ABSTRACT

OBJECTIVE To investigate the clinical features and therapeutic methods of ameloblastoma in nasal cavity and paranasal sinuses. METHODS The clinical data of 6 cases of ameloblastoma in nasal cavity and paranasal sinuses diagnosed by pathology were analyzed retrospectively, and the relevant literature were reviewed. RESULTS All of the 6 cases received surgical treatment. The follow-up period was 15 months to 10 years after operation.3 patients recurred until the last follow up. Among them, 2 cases recurred once, 1 case recurred 2 times, no patient died of this tumor. CONCLUSION The incidence of ameloblastoma in nasal cavity and paranasal sinuses is low and the symptoms are nonspecific, the diagnosis mainly depends on pathology and immunohistochemistry. CT and MRI examinations of ameloblastoma are helpful in diagnosis and differential diagnosis of the lesion. The main treatment is surgical resection of the lesion, the recurrence rate is higher. It has malignant tendency, and long-term follow-up is needed.
