Facial nerve function after vestibular schwannoma surgery

Abstract

The main factor influencing postoperative FN function was tumor size. Although there was a progressive deterioration in FN function outcome in relation to tumor size, a cutoff point between satisfactory and unsatisfactory results could be identified at around 2 cm in maximum extrameatal tumor diameter, with the "optimal size" for surgery identified at < 1 cm. This finding emphasizes the importance of an early diagnosis and should be kept in mind when selecting the correct timing for VS removal. For small lesions, the results following a middle cranial fossa approach were significantly worse as compared with those following the translabyrinthine and retrosigmoidretrolabyrinthine approaches.

Technical nuances of resection of giant (> 5 cm) vestibular schwannomas: pearls for success

“…This is especially true with giant tumors, as tumor size is the main factor predicting postoperative facial weakness. 7 Patients with an incomplete eye closure may undergo gold weight placement within the eyelid and/or tarsorrhaphy. Facial reanimation procedures may be considered if facial nerve function does not return within 1 year postoperatively.…”

Acoustic Neuroma Related Eye Involvement and Its Treatment

“…Bunlar sarkoidoz, intrakraniyal kanamalar, menenjit ve kafa içi tümörler olarak sayılabilir. Serebellopontin açıda en sık görülen tümör olan akustik nörinom olgularında cerrahi öncesi ya da cerrahiye bağlı olarak sıklıkla vestibulokohlear sinir ve fasiyal sinir etkilenmektedir, nadiren trigeminal sinir, abdusens sinir ve daha alt kafa sinirlerin etkilendiği de bildirilmiştir (6,10,11). Bizim olgumuzda tümör basısına ya da cerrahi sırasında oluşan sinir hasarına bağlı olarak 4 kraniyal sinirde paralizi izlendi.…”

Surgical Approaches for Vestibular Schwannoma

“…In a 2011 report, Falcioni et al [22] compared facial nerve outcomes across surgical approaches for 439 tumors that extended less than 1 cm into the cerebellopontine angle. No statistical difference was identified between the translabyrinthine and retrosigmoid approaches, but both were statistically more likely to yield better facial nerve outcomes at 1 year following resection than the middle cranial fossa approach.…”
