Abstract

Hemangiomas are benign neoplasms, common in the head and neck region, but very infrequent in the paranasal sinuses. They grow slowly and can be locally destructive due to the pressure exerted on the bone. These characteristics make them difficult to differentiate from malignant tumors originating in paranasal sinuses. The main treatment of paranasal sinus hemangiomas in adults is surgery, being the transnasal approach with endoscopes alone or combined with an external approach the most used. Methods We analyzed the clinical histories of all adult patients who underwent an endonasal approach with endoscopes, for having hemangiomas of the nasal cavity and paranasal sinuses in the Italian Hospital of Buenos Aires, between June 2006 and December 2016. We excluded patients with hemangiomas who were less than 18 years old, with small tumors (less than 2 cm), vascular malformations, and those who underwent surgical procedures performed externally. All were studied by nasal endoscopy, computed tomography and magnetic resonance with contrast. The surgeries were performed under general anesthesia, with endoscopes of 0° and 30°, conventional surgical instruments were used for rhinosinusal endoscopic surgery. By endonasal approach a maxillary antrostomy, ethmoidectomy, and a middle turbinate resection were performed, and the tumor was resected. In another patient, the sphenopalatine artery was also cauterized, and a sphenoidotomy was performed, and in the remaining
