【Abstract】 Objective To find out the incidence rule, the clinical features and the diagnostic points of odontogenic myxoma, so that the level of diagnosis and treatment would be improved. Methods 23 cases from Jan.1982～Dec.2000 were reviewed. All the cases were identified through pathological examination. Results Of the 23 cases, the sex ratio was 1∶ 1.5 . The group of 20～29 and 40～49 year old had high incidence, and the mandible had a predilection(78%). The clinical symptom was continuous enlargement of the jaw. Only 3 cases were diagnosed correctly preoperatively. The accuracy was 13%. Complete removal and immediate reconstruction were regarded as the rule of the treatment. Conclusion Odontogenic myxoma is not common. The low accuracy of the diagnosis is related with lacking of characteristic symptom. Radiograph and pathological examination aid to diagnosis. Because of its invasive nature, relapse will occur after conservative treatment. Also, the follow up is necessary.更多还原
