目的探讨摘取眼眶细小金属异物的有效方法及手术技巧。方法对17例眼眶金属异物行C臂机电视定位,引导注射针头进入并与异物接触,注入适量气体使金属异物与周围软组织分离,于眼睑部或结膜部作切口,用蚊式血管钳进入,夹持金属异物并缓慢取出。结果17例眼眶细小金属异物均顺利取出,术后未对视力造成不良影响。结论X线电视监视下异物旁注气协助眼眶细小金属异物取出是一种简便、实用、有效且创伤小的眼眶细小金属异物取出的方法。
Objective To investigate the effective methods and techniques of extracting orbital small metallic foreign bodies. Methods Seventeen cases of orbital metal foreign bodies were located by C-arm and TV. The injection needle was guided into contact with foreign bodies, and an appropriate amount of gas was injected to separate the metal foreign bodies from the surrounding soft tissues. The eyelid or conjunctiva was incised and injected with mosquito- Hold metal foreign objects and remove slowly. Results 17 cases of orbital small metallic foreign bodies were successfully removed, postoperative visual acuity was not adversely affected. Conclusion X-ray TV monitoring foreign body next to the gas injection to assist the removal of small orbital metal foreign body is a simple, practical, effective and traumatic small orbital removal of small metallic foreign bodies.
