To study hearing loss in healthy pregnant women. Tertiary care hospital. Prospective study. We screened fifty healthy, non-complicated pregnant women (study group) in the third trimester for hearing loss who had no previous history for the same. Fifty healthy, non-pregnant women (control group) were also screened for hearing loss with a normal pure tone audiogram (PTA) for evidence of hearing loss. Thirteen women in the study group had evidence of hearing loss, in the form of absence of distortion product otoacoustic emission (DPOAE), though the PTA was within normal limits. In the control group, two women had evidence of hearing loss, in the form of absence of DPOAE with normal PTA. This study proves that pregnancy exacerbates hearing loss, if the patient has any risk factors for the same.
研究健康孕妇的听力损失情况。三级护理医院。前瞻性研究。我们对五十名健康、无并发症的孕晚期孕妇（研究组）进行听力损失筛查，这些孕妇既往无听力损失病史。另外对五十名健康非孕妇（对照组）进行听力损失筛查，其纯音听力图（PTA）正常以作为听力损失的证据。研究组中有十三名女性存在听力损失证据，表现为畸变产物耳声发射（DPOAE）缺失，尽管其PTA在正常范围内。对照组中有两名女性存在听力损失证据，表现为DPOAE缺失但PTA正常。本研究证明，如果患者有任何听力损失的风险因素，怀孕会加重听力损失。
