This study evaluated the results of the use of curettage followed by liquid nitrogen spray cryosurgery in a number of solid or multicystic ameloblastomas of the jaws and the postoperative complications related to this treatment modality.
Thirty-six patients with solid ameloblastoma of the jaws were treated with curettage followed by cryosurgery. The cryotherapy consisted of hand instrumented curettage of the bone lesion followed by three freezing cycles, of 1 minute each, of the remaining bone cavity with liquid nitrogen spray. Postoperative complications were evaluated clinically and radiographically.
Local recurrence occurred in 11 (30.6%) patients. Excepting local recurrence, postoperative complications were frequent but not severe: wound dehiscence (5.5%), paraesthesia (5.5%), infection (5.5%), and pathologic fracture (11.1%).
Management of solid or multicystic ameloblastomas of the jaws with curettage followed by cryosurgery may decrease the local recurrence rate and also to reduce the initial indication of resection with continuity defect.
本研究评估了刮除术联合液氮喷雾冷冻手术治疗颌骨实性或多囊性成釉细胞瘤的效果以及与该治疗方式相关的术后并发症。
36例颌骨实性成釉细胞瘤患者接受了刮除术联合冷冻手术治疗。冷冻治疗包括用手动器械刮除骨病变，然后用液氮喷雾对剩余骨腔进行三个周期的冷冻，每个周期1分钟。通过临床和影像学评估术后并发症。
11例（30.6%）患者出现局部复发。除局部复发外，术后并发症常见但不严重：伤口裂开（5.5%）、感觉异常（5.5%）、感染（5.5%）和病理性骨折（11.1%）。
采用刮除术联合冷冻手术治疗颌骨实性或多囊性成釉细胞瘤可能会降低局部复发率，并减少连续性缺损切除的初始指征。
