Lee SY, et al. - Utilizing a nationwide population cohort, researchers conducted a longitudinal case-control study to assess the risk of sudden sensorineural hearing loss (SSNHL) during the pregnancy and postpartum periods. Data were gathered from 63,331 pregnant/postpartum candidates who were matched 1:2 by age, income, the region of residence, and medical history with 126,662 control candidates using the Korean National Health Insurance Review and Assessment Service. According to results, the SSNHL rate was not higher vs the control group during the pregnancy period. During pregnancy, the adjusted odds ratio of SSNHL was 0.32. During the postpartum period, the adjusted odds ratio of SSNHL was 1.04. During the pregnancy/postpartum period, the risk of SSNHL in the patients was not higher than that in controls, regardless of age and specific subperiod. Overall, the authors concluded that there was no higher risk of SSNHL for pregnant and postpartum women.
