Skeletal stability in orthognathic surgery with the surgery first approach: a systematic review.

Summary of "Skeletal stability in orthognathic surgery with the surgery first approach: a systematic review."

The surgery first approach (SFA) is a therapeutic strategy used in orthognathic surgery that is constantly evolving. With this approach, the pre-surgical orthodontic treatment can be eliminated, the maxilla and the mandible are surgically repositioned into the desired position, and the therapy is ended with a short orthodontic phase. Several studies have reported that the SFA is an acceptable approach, but postoperative stability is unclear. In this study, a systematic review on the SFA was performed. The PubMed, Google Scholar, Scopus, LexisNexis, Web of Science, and Cochrane Library databases were accessed. Studies from which data could be extracted on skeletal stability based on specific cephalometric points were included. The search yielded 2766 publications. Application of the selection criteria resulted in a final group of 14 articles. Five hundred and sixty patients with class III malocclusion underwent orthognathic surgery, 339 with the SFA. Study parameters such as evaluation time points and reference planes varied, making it impossible to perform a meta-analysis. The studies suggest that surgery with the SFA is as stable as surgery with the conventional approach. However, all articles described stability using a penultimate time point of 'after surgery' and not 'after debonding'; hence orthodontic movements and consequent mandibular movements could have influenced cephalometric measurements. Thus, to verify the real stability of the SFA, further research with longer follow-up periods is required, with evaluation at the same time points.

Medical and Biotech [MESH] Definitions

Surgery performed to repair or correct the skeletal anomalies of the jaw and its associated dental and facial structures (e.g. CLEFT PALATE).

A surgical specialty concerned with correcting conditions related to malposition of the jawbones and other related MAXILLOFACIAL ABNORMALITIES (e.g., CLEFT PALATE; RETROGNATHISM).

Surgical procedures conducted with the aid of computers. This is most frequently used in orthopedic and laparoscopic surgery for implant placement and instrument guidance. Image-guided surgery interactively combines prior CT scans or MRI images with real-time video.

Surgery which could be postponed or not done at all without danger to the patient. Elective surgery includes procedures to correct non-life-threatening medical problems as well as to alleviate conditions causing psychological stress or other potential risk to patients, e.g., cosmetic or contraceptive surgery.
