OBJECTIVE: To investigate the recidivism rate of cholesteatoma treated via endoscopic ear surgery (EES), either via transcanal endoscopic ear surgery or endoscopic assisted tympanomastoidectomy compared with a microscopic postauricular approach. STUDY DESIGN: Retrospective chart review. SETTING: Academic otology practice. PATIENTS: Adult patients (18 years and older) with at least 11 months of surgical follow-up who were treated for cholesteatoma via endoscopic techniques or microscopic postauricular approach. INTERVENTION: Use of the endoscope for cholesteatoma dissection. MAIN OUTCOME MEASURE: Residual or recurrent cholesteatoma identified at second look surgery or postoperative diffusion-weighted magnetic resonance imaging. RESULTS: Fifty-nine patients treated for cholesteatoma via endoscopic techniques and 35 patients treated via microscopic postauricular approach were analyzed. The endoscopic group required significantly fewer mastoid procedures (28% versus 80%, p-value 0.001). Postoperative changes in median ABG (5 dB versus 3.75 dB, p = 0.9519), median PTA (6.875 dB versus 1.25 dB, p = 0.3864), and median word recognition score (0% versus 0%, p = 0.3302) were not significantly different between the EES and microscopic surgery groups. Median operative times were not significantly different between the two groups (182 min endoscopic versus 174 min microscopic, p-value 0.66). The rate of residual disease (17% EES versus 17% microscopic, p = 0.959) or disease recurrence (18% endoscopic versus 20% microscopic, p = 0.816) were not significantly different between the two groups. CONCLUSIONS: EES is an effective option for cholesteatoma management with similar rates of recurrent or residual disease as compared with the more traditional microscopic postauricular approach in these samples.
