New parameter for the evaluation of disgnathic patient's surgical planning: a preliminary report.

BACKGROUND

Indications for treatment of patients with maxillo-mandibular malformations have to be researched both in the severity of anatomical alteration affecting the face and psychological outcomes. Indeed, it has been underlined that patients decide to undergo orthodontic and orthognathic procedure mainly for aesthetical issues. Moreover the early combined functional and surgical treatment improves relationship skills in young adults. Dealing with these "aesthetic" features pre surgical planning presents some additional challenges. Even if orthognatic surgery aims to the correct repositioning of skeletal bases but we must achieve complete patient satisfaction.

AIM

The Authors present a new parameter to be considered in the planning of patients who undergo orthognatic procedure being the restitution of the face the patient would have had without any pathologic mechanism with respect of the aesthetic features of the family.

MATERIALS AND METHODS

Authors identified a series of parameters discussed by Arnett et al and performed a clinical and photographic evaluation of these parameters, in latero-lateral view, directly on the relatives of the patients. A cephalometric analysis, was performed and a series of parameters has been taken into account.

CONCLUSIONS

It is very difficult to standardize universal parameters acceptable and applicable for every single case, considering that patient's awareness of the anatomical defect and post-surgical satisfaction don't relate to the correct cephalometric evaluation and the real aesthetic outcomes.
