PURPOSE OF REVIEW: To evaluate the recent and significant contributions to the literature that examine hearing preservation outcomes and prognostic factors in vestibular schwannoma microsurgery.
RECENT FINDINGS: Hearing preservation rates overall range considerably between 2 and 93% in recent studies. There are a number of factors that have been reported to be significant in the prediction of hearing preservation. Characteristics such as approach, results of preoperative neurophysiological testing, tumor size and nerve of origin have long been reported. A more recent contribution to the literature has included the association between MRI T2 signal in the fundus of the internal auditory canal and hearing preservation. This review provides a summary of some of the landmark studies in conjunction with more recent work detailing the prognostic factors for hearing preservation in the surgical management of vestibular schwannoma.
SUMMARY: Hearing preservation in vestibular schwannoma surgery has undergone tremendous evolution over the past 50 years. In this review, we outline the prognostic factors that predict hearing preservation and describe recent contributions.
