Impact of orthognathic surgery on quality of life in patients with different dentofacial deformities1498Planning and surgeryEach patient underwent preoperative orthodontic alignment with fixed orthodontic braces for approximately 18 months. They also received postoperative orthodontic alignment with fixed orthodontic braces for another 6 months. Analysis and treatment planning were carried out with study models mounted on an adjustable articulator to facilitate three-dimensional planning and manufacturing of the interocclusal positioning wafers. Patients in the study received one of the following surgical corrections: Le Fort 1 osteotomy, bilateral sagittal split osteotomy (BSSO), bimaxillary osteotomy (BIMAX), or osteotomy combined with genioplasty. Postsurgical stabilization was achieved with elastics during the first 2 weeks of healing. The patients were followed up for at least 1 year after surgery. Data collection Demographic information (gender, date of birth) and information about the surgery (date of surgery, type of surgery, indication for surgery, blood loss, and time of surgery) were collected from the medical records for each patient included in the study. The patients were asked to complete a questionnaire before the operation (T0, baseline) and every day for the first 7 days after the surgery (T1-T7). The next questionnaires were completed postoperatively at 4 weeks (T8), 6 months (T9), and at least 1 year (T10). During the first 6 months of the study, the patients received a written questionnaire; thereafter, online questionnaires were sent by email. As a result, some patients received all of the questionnaires online, whereas others received only the last one online. Lime Survey 2.6.4. was used as a tool for online surveys and quota management (LimeSurvey GmbH. LimeSurvey (2.6.4.).Patients received two reminders if they did not respond after 1 week. The questionnaire used for this study was OHIP-14NL.19 This questionnaire focuses on the impact of a person’s oral health on QoL, evaluating the following domains: functional limitation, physical pain, psychological discomfort, physical disability, psychological disability, social disability, and handicap. Answers to each question indicated the frequency of occurrence, with five possible answers: 0 = never, 1 = hardly ever, 2 = occasionally, 3 = fairly often, 4 = very often. The total OHIP score was the sum of the answers to the 14 questions. Scores ranged from 0-56, with higher scores indicating
