Summary
Intraoperative cone beam computed tomography (CBCT) provides reliable 3D imaging for mandibular reconstruction. This technique offers crucial visual control during complex surgeries, improving outcomes.
Area of Science:
- Oral and Maxillofacial Surgery
- Medical Imaging
- 3D Reconstruction
Background:
- Mandibular reconstruction involves complex surgical procedures.
- Intraoperative visualization can be challenging for certain anatomical structures.
Purpose of the Study:
- To investigate the utility of 3D imaging using intraoperative cone beam computed tomography (CBCT) in major mandibular reconstruction.
- To assess the effectiveness of CBCT for intraoperative guidance.
Main Methods:
- A study group of 125 patients undergoing various mandibular procedures (fracture repair, orthognathic, reconstructive surgery) was included.
- Intraoperative 3D images were acquired using a mobile CBCT scanner.
- The study encompassed a wide age range, from 3 months to 91 years.
Main Results:
- CBCT effectively visualized difficult-to-access areas, such as the lingual cortical bone of the mandible.
- The technique allowed for evaluation of screw placement, particularly near the alveolar nerve.
- Image quality was sufficient for postoperative assessment in all cases.
Conclusions:
- Intraoperative CBCT is a reliable imaging modality for major mandibular procedures.
- It provides essential visual control during surgery, enhancing procedural accuracy.
