【摘要】 目的 :研究超声联合CT导航行颅颌面颈部金属异物取出术的手术方法和临床疗效。方法 :回顾分析32例颅颌面颈部金属异物滞留患者的临床资料,通过超声联合CT导航实施异物取出。结果:32例患者的颅颌面颈部共滞留金属异物194颗,其中通过超声导航取出36颗,通过CT导航取出153颗,取出率达97.4%;术中定位准确,出血量少,术后患者均无明显手术并发症。结论:采用超声和CT导航,可精确定位并安全取出滞留于颅颌面颈部的金属异物,避免损伤重要的生理解剖结构,取得了良好的临床疗效。更多还原

【Abstract】 PURPOSE: To investigate the clinical efficiency of using ultrasonic navigation combined with CT to remove metal foreign bodies in the skull base and maxillofacial region. METHODS: The clinical data of 32 patients were reviewed. The metal foreign bodies were removed under ultrasonic navigation combined with CT. RESULTS: All 32 patients had good results and minor side effects. The foreign bodies were located accurately and removed with short operation time and less bleeding. Among 194 foreign bodies, 36 were removed under navigation ultrasound, 153 were removed under CT navigation; the total removal rate was 97.4%. CONCLUSIONS: Ultrasonic navigation and CT could fix accurately on the position of foreign body, avoiding important blood vessel and nerve injury during operation.更多还原
