Treatment of nasal hemangioma: First, surgery. For larger nasal sinus hemangiomas with wide base and easy bleeding, they can be removed through mid-facial debulking surgery, or another extra-nasal route. Pre-operative radiotherapy can reduce intraoperative bleeding, and post-operative radiotherapy can prevent recurrence. Second, laser surgery treatment with local anesthesia can be considered. Simple hemangioma of the nasal cavity is anesthetized with 2%-1% daccaine for 5-10 minutes; polypoid hemangioma of the nasal cavity mass type and cavernous hemangioma are anesthetized with lidocaine plus trace epinephrine for intratumoral injection, and 1% daccaine is also applied for mucosal anesthesia. In maxillary sinus radical surgery for hemangioma, a long needle is used to stab vertically inward at the intersection of the lower edge of the zygomatic arch and the anterior edge of the occlusal muscle, and when it touches the bone wall, it is slightly withdrawn and then advanced inward and upward to the pterygopalatine fossa, at which time the patient will feel the soreness of the ipsilateral maxillary dentition, aspirate without blood, inject lidocaine, and postoperative radiotherapy has the effect of preventing recurrence.
