The surgeon will evaluate the patient's specific needs and develop a customized surgical plan to address the underlying concerns. Re-surgery can involve various techniques, such as bone grafting, plate and screw fixation, or additional jaw repositioning.

The surgery is performed under general anesthesia, so there is no pain during surgery. Patients usually experience pain after the anesthesia wears off, which can last for a few days. This can be managed with painkillers. Orthognathic surgery is jaw surgery.

Results. Measured at B-point, skeletal relapse was 1.3 mm (30%) after mean advancement of 4.4 mm and 0.8 mm (12%) after setback of 6.0 mm. The magnitude of the surgical movement correlated with skeletal relapse. However, the correlation was not linear.

For more complicated surgery, the initial healing phase can last about six to eight weeks. Complete healing of the jaws can take between 9 and 12 months. As far as your appearance is concerned, any bruising that may occur will be gone after a few days.

MMA surgery is a type of corrective jaw surgery that is targeted at patients with sleep-related breathing disorders like obstructive sleep apnea (OSA). MMA can improve all airway levels, from the nasal cavity to the hypopharynx, and has around a 90% success rate as reported in the literature.

Swelling will result in the chin looking rounder and the lower lip puffier for approximately 2 weeks. After 2 months post-operatively, the tissue will appear much more normal to you. Final definition of the jaw line may require 4 months to attain.

The hierarchical pyramid of stability in orthognathic surgery was established, with two surgical procedures considered highly unstable: (1) maxillary expansion with semi-rigid internal fixation evaluated at the dental level in the posterior region, and (2) clockwise rotation of the mandible with rigid internal fixation ...

The current study revealed an overall infection rate of 12.4% within 1 year following orthognathic surgery. This is well within the infection rate of 10–15% expected by Peterson et al.
