Hemangioma Involving the Nasal Cavity and Maxillary and Ethmoidal Sinuses
전시영,안승기,황의지,정태지,김형진 대한비과학회 1996 Journal of rhinology Vol.3 No.2
Hemangiomas involving the paranasal sinuses are rare. The tumors are described as well circumscribed, intensely enhancing masses, causing benign-appearing bone changes on CT scans. CT scans show a large, nonhomogenously enhancing mass with remarkable bone erosion, which makes it difficult to differentiate it from malignant epithelial tumors on the basis of the radiologic finings. Medial maxillectomy by a midface degloving procedure or a lateral rhinotomy with lip splitting has been performed for surgical excision. Massive intraoperative bleeding could be avoided by adjunctive preoperative embolization or by intraoperative ligation of the external carotid artery. We report three cases of hemangiomas involving the nasal cavity and the maxillary and ethmoidal sinuses, presenting with refractory epistaxis and easily bleeding, friable intranasal masses.
