Abstract

PURPOSE:

This study evaluated the feasibility of endoscopy in exposing the anterior surface of the malleus and tensor tympani tendon (ASMT) in children with congenital cholesteatoma (CC), and investigated the outcomes of hearing, postoperative complications, and residual or recurrent disease in endoscopic surgical approach cases.

METHODS:

A retrospective case review was performed in one tertiary referral center. Twelve children with CC involving the ASMT were recruited, and their medical records were reviewed. All patients underwent either total endoscopic surgery (n = 3) or endoscope-assisted surgery (n = 9), and Potsic staging was adopted to classify CC according to its severity: stage I (n = 8), stage II (n = 2), and stage III (n = 2). The mean follow-up period was 15.5 ± 2.8 months. The visibility of the ASMT by endoscope assistance, audiological results, surgical and postoperative complications, and recidivism of CC were analyzed.

RESULTS:

The ASMT was well visualized by endoscope assistance in all cases. No patient showed hearing deterioration at 3 months after surgery, and none experienced residual or recurrent disease during the follow-up period. Postoperative complications were not observed.

CONCLUSIONS:

Total endoscopic or endoscope-assisted surgery could help surgeons directly visualize the ASMT in children, with negligible risks of hearing deterioration, postoperative complications, and recurrent disease. Our study might suggest that endoscopic ear surgery should be considered in patients with CC in the ASMT.
