内镜及计算机导航辅助下颌面部异物取出5例临床分析
Clinical analysis of five cases of endoscopic and computer navigation-assisted maxillofacial foreign body re-moval
摘要
Abstract
Objective To explore the application method and clinical efficacy of endoscopic and computerized navigation technology in maxillofacial foreign body removal surgery,and to provide a reference for the clinical applica-tion of this technology.Methods This study,which was approved by the Medical Ethics Committee of the hospital,retrospectively analyzed the data of five patients with maxillofacial foreign bodies who were admitted to Sun Yat-sen Me-morial Hospital,Sun Yat-sen University from January 2018 to December 2024.All patients underwent preoperative CT scanning.Intraoperatively,endoscopic and computer navigation techniques were used in combination or separately ac-cording to the location,size,and adjacency of the foreign body to important neurovascular vessels.The foreign body was precisely localized by endoscopic magnification and direct visualization,and the optimal surgical path was designed and verified under the real-time guidance of computerized navigation to accurately remove the foreign body.The type of for-eign body,location,length and diameter,duration of surgery,length of incision,success rate of foreign body removal,postoperative complications,and follow-up were recorded and analyzed.Results The foreign body was successfully re-moved in all five patients with a success rate of 100％.The intraoperative computerized navigation system was accurate in positioning,and the alignment stability was not significantly affected by mandibular movement;the endoscope pro-vided good illumination and exposure of the operative field.All surgical incisions were small,and no serious complica-tions,such as foreign body residue,important neurovascular injury,or infection,occurred after surgery.One month after the operation,the patients were followed up and recovered well.Conclusion The combination of endoscopy and com-puter navigation or separately assisted technology can provide a clear field and real-time positioning for maxillofacial foreign body removal,effectively avoiding important anatomical structures,thus realizing safe and complete foreign body removal with minimized trauma.This assistive technology significantly improves the accuracy and safety of the opera-tion and has clinical promotion value.关键词
