[Clinical analysis of bilateral same-day myringoplasty for 22 cases with bilateral tympanic membrane perforation].

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.

[Three-axis otoconia maneuver treatment in benign paroxysmal positional vertigo].

OBJECTIVE: To evaluate three-axis otoconia maneuver (TOM) for benign paroxysmal positional vertigo (BPPV). METHODS: The data from twenty BPPV patients who received three-axis otoconia maneuver treatment and 20 BPPV patients who received canalith repositioning (CRP) maneuver treatment were analyzed retrospectively. RESULTS: There were 17 patients received 1 TOM session and 3 patients received 2 TOM sessions while 16 patients received 1 CRP session and 4 patients received 2 CRP sessions. The chi-square (X2) test was used in evaluating the association between two independent samples in a contingency table. Both methods had no statistically significant. The significance level for statistical tests was 5% (alpha = 0.05). CONCLUSIONS: Three-axis otoconia maneuver could be effective used in benign paroxysmal positional vertigo with the advantage of repeatedly practicable and instrumental.
