Summary: The study demonstrates the utility of electromyographic follow-up in facial nerve reconstruction, with hemihypoglossal-facial anastomosis being an optimal solution for restoring facial function. Electromyography can predict initial reinnervation activity after reconstructive procedures, aiding in identifying insufficiently recovering patients during follow-up.

Summary: Preoperative functional testing cannot reliably predict the presence of intracranial facial schwannomas. Hearing is better in facial schwannomas, especially in lower frequencies, while patients with vestibular schwannomas have worse hearing outcomes.

Summary: The study aimed to identify important prognostic factors related to facial paralysis after vestibular schwannoma surgery and develop a nomogram for predicting facial nerve outcomes. Tumor size, fundal fluid cap sign, cerebrospinal fluid cleft sign, and expansion of the affected side of the internal auditory canal were found to be independent predictors. A nomogram model was constructed based on these factors.

Summary: Preoperative differentiation between facial nerve schwannoma (FNS) and vestibular schwannoma (VS) can be challenging. This study provides clinical and imaging features to distinguish FNS from VS and offers recommendations for surgical decision-making in intraoperatively diagnosed FNS.

Summary: Facial nerve outcomes one year after microsurgical resection are poorer in patients with NF2 tumors compared to sporadic tumors, particularly for tumors with a volume greater than 3 cm³ and those classified as NF2 tumors.

Summary: Intraoperative neurophysiological monitoring is crucial in vestibular schwannoma surgery to prevent nerve injury. Repeated direct nerve stimulation and a detected decreased amplitude might show facial nerve function deterioration.

Summary: The study revealed that patients with tumor volume >3 cm(3) had worse facial nerve outcomes 12 months following surgical resection. Tumor volume was identified as a key factor affecting facial nerve function outcomes.

Summary: This study aimed to identify dosimetric predictive factors for facial nerve paralysis in patients with vestibular schwannomas treated with Cyberknife hypofractionated stereotactic radiotherapy. The results showed that prescriptions with a maximum dose point exceeding 30 Gy and 33 Gy substantially increased the risk of facial paralysis. Additionally, GTV minimal dose over 22 Gy, GTV mean dose over 29 Gy, PTV mean dose over 27 Gy, and PTV maximal dose of 32 Gy were identified as significant predictive factors for radiation-induced facial nerve dysfunction. Increasing the doses of hypofractionated stereotactic radiotherapy may lead to higher facial nerve toxicity and lower local control rates.

Summary: This study shows that the position of vestibular schwannoma relative to the IAC axis can be used along with tumor size to predict postoperative facial outcomes. A greater proportion of tumor posterior to the IAC axis was associated with significantly better facial outcomes.

Summary: This study aimed to optimize a multi-shell rs-DWI protocol and develop a novel post-processing pipeline to accurately delineate the facial-vestibulocochlear complex within the skull base region, and evaluate its intraoperative accuracy using neuronavigation and tracked electrophysiological recordings.

Summary: This study compared the efficacy of Gamma Knife radiosurgery (GKRS) with conventional surgery for small vestibular schwannomas (VS) and found that GKRS was superior to surgery in hearing preservation, while there was no significant difference in tumor control between the two treatment methods.

Summary: This retrospective study aimed to investigate the impact of morphologic and neurophysiological factors on the short- and long-term facial nerve function after vestibular schwannoma resection. A multiparametric score, Facial Nerve Outcome Score (FNOS), was developed and shown to be a reliable predictor of facial nerve function.

Summary: The facial nerve, a mixed nerve, has sensory and motor fibers, with its main branch located in the cerebellopontine angle. Facial nerve dysfunction can occur in skullbase tumors and Bell's palsy, with recovery outcomes varying between the two. Recent advances in MRI technology have allowed for better visualization of the facial nerve in the presence of large tumors.
