Hemangioma of the nasal cavity and paranasal sinuses. Description of a clinical case

Background. Hemangiomas are classified as hamartomas, representing an anomalous proliferation of endothelium-lined vessels. Zygomatic and nasal bone hemangiomas are quite rare. Localized in the nasal cavity and paranasal sinuses,
hemangioma arises from soft tissues, but in the future it can cause bone destruction of the surrounding tissues and manifests itself, as a rule, in the form of recurrent nosebleeds, hemoptysis and difficulty in nasal breathing. Non-radical
removal of a tumor-like formation leads to recurrence, therefore, the main method of treating hemangiomas, especially deep ones, is surgical excision with preoperative embolization to reduce intraoperative bleeding.
Case description. Patient S., 65 years old, was admitted with complaints of difficulty in nasal breathing, more  on the right, pulling pain in the formation of the back and slope of the nose, headache, deformity of the external nose.
A biopsy of the formation of the nasal cavity was performed, according to which: arteriovenous hemangioma of the anterior cells of the ethmoid labyrinth on the right, the right half of the nose, extending into the soft tissues of the external nose,
the adjacent basal parts of both frontal sinuses. In order to prevent bleeding, before removing the vascular formation, CT angiography was performed followed by selective embolization of the right maxillary artery that feeds it. The vascular
anomaly was surgically removed and a bone defect plasty was performed.
Outcomes. A 65-year-old patient successfully underwent surgical treatment of hemangioma of the nasal cavity and paranasal sinuses, with preliminary embolization of adductor vessels by radical excision of arteriovenous malformation, followed by bone defect plasty with a titanium plate. There were no complications in the postoperative period.
