Treatment of nasal hemangioma: First, surgery: the base of the tumor and the attached cartilage membrane should be removed during surgery to prevent recurrence; for larger nasal sinus hemangiomas with a wider 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 can be considered for treatment with local anesthesia: simple hemangioma of the nasal cavity is anesthetized with 2%-1% dacaine for 5-10 minutes; polypoid hemangioma of the nasal cavity and cavernous hemangioma are anesthetized with lidocaine plus trace epinephrine for intratumoral injection, and 1% dacaine 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of the zygomatic arch and the anterior edge of the occlusal muscle, and when it touches the bone wall, it is slightly withdrawn and then advanced inward and upward to the pterygopalatine fossa, at which time the patient will feel the soreness of the ipsilateral maxillary dentition,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.
