Background:
Orthognathic surgery has become increasingly accurate with the integration of computerized technologies. This study aimed to evaluate the accuracy of custom-made plates in transferring the three-dimensional virtual plan to intraoperative maxillary repositioning.
Methods:
This study included 10 patients. A digital surgical simulation technique was used for preoperative planning. The surgical components— osteotomy/plates, locating guides, and customized titanium plates—were fabricated using computer-aided design and manufacturing techniques, replacing the need for a surgical splint. Postoperative outcomes were assessed using unaltered anatomical landmarks from the preoperative virtual plan. Absolute discrepancies in translational and rotational movements between the planned and actual postoperative positions were measured through superimposition analysis. This evaluation assessed the precision of custom-made plates in transferring the virtual surgical plan, identifying deviations in the cephalocaudal, mediolateral, and anteroposterior directions that could influence functional and esthetic outcomes.
Results:
No statistically significant differences were observed for any landmarks across the axial, coronal, and sagittal planes. The greatest variability was noted at the posterior nasal spine landmark in the axial plane (1.7 mm), compared with the coronal (0.9 mm) and sagittal (0.5 mm) planes.
Conclusion
Customized titanium plates effectively transferred the virtual surgical plan for maxillary repositioning without the need for an occlusal splint. However, potential posterior interference should be considered during surgical execution.

Purpose:
This study evaluated the sensitivity, specificity, and accuracy of computed tomographic angiography (CTA) versus handheld Doppler (HHD) in detecting perforators for anterolateral thigh (ALT) flap surgery.
Methods:
This study was conducted on 20 patients randomly assigned to two groups from April 2023 to November 2024: One group received CTA and HHD, while the other group received only HHD. Perforators were evaluated for their number, location, and source and compared with intraoperative findings.
Results:
The sensitivity and specificity of CTA were 86.0% and 98.0%, respectively, while those of HHD were 81.0% and 86.5%. CTA exhibited an accuracy of 92.0% for perforator identification, whereas that of HHD was 83.5%.
Conclusion
CTA offers higher sensitivity, specificity, and accuracy in identifying ALT flap perforators than HHD. Its superior imaging capabilities can enable improved surgical planning, minimizing intraoperative challenges, reducing the risk of complications, and potentially increasing flap survival rates. As such, CTA could be considered a valuable standard tool in preoperative planning for ALT flap surgery, particularly in cases where anatomical variation poses a challenge.

Dengue remains a public health threat that consumes a significant number of resources for its prevention and control. This systematic review aimed to solidify recent costing evidence in dengue management among South East Asian (SEA) countries. All studies conducted between 2010 and 2020 were retrieved using four international databases i.e. PubMed, Scopus, Web of Science, and Emerald Insight. The review was reported according to PRISMA guidelines. Quality assessments were done independently by two reviewers using a checklist adapted for the cost of illness studies. We identified 13 original articles representing several SEA countries. Among the common reported costing measure include total cost/ health expenditure; direct medical cost; direct non-medical cost; and indirect cost. The estimated total cost for dengue management varied between countries largely due to the difference in the total incidence of dengue cases. The estimated cost spent on dengue per capita GDP ranges from less than 0.001% to 0.1%, depending on the recorded number of dengue cases of the year. The majority of the articles focused on the economic burden from the perspective of treatment such as hospitalization and ambulatory care. In a nutshell, the economic burden of managing dengue infection is costly and the evidence suggests a steady increase in health expenditure with the growing number of dengue cases
