Abstract
Objectives: To explore the risk factors of early postoperative taste disturbance (EPTD) after type I endoscopic tympanoplasty and operative modification strategies to improve taste disturbance. Methods: This was a controlled study. One hundred and twenty-four patients who underwent type I endoscopic tympanoplasty with tragal cartilage graft were separated evenly into control and modified groups. The full-thickness tragus cartilage graft was placed close to the bony annulus to ensure drum integrity in the control group, and in the modified group, the cartilage graft was not in contact with the posterior-superior bony annulus, and the inferior-posterior of the scutum. Univariate and multivariate models were used to analyze the possible factors affecting EPTD and the prognosis of taste recovery. Results: The incidence of EPTD was significantly lower in the modification group (24.19%) than in the control group (56.45%) (OR: 4.24, 95% CI: 1.93-9.33, P < .001). Surgical manipulation of the chorda tympani nerve resulted in a higher incidence of EPTD (OR: 2.43; 95% CI: 1.06-5.57, P = .035). The size of the graft did not affect taste disturbance. No difference in the taste recovery rate was observed between the control and test groups (Z = -1.57, P = .116) after 3 months. The recovery rate of patients with manipulated chorda tympani nerves was still lower than that of patients without at 3 months (Z = -2.74, P = .006). Conclusion: Modified surgery and reduced manipulation of the chorda tympani nerve effectively reduce EPTD. Manipulated chorda tympani nerves may have a persistent effect on taste recovery.
