Objective comparison between perforation and hearing loss

INTRODUCTION: There appears to be no relationship between the size of tympanic perforations and hearing loss. Some studies in the literature have assessed this connection, with conflicting data and without proper methodology, especially concerning the measurement of the size of the perforation, which was performed in a subjective manner. OBJECTIVE: To evaluate the size of tympanic perforations and to relate them to hearing loss in four different sound frequencies through the use of an objective method. METHODS: Transversal retrospective study. The present study evaluated 187 perforations through digital imaging, calculated the percentages of the tympanic membrane that was perforated using ImageScope software version 11.1.2.760 and correlated perforations size with hearing loss at four frequencies. RESULTS: Data were statistically analyzed using Pearson's correlation test. CONCLUSION: There was no significant relationship between the size of tympanic perforations and hearing loss in the four analyzed frequencies.引言：目前尚无明确证据表明鼓膜穿孔（tympanic perforations）大小与听力损失（hearing loss）之间存在关联。既往文献中虽有多项研究探讨二者的相关性，但所得数据存在矛盾，且研究方法存在缺陷，尤其在穿孔大小的测量环节，均采用主观评估方式。 研究目的：采用客观测量方法，评估鼓膜穿孔的大小，并分析其与四种不同声频下听力损失的相关性。 研究方法：本研究为横断面回顾性研究。通过数字成像技术对187例鼓膜穿孔样本进行分析，使用ImageScope软件（版本11.1.2.760）计算鼓膜穿孔所占百分比，并将穿孔大小与四种声频下的听力损失进行相关性分析。 研究结果：采用Pearson相关检验对数据进行统计学分析。 研究结论：在所分析的四种声频中，鼓膜穿孔大小与听力损失均无显著相关性。
