Ren Y, Tawfik KO, Mastrodimos BJ, et al. - A retrospective case series with chart review was conducted to distinguish preoperative radiographic predictors of hearing preservation (HP) after retrosigmoid resection of vestibular schwannomas (VSs). Between February 2008 and December 2018, adult patients with VSs < 3 cm and word recognition scores (WRSs) ≥ 50% who had undergone retrosigmoid resection and attempted HP were distinguished. Researchers assessed pure tone average (PTA), WRS, and magnetic resonance imaging radiographic data, including tumor diameter and dimensional extension relative to the internal auditory canal (IAC). The study included a total of 151 individuals. It was shown that the rates of HP are highest in patients with small intracanalicular VSs and good preoperative hearing. Greater posterior and caudal tumor extension relative to the IAC may portend worse hearing outcomes, for tumors extending into the CPA.
