title: Long-term results with operated sinus tympani retraction cholesteatoma.
abstract: OBJECTIVE
  Utilizing an endaural approach, we described the surgical treatment of 29 cases of sinus tympani retraction cholesteatoma in 1996. The purpose of this paper is to provide long-term results in this group of patients.
  
  
  METHODS
  A retrospective chart analysis of 29 previously reported patients was undertaken in an effort to identify hearing results and the risk of cholesteatoma recurrence following sinus tympani retraction surgery.
  
  
  RESULTS
  The follow-up period ranged from 9 to 16 years (mean of 13.2 years). Speech discrimination (SD) and conductive hearing (CH) decline occurred in 23 of 28 patients, but only on the average of 5.6% and 9 dB throughout the speech frequencies, respectively. Speech discrimination and conductive hearing improved in 5 of 28 patients; one patient was lost to follow-up. One patient developed a recurrent cholesteatoma requiring a canal wall-down mastoidectomy.
  
  
  CONCLUSIONS
  The endaural approach for sinus tympani cholesteatoma provided stable hearing in most of the patients in this series. One cholesteatoma recurrence required conversion to a canal wall-down mastoidectomy. This developed in a noncompliant patient, whose pars tensa retraction deepened as a result of failure to have his ventilation tube replaced. Semiannual office visits are recommended in patients who undergo this otologic approach for sinus tympani cholesteatoma.
