Summary
Orthognathic surgery, including mandibular and maxillary osteotomies, corrects facial defects. Radiographs help identify normal healing and potential complications after these common procedures.
Area of Science:
- Oral and Maxillofacial Surgery
- Radiology
- Orthodontics
Background:
- Orthognathic surgery corrects significant facial skeletal discrepancies.
- Radiographic imaging is crucial for pre- and post-operative assessment.
- Understanding normal postoperative findings is essential for accurate interpretation.
Purpose of the Study:
- To describe common osteotomies of the mandible and maxilla.
- To illustrate the typical radiographic appearance of uncomplicated orthognathic surgery.
- To aid radiologists in identifying surgical complications.
Main Methods:
- Review of common orthognathic surgical techniques (e.g., sagittal split, Le Fort I).
- Analysis of posteroanterior skull and panoramic radiographs.
- Description of metallic fixation devices and orthodontic appliances.
Main Results:
- Detailed description of standard osteotomies: sagittal split, vertical subcondylar, genioplasty, Le Fort I, and mid-palatal split.
- Presentation of characteristic radiographic findings for uncomplicated procedures.
- Identification of common hardware and appliances used for stabilization.
Conclusions:
- Familiarity with orthognathic surgical procedures and their radiographic outcomes is vital for radiologists.
- Radiographs are key to monitoring patient recovery and detecting potential surgical complications.
- This review provides a guide to interpreting postoperative imaging in orthognathic surgery.
