Aesthetics and function of maxillofacial district are closely related and could interfere with patient psychological conditions. The aim of this paper is to describe and to analyze the procedures necessary for a proper surgical visualized treatment objective (VTO) realization through the use of the tracing on lateral head film, applying the divine proportion (or golden ratio) in certain steps. The method described is easy to realize, cheap and help both orthodontist and maxillo-facial surgeon to communicate each other and to the patients. For the following article, digital research and handheld research on surgical VTO planning for patients with skeletal or dentoalveolar severe deformities managed by surgeons and orthodontics were used. The research included articles in English published on dental and maxillofacial surgery journals. The surgical VTO consists of a "previsualization" of the objectives in order to make the desired changes for the individual patient. The result can thus be visualized and pre-evaluated rather than just imagined by the mind's eye. To simplify the procedure, the surgical VTO has been divided into 11 steps. The accurate model of the surgical result is fundamental in the treatment of dentofacial deformities. These predictions are intended to guide the treatment towards the desired result, to give the patient a reasonable preview of the outcome, and to ensure communication between the orthodontist and the surgeon. This technique proves to be effective in planning surgical treatment and it allows the clinician to view changes before, during, and after orthognathic surgery. The skeletal, dental, and aesthetic complete cephalometric evaluation is the key point to the long-term success of the results.
