ABSTRACT
Objective: To improve the results of surgical treatment of patients with cranioorbital tumors. For this purpose, for patient with high vascularized tumor of ethmoidal bone, adjacent to the medial wall of the orbit, early devascularization as the first stage and transnasal endoscopic removal of the tumor as the second stage was performed. Tumor devascularization was performed by clipping of anterior and posterior ethmoidal arteries through a transcaruncular endoscopic approach. For this, the incision of the conjunctiva, after infiltration with local anesthetics, was carried out posteriorly from the lacrimal caruncle, continuing it above and below the posterior border of the medial canthal ligament. Then, after dissection of the periosteum posterior to the posterior lacrimal crest, further stages of the surgical intervention are performed under the control of an endoscope with a viewing angle of 0°. Results. Transorbital endoscopic clipping of the ethmoid arteries allowed to significantly reduce the intensity of blood flow in the tumor tissue and perform endoscopic transnasal removal of the tumor with minimal blood loss. Intraoperative blood loss was 100 ml. No complications were recorded. Conclusion. Transorbital endoscopic clipping of the anterior and posterior ethmoidal arteries is an effective and safe method for early devascularization of partially embolized or non-embolized cranioorbital tumors. The technique is promising and requires further development.
