Objective:To investigate the clinical value of tympanic membrane repairment with modified ear canal flap under endoscope. Methods:A retrospective analysis was conducted on the clinical data of 62 patients who underwent simple tympanic membrane perforation repair surgery in our hospital from August 2019 to January 2023. All patients were divided into two groups: 37 cases in the otoscopy group and 25 cases in the microscope group. The surgical duration, postoperative pain response, and postoperative tympanic membrane healing and hearing recovery were compared between the two groups. Results:Compared with the microscope group, the total surgical duration of the otoscopy group was significantly shortened[（70.4±13.2） min vs. （102.8±17.5） min, P<0.001], and there was a statistically significant difference in postoperative VAS pain score[（3.1±1.2） vs. （6.5±1.4）, P<0.001]. The two groups achieved tympanic membrane healing and no infection occurred after operation. There was no significant difference in postoperative hearing recovery between the two groups（P>0.05）. Conclusion:Modified tympanic membrane repairment through otoscope can greatly shorten the operation time and reduce the hospitalization cost, which is more suitable for the application of primary hospitals.

INTRODUCTIONThe present study aimed to obtain preliminary tympanometric data of young Malay adults and to compare the results between genders.

METHODS96 undergraduate students (49 males and 47 females), aged 19-25 (mean and standard deviation 21.14 +/- 1.31) years, participated in this study. Otoscopic examination, pure tone audiometry, qualitative tympanogram and ipsilateral acoustic reflex were measured to ensure a clear ear canal, normal hearing and normal middle ear function, prior to tympanometric measurement. As a result, a total of 154 ears (80 ears from males and 74 ears from females) were selected for further statistical analyses. The tympanometric parameters measured were peak compensated static acoustic admittance (Peak Y(tm)), tympanometric width (TW) and equivalent ear canal volume (V(ea)).

RESULTSThe results showed that the mean Peak Y(tm), V(ea) and TW for males were 0.81 mmhos, 1.48 cubic cm and 113.67 daPa, respectively. The mean Peak Y(tm), V(ea) and TW for females were 0.63 mmhos, 1.12 cubic cm and 98.04 daPa, respectively. Males were found to have significantly higher mean V(ea) and mean Peak Y(tm) than females. However no significant gender difference was observed in the mean TW.

CONCLUSIONThe current study suggests that young Malay adults may require gender-specific Peak Y(tm) and V(ea) values when implementing a quantitative approach in tympanogram interpretation.
