Data from three academic medical centers were evaluated, including the following: imaging, videonystagmography (VNG)\/vestibular evoked myogenic potential (VEMP) testing, audiometric assessment, and surgical repair. Outcome measures included the following: 1) Description of audio\u2010vestibular symptoms, 2) mean pre\u2010 and post\u2010operative pure tone average (PTA), word recognition score (WRS), and air bone gap (ABG).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 14 patients were included; 86% were male. Approximately 43% were found to have bilateral SSCD on imaging, with 57% of patients pursuing surgical management. The most common presenting symptoms included pulsatile tinnitus (93%), autophony (79%), and hearing loss (64%). Approximately 36% of patients underwent VNG\/VEMP testing, with 83.3% of those demonstrating abnormal results. The mean audiometric findings on the symptomatic side included an air\u2010conduction PTA of 38.0\u2009dB, bone\u2010conduction PTA of 24.3\u2009dB, WRS of 81%, and ABG of 17.9\u2009dB. Among patients who underwent surgery (57%), there was no significant change in the air\u2010conduction PTA, bone\u2010conduction PTA, or WRS (<jats:italic>P<\/jats:italic>\u2009&gt;\u2009.05). However, there was an improvement in the ABG (preoperative\u00a0=\u00a022.8\u2009dB versus postoperative\u00a0=\u00a09.7\u2009dB; <jats:italic>P<\/jats:italic>\u00a0=\u00a0.005).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Head trauma may be a potentiating event for SSCD syndrome.
