Abstract

Objective To investigate the treatment measures of difficult decompression in facial nerve microvascular decompression and its effect. Methods The clinical data of 31 patients with difficult decompression who underwent facial nerve microvascular decompression in Beijing Municipal Corps Hospital of Chinese People’s Armed Police Force from January 2019 to October 2023 were retrospectively analyzed. The types of difficult decompression such as intraoperative encephalocele, severe arachnoid adhesions and complex responsible blood vessels, were targeted and the surgical effects were observed. Results The symptoms of hemifacial spasm disappeared completely in 20 patients (66.66%), which was a complete remission. Seven patients (22.58%) still had facial spasm symptoms of varying degrees, which were partially relieved. Four cases (13.33%) had no change in symptoms. After 6 months of follow-up, 3 patients still had mild facial tics, which was significantly relieved than before surgery, and the overall cure rate was 90.33%. Conclusions In the case of difficult decompression during facial nerve microvascular decompression, a good surgical effect can be obtained through careful preoperative evaluation and flexible and diverse intraoperative difficult decompression measures.
