[Causes and management strategies for unplanned reoperation after endoscopic middle ear surgery].

The clinical data of 24 patients (25 ears) aged (42.4±13.5) years who underwent unplanned reoperation in the Affiliated People's Hospital of Fujian University of Traditional Chinese Medicine between January 2018 and May 2025 were retrospectively analyzed, including 12 males and 12 females. The main reasons for the reoperation were tympanic adhesion/granulation hyperplasia (68.0%, 17/25), displacement/dislocation of artificial ossicles (32.0%, 8/25), reperforation of tympanic membrane (32.0%, 8/25), and recurrence of cholesteatoma (28.0%, 7/25). The air-bone conductance differences at each frequency were significantly reduced after the reoperation (P<0.001). The reoperation rate can be reduced by preserving the normal tympanic membrane mucosa, using anti-adhesion materials, repairing the tympanic membrane with the sandwich method, implanting the complete type artificial ossicle with the Ω-shaped base plate, and thoroughly removing the cholesteatoma epithelium, and other preventive and therapeutic strategies.
