Short-Term Hearing Prognosis of Ossiculoplasty in Pars Flaccida Cholesteatoma Using the EAONO/JOS Staging System
2019
Overview
OBJECTIVES: The aim of the present study was to investigate the prognostic factors for short-term hearing outcomes of ossiculoplasty for primary pars flaccida cholesteatoma according to the European Academy of Otology and Neurotology/Japanese Otological Society (EAONO/JOS) and 2015 JOS staging systems. MATERIALS and METHODS: A total of 34 patients with primary pars flaccida cholesteatoma who underwent one-stage tympanomastoidectomy with partial ossicular reconstruction using double cartilage block were included in the study. The postoperative pure-tone average air-bone gap (PTA-ABG) was calculated, and two criteria of successful hearing outcomes were defined as [less than or equal to]10 and [less than or equal to]20 dB. Patients were classified according to the EAONO/JOS and 2015 JOS staging systems. Cochran-Armitage test was used to statistically analyze staging, and Fisher's exact test was used to analyze other factors. RESULTS: Successful hearing outcome with postoperative PTA-ABG [less than or equal to]10 and [less than or equal to]20 dB occurred in 23.5% and 55.9% of cases, respectively. When postoperative PTA-ABG [less than or equal to]20 dB was defined as successful, the success rate significantly decreased with increase in EAONO/JOS stage, and S0 pathological status of the stapes (no involvement) was a significantly favorable predictive factor. When postoperative PTA-ABG [less than or equal to]10 dB was regarded as successful, the significantly favorable predictive factors were S0 pathological status of the stapes and development of mastoid cells with MC2-3 (better developed cells). CONCLUSION: Favorable prognostic factors for hearing outcomes of tympanomastoidectomy with partial ossicular reconstruction for primary pars flaccida cholesteatoma were low stage following the EAONO/JOS staging system and no stapes involvement and better development of mastoid cells following the 2015 JOS staging system.
