“…Removal of any visible cholesteatoma. A routine thorough review of all middle ear compartments is performed, as recommended by Costa et al 5 Careful observation of the main structures of the middle ear, such as the protympanum, eustachian tube, supratubary recess, anterior and posterior epitympanum, facial recess, oval and round window niche, and hypotympanum was performed. In the mastoid region, the aditus, antrum, and tip were also examined.…”

Introduction The treatment of cholesteatoma is generally surgical, and the major obstacle is the high prevalence of recidivism. The endoscopic ear surgery technique is proposed to minimize this problem. Objectives To utilize endoscopes to visualize and manipulate cholesteatoma residues after microscopic removal Methods Cross-sectional study. Thirty-two patients with cholesteatoma underwent microscopic wall-up mastoidectomy combined with the endoscopic approach. The subjects were assessed for the presence and location of covert disease. Results Of the 32 cases, 17 (53.12%) had residual cholesteatoma in the endoscopic phase. Minimal disease was found, usually fragments of the cholesteatoma matrix. Pars tensa cholesteatomas had more covert disease than pars flaccida cholesteatomas (62.50% vs 43.75%). Posterior recesses (47.05%) and tegmen tympani (41.17%) were the locations with more covert disease (p < 0.05). Conclusion Cholesteatomas of the pars tensa presented more residual disease and were significantly more common in the posterior recesses and tegmen tympani.

This study aimed to determine the effectiveness of using endoscopes in reducing recidivism secondary to residual cholesteatoma after canal wall-up tympanomastoidectomy. Study Design: Randomized clinical trial. Setting: Tertiary referral center. Patients: Patients with cholesteatoma, aged 7 to 70 years. Interventions: Subjects were randomly allocated into two groups: endoscopic-assisted canal wall-up (EACWU; group 1) and conventional canal wall-up (CWU; group 2) techniques. Pars flaccida and pars tensa subgroups were analyzed according to the anatomic location of cholesteatoma origin. Main Outcome Measures: Presence or absence of residual cholesteatoma, based on second look surgery, diffusion-weighted magnetic resonance imaging, or video-otoscopy at 12 and 18 months after surgery. Results: In total, 57 ears were analyzed: 29 in group 1 and 28 in group 2. Group 1 revealed residual disease in 17.2% of ears, whereas group 2 had residual disease in 35.7% (p > 0.05) of the ears. In the pars tensa cholesteatoma subgroup, the incidence of residual disease was 13.3% for EACWU and 47.1% for the CWU technique (p < 0.05). A tendency of reduced incidence was observed for cholesteatoma due to residual disease using EACWU. In addition, a statistically significant reduction in the residual disease was observed in the subgroup of pars tensa cholesteatomas. In this subgroup, the relative risk was 0.28, and the number needed to treat was 4.6. Conclusion:The use of the endoscope reduces the incidence of recidivism secondary to residual disease in pars tensa cholesteatomas. Endoscopic-assisted surgery may be useful in cases with an indication for canal wall-up tympanomastoidectomy. Level of Evidence: 1b.
