Abstract
We report three cases of first bite syndrome (PBS) after parotid surgery. The interval between surgery and the PBS episode differed in each case. The symptoms of PBS did not disappear or change. The tumors were located in or adjacent to the deep layer of the inferior pole of the parotid gland, and surgery was not performed in the parapharyngeal space, except in one case. The external carotid artery, superficial temporal artery and retromandibular vein were exposed at parotid surgery in all three cases. Although these vessels were generally not ligated, PBS appeared. Therefore, it is necessary to explain first bite syndrome even to patients whose external carotid artery, superficial temporal artery and retromandibular vein will be exposed during surgery for a parotid tumor in the deep layer of the inferior pole of the parotid gland.
