Predictors of recurrent pathology and prognosis of the results of surgical treatment of patients with acquired middle-ear cholesteatoma

This study aims to test the effectiveness and safety of exteriorization surgery comprising atticotomy and obliteration of the additus ad antrum, also referred to as attic exposition–antrum exclusion (AE-AE) surgery. This surgery combines otoendoscopy with surgical microscopy for the treatment of acquired pars flaccida cholesteatoma in stages Ib and II (according to the classification of the Japan Otological Society) present in the attic and the tympanic cavity. We reviewed a historical cohort of 65 patients. Of the total, 21 were treated with canal wall-up tympanomastoidectomy (CWU). Patients in whom the AE-AE technique was performed had residual and recurrence rates of 0% and 9.1%, respectively, compared with 28.6% and 9.5%, respectively, for those treated with CWU. In the AE-AE procedure, surgery is performed in one stage compared with the two stages in CWU, to address the risk of residual cholesteatoma. Auditory thresholds were higher in the CWU group compared with the AE-AE group in the pre-surgery (53 ± 16 vs. 44 ± 15 dB; p = 0.039) and post-surgery (52 ± 18 vs. 42 ± 16 dB; p = 0.042) evaluations but not in pre–post-surgery comparisons for either the AE-AE technique (p = 0.89) or the CWU technique (p = 0.96). We conclude that AE-AE is an effective and safe technique for the treatment of acquired stage Ib and II cholesteatoma present in the attic and tympanic cavities.
