Summary
Computer-aided planning in orthognathic surgery demonstrates accuracy in planning complex procedures. However, further high-quality research is required to confirm its benefits over conventional methods.
Area of Science:
- Oral and Maxillofacial Surgery
- Medical Imaging and Computer-Assisted Surgery
Background:
- Orthognathic surgery corrects jaw and facial irregularities.
- Computer-aided planning (CAP) offers potential improvements in surgical precision.
Approach:
- Systematic review of nine studies evaluating CAP accuracy in orthognathic surgery.
- Searches conducted across major biomedical databases (PubMed, EMBASE, Cochrane Library, LILACS, SciELO).
- Independent, blinded assessment of study selection and eligibility criteria.
Key Points:
- CAP demonstrated accuracy with translation errors <1.2mm and rotational errors <1.8°.
- High or medium risk of bias was identified in all included studies.
- Substantial agreement (κ=0.767) and excellent agreement (κ=0.863) were noted in study selection and eligibility.
Conclusions:
- Computer-aided planning is accurate for orthognathic surgery based on current evidence.
- Low study quality necessitates randomized clinical trials to compare CAP with conventional planning.
