Interventional treatment of nasopharyngeal hemangioma

Fibrovascular tumors of the nasopharynx are common benign tumors of the nasopharynx, prevalent in male adolescents aged 10-25 years. Pathologically, the tumor consists of vascular spaces of various shapes and sizes surrounded by a fibrous tissue matrix. Clinical manifestations:Nasal bleeding, nasal obstruction, breathing through the mouth, nasal sound, snoring, accumulation of nasal secretions, tinnitus, hard of hearing, headache, abnormal changes in the eyes. According to the size of the tumor, the traditional surgical treatment method is to remove the tumor through the palatal incision approach or the non-incision approach through the pharyngeal isthmus. For huge tumors invading the intracranium, combined intracranial and extracranial routes can be used for surgery. Preoperative anesthetic intubation/tracheotomy should be performed to maintain airway patency. Ligation of the ipsilateral external carotid artery should be performed 1 d before surgery or on the day of surgery. Adequate preoperative preparations for fluid and blood transfusion should be made, and cryoanesthesia and hypotensive anesthesia can be used to reduce bleeding. Interventional therapy:DSA vascular embolization method, for nasopharyngeal fibroangioma has the role of diagnosis and preoperative preliminary treatment. It has the advantages of accuracy, safety and rapidity than traditional vascular ligation, especially for unexplained hemorrhage in the nasopharynx of the posterior nostril, which has the role of definite diagnosis and treatment. Performing external carotid arteriography with gelatin sponge embolization before surgical resection significantly reduces intraoperative bleeding. For patients who do not want to undergo surgery, the choice of permanent embolic agent or spring coil embolization treatment can also receive good results.
