[The clinical application of endoscope holder in revision tympanoplasty surgery].

The current study summarized the surgical key points and technique advantages of endoscope holder in revision tympanoplasty. Fifteen patients who underwent revision tympanoplasty using the endoscope holder between January 2023 and April 2024 at the Department of Otorhinolaryngology, Peking Union Medical College Hospital were retrospectively collected. There were 6 males and 9 females, with an average age of (37.1±13.4) years. All patients successfully completed the revision tympanoplasty under the endoscope holder. The median follow-up time was 8 months (range: 2-16 months). Postoperative otoendoscopic examinations within 2-3 weeks revealed that all patients had dry ears, with well-healed ear canal flaps and tympanic membranes. Pure tone audiometry demonstrated significant improvements in pure tone air conduction thresholds [preoperative level: (54.3±18.0) dB HL; postoperative level: (37.4±18.4) dB HL; <i>P</i>=0.002]. The air-bone gap (ABG) decreased from (36.7±13.9) dB HL to (22.3±13.1) dB HL after surgery, indicating a marked improvement (<i>P</i>=0.003). The current study suggests that the endoscope holder technique has good application effects in revision tympanoplasty.
