Background This retrospective study investigated the reduction rate and speed of shrinkage after marsupialization in mandibular cystic ameloblastoma and clarified whether marsupialization is appropriate for unicystic ameloblastoma and multicystic ameloblastoma. Methods Sixty‐three patients with mandibular cystic ameloblastoma were initially treated with marsupialization. Premarsupialization and postmarsupialization panoramic radiographs were reviewed for reduction rate and speed of shrinkage, and then were evaluated with age, sex, tumor location, and tumor type. Results The overall recurrence rate was 4.5% (2/44). The average reduction rate after marsupialization was 65.6%. No significant difference was found between unicystic ameloblastoma and multicystic ameloblastoma in reduction rate. The speed of shrinkage of unicystic ameloblastoma was significantly faster than that of multicystic ameloblastoma ( P < .05). Similarly, patients with multicystic ameloblastoma had longer marsupialization periods than those with unicystic ameloblastoma ( P < .05). Conclusion Marsupialization is effective in reducing tumor size for both unicystic ameloblastoma and multicystic ameloblastoma. Marsupialization plus second‐stage curettage is recommended as the primary treatment for mandibular cystic ameloblastoma.
