Intraoperative Corticobulbar Motor Evoked Potential in Cerebellopontine Angle Surgery: A Clinically Meaningful Tool to Predict Early and Late Facial Nerve Recovery

Giuseppe Maria Della Pepa et al.

Summary: This study confirms that intraoperative FMEPs are reliable predictors of early and late postoperative FNF in CPA surgery and can be easily integrated with standard intraoperative neuromonitoring techniques.

Surgical Management of Malignant Glioma in the Elderly

Julia Klingenschmid et al.

Summary: This study analyzed the surgical treatment outcomes of elderly patients with malignant glioma. The results showed that gross total resection (GTR) can achieve better functional outcomes and survival in elderly patients. Age seems to have little influence on overall survival in surgically treated patients, but high preoperative functional performance is necessary.

Pre- and intra-operative prognostic factors of facial nerve function in cerebellopontine angle surgery

Francesco Gazia et al.

Summary: The study evaluates the ability of pre- and intraoperative factors related to electromyography and direct electrical stimulation of the facial nerve to predict facial nerve function in the short and long term after cerebellopontine angle tumor resection. Results show correlations between tumor size, minimum stimulation threshold, compound muscle action potential, and facial function in both short and long term. Higher immediate facial paralysis grades correspond to a higher risk of poor outcomes after one year.

Monitoring Cortico-cortical Evoked Potentials Using Only Two 6-strand Strip Electrodes for Gliomas Extending to the Dominant Side of Frontal Operculum During One-step Tumor Removal Surgery

Taiichi Saito et al.

Summary: In 7 cases of glioma extending to the left frontal operculum, FLA was identified by functional mapping during awake craniotomy. CCEPs were successfully recorded using two 6-strand strip electrodes, and postoperative recovery of language function was monitored.

Tailored Approach and Multimodal Intraoperative Neuromonitoring in Cerebellopontine Angle Surgery

Alessandro Izzo et al.

Summary: This paper presents an integrated approach to cerebellopontine angle (CPA) surgery, incorporating the use of technology such as neuronavigation and intraoperative neuromonitoring (IONM) techniques to improve the treatment effectiveness and reduce surgical risks.

Postoperative Impact of Pontocerebellar Angle Surgery on the Quality of Life in Patients with Vestibular Schwannoma

Valentina Foscolo et al.

Summary: This study evaluated the quality of life in surgically treated patients with large and giant vestibular schwannomas using the PANQOL questionnaire. The results showed that the postoperative quality of life was acceptable, although there were greater impacts on hearing and balance. Therefore, vestibular rehabilitation programs and strategies to improve postoperative hearing are needed.

Clinical Predictors of Facial Nerve Outcomes After Surgical Resection of Vestibular Schwannoma

Yin Ren et al.

Summary: Clinical predictors of facial nerve outcomes after microsurgical resection of vestibular schwannoma were identified, indicating excellent outcomes can be achieved with this procedure. Gross total resection and >= 100-mu V intraoperative FN electromyographic response were found to predict excellent FN outcomes.

Predictive Ability of Direct Electrical Stimulation on Facial Nerve Function Following Vestibular Schwannoma Surgery: A Systematic Review and Meta-analysis

Alexandra E. Quimby et al.

Summary: According to the study findings, MST values of 0.05 mA and 0.10 mA demonstrate sensitivity and specificity for facial function in the long term, while CMAP amplitude less than 500 mu V shows high sensitivity for poor short-term facial function. Other DES parameters may have the potential to accurately predict both short- and long-term postoperative facial function, although they have not been as extensively studied.

Neurophysiological monitoring of the laryngeal adductor reflex during cerebellar-pontine angle and brainstem surgery

Maria J. Tellez et al.

Summary: This study evaluated the impact of posterior fossa and brainstem surgery on laryngeal function by monitoring LAR and vocal-CoMEPs. It found that permanent LAR-SC or loss correlated with postoperative laryngeal dysfunction, while timely surgical adjustments could prevent irreversible damage.

The Impact of Neuronavigation on the Surgical Outcome of Microvascular Decompression for Trigeminal Neuralgia

Francois Yves Legninda Sop et al.

Summary: Neuronavigation significantly reduced craniotomy size, surgical duration, and cerebrospinal fluid leak incidence in patients with trigeminal neuralgia undergoing microvascular decompression surgery. It is recommended to routinely implement neuronavigation in this type of surgery.

Intraoperative transcranial facial motor evoked potential monitoring in surgery of cerebellopontine angle tumors predicts early and late postoperative facial nerve function

Ryo Hiruta et al.

Summary: A new method using FMEP amplitude ratios can predict facial nerve function recovery in cerebellopontine angle tumor surgery. Intraoperative MBR and FBR show significant correlation with early postoperative FNF, while RV demonstrates good predictive power for FNF recovery in the late postoperative period.
