Object. Microvascular decompression (MVD) has become one of the primary treatments for typical trigeminal neuralgia (TN). Not all patients with facial pain, however, suffer from the typical form of this disease; many patients who present for surgical intervention actually have atypical TN. The authors compare the results of MVD performed for typical and atypical TN at their institution. Methods. The results of 2675 MVDs in 2264 patients were reviewed using information obtained from the department database. The authors examined immediate postoperative relief in 2003 patients with typical and 672 with atypical TN, and long-term follow-up results in patients for whom more than 5 years of follow-up data were available (969 with typical and 219 with atypical TN). Outcomes were divided into three categories: excellent, pain relief without medication; good, mild or intermittent pain controlled with low-dose medication; and poor, no or poor pain relief with large amounts of medication. The results for typical and atypical TN were compared and patient history and pain characteristics were evaluated for possible predictive factors. Conclusions. In this study, MVD for typical TN resulted in complete postoperative pain relief in 80% of patients, compared with 47% with complete relief in those with atypical TN. Significant pain relief was achieved after 97% of MVDs in patients with typical TN and after 87% of these procedures for atypical TN. When patients were followed for more than 5 years, the long-term pain relief after MVD for those with typical TN was excellent in 73% and good in an additional 7%, for an overall significant pain relief in 80% of patients. In contrast, following MVD for atypical TN, the long-term results were excellent in only 35% of cases and good in an additional 16%, for overall significant pain relief in only 51%. Memorable onset and trigger points were predictive of better postoperative pain relief in both atypical and typical TN. Preoperative sensory loss was a negative predictor for good long-term results following MVD for atypical TN.

Abstract BACKGROUND Trigeminal neuralgia (TN) refractory to medical management is often treated with microvascular decompression (MVD) involving the intracranial placement of Teflon. The placement of Teflon is an effective treatment, but does apply distributed pressure to the nerve and has been associated with pain recurrence. OBJECTIVE To report the rate of postoperative pain recurrence in TN patients who underwent MVD surgery using a transposition technique with fibrin glue without Teflon. METHODS Patients were eligible for our study if they were diagnosed with TN, did not have multiple sclerosis, and had an offending vessel that was identified and transposed with fibrin glue at our institution. All eligible patients were given a follow-up survey. We used a Kaplan-Meier (KM) model to estimate overall pain recurrence. RESULTS A total of 102 patients met inclusion criteria, of which 85 (83%) responded to our survey. Overall, 76 (89.4%) participants responded as having no pain recurrence. Approximately 1-yr pain-free KM estimates were 94.1% (n = 83), 5-yr pain-free KM estimates were 94.1% (n = 53), and 10-yr pain-free KM estimates were 83.0% (n = 23). CONCLUSION Treatment for TN with an MVD transposition technique using fibrin glue may avoid some cases of pain recurrence. The percentage of patients in our cohort who remained pain free at a maximum of 17 yr follow-up is on the high end of pain-free rates reported by MVD studies using Teflon. These results indicate that a transposition technique that emphasizes removing any compression near the trigeminal nerve root provides long-term pain-free rates for patients with TN.

Object. Brachycephaly is a characteristic feature of Apert syndrome. Traditional techniques of cranioplasty often fail to produce an acceptable morphological outcome in patients with this condition. In 1996 a new surgical procedure called “dynamic cranioplasty for brachycephaly” (DCB) was reported. The purpose of the present study was to analyze perioperative data and morphological long-term results in patients with the cranial vault deformity of Apert syndrome who were treated with DCB. Methods. Twelve patients have undergone surgery performed using this technique since its introduction in 1991 (mean duration of follow-up review 60.2 months). Eleven patients had bicoronal synostosis and one had a combined bicoronal—bilambdoid synostosis. Perioperative data and long-term evolution of skull shape visualized on serial cephalometric radiographs were analyzed and compared with normative data. Changes in mean skull proportions were evaluated using a two-tailed paired-samples t-test, with differences being considered significant for probability values less than 0.01. The mean operative blood transfusion was 136% of estimated red cell mass (ERCM) and the mean postoperative transfusion was 48% of ERCM. The mean operative time was 218 minutes. The duration of stay in the intensive care unit averaged 1.7 days and the mean hospital stay was 11.8 days. There were no incidences of mortality and few complications. An improvement in skull shape was achieved in all cases, with a change in the mean cephalic index from a preoperative value of 90 to a postoperative value of 78 (p = 0.000254). Conclusions. Dynamic cranioplasty for brachycephaly is a safe procedure, yielding high-quality morphological results in the treatment of brachycephaly in patients with Apert syndrome.

✓ The authors present the case of a 47-year-old man who, after undergoing microvascular decompression for trigeminal neuralgia, experienced symptomatic pain relief but developed prolonged aseptic meningitis. This case is unusual in that the patient remained dependent on steroid medications for nearly 5 months following the initial surgery and the aseptic meningitis did not resolve until after surgical removal of the Teflon used to pad the trigeminal nerve. The pathophysiological characteristics of the body's reaction to implanted Teflon are discussed along with the rationale for removing this substance in cases of prolonged intractable aseptic meningitis.

✓ This series of 228 patients with infantile non-neoplastic hydrocephalus who received either a ventriculoatrial (VA) or a ventriculoperitoneal (VP) shunt before 2 years of age was followed for an average of 7 years, and the results with the two types of shunt were compared. Mortality and infection rates were similar for both groups of patients, but children with VP shunts required significantly fewer revisions and had a much greater likelihood of not having any revisions during the follow-up period. Late complications occurred more frequently with VA shunts and were more serious. It is concluded that VP shunts offer significant advantages over VA systems in this population.

✓ The authors report the long-term results of stereotactic surgery for severe posttraumatic appendicular tremor in 35 patients. The tremors developed after severe head trauma in 33 patients (94%) and after mild to moderate head trauma in two (6%). In all but one, the tremor was most evident during activity. The amplitude of the kinetic tremor was greater than 5 cm in 33 patients (94%) and greater than 12 cm in 19 patients (54%). All were severely incapacitated in their daily living activities due to the tremors. The 35 patients underwent 42 stereotactic operations; five patients were reoperated on the same side and two were treated with a bilateral staged procedure. The contralateral zona incerta was the stereotactic target in 12 patients and was targeted in combination with the base of the ventrolateral (oroventral) thalamus in 23 patients. Long-term postoperative follow-up review was obtained in 32 patients (mean follow-up period 10.5 years). Persistent improvement of tremor was noted in 88%. The tremor was absent or markedly reduced in 65%. Functional disability was assessed and quantified with a modified form of an established rating scale for patients with tremor; it was reduced from a mean value of 57% of maximum disability to 37% over the long term (p < 0.001). Follow-up lesion assessment was obtained in 18 patients by multiplanar magnetic resonance imaging and at autopsy in one patient whose death was unrelated to surgery. As in previous studies, the frequency of persistent side effects was relatively high (38%). These consisted mainly of aggravation of preoperative symptoms. The results are compared to those of a total of 55 patients reported from 1960 to 1992. The occurrence of dystonia and dystonic postures is discussed. Stereotactic surgery is a powerful tool to alleviate posttraumatic tremor and to improve functional disability. However, as there is considerable risk of persistent morbidity in patients after severe head trauma, the operation should be restricted to selected cases with disabling tremor.

Idiopathic Trigeminal Neuralgia

Abstract Background. We aimed to present the immediate and long term effect of percutaneous balloon compression (PBC) for idiopathic trigeminal neuralgia (ITN). Methods. ITN patients who underwent PBC for the first time in the past seven years were enrolled. Base line data and immediate postoperative outcomes were collected by reviewing the medical records and long term results. Kaplan-Meier curve, life-table analysis proportional-hazards analysis were utilized to assess the long term results and the likelihood of tic recurrence. Results. 12,797 patients were enrolled. Immediate after the PBC procedure, complete and partial pain relief were achieved in 95.6% and 1.1% patients respectively, with no relief in 1.7 % patients; the common side effects on the affected side of face included the sense loss in 98.9% patients, with 3.8% of them experienced sense loss combined abnormal sense; masseter weakness in 90.6%, herpes eruption in 51.4%, corneal reflex weakness or loss in 12.7% patients. The fewer perioperative complications covered diplopia in 139 patients (1.1%), partial hearing loss in 190 patients (1.5%), vascular complications in 5 patients (0.05%), brainstem hematoma in one patient (0.01%), ischemic stroke in two patients (0.02%), intracranial hemorrhage in 11 patents (0.09%), and intracranial infection in one patient (0.01%) patients. Of three deaths happened in the perioperative period, two died of intracranial hemorrhage, and the other one died of intracranial infection. 5794 (49.2%) patients, who were followed than one year after the procedure, were included in the follow-up study, with the median follow-up period of 7.2 years. Complete and partial pain relief were obtained in 82.9% and 6.8% patients respectively, while the pain recurrence occurred in 8.5% patients. Side effects included sense loss without abnormal sense in 54.3%, with acceptable abnormal sense in 6.0%, and with severe abnormal sense in 2.0% patients. Masseter weakness was reported by 7.5% patients. 96.4% patients were satisfied with the procedure. Conclusion. Our study shows PBC is a safe, simple and effective procedure, with both immediate and long-term success rates, acceptable side effects and fewer deadly complications, should be considered as one of the best choice for the treatment of ITN patients.

Object. The authors tested the hypothesis that two targets are needed to treat postherpetic trigeminal neuralgia (TN): one in the trigeminal nerve for the direct sharp pain and one in the thalamus for the diffuse burning pain. Methods. Three patients with refractory postherpetic TN were treated with gamma knife surgery (GKS) through a novel two-target approach. In a single treatment session, both the trigeminal nerve and centromedian nucleus were targeted. First, the trigeminal nerve, ipsilateral to the facial pain, was treated with 60 to 80 Gy. Second, the centromedian nucleus was localized using standard coordinates and by comparing magnetic resonance images with a stereotactic atlas. A single dose of 120 to 140 Gy was delivered to the target point with a single 4-mm isocenter. Patients were followed clinically and with neuroimaging studies. Pain relief was scored as excellent (75–100%), good (50–75%), poor (25–50%), or none (0–25%). Follow up ranged from 6 to 53 months. There were no GKS-related complications. Two patients died of unrelated medical illnesses but had good or excellent pain relief until death. One patient continues to survive with 44 months follow up and no decrease in pain intensity, but with a decreased area of pain. Conclusions. Combined GKS of the centromedian nucleus and trigeminal nerve in a single treatment session is feasible and safe, and the effect was promising. A larger study is required to confirm and expand these results.

✓ This long-term prospective study evaluates the clinical results of subsequent laminectomy in 103 consecutive patients who initially underwent chemonucleolysis (CNL) or laminectomy for lumbar disc herniation. Between 1981 and 1994, 53 patients who had received CNL initially and then underwent laminectomy and 50 patients treated initially with laminectomy underwent a repeat laminectomy. Clinical assessment at 6 weeks showed a success rate of 80.8% for post-CNL laminectomy and 78% for repeat laminectomy. At 6 months, the success rate for patients treated with CNL was 86% versus 78.7% for laminectomy. At 12 months, the overall success rate for the CNL group was 80.4% versus 83.3% for the laminectomy group, but in patients who had not obtained relief from the first procedure the success rate for the second procedure was higher for the post-CNL patients. A questionnaire was sent to all patients for 1- to 13-year follow-up review. The average follow-up period was 6.6 years for post-CNL laminectomy and 5.2 years for repeat laminectomy. The long-term success rate (81.8%) was higher in the post-CNL group compared to 64.4% in the repeat laminectomy group. Seven patients in the post-CNL group and nine in the repeat laminectomy group had undergone a third operation. When these originally successfully treated patients were reassigned after unsuccessful outcomes, the success rate for the CNL groups was 72.7%, versus 51.1% in the laminectomy group (p = 0.049). Employment rates were 80% for patients with CNL (21.8% changed jobs) and 76.3% for patients undergoing laminectomy (48.3% changed jobs) (p = 0.036). In conclusion, patients who underwent laminectomies after receiving CNL had significantly better long-term results than those who had repeat laminectomies.
