Abstract:
Objective To investigate the efficacy and safety of microsurgery for trigeminal neuralgia (TN) in elderly patients.Methods Totally 143 patients with intractable primary TN who received microsurgery were retrospectively analyzed.There were 92 cases in the elderly group with age of 65-82 years,and the other 51 cases in control group with age of 40-62 years.All the patients in both groups were classified as American Society of Anesthesiologists (ASA) Scale Grade 1 to 3.After suboccipital retrosigmoid craniotomy,microvascular decompression (MVD) was performed in 136patients and partial sensory trigeminal rhizotomy in 7 patients.The complications and efficacy were compared between the two groups.Results 87 cases in the elderly group and 49 cases in control group underwent MVD procedure,complete and part pain relief were achieved in 78 cases and 9 cases in the elderly group,45 cases and 4 cases in control group,respectively.After an average follow-up period of 2.6 and 2.1 years,4 cases (5.1％) among 79 follow-up cases and 3 cases (6.5％) among 46follow-up cases experienced TN recurrences in the elderly and control groups,respectively.No statistically significant differences existed in the efficacy and recurrence rate between the two groups (P＞0.05).There were 3 cases with aseptic meningitis,1 cases with hearing decrease,1 case with cerebrospinal fluid leakage,1 case with pulmonary infection and 1 cases with deliration in the elderlygroup,meanwhile,1 cases with aseptic meningitis,1 case with tinnitus and 1 case with cerebrospinal fluid leakage after surgery in control group (P＞0.05).No facial hypoesthesia appeared in the patients receiving MVD.5 cases in the elderly and 2 cases in control group underwent partial trigeminal rhizotomy with facial hypoesthesia,but the pain released,and no recurrence was found.There were no dead cases in both groups.Conclusions With cautious and proper treatment,microsurgical procedure can be performed safely and effectively in the elderly TN.
