Abstract:
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.
