Medical management may be employed initially in select cases of soft tissue stenosis. Surgery is an option for cases that fail medical management.
For both bony and soft tissue stenosis, surgical treatment is recommended when the patient develops chronic/recurrent external otitis or conductive hearing loss. Another indication for surgery is difficulty fitting a hearing aid.
Oncologic procedures are necessary when benign or malignant tumors cause canal obstruction. A description of these types of procedures is beyond the scope of this chapter.
