Objective:
To evaluate the clinical features of chronic stenosed otitis externa (CSOE) and its treatment.
Methods:
Fourteen patients with CSOE from 1992 to 2000 were analyzed retrospectively.
Results:
In etiologic study, otitis externa and eczema were found in nine cases, chronic suppurative otitis media in three, acetic acid burn in one, and no apparent precipitating causes in one. Ten cases were cured through single operation, 3 experienced 2 operations and one had had 3 operations. The restenosis of external auditory canal occurred in four ears.
Conclusions:
CSOE is a rare disease. Surgical treatment is the main effective method for CSOE. The important items for treatment are: removing all stenotic fibrous tissue, widening bony canal, covering all bare bone with skin, preventing wound infection and close postoperative follow-up.
