Interventions

Fifty adult patients, from a consecutive convenience sample, were analyzed according to the facial pattern of the dentofacial deformity profile, separated into 2 groups: facial pattern II with 24 pati
T1: 3 months postoperative
and T2: 6 months postoperative), the patients answered the Orthognathic Quality of Life Questionnaire (OQLQ) and the Quality of Life Questionnaire Related to the Oral Health Impact Profile (OHIP-14),

Eligibility

Age
18 Years to 60 Years

Inclusion criteria

Inclusion criteria: Adult patients between 18 and 60 years of age; literate and without cognitive impairment; presenting a diagnosis of dentofacial deformities for which orthodontic treatment to align, level, and remove dental compensations has been performed prior to orthognathic surgery

Exclusion criteria

Exclusion criteria: Patients who had previously undergone orthognathic surgery; history of treatment for facial fractures; congenital craniofacial syndromes; patients who underwent genioplasty in conjunction with orthognathic surgery; patients classified with a type I facial profile pattern; patients who did not respond to the questionnaires at all stipulated evaluation times

Design outcomes

Primary

MeasureTime frame
To assess quality of life after correction of type II and III facial profile patterns through orthognathic surgery, preoperatively and up to 6 months postoperatively. Two questionnaires were used: the Brazilian adaptation of the Orthognathic Quality of Life Questionnaire (OQLQ), consisting of 22 questions and a total score ranging from 0 to 88 points, and the Brazilian version of the Oral Health Impact Profile (OHIP-14) quality of life questionnaire, consisting of 14 questions and a total score ranging from 0 to 56 points. In both questionnaires, the lower the score, the better the patient's quality of life. The evaluator who will calculate the scores for the questionnaires will remain blind to the study groups and time points.

Secondary

MeasureTime frame
To assess whether the quality of life of patients was influenced by the location of orthognathic surgery, performed through unimaxillary surgeries (only the mandible operated in facial pattern II or only the maxilla operated in facial pattern III) and bimaxillary surgeries (mandible and maxilla operated in both facial patterns).
