Re-operation after failure of surgery for chronic ears

Introduction Re-operation on chronic ears is associated with particular problems. Scar tissue, fibrous tissue and adhesions in the tympanum make dissection during re-operation difficult. The sigmoid sinus, dura and facial nerve may have been exposed at the initial operation. Re-operation for post-operative cholesteatoma, especially residual and recurrent cholesteatoma following surgery in which a cavity obliteration technique has been used, is often troublesome and may present the surgeon with unexpected problems. The object of the present study was to evaluate the reasons for failure of surgery for chronic ears, the findings at re-operation and the results of re-operation.
