Endoscopic-assisted Surgical Removal of Infected Interosseous Wires 40 Years After Mandibular Surgery.
Case Report
We demonstrate a highly reliable minimally invasive treatment for removal of residual wire from the mandible. The patient was a 55-year-old Japanese man who was referred to our department for a fistula in his submental area. The patient had undergone open reduction and fixation with wires for mandibular fractures (left parasymphysis, right angle fracture) more than 40 years prior and mandibular tooth extraction and drainage 6 months prior. Minimally invasive endoscopy-assisted wire removal surgery was performed under general anesthesia with good visualization in a narrow surgical field. Bone resection was minimized using an ultrasonic cutting instrument with a wide choice of tip shapes. The use of endoscopy with ultrasonic cutting tools makes it possible to effectively utilize narrow surgical fields with a small skin incision and minimal bone cutting. The advantages and disadvantages of the newer endoscopic systems in oral and maxillofacial surgical units are discussed.
