Observational Study
Analysis of Risk Factors and Prediction Model for Recurrence of Hemifacial Spasm After Radiofrequency Ablation.
Computed tomography (CT)-guided percutaneous stylomastoid foramen puncture radiofrequency ablation for the treatment of hemifacial spasm has a significant clinical effect; however, related risk factors for recurrence have not been studied. ⋯ Long operation times and high-grade facial paralysis can reduce the risk of recurrence in patients with facial spasms. The constructed recurrence prediction model could serve as a reference for clinical diagnosis and treatment.

Complete separation of the vertebrobasilar artery (VBA) from the trigeminal nerve by microvascular decompression is technically challenging. This paper evaluates the transposition method using Teflon sling for trigeminal neuralgia (TN) caused by the VBA. ⋯ Our method for trigeminal neuralgia caused by VBA was very effective, but the complication rate of cranial nerve disorders was also high. A high rate of complications implied the technical difficulty of extensive vascular mobilization requiring long duration of surgery. Macrovascular decompression surgery is more descriptive of this surgery instead of microvascular decompression surgery.

Primary trigeminal neuralgia (PTN) is characterized by chronic neuropathic pain. There are few studies exploring masticatory muscle changes in patients with PTN. This study evaluated the changes in the masticatory muscles using magnetic resonance imaging (MRI) and the predictive factors of masticatory muscle changes in patients with PTN. ⋯ Logistic regression analysis demonstrated that neurovascular conflict (NVC) significantly predicted mastication muscle atrophy (P = .037). Patients with PTN had higher rates of masticatory muscle atrophy and edema. The assessment of NVC may be a preoperative imaging biomarker to predict atrophy in PTN.

The postoperative course of hemifacial spasm (HFS) varies. We analyzed the clinical outcomes from 1 to ≥5 years after microvascular decompression (MVD) in patients with HFS. ⋯ Long-term outcomes from 1 to ≥5 years after MVD in patients with HFS were diverse. Nondiabetes, intraoperative offending vessel without a vein, and intraoperative discoloration of the facial nerve were better prognostic factors for outcomes at ≥5 years postoperatively. It is advisable to consider these results when evaluating the long-term outcomes of this surgery.

Microvascular decompression (MVD) has grown as a first-line surgical intervention for severe facial pain from trigeminal neuralgia and/or hemifacial spasm. We sought to examine the safety and cost-benefits of discharging patients with MVD within 1 day of admission. ⋯ In our experience, MVDs are a safe, elective intervention. Our findings suggest that postoperative day 1 discharge in patients with an uncomplicated postoperative course may be safe while improving hospital resource use.
