Abstract :

Background: Auditory functions are very important for communication, which in turn have leveraging influence on several sectors of lifestyle. Hormonal changes in menstrual cycle can affect fluid homeostasis, which may affect Auditory functions and thus may impinge women�s performance in various aspects of lifestyle. Aim: To determine the Audiological status in different frequencies in different phases of the menstrual cycle. Objectives: 1) To perform Pure Tone Audiometry in pre–menstrual phase and post–menstrual phase. 2) To compare the results of Audiometry in pre–menstrual phase and post–menstrual phase. Methods: After procuring the Ethical Committee clearance, this prospective study was conducted on 60 healthy female subjects with regular menstrual cycle with consideration of inclusion and exclusion criteria. Written informed consent was taken and Menstrual History Questionnaire was administered. Each subject was instructed to come to the lab twice, once during pre–menstrual phase (18th to 25th day), and then during post–menstrual phase (8th to 12th day) of the Menstrual cycle. Anthropometric measurements were taken. Audiometric tests were performed in both the ears for Auditory Acuity using Pure Tone Audiometry with ARPHI 500 MK in both the phases. Using appropriate tools, results were compiled and statistically analyzed. Results: Statistically significant increase in weight was seen in pre–menstrual phase (P<0.01). He� threshold values were compared between the two phases and statistically significant decibel loss was observed at all frequencies in both the ears for air conduction and bone conduction in the pre–menstrual phase (P<0.01). Conclusion: Statistically significant decibel loss was seen in both the ears for all frequencies in both air conduction and bone conduction in pre–menstrual phase attributing to increased Ovarian Hormones modulating the auditory functions at various levels of auditory system.
