Papers of particular interest, published recently, have been highlighted as: Patients often improve gradually over time, but symptomatic treatment with botulinum toxin or neuropathic medicine may be required. To help with this, we have proposed diagnostic criteria for clinical assessment. It is critical for clinicians to be able to differentiate first bite syndrome from other paroxysmal facial pain. Evidence regarding treatment is limited to case reports/series, however, botulinum toxin injections and neuropathic medicines have been helpful in select cases. It is common for patients to present with concurrent great auricular neuropathy and/or Horner’s syndrome. This is seen most typically in the post-surgical setting following surgery in the parotid or parapharyngeal region, but neoplastic etiologies have also been reported. Pathophysiology has been attributed to imbalanced sympathetic/parasympathetic innervation of the parotid gland. Recent Findingsįirst bite syndrome is severe sharp or cramping pain in the parotid region occurring with the first bite of each meal and improving with subsequent bites. This paper will highlight the clinical features and relevant anatomy of first bite syndrome, with the goal of helping clinicians differentiate this from other similar facial pain disorders. The pain did not recur 2.5 years after cessation of treatment.Though first bite syndrome is well known in surgical settings, it is not commonly included in the differential for sharp paroxysmal facial pain in the neurology literature. The pain completely disappeared after 16 repeats of SGB. The pain did not change after 5 repeats of SGB however, the pain after the first bite decreased after 6 repeats of SGB. He rated the first bite pain 80 and the pain after the first bite 100 on a visual analog scale of 100. He received enteral alimentation and diclofenac. Medications did not decrease the pain and the pain was so severe that the patient could not have any food. Pain in the right parotid gland region developed 6 months before he was referred to us. He did not have any surgery done on the right parapharyngeal area. A man aged in his thirties had 6-month history of pain in the parotid gland region that occurred immediately after the first bite of every meal. We report patient with long-standing idiopathic FBS whose pain disappeared after repeated stellate ganglion blocks (SGB). First bite syndrome (FBS) is a rare disease causative of pain in the parotid gland region at the first bite of each meal.
