Abstract

Preeclampsia is one of the most common complications of pregnancy in the world. In Indonesia, the incidence of preeclampsia lies within 3–10% of all pregnancies every year. Preeclampsia is a multisystem disorder that causes endothelial dysfunction and vasospasm that may lead to ischemia and organ damage especially to the end organs. Cochlea serves as an end organ and is therefore vulnerable to damage under ischemic conditions. This research aimed to understand the role of preeclampsia on the destruction of cochlear outer hair cells function. Subjects were pregnant women who were hospitalized in the Obstetrics and Gynecology Ward of Sardjito Hospital. Diagnosis of preeclampsia was obtained by defining level of high blood pressure measurement and quantitative 24 hours of proteinuria. Meanwhile, cochlear outer hair cell function was measured by the distortion product otoacoustic emission (DPOAE). The DPOAE results showed that REFER presented in 6 (10%) patients with preeclampsia and none in those without preeclampsia groups. This result demonstrated preeclampsia as one of the risk factors for impaired function of cochlear outer hair cells.
