Abstract

Objective

To investigate the efficiency of additional intraoperative endoscopic inspection in reducing residual cholesteatoma in pediatric cholesteatoma involving the mastoid treated with classic canal-wall-up mastoidectomy and tympanoplasty.

Materials and methods

32 cases of pediatric cholesteatoma involving the mastoid were enrolled in this perspective study and treated with classic canal-wall-up mastoidectomy and tympanoplasty. Transmastoid posterior tympanotomy, atticotomy and transecting tendon of tympani tensor were conducted to achieve adequate visualization of hidden spaces in the middle ear. After complete removal of cholesteatoma, endoscopic inspection was additionally performed to check residual cholesteatoma. All cases had at least a 2-year follow-up by routine otoscopy examination, CT scan or MR imaging. Residual rates of both intraoperative and follow-up findings were used to evaluate the efficiency of the endoscopic inspection in reducing residual cholesteatoma and compared with published reports.

Results

The additional intraoperative endoscopic inspection did not find any residual in this case series. In the 2-year follow-up, 2 cases (2/32, 6.3%) with residual cholesteatoma and 3 cases with recurrence (3/32, 9.4%) were found. The mean duration of endoscopic inspection and microscopic procedure were 17.9 min and 93.6 min, respectively.

Conclusions

This study suggested that the additional intraoperative endoscopic inspection in microscopic CWU surgery for pediatric cholesteatoma involving the mastoid had no obvious value in reducing residual cholesteatoma but took extra time.
