Abstract: Objective To explore the surgical techniques of neuroendoscopic microvascular decompression for hemifacial spasm through retrosigmoid key hole approach. Methods A total of 31 patients with hemifacial spasm were selected based on clinical symptoms and conditions after drug use. Then neuroendoscopic microvascular decompression through retrosigmoid key hole approach was performed. Results After surgery, pain disappeared in 24 (77.4%) and reduced in 6 patients (19.4%), while 1 patient (3.2%) showed no obvious amelioration. Postoperative complications included mild facial parelysis in 3 cases (9.68%), hearing loss in 2 cases (6.45%), headache with frequent nausea and vomiting in 1 case (3.23%), and fever in 2 cases (6.45%). No postoperative bleeding, cerebellum contusion, leakage of cerebrospinal fluid or blade poor healing were observed. Conclusion Neuroendoscopic microvascular decompression through retrosigmoid key hole approach is a novel, effective and minimally invasive way to treat hemifacial spasm.

Key words: Microvascular decompression, Neuroendoscopic, Retrosigmoid key hole approach, Hemifacial spasm
