Surgical management for glossopharyngeal neuralgia associated with cardiac syncope: two case reports

Abstract

Two patients with glossopharyngeal neuralgia associated with cardiac syncope were treated with temporary cardiac pacemakers for cardiac syncope and then microvascular decompression. The offending arteries were the posterior inferior cerebellar artery in one patient and the anterior inferior cerebellar artery in the other. The offending arteries were attached to the glossopharyngeal nerve and the vagal nerve at the root entry zones. After surgery, the patients were free from neuralgia and cardiac syncope did not occur after the pacemakers were extracted. Implantation of a temporary cardiac pacemaker in the perioperative period ensures safe microvascular decompression.

Key words:

• Cardiac syncope
• glossopharyngeal neuralgia
• microvascular decompression
