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