Abstract

Abstract: PURPOSE: To analyze the clinical pathological and prognosis factors of head and neck odontogenic myxoma. METHODS: A retrospective study was adapted for patients who received surgery in the Department of Oromaxillofacial Head and Neck Oncology, Shanghai Ninth People's Hospital from 2001-2017. Clinical, pathological and prognosis data were collected and analyzed with SPSS 17.0 software package. RESULTS: Seventy-nine patients were finally selected, 71 could be followed up. Among 71 patients, 30 were male; 27 were ≤30 years, 39 were within 31-60 years. Twelve had smoking history, 3 had alcoholism history. Forty-two had tumor in mandible, 26 had tumor in the maxilla and skull base. The median of the largest diameter tumor was 3.5 cm, 36 were ≤3.5 cm. Sixty received block resection, 11 underwent curettage. Fifty-two were rich in fibrous content while 19 were rich in mucus content. Four had local recurrence within follow-up period. Patients receiving curettage had higher rate of local recurrence (36.36%) compared while those with block resection (P=0.001). CONCLUSIONS: Head and neck odontogenic myxoma was a kind of benign tumor with local recurrence, mostly located in the mandible and high incidence in patients within 31-60 years old. Block resection can provide good control of local recurrence compared with curettage.
