Abstract To explore the causes of persistent abnormal muscle response (AMR) after microvascular decompression (MVD) for hemifacial spasm (HFS) and the clinical outcomes of these patients. MVDs performed in Nanjing Drum Tower Hospital in 2017 were retrospectively studied, and 326 patients with HFS were classified into two groups based on whether AMR disappeared or persisted following MVD. The clinical features, treatment efficacy and postoperative complications were compared between the two groups. 305 patients with disappeared AMR after decompression were classified as Group A. In Group B, the 21 patients exhibited persistent AMR after successful MVD. The preoperative duration of symptoms in Group B was significantly longer than that in Group A (P < 0.001), and no significant difference was identified between the two groups in terms of gender, side, age and offending vessels (P > 0.05). The immediate postoperative cure rate of Group A (88.9%)was significantly higher than that in Group B (28.6%, P < 0.001), furthermore, the two groups were not different in the long-term outcome and the incidence of surgical complications (P > 0.05). The long preoperative duration of HFS patients may account for persistent AMR after successful decompression, and it is more likely for these patients to get delayed cured, the long-term outcomes showed no difference compared to those in patients with disappeared AMR after MVD.

Abstract OBJECTIVE Multiple studies have proved that microvascular decompression (MVD) is the treatment of choice in cases of medically refractory trigeminal neuralgia (TN). In the elderly, however, the surgical risks related to MVD are assumed to be unacceptably high and various alternative therapies have been proposed. We evaluated the outcomes of MVD in patients aged older than 65 years of age and compared them with the outcomes in a matched group of younger patients. The focus was on procedure-related morbidity rate and long-term outcome. METHODS This was a retrospective study of 112 patients with TN operated on consecutively over 22 years. The main outcome measures were immediate and long-term postoperative pain relief and neurological status, especially function of trigeminal, facial, and cochlear nerves, as well as surgical complications. A questionnaire was used to assess long-term outcome: pain relief, duration of a pain-free period, need for pain medications, time to recurrence, pain severity, and need for additional treatment. RESULTS The mean age was 70.35 years. The second and third branches of the trigeminal nerve were most frequently affected (37.3%). The mean follow-up period was 90 months (range, 48–295 months). Seventy-five percent of the patients were completely pain free, 11% were never pain free, and 14% experienced recurrences. No statistically significant differences existed in the outcome between the younger and older patient groups. Postoperative morbidity included trigeminal hypesthesia in 6.25%, hypacusis in 5.4%, and complete hearing loss, vertigo, and partial facial nerve palsy in 0.89% each. Cerebrospinal fluid leak and meningitis occurred in 1 patient each. There were no mortalities in both groups. CONCLUSION MVD for TN is a safe procedure even in the elderly. The risk of serious morbidity or mortality is similar to that in younger patients. Furthermore, no significant differences in short- and long-term outcome were found. Thus, MVD is the treatment of choice in patients with medically refractory TN, unless their general condition prohibits it.

Abstract INTRODUCTION Microvascular decompression (MVD) is an effective and durable treatment for patients with trigeminal neuralgia (TN) due to neurovascular compression (NVC). In the absence of NVC, the traditional MVD is less effective in achieving long-term pain relief. Internal neurolysis at the root entry zone (REZ) of the trigeminal nerve has been described in the literature; however, there are few reports of long-term outcome after this procedure. Furthermore, this is the first study to combine this procedure with additional partial neurectomy. METHODS This is a retrospective review of the senior author's patients with TN who underwent retrosigmoid craniectomy for MVD with internal neurolysis and partial neurectomy. Primary indications were patients with TN and no evidence of NVC intraoperatively. A total of 9 patients were included in the analysis. Three cases were of recurrent TN. The technique was performed with an 11-blade or arachnoid knife to open the perineurium in a longitudinal fashion at the REZ. A disc dissector was used to comb the fascicles along the longitudinal course, and a partial neurectomy was performed with a microscissors to make three selective cuts into the fascicles at the REZ. Barrow Neurological Institute (BNI) facial pain and numbness scales were used as postoperative assessment. RESULTS At median follow up of 12 mo (range: 2 to 34), 8 of 9 patients (89%) had a BNI-pain score of I (no trigeminal pain, no medications). Two of nine patients (22%) had a BNI-numbness score of I (no numbness); seven (78%) had a BNI-numbness score of II (mild facial numbness that is not bothersome). CONCLUSION Internal neurolysis with partial neurectomy appears to be an effective and potentially durable treatment option for patients with TN (primary or recurrent) without NVC. Larger series with longer follow-up is indicated to further evaluate the utility of this procedure.
