BACKGROUND: Carotid body paragangliomas are rare and therapeutically challenging. Shamblin I or II carotid body paraganglioma can be removed en bloc. This operation is sometimes combined with preoperative transarterial embolization to control bleeding. However, Shamblin III carotid body paraganglioma, which is encased with carotid vessels, is difficult to remove without carotid artery ligation for excision. Sometimes, not all tumor tissues are removed during operation and residual tumor tissues remain. Here, we review a case of Shamblin III carotid body paraganglioma removal without preoperative transarterial embolization or ligation of the carotid artery. We present a successful technique for Shamblin III carotid body paraganglioma resection that reduces bleeding during the operation. MATERIAL AND METHODS: A 74-year-old male patient who had an enlarged left neck mass for more than 20 years underwent tumor excision. The final pathology was carotid body paraganglioma. During the operation, the tumor was discovered to be encased in the bifurcation of the common carotid artery. We carefully isolated and temporarily clamped the common carotid artery to enable application of the finger dissection method to completely free the tumor from the carotid artery in a safe and bloodless plane. RESULTS: Neither intraoperative massive bleeding nor postoperative cranial nerve deficit occurred. Favorable wound status was noted during outpatient department follow-up. CONCLUSIONS: We describe a successful case of Shamblin III carotid body paraganglioma removal using temporary clamping of the common carotid artery and the finger dissection method.
