Object Microvascular decompression (MVD) of the facial nerve is an effective treatment for hemifacial spasm (HFS), but the procedure is associated with a significant risk of complications such as hearing loss and facial weakness. Many surgeons advocate the use of intraoperative brainstem auditory evoked response (BAER) monitoring in an attempt to improve surgical outcomes. The authors critically assessed a large series of patients with HFS who underwent MVD without neurophysiological monitoring. Methods The authors retrospectively identified 114 consecutive patients, with a history of HFS and without a history of HFS surgery, in whom MVD was performed by a single surgeon without the use of neurophysiological monitoring. Postoperative outcomes were determined by reviewing records and through telephone interviews. At least 1 year of postoperative follow-up data were available for 91 of the 114 patients, and the median follow-up duration in all cases was 8 years (range 3 months–23 years). A Kaplan–Meier analysis showed that 86% of the patients were spasm free at 10 years postoperatively. Results There were no surgical deaths or major deficits, and complications included 1 case of postoperative deafness, 1 of permanent subtotal hearing loss, and 10 of delayed facial palsy, 2 of which did not completely resolve at last follow-up. The outcomes, rates of hearing loss, and other complications compared well with those reported in studies in which investigators used intraoperative monitoring. Conclusions The results suggest that MVD without neurophysiological monitoring is a safe and effective treatment option in patients with HFS. Although BAER monitoring may be a valuable adjunct to surgery at centers experienced with the modality, the absence of intraoperative monitoring should not prevent neurosurgeons from performing MVD in patients with HFS.

Abstract Objectives Microvascular decompression (MVD) for facial nerve remains the highly efficient hemifacial spasm (HFS) treatment. Nonetheless, a variety of cases have poor response to MVD. Using Teflon plus gelatin sponge in MVD seems to be a good solution. No existing study has examined the efficacy of using Teflon combined with gelatin sponge during MVD for HFS. Therefore, this study aimed to compare the efficacy of Teflon combined with gelatin sponge in HFS patients relative to that of Teflon alone. Patients and Methods We retrospectively compared the follow-up results of patients treated with Teflon and gelatin sponge with those treated with Teflon alone previously. Six hundred and eighty-eight primary HFS patients undergoing surgery from January 2010 to January 2018 were retrospectively analyzed. Three hundred and forty-seven cases received simple Teflon, while 342 cases underwent Teflon combined with gelatin sponge. Results In the Teflon plus gelatin sponge group, the incidences of facial palsy and hearing loss at 1 day, 1 year, and 2 years following surgery was significantly lower than those in the simple Teflon group. Differences in the success rates between Teflon plus gelatin sponge and the simple Teflon group were not statistically significant at 1 day, 1 year, and 2 years after surgery. The recurrence rate in the Teflon plus gelatin sponge group was significantly lower at 2 years. Conclusion For HFS patients undergoing MVD, using Teflon plus gelatin sponge can remarkably reduce the incidence of recurrence, facial palsy, and hearing loss compared with those using Teflon alone.

OBJECT Typical hemifacial spasm (HFS) commonly initiates from the orbicularis oculi muscle to the orbicularis oris muscle. Atypical HFS (AHFS) is different from typical HFS, in which the spasm of muscular orbicularis oris is the primary presenting symptom. The objective of this study was to analyze the sites of compression and the effectiveness of microvascular decompression (MVD) for AHFS. METHODS The authors retrospectively analyzed the clinical data for 12 consecutive patients who underwent MVD for AHFS between July 2008 and July 2013. RESULTS Postoperatively, complete remission of facial spasm was found in 10 of the 12 patients, which gradually disappeared after 2 months in 2 patients. No recurrence of spasm was observed during follow-up. Immediate postoperative facial paralysis accompanied by hearing loss occurred in 1 patient and temporary hearing loss with tinnitus in 2. All 3 patients with complications had gradual improvement during the follow-up period. CONCLUSIONS The authors conclude that most cases of AHFS were caused by neurovascular compression on the posterior/rostral side of the facial nerve distal to the root entry zones. MVD is a safe treatment for AHFS, but the incidence of postoperative complications, such as facial paralysis and decrease in hearing, remains high.

Abstract During a 14-month period, 129 individuals underwent 140 operations for microvascular decompression to relieve hemifacial spasm, disabling positional vertigo, tinnitus, or trigeminal neuralgia at our institution. Seven patients were operated upon twice on the same side and 4 were operated upon on both sides at different times. In each case, the brainstem auditory evoked potentials were monitored intraoperatively by the same neurophysiologist. In 75 of these operations, compound action potentials were also recorded from the exposed 8th nerve. Comparison of speech discrimination scores before the operation and at the time fo discharge showed that at discharge, discrimination had decreased in 7 patients by 15% or more and increased in 4 patients by 15% or more, in 2 patients by as much as 52%. Essentially similar results were obtained when preoperative speech discrimination scores were compared with results obtained from the 87 patients who returned for a follow-up visit between 3 and 6 months after discharge. Only one patient lost hearing (during a second operation to relieve hemifacial spasm). Another patient (also operated upon to relieve hemifacial spasm) suffered noticeable hearing loss postoperatively, but had recovered nearly normal hearing by 4 months after the operation. Nine patients had an average elevation of the hearing threshold for pure tones in the speech frequency range (500 to 2000 Hz) of 11 dB or more at 4 to 5 days after the operation; 8 of these had fluid in their middle ears that most likely contributed to the hearing loss. Threshold elevations occurred at 4000 Hz and 8000 Hz in 19 and 29 ears, respectively.

Safe Approach

Microvascular decompression (MVD) is an effective and safe approach for treating hemifacial spasm (HFS). Postoperative complications may include facial nerve palsy, hearing loss, intracerebral haematoma, and brainstem infarction. The occurrence of intracranial cyst following MVD is extremely rare, with few cases documented in the literature. Herein, the cases of two patients with HFS who developed ipsilateral cerebellar cyst following MVD are reported. The first patient was a 50-year-old male presenting with a 6-year history of HFS on the right side of his face. MVD was performed, and 12 days postoperatively he developed dizziness and nausea. Magnetic resonance imaging (MRI) showed a cyst in the ipsilateral cerebellum. Antibiotic treatment provided no benefit, and the cyst was drained. The second patient was a 44-year-old female presenting with a 4-year history of HFS on the right side of her face. MVD was performed, and 18 days following surgery, she developed dizziness and nausea. MRI showed an ipsilateral cerebellar cyst. Conservative treatment was applied and the cyst shrunk. At the 2-month follow-up appointment, symptoms were completely resolved in both patients. Cerebellar cyst is a rare complication following MVD. Timely diagnosis and appropriate treatment should be emphasized, and surgical treatment may be unnecessary.

Three hundred patients with idiopathic hemifacial spasm who underwent microvascular decompression through the retrosigmoid approach are reported. Vascular compression was found in every patient on operation. The results of 1 to 6 years of follow-up show that 276 patients are free of the symptom, 4 patients have markedly diminished spasms and a decreased episode rate, 10 patients have no significant relief from the operation, and 9 have had recurrences of the symptom since the operation. The cure rate in this group is 92%. Complications were sensorineural hearing loss in 13 patients (7 temporary cases, 6 permanent), tinnitus in 7 (4 temporary cases, 3 permanent), temporary postoperative facial weakness in 16, and postoperative meningitis in 10 (9 cases were controlled with antibiotics and 1 patient died).

A 61-year-old man presented with a 1-month history of reduced vision, redness and pain in the right eye. Examination revealed a bandage contact lens (BCL) in situ with diffuse, pigmented deposits. On removal, the underlying cornea was found to be clear. He had been prescribed the BCL 6 months ago following a deep-seated corneal foreign body removal and was unable to follow-up subsequently.The BCL was sent for microbiological and histopathological evaluation. The culture revealed growth of Cladosporium spp, a dematiaceous fungi. Periodic acid–Schiff staining revealed infiltration of pigmented fungal filaments into the substance of the BCL.While contact lens deposits are a frequent finding, fungal deposits are seldom noted. Irregular follow-up and improper lens maintenance are significant risk factors for the same. Early identification and subsequent removal of the lens is vital to prevent infection of the underlying ocular structures.

Abstract Background: Primary trigeminal neuralgia (TN), hemifacial spasm (HFS) and glossopharyngeal neuralgia (GN) are common diseases of nervous system, with similar pathogenesis and treatment strategies. Coexistent of such disease, especially coexistent of TN-HFS-GN simultaneously, is very rare. To date, only nine cases have been reported.Case Presentation: A 70-year-old male with a history of hypertension and diabetes complained of severe involuntary contraction for about 10 years, knife-like and lighting-like pain, which was restricted to the distribution of the second and third branches of trigeminal nerve and pharynx and root of tongue, for about 2 years. Coexistent of TN HFS and GN was diagnosed and MVD was carried out. After MVD, the patient completely free from symptoms and no recurrence and hypoesthesia were recorded in 18 months follow up.Conclusion: Here we report the tenth and oldest male patient with coexistent of TN-HFS-GN. Despite limited reports, MVD is the preferred choice for such diseases which can free patients from spasm and neuralgia.
