自制囊肿引流管治疗巨大下颌骨囊性病变的临床疗效及应用体会

Treatment of giant mandibular cystic lesions with homemade cyst drainage tube:Clinical efficacy and application experience

目的:评价使用自制囊肿引流管在治疗下颌骨巨大囊性病变开窗减压术中的疗效。方法:选取12例下颌骨巨大囊性病变患者经自制囊肿引流管开窗减压术治疗,减压术后引流期维持6-20个月,测量减压术后病灶直径,评价临床疗效。所有患者均行二期囊肿刮治手术。术后随访12-60个月。结果:影像学结果显示,开窗减压术后3个月,囊肿周围骨质出现再生改建,后期囊腔明显缩小,下牙槽神经管外形恢复。自制引流管开窗减压术治疗颌骨巨大囊性病变的有效率为100%,二期手术后,本组资料随访期间未发现复发。结论:自制囊肿引流管制作简便,开窗减压术是治疗下颌骨巨大囊性病变安全、有效的方法。

Objective:The purpose of this report was to evaluate the clinical efficacy of homemade cyst drainage tube in fenestration and decompression for giant mandibular cystic lesions.Methods:A total of 12 patients with giant mandibular cystic lesion underwent fenestration decompression received the therapy of homemade cyst drainage tube for 6-20 months.Diameters of cyst cavity and clinical efficacy were recorded and assessed.All 12 patients underwent secondary curettage of postoperative cyst wall and were followed up varied from 12 months to 60 months.Results:Radiological examination showed that the bone around the cyst was regenerated and reconstructed at 3 months after decompression surgery,and the volume of cystic cavity was reduced significantly,and the shape of the inferior alveolar canal was restored.The efficiency of fenestration decompression in the treatment of giant mandibular cystic lesions was 100%,and no recurrence was found during the follow-up period in the second stage.Conclusion:The author believes that long-term maintenance of homemade cyst drainage tube after fenestration decompression is a safe and effective method for the treatment of giant cystic lesions of the mandible.
