The present study aimed to obtain preliminary tympanometric data of young Malay adults and to compare the results between genders.
96 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)).
The 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.
The 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.
本研究旨在获得年轻马来成年人的初步鼓室图数据，并比较性别之间的结果。
本研究纳入了 96 名年龄在 19-25 岁（平均值和标准差为 21.14 ± 1.31 岁）的本科学生（49 名男性和 47 名女性）。在进行鼓室测量之前，通过耳镜检查、纯音听力测试、定性鼓室图和同侧声反射来确保耳道清晰、听力正常和中耳功能正常。最终，共选择了 154 只耳朵（80 只来自男性，74 只来自女性）进行进一步的统计分析。测量的鼓室图参数包括峰值补偿静态声导纳（Peak Y(tm)）、鼓室图宽度（TW）和等效耳道容积（V(ea)）。
结果显示，男性的平均 Peak Y(tm)、V(ea)和 TW 分别为 0.81 毫西门子、1.48 立方厘米和 113.67 达帕，女性的平均 Peak Y(tm)、V(ea)和 TW 分别为 0.63 毫西门子、1.12 立方厘米和 98.04 达帕。男性的平均 V(ea)和平均 Peak Y(tm)明显高于女性，但 TW 的平均无显著性别差异。
本研究表明，在实施鼓室图解释的定量方法时，年轻马来成年人可能需要特定性别的 Peak Y(tm)和 V(ea)值。
