We report three cases of recurrent oral cancer with carotid blowout syndrome (CBS). In case 1, the recurrent tumor reduced in size during chemoradiotherapy. As a result, the external carotid artery was exposed in the oral cavity and ruptured. The patient was treated via embolization in the external carotid artery. In case 2, the recurrent tumor markedly reduced in size during chemotherapy, resulting in exposure of the internal carotid artery in the skin fistula posterior to the auricle. The exposed artery was prophylactically treated by embolization. In case 3, the internal carotid artery was ruptured due to recurrent tumor invasion and wound infection. The patient presented massive hemorrhage and was treated with stent placement on an emergency basis. The surgical site was covered by a pectoralis major myocutaneous flap. The frequency of treatment for progressive and recurrent oral cancers has been increasing due to progress in medical technology and chemotherapy. A multidisciplinary team approach should always be available for emergencies, including potentially fatal complications such as carotid system hemorrhage.
