This article presents the long-term results of treatment for a series of unicystic ameloblastoma of the mandible.
Twenty-one patients were seen within a 15-year period. The median age at onset of symptoms was 18 years, with a median delay before presentation of 4 years. The male/female ratio was 1.3:1. Treatment was enucleation with primary closure in 11 patients (52.4%) whose lesions were in the horizontal body of the mandible. Five patients (23.8%) had excision of the lesion and the encompassing dentoalveolar process with preservation of the lower border of the mandible. Because the disease involved the ascending ramus of the mandible in five patients (23.8%), full-thickness resection of the affected mandible was done.
There were three recurrences: Two in patients managed with enucleation and one in a patient who had resection of the lesion with preservation of the lower border of the mandible.
The findings show that unicystic ameloblastoma often can be treated successfully with less aggressive surgery than that needed for multicystic ameloblastoma.
本文介绍了一系列下颌骨单囊性成釉细胞瘤的长期治疗结果。
在15年期间共诊治21例患者。症状出现时的中位年龄为18岁，就诊前的中位延迟时间为4年。男女比例为1.3:1。11例（52.4%）病变位于下颌骨水平体部的患者采用摘除术并一期缝合治疗。5例（23.8%）患者切除病变及周围牙槽突，保留下颌骨下缘。5例（23.8%）患者因病变累及下颌骨升支，行患侧下颌骨全层切除术。
有3例复发：2例采用摘除术治疗的患者复发，1例切除病变并保留下颌骨下缘的患者复发。
研究结果表明，与多囊性成釉细胞瘤相比，单囊性成釉细胞瘤通常采用侵袭性较小的手术就能成功治疗。
