Abstract
OBJECTIVE Orthognathic surgery is a complex orofacial surgery that can significantly impact occlusal function and effect nutritional and quality of life parameters. This study aimed to evaluate alterations in dietary intake, chewing function, physical activity, and oral health-related quality of life of patients undergoing orthognathic surgery. RESEARCH METHODS AND PROCEDURES In this prospective longitudinal study, the assessments were conducted at: preoperatively (T0) and postoperative first week (T1), second week (T2), first month (T3), and third month (T4) between May 2021 and March 2023. Sociodemographic questionnaire, 24-h dietary recall record, chewing ability form, International Physical Activity Questionnaire, and Oral Health Impact Profile-14 (OHIP-14) was applied at face-to-face interviews. RESULTS Seventy eligible orthognathic surgery patients were evaluated, and 37 patients (52.8%) completed this study. Energy and fat intake significantly decreased from T0 to T1 (P < 0.001) and returned to basis by T4 (P = 0.015). Fiber intake was found to be lowest at T1 and T2 compared with other time points (P < 0.001). Chewing ability showed a deterioration and then improvement; however, patients still had difficulties chewing hard foods at T4. The OHIP-14 increased at T2 and T3 from T0 (P < 0.001 and P = 0.021, respectively) and showed a significant improvement at T4 (P < 0.05). CONCLUSION The findings indicate a temporary decline in nutritional intake and chewing ability with subsequent recovery by the third month postsurgery. These changes, along with the trends in oral health-related quality of life, underscore the need for tailored nutritional and functional rehabilitation programs following orthognathic surgery.

Abstract
The aim of this study was to investigate the impact of bimaxillary orthognathic surgery on patients' anthropometric measures and laboratory parameters. This study was conducted on patients who underwent bimaxillary orthognathic surgery. Anthropometric measurements were collected before surgery (T0) and at intervals of one week (T1), two weeks (T2), one month (T3), and three months (T4) postoperatively, and laboratory parameters at T0 and T4. Data analysis included repeated-measures ANOVA for assessing weight changes, body mass index (BMI) and fat percentage changes, the Friedman test for muscle mass changes, and independent t tests to understand gender-based differences. Significant reductions were observed in weight (mean differences ranging from 2.26 kg to 3.84 kg, 95.00% CI: 1.29 to 4.62, p < 0.01) and BMI (mean differences ranging from 0.76 to 1.32, 95.00% CI: 0.38 to 1.58, p < 0.01) postoperatively at all follow-up points. Fat percentage changes were significant between T0 - T3 (MD = 1.17, 95.00% CI: 0.26 to 2.08, p < 0.05) and T0 - T4 (MD = 1.28, 95.00% CI: 0.14 to 2.43, p < 0.05). Changes in muscle mass were significant until T3 (MD ranging from 71.00 to 107.0, p < 0.01). Also, haemoglobin levels were significantly higher at T0 than T4 (MD = 0.35, 95% CI: 0 to 0.7). These changes showed no significant gender-based differences (p > 0.05). Our study showed that orthognathic surgery prompts temporary changes in body weight, Body Mass Index, and haemoglobin levels. Future research should explore interventions to mitigate these changes and enhance postoperative recovery.

Abstract
INTRODUCTION Orthognathic surgery is routinely practiced, yet little comparative data exists to evaluate post-orthognathic surgery diet protocols. OBJECTIVE To evaluate which postoperative diet protocols are recommended and to quantify post-orthognathic surgery weight changes in our institutional cohort. METHODS An internet search was carried out on Google for "orthognathic surgery diet" and the postoperative diet recommendations from centers worldwide were quantified. Additionally, a retrospective analysis of patients that underwent orthognathic surgery at our institution was performed, and their preoperative and postoperative weights were recorded. RESULTS The internet search yielded 58 centers that met our inclusion criteria. Most centers were in the United States (n = 37, 63.8%) and were oral and maxillofacial surgeon (OMFS)-led centers (n = 39, 67.2%). Postoperative diets were categorized into 7 distinct protocols, ranging from most to least restrictive-the most popular was liquid diet for 2 to 4 weeks followed by soft diet for 2 to 6 weeks. There were no significant patterns observed across different geographical regions or specialties.In our institution, 135 patients were identified. Overall, there was an average maximum weight loss of 4.1 kg by week 4, followed by a gradual increase in weight. Linear regression analysis showed that patients with greater preoperative body mass index (BMI) lost more weight postoperatively than patients with lower BMI (R2 = 0.25, P < .001). CONCLUSION There is a significant variability in recommended postoperative diets following orthognathic surgery. Following a moderately restrictive diet at our institution, patients returned to their preoperative weight after approximately 4 months.

Abstract
INTRODUCTION The aim of this study was to compare body weight loss between postoperative intermaxillary fixation with metal wire and elastic traction and to investigate factors related to body weight loss after orthognathic surgery. MATERIALS AND METHODS Subjects were 59 patients with dentofacial deformity, comprising 31 patients treated with intermaxillary fixation (IMF) and 28 patients treated with elastic traction without IMF (ELT) just after surgery. Body weight loss was measured at 1 week (T1) and 2 weeks (T2) after surgery. Body weight loss was compared between IMF and ELT, and factors related to body weight loss were statistically analyzed. RESULTS Body weight loss ratio was significantly increased in IMF (2.6%) rather than in ELT (1.4%) at T1, but only tended to be increased in both groups at T2, showing no statistical difference. Body weight loss ratio was significantly increased at T2 compared to T1 in both groups. Body weight loss was significantly greater at T2 than at T1. CONCLUSION Both IMF and ELT cause body weight loss after orthognathic surgery, but IMF causes body weight loss earlier than ELT and increased early body weight loss increases continuous body weight loss after orthognathic surgery.

Abstract
PURPOSE The purpose of this study was to evaluate patients' nutritional state after orthognathic surgery. METHODS The subjects were 40 female patients with dentofacial deformity aged 17-33 years who were undergoing bilateral sagittal splitting ramus osteotomy. Twenty patients were treated with intermaxillary fixation, and 20 patients were treated without intermaxillary fixation. Age and body mass index (kg/m2) were assessed as physical factors, operation time, blood loss, and amount of mandibular movement with or without intermaxillary fixation were assessed as operation stress factors, and the following laboratory data, total protein, serum albumin, total cholesterol, total lymphocytes, and cholinesterase were assessed as nutritional state factors at 1 and 2 weeks after surgery. Statistical analysis was performed for body weight loss and relationship between body weight loss and examination factors. RESULTS Body weight significantly decreased 2.3% at 1 week and 3.9% at 2 weeks after surgery rather than preoperation. All laboratory data except total lymphocyte were decreased at 1 week after surgery and still remained significantly decreased at 2 weeks after surgery. There was a statistically significant relationship between body weight loss at 1 week after surgery and operation time. CONCLUSIONS These results indicate that long operation time caused body weight loss in orthognathic surgery.

Abstract
BACKGROUND To investigate retrospectively the orthognathic surgery (OGS) patients experience in weight loss and the influence of gender, age, duration of the surgical procedure, length of hospital stay, location of surgery and use of intermaxillary fixation (IMF) or without IMF on postoperative weight loss. MATERIAL AND METHODS A total of 4487 patients treated by OGS where all patients visited the outpatient clinic one, three and six weeks after the surgical procedure. After six weeks, patients filled out a questionnaire in which weight loss was addressed. The patients were asked to give an estimate of their experiences weight loss. The population was first divided in two groups weight loss and no weight loss. RESULTS In the weight loss group there is no significant difference in weight loss between patients with IMF and patients without IMF. In the weight loss group there were significantly more females then males. Further, in the subgroup IMF the operation time was significantly longer compared with the subgroup without IMF. The other parameters including age and hospital stay were not different in the groups. CONCLUSIONS IMF in orthognathic treatment does not result in a difference self-reported loss of body weight compared to patients without IMF. Treatment protocols should include pre- and post-operative dietician consultations and possible indications for medical nutrition and vitamins. Key words:Assessing, protocol, weight loss, experiences, orthognathic surgery.

Abstract
Background. One of the treatment modalities for facial fractures is closed reduction technique, but treatment with intermaxillary fixation (IMF) interferes with normal nutrition, and malnutrition can affect the patient’s recovery. Anthropometric measurements such as skinfold thickness and body mass index (BMI) are universal indexes for diagnosing malnutrition. Therefore, in this study we explain how treatment with IMF changes the anthropometric indexes. Methods. In this study 60 patients were treated with 4 weeks of IMF. Skinfold thickness and BMI of these patients were measured and compared before and after the treatment. Results. Patients’ weight, BMI and skinfold thickness decreased during the IMF period, and this decrease was statistically significant (P < 0.01). Conclusion. Although no severe and acute malnutrition was seen among our patients, IMF led to mild to moderate malnutrition in some cases, making it necessary to use nutritional supplements.

Abstract
BACKGROUND In Oral and Maxillofacial Surgery, the majority of the condylar fractures are treated by closed reduction with generally satisfactory long term results. But in such cases of closed reduction, patient will be uncomfortable owing to long term application of inter maxillary fixation (IMF). Where as, Disadvantages of extra oral open reduction and fixation of condylar fracture includes facial nerve damage, facial scars etc. which are surely eliminated by the intraoral reduction and rigid fixation. AIMS AND OBJECTIVES The present study was conducted to determine the efficacy of reduction and fixation of low sub-condylar fractures through intra-oral approach. METHODOLOGY In this study, ten patients with low sub-condylar fracture, reported to department of Oral and Maxillofacial Surgery. P.M.N.M. Dental College and Hospital Bagalkot were included. These patients were treated by open reduction and internal fixation through intra-oral approach. All the patients were evaluated postoperatively for mouth opening, occlusion and mandibular deviation with regular radiographic examination for 6 weeks. RESULTS All operated patients followed for 6 weeks, maximum mouth opening was more than 40 mm in seven patients (range from 40 to 50 mm) and less than 40 mm in three patients. Occlusion was satisfactory in all and none of the patients showed deviation of mandible on mouth opening. Statistical analysis showed that postoperative mouth opening was significant ('t' value = 7.88, 'P' = (0.000) < 0.05) and the test result was significant (S) at 5% level of significance. Statistical analysis of deviation of mouth opening was nonsignificant ['t' value = 1.96, 'P' value (0.081), 0.05]. For occlusion standard photographs were obtained at sixth week and found minor occlusal corrections in two patients are treated by elastic traction for few days. DISCUSSION AND CONCLUSION Open reduction with internal fixation through intraoral approach has proved to be safe for early function and also effective by avoiding the patient discomfort due to long term intermaxillary fixation, psychological effect, facial nerve damage, facial scar and weight loss.

Abstract
Mandibulo-maxillary fixation (MMF) screws are inserted into the bony base of both jaws in the process of fracture realignment and immobilisation. The screw heads act as anchor points to fasten wire loops or rubber bands connecting the mandible to the maxilla. Traditional interdental chain-linked wiring or arch bar techniques provide the anchorage by attached cleats, hooks, or eyelets. In comparison to these tooth-borne appliances MMF screws facilitate and shorten the way to achieve intermaxillary fixation considerably. In addition, MMF screws help to reduce the hazards of glove perforation and wire stick injuries. On the downside, MMF screws are attributed with the risk of tooth root damage and a lack of versatility beyond the pure maintenance of occlusion such as stabilizing loose teeth or splinting fragments of the alveolar process. The surgical technique of MMF screws as well as the pros and cons of the clinical application are reviewed. The adequate screw placement to prevent serious tooth root injuries is still an issue to rethink and modify conceptual guidelines.
