What do you think about this as a presurgical treatment?

Conservative treatment of Angle Class III malocclusion with anterior crossbite

That patient was almost 16yo so he was after maxillary growth "time". Yet he still got quite good results.

Entire Splanchnocranium was moved forward and downward, especially midface was very well brought forward. Treatment took over year but actually I think results were worth it.


TREATMENT PLAN

Although occlusal findings suggested the need for a more invasive treatment approach because of negative overjet in the anterior region, patient's age and facial esthetics pointed towards conservative treatment. Therefore, treatment was planned to correct Class III skeletal pattern by taking advantage of his remaining growth potential and by performing tooth movement to achieve buccal inclination of maxillary incisors.3

A decision was then made to choose mechanisms that would facilitate, during alignment and leveling phases, the achievement of normal occlusion between molars and between canines, correct lateral and protrusive guidance and achieve inclination of maxillary incisors, so as to obtain greater projection of the upper lip and preserve passive lip seal. To this end, the use of fixed orthodontic appliance was chosen for both maxillary and mandibular arches. The retention phase, to be initiated after the completion of active treatment, comprised the use of a modified removable Hawley retainer for the maxillary arch, indicated to be used for 14 to 18 hours a day for one year, followed by overnight use for two more years. A fixed intercanine bar made of 0.016-in untampered stainless steel was placed in the mandibular arch. In that phase, special attention should be given to the development of third molars.

This and midfacial augmentation (here is some good result)

Would provide much better results than any modification of Lefort 3.
@RealSurgerymax what do you think about the study?

Dont expect the same results

This guy seems to be a late bloomer growth wise which is why the growth increments are so large especially on the maxilla in such a short time. A normal person his age would have gotten more mandibular change compared to the maxilla in that small period of time.
