开窗减压术治疗上颌骨大型囊性病变的临床研究

目的：探讨开窗减压术在上颌骨大型囊性病变治疗中的临床应用效果。方法回顾2007年10月—2014年10月治疗的25例上颌骨大型囊性病变开窗减压术治疗病例，观察上颌窦形态、囊腔大小及周围骨质变化。结果25例患者中，8例患者开窗减压术后3个月上颌窦骨壁厚度增加，上颌窦形态完全恢复，囊肿消失，未行囊肿刮治术；17例患者术后9～12个月上颌窦形态完全恢复或基本恢复，二期行囊肿刮治术。术后随访1～5年，无复发。结论上颌骨大型囊性病变开窗减压术具有能恢复上颌窦的形态和功能、创伤小、并发症少等优点。

Clinical study of large maxillary cystic lesions treated by decompression

Objective To evaluate the effects of decompression in treating large maxillary cystic lesions. Meth?ods 25 cases of large maxillary cystic lesions were performed decompression during Oct. 2007?Oct. 2014. According to the clinical and radiological examination, morphology of maxillary sinus and cyst cavity were observed. Results 12 cases of radicular cysts, 10 cases of dentigerous cysts, and 3 cases of keratocystic odontogenic tumor were diagnosed ac?cording to pathological examination. The appearance of the maxillary sinus were completely restored and the cyst disap?peared totally in 7 cases after the first 3 months, and then after the next 9?12 months, the other 18 cases had the appear?ance of maxillary sinus completely or basically restored with a following enucleation of cysts. All patients were followed up for 1?5 years, and no recurrence was observed. Conclusion To treat large maxillary cystic lesions by decompres?sion is effective to conserve the morphology and function of maxillary sinus, and it is a simple surgical approach with less damage and complications.
