The treatment of odontogenic mucinous tumor generally chooses complete surgical excision, because it is easy to recur, marginal excision should be performed as follows. 1. Odontogenic mucinous tumor is not sensitive to radiation, and it is mainly treated by complete surgical excision. Since the tumor has no peritoneum and shows local infiltrative growth, if the surgical resection is not complete, it is easy to cause tumor recurrence, usually marginal resection is needed, which usually requires osteotomy at 0.5~1.0cm of normal bone outside the tumor. 2. If the tumor is large, half of the mandible or maxilla should be resected to prevent recurrence, and bone grafting can be done at the same time in the bone defect area. It is recommended to go to regular medical institutions in time for early professional treatment with the help of doctors.
