| Popis: | Objectives The main goal of the present study was to assess hearing outcome for malleus removal in cholesteatoma surgery compared to a group with malleus conservation. The secondary aim was to compare the auditory involvement of the stapes between the two groups. Material and methods A single-center observational study included adult patients operated on by ossiculoplasty for acquired cholesteatoma between 2015 and 2019. Endpoints comprised improvement in pure-tone average air-bone gap (PTA-ABG) and air-bone gap (ABG) at conversational frequencies and, independently, per frequency. 136 patients were included: 95 with conserved malleus (M+) and 41 with malleus removal (M(). Mean time to audiometric follow-up was 9 months in both groups. Results The PTA-ABG improvement was 4.4 ± 12.6 dB for the M+ group and 3.8 ± 13.4 dB for the M− group, with no significant significance (P = 0.8). Better results (not exceeding 7.5 dB) were found for the M+ group at 2 and 8 kHz (P = 0.3 and P = 0.052 respectively). Presence or absence of the stapes did not affect the results in either group. Conclusion Those results suggest a negligible role of the malleus in early hearing outcome of tympanoplasty for cholesteatoma. A slight improvement was observed in the M+ group at 2 and 8 kHz, but its interpretation remains uncertain. |
