Objective: To investigate the feasibility of bilateral same-day myringoplasty and the indications for myringoplasty for patients with bilateral tympanic membrane perforation, and to summarize relevant experience.
Methods: Twenty-two patients underwent bilateral same-day underlay myringoplasty, and all cases were consistent with the indications for myringoplasty. The preoperative hearing and postoperative hearing at three months were compared, and the postoperative symptoms and complications were observed. Forty patients underwent monaural myringoplasty as the control group over the same period. All cases were followed up for 1 - 3 years.
Results: The postoperative hearing was increased by an average of 18 dB, and the rate of closure of tympanic membrane perforation was 93.2% (41/44). There were seven patients with ear fullness after operation in the bilateral myringoplasty group and two patients in the control group (χ(2) = 4.5374, P = 0.0332). There were no differences in the postoperative hearing improvement, the rate of closure and the rates of other discomfort symptoms except for ear fullness between the two groups (P > 0.05).
Conclusion: It was feasible and safe to perform bilateral same-day myringoplasty for bilateral tympanic membrane perforation, but the postoperative temporary discomfort of bilateral ear fullness should be informed the patients in advance.
