The primary outcome of interest was reporting of the CI. Descriptive and bivariate statistics were computed. A P value of ≤ .05 was considered significant. RESULTS The sample included 102 reports. The P value was uniformly reported (100%) in all 102 publications. CIs were reported in 29 reports (28.4%; 95% CI, 19.9 to 38.2). The OMS focus area was associated with reporting CIs (P = .02). Anesthesia/facial pain studies were significantly less likely to report the CIs (12.0%) compared with studies of craniomaxillofacial deformities (100%; Bonferroni P = .02). No other significant associations were found between the predictors and CI reporting (P ≥ .08). CONCLUSIONS CIs have been reported in a small proportion of RCTs within OMS. Given the shortcomings of reporting only the P values, a significant need exists for improving the statistical reporting standards among OMS journals. PURPOSE Esthetic dental and skeletal component correction can affect the temporomandibular joint (TMJ). Arthrogenic TMJ dysfunction can be present in the joint at the outset or it can develop during the treatment or later. The aim of the present study was to examine the changes found on magnetic resonance imaging (MRI) studies of the TMJ in patients with skeletal Class II malocclusion who had undergone combined orthodontic and bilateral sagittal split ramus osteotomy (BSSRO) advancement. Our objective was to measure the changes in the disc position, condylar translation, secondary bony changes, and joint effusion on MRI before and after treatment. MATERIALS AND METHODS An analytical, single-surgeon, single-institution, retrospective radiological (MRI) study was designed. We included patients who had undergone combined orthodontic and BSSRO advancement from 2011 to 2018. All 36 patients were examined using a 1.5-Tesla MRI unit (Siemens Symphony, Erlangen, Germany) with a 6 × 8-cm diameter surface coil, which allowed for simultaneous imaging of both TMJs. RESULTS Analysis using the Wilcoxon signed rank test revealed statistically significant differences in the pre- and post-treatment groups in the changes in the position of the disc from anterior disc displacement with reduction (ADDWR) to the normal position (P = .008), condylar translation from excessive to normal (P = .046), and an increase in secondary bony changes (P = .005). CONCLUSIONS Combined orthodontic and orthognathic movement in the treatment of skeletal Class II malocclusion can increase secondary bony changes, improve the disc position in ADDWR cases, and control excessive translation of the TMJ. No improvement was noted in the position of the disc in those with anterior disc displacement without reduction, hypomobility and joint effusion. PURPOSE Zygomaticomaxillary complex (ZMC) fractures occur often. However, no clinical consensus has been reached regarding the number of fixation points required when performing open reduction and internal fixation (ORIF). The objective of the present study was to explore the utility of single-point fixation in the management of noncomminuted ZMC fractures. PATIENTS AND METHODS We analyzed the data from a retrospective case series of 211 patients treated during a 20-year period. RESULTS The mean length of follow-up was 3.4 months. Of the 211 patients, 162 with noncomminuted ZMC fractures had been treated with single-point fixation of the zygomaticomaxillary buttress. During the follow-up period, 1 patient experienced tooth loss because of a root present in the fracture line, 7 experienced intraoral plate exposure, with 2 subsequently undergoing plate exchange, and 8 developed a wound infection. No patients required orthognathic surgery or cheek implants for malar asymmetry. https://www.selleckchem.com/products/1400w.html No patient developed hypoglobus or enophthalmos, and none required revision ORIF of their ZMC fracture. CONCLUSIONS To the best of our knowledge, the present study represents the largest series in the literature reporting the surgical results and outcomes of patients with noncomminuted ZMC fractures treated with single-point fixation. In experienced hands, we believe this is a viable surgical option if appropriate surgical considerations are made. PURPOSE Cone-beam computed tomography (CBCT) is commonly requested before dental implant treatment for the anatomic assessment of the inferior alveolar canal (IAC) to prevent its neurovascular content from being traumatized. CBCT images can be saved in different types of resolutions and bit depths; these parameters may significantly affect the diagnostic accuracy of images. This study aimed to assess the effect of resolution and bit depth on IAC visualization on exported mandibular CBCT images. MATERIALS AND METHODS Forty-one mandibular CBCT images of differing image resolutions and voxel sizes (0.16, 0.32, and 0.48 mm) and differing bit depths (12 and 15) were exported from a software program as a single file. Two observers evaluated the cross-sectional images in terms of IAC visibility using a 3-point scale (good, moderate, and poor). Disagreements were resolved by including a third observer, and the highest agreement was recorded. RESULTS Study interobserver agreement was acceptable (84.2%) for IAC observation. The percentage of IAC observation was from 84.1 to 100% with the 12- and 15-bit depths, with a constant image resolution of 0.16 and 0.32 mm, respectively. A significant difference (from 19.5 to 48.8%) was noted between the 2 bit depths in the percentage of good IAC visualization with a constant resolution of 0.48 mm. Reduction in the image resolution to 0.48 mm showed a significant difference (19.5 to 100%) between the 12- and 15-bit depths in good IAC visualization. CONCLUSIONS Exporting the mandibular CBCT images with 0.32 mm of resolution and a 12-bit depth will produce good and moderate radiographic IAC observation with the benefit of a smaller file size. PURPOSE The application of bio-resorbable plates in craniomaxillofacial surgery is increasing because of the advantage of avoiding secondary surgery. This study aimed to evaluate the effects of osteosynthesis with prebent bio-resorbable plates for treating zygomaticomaxillary complex (ZMC) fractures. MATERIALS AND METHODS We implemented a prospective case series composed of patients with ZMC fractures who underwent treatment at the School of Stomatology at China Medical University. Bio-resorbable plates were used for fracture fixation. The fractures were stabilized with bio-resorbable plates prebent on a 3-dimensionally printed skull model with the fractures reduced using virtual simulation. The primary outcome variable was the stability rate of reduced bone segments. Other study variables were mouth opening, occlusion, paresthesia or anesthesia in the infraorbital nerve region (PAIN), and diplopia. Outcome variables were determined by calculating stability rates of reduced bone segments, resolution rates of postoperative restricted mouth opening, malocclusion, PAIN, and diplopia.
