口腔颌面部穿孔伤伴有异物的存留,是较严重的颌面外伤之一。特别是金属异物,更较其它异物为多,在几年来的临床实践中,我们采用了十字金属丝坐标定位,校正一般X线定位误差,并结合应用眼科电磁吸铁器,使手术成功率明显提高。现将口腔颌面部磁性异物的定位与手术的粗浅体会报告如下。一、临床资料 (一)性别:在14例颌面部磁性异物中,男 Oral and maxillofacial perforation injury with foreign body retention, is one of the more serious maxillofacial trauma. Especially metal foreign bodies, but more than other foreign bodies, in the past few years of clinical practice, we use the cross metal wire positioning coordinates to correct the general X-ray positioning error, combined with the use of ophthalmic electromagnetic iron attractors, so that the success rate of surgery increased significantly . Now oral and maxillofacial magnetic foreign body positioning and surgical report of the superficial experience is as follows. First, the clinical data (a) gender: in 14 cases of maxillofacial magnetic foreign body, male
