Evaluation of pre- and postoperative nutrition and oral health-related quality of life in orthognathic surgery patients.

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.

Chewing difficulties, oral health, and nutritional status in adults with intellectual disabilities: A cross-sectional study.

BACKGROUND: Chewing difficulty, poor oral health, inadequate and imbalanced nutrition are serious health problems in individuals with intellectual disabilities. The participants' chewing abilities, oral health and nutritional status were analysed in this study. METHODS: Forty-five adult participants with intellectual disabilities were included. Anthropometric measurements, oral health assessments, chewing ability evaluations and dietary intake analyses were conducted. RESULTS: A 56.8% of the participants were classified as overweight or obese. Teeth grinding was reported in 33.3% of the participants, while 40.0% experienced drooling. All participants with Down syndrome and 58.6% of the participants with developmental delay had chewing difficulties. Inadequate nutrient intake was observed and the fibre, vitamins B1, B3, B9, sodium, phosphorus and iron intakes were significantly lower than reference values in those with chewing difficulty (p < .05). CONCLUSIONS: Chewing difficulties were associated with lower intake of certain nutrients, highlighting the importance of addressing oral health and dietary counselling in this population.

The Predictive Value of Cold Pack Test for Pain After Third Molar Surgery.

BACKGROUND: Early identification of patients who are prone to postoperative pain may provide individualization of postoperative analgesia strategies. PURPOSE: The aim of the study was to investigate whether the cold pack test is associated with postoperative pain levels after mandibular third molar surgery. STUDY DESIGN, SETTING, SAMPLE: This prospective cohort study included healthy male patients admitted to Department of Oral and Maxillofacial Surgery of a tertiary health-care center between June 2022 and December 2022 and scheduled for lower third molar extraction. Those who had used any analgesic within the past 10 days or had a history of intolerance/allergy to analgesics were excluded. PREDICTOR VARIABLE: The primary predictor variable was pain tolerance, measured using the endurance test score. Subjects were grouped into two categories, low tolerance test score (withdrew the hand from the cold pack in <240 seconds) and high tolerance test score (maintained the hand on the cold pack for 240 seconds). MAIN OUTCOME VARIABLES: The primary outcome variable was pain measured by the patients from 0 to 10 with the visual analog scale, and the secondary outcome variables were the amount of ibuprofen and paracetamol consumed in the postoperative period. Pain measurements and ibuprofen consumption were recorded at 0-2, 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, and 96 hours (0-2 interval of the first 2 hours immediately after surgery). COVARIATES: Age, classification and position of mandibular third molar were utilized as covariates. ANALYSES: The relationship between pain tolerance and postoperative pain was analyzed using the Mann-Whitney U test and the Fisher exact test. Statistical analysis was performed using the SPSS version 28.0 software. RESULTS: A total of 30 male patients with a mean age of 22.5 ± 4.8 years were included in our study. In the group with low pain tolerance, the pain scores at the first 2 hours, 32, and 48 hours after the operation (4.55 ± 3.59, 2.91 ± 2.59, 2.91 ± 2.43, respectively) were found to be significantly higher than the group with high pain tolerance (2.00 ± 2.67, 0.95 ± 1.68, 0.95 ± 1.39, respectively) (P < .05). In the first 2 hours after the operation, the amount of ibuprofen consumed was also significantly higher in the group with low pain tolerance compared to the other group, and 81.8% of this group felt the need to consume ibuprofen (P < .05). CONCLUSIONS AND RELEVANCE: The cold pack test, a more practical version of quantitative sensory testing, is useful in identifying male patients at risk of developing greater pain after third molar surgery. It can be helpful to provide effective analgesia in male patients with different pain tolerance thresholds.

Anthropometric and laboratory parameter alterations following bimaxillary orthognathic surgery.

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.
