A persistent stapedial artery (PSA) is a rare embryologic remnant that typically involutes at week 10 of embryogenesis. However, if it is persistent, it may lead to conductive hearing loss and pulsatile tinnitus. It is of utmost importance to identify such an anomaly, as it leads to serious complications intraoperatively if overlooked. Proper clinical and radiological assessment helps an otologist recognize the PSA. We describe the case of a 24-year-old female presenting with a chronically discharging ear in addition to pulsatile tinnitus and conductive hearing loss with an incidental finding of a PSA upon otoscopy.
永存镫骨动脉(PSA)是一种罕见的胚胎残余物,通常在胚胎发育第10周时退化。然而,如果它持续存在,可能会导致传导性听力损失和搏动性耳鸣。识别这种异常至关重要,因为如果术中忽视,可能会导致严重并发症。恰当的临床和影像学评估有助于耳科医生识别永存镫骨动脉。我们描述了一名24岁女性的病例,该患者除搏动性耳鸣和传导性听力损失外,还有慢性耳流脓,耳镜检查时偶然发现永存镫骨动脉。
