Hemifacial Spasm*

Vestibular Paroxysmia and facial spasm may be caused by vascular compression of the vestibular and facial root entry zone. We report a case of paroxysmal nystagmus accompanied by facial spasm and which is well visualized by three-dimensional reconstruction images. The 3-dimensional reconstruction image supports the view that vestibular paroxysmia may occur with hemifacial spasm simultaneously due to vascular compression.

OBJECTIVE

To report the demographics, clinical characteristics, and surgical outcomes after microvascular decompression (MVD) for hemifacial spasm (HFS) in the Philippine General Hospital (PGH).

Between January 2018 to December 2022, the division of Neurosurgery at PGH performed thirty-four MVD operations for Primary HFS. Records were retrospectively reviewed, and pertinent demographic, intra-operative findings, outcomes, and complications were analyzed.

The overall success rate is 88.2%, with a median follow-up at 15 months. Repeated measures ANOVA showed that post-op HFS and follow-up HFS grades were significantly lower than pre-op HFS grades (F=17.46, df=33, p < 0.0001). HFS average age of symptom onset was early at 38.5 years, 11.8% of which wereCONCLUSION

MVD at PGH is a viable choice treatment option for Filipino patients with success rates comparable to internationally published studies. Besides improving surgical technique, improvement of referral systems may help make surgery more accessible.

PURPOSE: To investigate the applicability of the new three-dimensional overlapped reconstruction MR angiography (3-D ORMRA) technique in patients with hemifacial spasm and to compare the new 3-D reconstruction images with conventional MRA source images. MATERIALS AND METHODS: The study group comprised 27 patients with surgically proven hemifacial spasm. In all patients, conventional MRA source images and 3-D fast imaging employing steady-state acquisition (FIESTA) images were obtained prospectively. After 3-D MR angiographic images were obtained, the 3-D MRA and FIESTA images were overlapped at the workstation by using GE A/W 4.2 add/sub software. We analyzed the relationship between the offending vessels and root exit zone of the facial nerve using both 3-D ORMRA images and conventional MRA source images. RESULTS: In 25 of 27 patients, the offending vessel at the REZ of the facial nerve could be correctly identified on conventional MRA source images. In all patients, the presumed offending vessels depicted by the overlapped 3-D reconstruction MRA image corresponded well with the intraoperative findings. The 3-D reconstruction image showed more clear visualization of the spatial relationship between the offending vessels and the root exit zone of the facial nerve. CONCLUSION: The overlapped 3-D reconstruction MR angiography technique is very useful and informative in patients with hemifacial spasm, as compared with conventional MRA angiography technique.

The authors present a case of isolated dural arteriovenous fistula (DAVF) in the transverse sinus, which developed six years after microvascular decompression caused by hemifacial spasm via suboccipital craniectomy. The lesion was successfully treated by transarterial embolization using Onyx. We reviewed the related radiologic and therapeutic features of DAVF involving an isolated sinus and described the feasibility of the use of Onyx.

Afloqualone is a centrally acting muscle relaxant and has been used in therapy for musculotensive diseases. A 35-year-old female had been taking afloqulaone for a left hemifacial spasm for one month. The patient visited our hospital with erythematous papules and patches on the sun exposed area. A photopatch test with afloqualone ointment with the concentration of 0.1%, 1%, 5% turned out negative. An oral provocation test was also done and it showed a positive result with a decrease of MED to UVA (10 J/cm²).

A series of 61 cases of primary hemifacial spasm have been evaluated by means of blink reflex and needle electromyography and their result compared with unaffected site. The R1 and R2 response and late acti-ity. After activity in blink reflex. And electrical activity in EMG at rest were observed. The results of study were as in the followings: 1) The arnplitude of large R1 and R2 responses were increased in affected side in contrast to unaffected side. 2) late activity(72.2%) and after activity(83.6%) were observed in only affected side at rela-ti-ely Iong duration, as well as regular interval spontaneous repetivive discharges in EMG at rest. This result of large R1 and R2 responses could be compatible with ephaptic ransmission, but late activity, after activity, and spontaneous repetitive MUPs could be explained hyperexcitability of the facial motor nucleus rather than autoexcitation of peripheral facial nerve. Additionally the authors thought that the use of conventional blink reflex as well as specialized blink reflex tests could be very useful for the diagnosis of hemifacial spasm and for the evaluation of it's course.
