The purpose of this operation is to reinspect the ear spaces for disease and to improve the hearing. Surgery may be performed through the ear canal or from behind the ear, under a local or general anesthesia. Sound transmission to the inner ear is accomplished by replacing missing ear bones. Surgery is usually done as an out-patient. The patient may be hospitalized for one night and may return to work in four to seven days.
Healing is usually complete in eight weeks.
Hearing improvement is frequently noted at that time. The purpose of this operation is to eliminate discharge from a previously created mastoid cavity defect and to improve the hearing. The operation is performed under general anesthesia through an incision behind the ear. At times, the ear canal is rebuilt with cartilage or bone. The eardrum is repaired and, if possible, the hearing mechanism is restored.
