Long-Term Nervus Intermedius Function Outcomes and Their Predictors in Patients With Vestibular Schwannoma After Microsurgery

Long-term NI dysfunction is a common and under-recognized complication after VS surgery. Poor FN function and unserviceable hearing at discharge independently predict NI dysfunction. In addition, cystic tumor type and poor FN function predict taste dysfunction, whereas poor FN function alone predicts eye dryness. These factors may aid in prognostication and guide surgical planning and postoperative counseling.
