Review Case Reports
Microvascular decompression for oculomotor nerve palsy due to non-aneurysmal neurovaslur conflict: 5 cases report and literature review.
Oculomotor nerve palsy (ONP) is frequently caused by aneurysm compression and diabetes mellitus. However, nonaneurysmal compression (nAVC) of the oculomotor nerve is a condition rarely reported in the literature. Cases treated with microvascular decompression (MVD) for nAVC-induced ONP (nAVC-ONP) are exceptionally rare. ⋯ Neurovascular conflict has been proposed as another possible cause of ONP in a limited number of cases. Based on our findings, MVD is a potentially effective solution for patients experiencing oculomotor nerve palsy resulting from nonaneurysmal neurovascular conflicts. It holds great promise for significantly alleviating symptoms and improving overall quality of life.

Visualization of the nervus intermedius during microvascular decompression in hemifacial spasm: anatomical study.
The surgical anatomy of the nervus intermedius (NI) is highly variable. The aim of this study was to describe the anatomy of the NI during endoscope-assisted microvascular decompression (MVD) in hemifacial spasm (HFS), and the involvement of the nerve in the vascular conflict. ⋯ The anatomy of the NI is for the first time evaluated endoscopically in MVD for HFS. The nerve had various anatomical patterns that were clearly identified. Further studies to evaluate the compression patterns in relation to NI neuralgia are warranted.

Comparative Study
Comparison of the efficacy of complete endoscopic and microscopic vascular decompression in the treatment of classical Trigeminal neuralgia.
To compare whether there is a difference in the efficacy of complete endoscopic microvascular decompression (EVD) and microscopic microvascular decompression (MVD) in patients with classical trigeminal neuralgia (CTN). ⋯ For CTN patients, compared with traditional MVD, EVD is also safe and effective and has the advantage of shorter decompression time.The predictive results of prognostic factors also suggest that CTN patients may benefit more from early surgical treatment.

External assessment of preoperative scores for predicting outcome after microvascular decompression for trigeminal neuralgia.
Recently, two scoring systems have been developed for predicting pain-free outcomes after microvascular decompression (MVD). Evaluation of these scores on large external datasets has been limited. In this study, the authors aimed to evaluate the performance of published MVD scoring systems in predicting pain-free outcome. ⋯ Both the Hardaway and Panczykowski scores may be useful for predicting postoperative pain-free duration in TN patients, and their utility may be greatest when scores are clustered. Continued refinement of both scoring systems will help to improve our ability to predict patient outcomes after MVD.

Hemifacial spasm (HFS) is triggered by neurovascular compression mostly at the root entry/exit zone of the facial nerve. HFS with the responsible blood vessel located in the internal auditory canal (IAC) is a very rare occurrence. In our case, the HFS was triggered by compression of the anterior inferior cerebellar artery (AICA) loop on the facial nerve in the IAC. ⋯ The attachment of the facial nerve to the tortuous AICA loop coupled with the pulsatile impulse of tortuous AICA loop may have resulted in the entrapment and compression of the CN VII in the IAC.
