Transnasal endoscopic surgery for vascular tumors of the nasal cavity. Case report

Background. Cavernous hemangioma of the ethmoidal labyrinth is a vascular malformation, and its removal can lead to intense bleeding from both the anterior and posterior ethmoidal arteries feeding it. In this regard, there are several methods of early surgical devascularization of the tumor, one of which is the transcaruncular approach with the imposition of titanium clips on the anterior and posterior ethmoid arteries, followed by transnasal endoscopic removal of the tumor. Description of the clinical case. The results of surgical treatment of a patient with cavernous hemangioma of the left ethmoidal labyrinth are presented. At the first stage, early devascularization of the tumor by clipping the anterior and posterior ethmoidal arteries through the transcaruncular endoscopic approach was performed, and at the second stage - transnasal endoscopic removal of the cavernous hemangioma. Results. Transorbital endoscopic clipping of ethmoidal arteries made it possible to significantly reduce the intensity of blood flow in the tumor tissue and to perform endoscopic transnasal tumor resection with minimal blood loss. Intraoperative blood loss was 100 ml. There were no complications. Conclusion. Transorbital endoscopic clipping of the anterior and posterior ethmoid arteries is an effective and safe method for early devascularization of cranio-orbital tumors. The technique is promising and requires further development.
