a potential complication requiring monitoring.
