Purpose:
This study explores the changes in hearing thresholds in pregnancy.
Materials And Methods:
A prospective hospital-based observational study was performed with a total of 69 patients in the age-group of 18 to 40 years. Patients underwent hearing assessment twice during the study period. Conventional pure tone audiometry and impedance audiometry were performed, first during the antepartum period (28-32 weeks of gestational age) and second time during the postpartum period (6 weeks postpartum).
Results:
Significant difference was seen between the average of air conduction threshold values at speech frequencies when antepartum values were compared with postpartum values.
Conclusion:
The alterations in hearing sensitivity in pregnant females which improved during the postpartum period can be attributed to pregnancy.
