Summary
Oscillating saw breakage during intraoral vertical ramus osteotomy (IVRO) is a rare complication. This case report details successful retrieval of a broken saw blade, emphasizing preventative measures for patient safety.
Area of Science:
- Oral and Maxillofacial Surgery
- Surgical Complications
- Medical Device Safety
Background:
- Intraoral vertical ramus osteotomy (IVRO) is a surgical procedure.
- Oscillating saw breakage is a rare but serious complication during IVRO.
Observation:
- A 25-year-old female patient experienced oscillating saw breakage during IVRO.
- Initial retrieval attempts were unsuccessful; a broken blade was noted on CT scans.
- The broken blade was embedded in the right vertical ramus.
Findings:
- A secondary surgical procedure was performed six weeks post-initial surgery.
- The broken saw blade was successfully retrieved using a periosteal elevator and forceps.
- The retrieval was performed without complications.
Implications:
- Proper surgical technique is crucial to prevent overstraining the oscillating saw.
- Using new or well-maintained oscillating saws can minimize the risk of breakage.
- This case highlights a method for managing this rare surgical complication.
