摘要： 目的：探讨开窗减压术治疗颌骨大型牙源性角化囊性瘤的临床价值。方法：对22例牙源性角化囊性瘤进行开窗减压术，定期随访，待囊腔直径缩小至1~2 cm或连续观察3个月无明显变化时，行二期囊肿刮除术。结果：开窗减压期为3~24个月，影像学显示囊腔周围新骨再生，颌骨形态改建。二期刮除术后随访6~48个月，无复发病例。结论：开窗减压术是一种安全、有效微创治疗颌骨大型牙源性角化囊性瘤的方法。

Abstract: Objective: To investigate the clinical values of decompression for large keratocystic odontogenic tumor of jaws. Methods: 22 cases were treated with decompression, observed periodically. Subsequent curettage was given when the remaining tumors were less than 1~2cm in diameter or observed to be keeping no changes in 3 months. Results: The depression period lasted from 3 to 24 months, bone regeneration and reconstruction were noticed on radiographs. All patients were followed up for 6~48 months after secondary curettage, no recurrence was observed. Conclusion: Depression is a safe and effective minimally invasive treatment for large keratocystic odontogenic tumor of jaws.
