AI Article Synopsis

  • First-bite syndrome (FBS) is a rare complication following parapharyngeal space surgery characterized by severe pain in the parotid gland region during the first bite of food, which eases with further chewing.
  • The pain is believed to be caused by sympathetic nerve damage from surgery, leading to increased sensitivity to other nerve impulses.
  • This report documents the third known case of FBS related to carotid endarterectomy, highlighting the need for vascular surgeons to be aware of this potential issue.

Article Abstract

First-bite syndrome (FBS) is an infrequently encountered complication of parapharyngeal space surgery. Patients experience excruciating pain in the ipsiltateral parotid gland region at the first bite of each meal, which improves with subsequent mastication. This is thought to be due to parotid gland sympathetic denervation from surgery with resultant hypersensitivity to parasympathetic impulses. There is no consensus on best treatment for FBS although symptoms tend to improve with time. There are only 2 case reports linking carotid endarterectomy and FBS so far. We report the third case of FBS after carotid endarterectomy to raise awareness among vascular surgeons of the possibility of this complication.
