  • Title: How I do it: hearing preservation in large vestibular schwannomas using vestibular nerve fiber preservation technique.
    Author: Khanna O, Hogan E, Alvarez R, Youssef AS.
    Journal: Acta Neurochir (Wien); 2024 Feb 26; 166(1):105. PubMed ID: 38403779.
    Abstract:
    BACKGROUND: To improve hearing function after resection of large vestibular schwannomas, we describe a strategy of vestibular-nerve-fiber preservation. Anatomical considerations and stepwise dissection are described. METHOD: Steps include locating the vestibular nerve at the brainstem and identifying a dissection plane between nerve fibers and tumor capsule. Using this plane to mobilize and resect tumor reduced manipulation and maintained vascularity of underlying cochlear and facial nerves. CONCLUSION: Preservation of hearing function is feasible in large vestibular schwannomas with vestibular-nerve-fiber preservation. Reducing manipulation and ischemic injury of underlying cochlear and facial nerves thereby helped facilitate hearing preservation, even in large tumors.
