Abstract
The clinical data of 47 children (52 ears) with middle ear cholesteatoma at Eye & ENT Hospital, Fudan University from January 2021 to February 2024 were prospectively collected. There were 30 males and 17 females, with a mean age of (8.5±2.8) years. Surgical procedures included endoscopic tympanoplasty (29 ears), combined endoscopic/microscopic tympanoplasty (8 ears) and microscopic tympanoplasty (15 ears). After endoscopic surgeries, the mean air conduction hearing threshold, mean bone conduction hearing threshold and air bone gap were (28.4±10.4) dB HL, (12.4±5.9) dB HL and (16.0±6.3) dB HL, respectively, which were significantly improved compared with preoperative indicators [(40.2±14.0) dB HL, (16.3±6.8) dB HL and (23.9±9.8) dB HL, respectively] (all P<0.05). There were statistically significant differences in the postoperative mean air conduction hearing threshold and air bone gap among three surgical groups, and the value of endoscope group was lower than those of microscope group and endoscope combined with microscope group (all P<0.05). After a follow-up of 5.6 (1.2, 11.5) months, no statistically significant differences were observed in the rate of successful tympanic membrane healing between endoscope group and microscope group (P=0.747). One ear in the endoscope group experienced recurrence three years after surgery, and no intracranial and extracranial complications occurred. The current study indicates that endoscopic surgery for pediatric cholesteatoma improves hearing with good results.
