RESUMEN
BACKGROUND: Postoperative nausea and vomiting (PONV) is a common adverse side-effect following orthognathic surgery, with pain potentially contributing as a risk factor. PURPOSE: The study's purpose was to measure the association between postoperative pain and PONV. STUDY DESIGN, SETTING, SAMPLE: This prospective cohort study involved patients who underwent bimaxillary surgery at Erciyes University, Oral and Maxillofacial Surgery Hospital. Patients with a history of routine antiemetic use, pregnancy, breastfeeding, morbid obesity, cardiac dysrhythmia, mental retardation, or psychiatric illness were excluded. PREDICTOR/EXPOSURE/INDEPENDENT VARIABLE: The predictor variable was postoperative pain, which was measured using a 100-mm visual analogue scale (VAS). VAS scores were documented at the 30-minute postoperative mark (referred to as VAS1), and the mean of hourly VAS scores over the initial three postoperative hours (denoted as VAS2). MAIN OUTCOME VARIABLE(S): The primary outcome was the occurrence of PONV, defined as active vomiting, retching, or nausea leading to vomiting. The secondary outcome was the timing of PONV, categorized as early (within 6 hours), late (6-24 hours), and delayed (beyond 24 hours postoperatively). COVARIATES: The study's covariates were age, sex, body mass index, Apfel risk scores, surgery duration, history of PONV or motion sickness, and smoking status. ANALYSES: Descriptive statistics and χ2 tests were used for data analysis, with statistical significance set at P value < .05. RESULTS: The sample was composed of 86 subjects with a median age of 20 years (range: 18-30 years), of which 37.2% were male. The frequency of PONV was 50%. Postoperative pain, as measured by VAS scores, was significantly higher in the PONV group compared to the non-PONV group. The median VAS1 score was 60.0 (PONV group, range 40-90) versus 50.0 (non-PONV, range 0-90) (P = .041); for VAS2, it was 60.0 (PONV, range 40-80) compared to 40.0 (non-PONV, range 30-60) (P < .001). CONCLUSIONS AND RELEVANCE: The frequency of PONV observed in patients undergoing bimaxillary surgery is substantial, necessitating the identification and management of risk factors to enhance perioperative care and patient outcomes. By improving PONV management and addressing postoperative pain, health-care providers can enhance the perioperative experience and patient outcomes in bimaxillary surgery.

OBJECTIVE: To compare the efficacy of preemptive ibuprofen, local ketamine, and their combination in managing postoperative pain and trismus following third molar surgery. MATERIALS AND METHODS: One hundred patients were randomly divided into 4 groups. The Intrafen Group had their impacted third molars surgically removed under local anesthesia after receiving intravenous (IV) ibuprofen for preemptive effect. The Ketamine Group received an IV placebo before the surgery, and the extraction process was completed with a local anesthetic-ketamine combination. The Combined Group received preemptive IV ibuprofen before the procedure, and the surgery was performed with a local anesthetic-ketamine combination. The Control Group received an IV placebo before the procedure and then had their impacted third molars removed under local anesthesia. The Visual Analogue Scale (VAS) values, corresponding to the patients' pain levels at the 2nd and 12th postoperative hours and the total amount of analgesic dose used in the first 24 hours, were recorded, and evaluated. The maximum mouth opening of the patients was measured immediately before the procedure, and on the second and seventh postoperative days. The level of patient satisfaction in all groups was assessed during the procedure. RESULTS: The mean VAS value corresponding to the second-hour pain level of the combined group was statistically significantly lower than the other groups (Pâ¯=â¯.003). A statistically significant difference was found in the mean VAS values corresponding to the pain levels of the groups, favoring the combined group compared to the other groups (P ≤ .001). A significant difference was observed between the VAS difference values corresponding to the pain levels of the Intrafen group and the Ketamine group, favoring the Intrafen group (Pâ¯=â¯.038). The Ketamine group consumed the most analgesic on average over the first 24 hours, whereas the Combined group consumed the least. No statistically significant difference was found between the mean trismus levels of the groups on days 0-2 (Pâ¯=â¯.528) and days 0-7 (Pâ¯=â¯.129). The intraoperative patient satisfaction level of the combined group was significantly higher than that of the other groups (Pâ¯=â¯.030). CONCLUSION: Preemptive Intrafen is an effective regimen for postoperative pain management and is superior to the local anesthetic-ketamine regimen. The most effective method to reduce postoperative pain following third molar surgery is to use a combination of these 2 regimens. However, none of the treatment methods used in the study had a positive effect on postoperative trismus.

PURPOSE: To evaluate the efficacy of combined therapy of teriparatide and raloxifene on the osseointegration of titanium dental implants in a rabbit model of osteoporotic bone. MATERIALS AND METHODS: Sixty female rabbits were randomly divided into six groups. The sham ovariectomy group (control) consisted of animals that received no medication. Animals in the ovariectomy group (OVX) underwent ovariectomy and received no medication. The combined group consisted of ovariectomized animals that received combined teriparatide (10 mg/kg) for 12 weeks and raloxifene (10 mg/kg) for 12 weeks. The sequential group (SEQ) consisted of ovariectomized animals that received teriparatide (10 mg/kg) for the first 6 weeks and raloxifene therapy (10 mg/kg) for the following 6 weeks sequentially. The parathormone (PTH) and raloxifene (RAL) groups consisted of ovariectomized animals that received only teriparatide (10 mg/kg) for 12 weeks or raloxifene (10 mg/kg) for 12 weeks, respectively. Dental implants (Bilimplant) were placed in the proximal metaphysis of both tibias in all rabbits. Histomorphometric and microCT studies were performed on the specimens obtained from the right tibia bone. Removal torque (RTQ) and implant stability quotient (ISQ) tests were performed on the specimens obtained from the left tibia bone. The results were compared and evaluated statistically. RESULTS: RTQ analysis revealed a statistically significant difference between the mean values of the combined group (93.01 ± 27.19 Ncm) and the OVX group (49.6 ± 12.5 Ncm) (P = .015). The highest mean T0 (implantation day) value was obtained in the control group (67.1 ± 3.4 Ncm), and the lowest mean value was obtained in the OVX group (61.4 ± 3.8 Ncm). The highest T1 mean (3 months after implantation) was obtained by the combined group (76.6 ± 3.8 Ncm), and the lowest mean was obtained by the OVX group (68.9 ± 6.2 Ncm). Histomorphometric analyses showed that the mean percentage of bone-to-implant contact (BIC%) of the combined group (51.2%) was significantly higher than that of the OVX group (28.6%) (P =.006). In the microCT examinations, it was found that the mean BIC% value of the combined group (41.1%) was significantly higher than that of the OVX group (24.1%) (P < .001). CONCLUSIONS: According to the results of the current study, combined therapy of teriparatide and raloxifene improves the BIC and osseointegration of titanium dental implants in osteoporotic bone compared with sequential or independent therapy with these agents.

The purpose of this study was to elucidate the effects of mandibular anatomy and osteotomy technique on lingual fracture patterns in SSRO. The predictor variables were: length of horizontal medial osteotomy; type of border osteotomy; buccolingual width; and vertical length of the basal cortex. The outcome variable was the type of lingual split pattern. This was categorized into four types according to a lingual split scale (LSS): LSS 1, true Hunsuck; LSS 2, fracture line to posterior border of the ramus; LSS 3, through to mandibular canal; LSS 4, unfavorable fracture pattern. Data were analyzed using analysis of variance and the Pearson χ2 test. Values of p < 0.05 were considered statistically significant. The study sample comprised 312 lingual split patterns in 156 patients. The most common type of lingual split pattern was LSS 1 (n = 204). There was a significant relationship between inferior border osteotomy type and LSS type (p = 0.001). Whilst LSS 1 was the most common among all border osteotomy types. LSS 4 was most frequently observed in cases where the lower border osteotomy remained in the buccal surface. According to the results of this study, the likelihood of an unfavorable split pattern increases when the lower border osteotomy remains in the buccal surface.

Background: Although Le Fort I surgeries are safe and successful procedures; nasolacrimal duct injuries may be observed due to these surgeries. The study aimed to investigate the prevalence of nasolacrimal duct injury in Le Fort I osteotomy patients. Material and Methods: The authors conducted a retrospective cohort study consisting of patients who underwent Le Fort I osteotomies between 2017 and 2021 in the Erciyes University Faculty of Dentistry. The primary predictor variables were the distance of the nasolacrimal canal to the outer cortex of the maxilla and the nasal floor, as well as the superior-inferior level of the superiorly positioned screw inserted in the maxilla aperture region relative to the nasolacrimal canal. The outcome variable was the presence of a nasolacrimal duct injury. Mann Whitney U test was used for quantitative variables between the two groups. A Pearson chi-squared analysis was used to compare categorical data. A p-value <0.05 was considered statistically significant.Results: A total of 290 nasolacrimal canals were evaluated in 145 patients, 87 females, and 58 males. The mean age was 23.47± 6.67. There was a statistically significant relationship between screw level and nasolacrimal canal perforation (p<0,001). The distance between the most anterior border of the nasolacrimal canal and the outer cortical of the maxilla was significantly less in the perforation group (p<0,001). The fixation screw was significantly closer to the nasolacrimal canal in the perforation group (p<0,001). Conclusions: In Le Fort I surgery, nasolacrimal duct injury may occur during screw fixation to the aperture region. Superiorly positioned fixation screws in the aperture region may damage the nasolacrimal canal. In patients where the nasolacrimal canal is close to the outer cortex, care should be taken when applying the fixation screws to the aperture region to avoid damaging the canal.(AU)

Background: This study's purpose is to retrospectively evaluate the success of surgical methods used in treatingOroantral Communication (OAC).Material and Methods: This study was designed as a retrospective cohort study on patients who developed OACafter surgery maxillary posterior region. The records of patients previously treated with OAC were scannedthrough the hospital registry software. A data set was created by recording patients' age, gender, systemic dis-ease, etiological reasons, and surgical methods. The primary predictor variable was the surgical method usedto treat OAC. Other variables were age, gender, systemic disease and etiological reasons. The primary outcomewas oroantral fistula development after the first surgical intervention. The patients who were positive in clinicalexamination and Valsalva test on control days were considered unsuccessful. One-way analysis of variance andKruskal-Wallis tests were used for quantitative variables in more than two groups. Pearson chi-square test wasused to compare categorical data.Results: This retrospective cohort study was completed with 605 patients who met the study criteria among 95,883patients who underwent surgery in the maxillary posterior region. The incidence of OAC was 0.63%. The patientsconsisted of 238 female and 367 male patients. The mean age was 41.06±14.48 years. Buccal flap and Buccal FatPad methods were used most frequently in the treatment. While treatment was completed with the first surgicalintervention in 592 (97.85%) patients, OAF developed in 13 (2.15%) patients. No statistically significant relationexisted between surgical technique and OAF development (p>0.005). The success rate of the Buccal Flap methodwas 98.7%, and the Buccal Fat Pad method was 95.8%.(AU)

Background: The purpose of this study was to evaluate the effect of a single-dose intravenous dexketoprofen administration for preventive analgesia on postoperative pain and reducing swelling in double jaw surgery. Material and methods: The authors designed a prospective, randomized, and double-blind cohort study. Patients who have Class III malocclusion were randomly divided in two groups. 50 mg intravenous dexketoprofen trometamol were administrated 30 minutes before incision in treatment group, while intravenous sterile saline was administrated 30 minutes before incision in placebo group. The primary predictor variable was treatment group. Primary outcomes were pain, swelling and 24-hour opioid intake. Patient- controlled analgesia with tramadol was given for management of postoperative pain. Other variables were demographic and operation related parameters. Visual analogue scale was used to evaluate postoperative pain. 3dMD Face System (3dMD, USA) was used to measure postoperative swelling. Data were analysed using two independent samples t test and Mann Whitney U test. Results: The study sample was composed of 30 patients with a mean age of 20,63 years and 21 were female. Preemptive dexketoprofen administration decreased postoperative tramadol consumption by 25.9% compared to placebo group, and there was a statistically significant decrease in VAS scores (p<0,05). There was no statistically significant difference between the groups in terms of swelling (p>0,05). Conclusions: Preventive administration of intravenous dexketoprofen provides adequate analgesic effect in the postoperative 24-hour period and reduces opioid consumption in orthognathic surgery. (AU)
