Abstrakt: Conclusion: Sudden sensorineural hearing loss (SSNHL) in pregnancy is rare. It usually occurs in the third trimester. SSNHL in pregnancy does not increase risks during delivery or subsequent stroke.
Objectives: This study aimed to investigate the incidence and to determine the factors associated with SSNHL in pregnancy.
Method: Data were retrieved from Taiwan's National Health Insurance Database (NHIRD), covering the years 2000-2009. Patients admitted for SSNHL during pregnancy were enrolled. An age-matched controlled cohort was randomly selected from pregnant women without SSNHL in the NHIRD. The clinical characteristics of both cohorts were collected for further analyses.
Results: Thirty-three patients with SSNHL in pregnancy were enrolled. The estimated incidence of SSNHL in pregnancy in Taiwan was 2.71 per 100,000 pregnancies. The incidence of SSNHL in pregnancy was lower than that of the general female population. The incidence of SSNHL in the third trimester was higher compared to the other two. The incidence of SSNHL occurring in the 30-39 years old age group was higher than other groups. Women with better socioeconomic status had a higher incidence of SSNHL. There were no identified systemic diseases before SSNHL. Two patients had pre-eclampsia and one patient had premature delivery. Nevertheless, SSNHL in pregnancy did not increase the risk for stroke.
