Baroreflex dysfunction after nasopharyngectomy and bilateral carotid isolation.

Baroreflex dysfunction (BRD) is an uncommon but perplexing clinical entity that occurs after an operation performed in the head and neck. Cases of BRD have occasionally been reported after bilateral carotid endarterectomies and in rare brain-stem tumors. We describe, for the first time to our knowledge, BRD in a patient after nasopharyngectomy and bilateral carotid isolation for recurrent nasopharyngeal carcinoma.
