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.
