Background: Bimaxillary (BiMax) advancement surgeries are one of the most frequently performed procedures in the orthognathic subspecialty of craniomaxillofacial surgery. The growing digitalization of the planning process and the shift from physical to virtual settings in procedure design have allowed, among other things, for better visualization of surgeries, improved preparation, and a more profound understanding of individual anatomy. Therefore, the question of the accuracy of performed virtual planning (VP) as well as the available methods of its evaluation arises naturally. The aim of this study was to determine the accuracy of performed BiMax advancement surgeries and propose a new planning accuracy coefficient (PAC). Methods: A group of 35 patients who underwent BiMax surgery were included in the study. Computed tomography (CT) of the head and neck region was performed 2 weeks preoperatively and 6 months postoperatively. Acquired Digital Imaging and Communications in Medicine (DICOM) files were used to perform a VP and a 3-dimensional (3D) cephalometry analysis using IPS CASE DESIGNER® software, v2.5.7.1 (KLS Martin Group, Tuttlingen, Germany). Statistical significance evaluation and basic measures of central tendency and dispersion of the analyzed variables were calculated. The accuracy of the performed planning was assessed based on the mean absolute error (MAE) between the planned and achieved cephalometric data variables. Additional assessment was performed based on the proposed PAC. Results: VP was found to be accurate in terms of cephalometric data assessing the height of the maxilla and mandible, the inclination of the occlusal plane, the position of the jaws in relation to the skull base, as well as overjet and overbite. There was a discrepancy in results between the classic and proposed methods of accuracy assessment in the case of several of the evaluated variables. Conclusions: The accuracy of the VP of BiMax advancement surgeries can be evaluated based on 3D cephalometry, and it is accurate in the assessment of the previously mentioned variables. There is a need for further analysis and potential development of the proposed PAC; however, the data obtained based on PAC are promising, and by taking into account the magnitude of planned movements, it can facilitate a fair comparison of results presented in different studies based on various assessment methods.

Background/Objectives: Oral health is critical for overall health, particularly in hospitalized patients whose weakened physical state can lead to oral changes, such as dry mouth and gingivitis due to anxiety and stress. Neglected oral hygiene can lead to infections and systemic complications. This study aims to evaluate the antibacterial efficacy of low-frequency square-wave positive voltage electrical stimulation compared to chlorhexidine and to assess its potential as a next-generation solution for preventing hospital-acquired infections. Methods: Sixty-three tooth specimens were randomly assigned to seven groups, including various concentrations of chlorhexidine and electrical stimulation with or without brushing. Biofilm formation was induced using saliva from healthy donors and standard strains of Streptococcus mutans and Aggregatibactor actinomycetemcomitans. Bacterial colony-forming units (CFU) and absorbance changes were measured post-treatment. Results: Significant reductions in CFU counts were observed in both the chlorhexidine and electrical stimulation groups compared to the control, with the 5V2H group showing superior antibacterial efficacy over 0.12% chlorhexidine. Chlorhexidine-treated specimens demonstrated a dose-dependent response and minimal bacterial presence, while electrical stimulation showed effectiveness but with re-growth observed after 4 h. Scanning electron microscopy revealed substantial biofilm on untreated and electrically stimulated specimens, whereas chlorhexidine-treated specimens exhibited minimal bacterial presence. Conclusions: Intermittent electrical stimulation shows promise as an alternative to chlorhexidine for oral hygiene management in critical care settings, though an optimization of electrical parameters is necessary for sustained effects. This approach could reduce hospital-acquired infections by providing an effective, non-chemical method for maintaining oral hygiene. Full article

Background: When defects occur in the lips due to conditions such as lip cancer, it is essential to reconstruct them both functionally and aesthetically, given the vital roles that lips play in communication, nutrition, and overall appearance. Various flap techniques are available for lip reconstruction, and the surgical method should be chosen based on the location and extent of the defect. Methods: This article discusses two cases of successful lip reconstruction using a combination of the Abbe flap and additional flaps, tailored to the extent of the defects. In case 1, a 52-year-old female diagnosed with angiosarcoma underwent a wide resection of 1/3 to 2/3 of her upper lip. Reconstruction was performed using an Abbe flap combined with a perialar crescentic flap. In case 2, a 54-year-old male with squamous cell carcinoma had more than 2/3 of his lower lip excised. Although the Bernard–Burrow–Webster flap is typically used for such cases, the patient was reconstructed with an Abbe flap combined with a staircase flap, addressing the limitations of traditional methods. Results: Both reconstruction surgeries achieved excellent aesthetic and functional outcomes. In case 1, the combination of the Abbe flap and perialar crescentic flap provided the patient with a natural appearance and preserved lip functionality. In case 2, the Abbe flap and staircase flap technique effectively restored lip function while avoiding complications such as microstomia and surgical scars associated with more conventional methods. Conclusions: The findings underscore that using the Abbe flap in combination with the perialar crescentic advancement flap or staircase flap can effectively restore both the functional and aesthetic integrity of the lips, particularly in cases involving significant tissue loss.

Objectives: This review aimed to evaluate the role of ChatGPT in original research articles within the field of oral and maxillofacial surgery (OMS), focusing on its applications, limitations, and future directions. Methods: A literature search was conducted in PubMed using predefined search terms and Boolean operators to identify original research articles utilizing ChatGPT published up to October 2024. The selection process involved screening studies based on their relevance to OMS and ChatGPT applications, with 26 articles meeting the final inclusion criteria. Results: ChatGPT has been applied in various OMS-related domains, including clinical decision support in real and virtual scenarios, patient and practitioner education, scientific writing and referencing, and its ability to answer licensing exam questions. As a clinical decision support tool, ChatGPT demonstrated moderate accuracy (approximately 70–80%). It showed moderate to high accuracy (up to 90%) in providing patient guidance and information. However, its reliability remains inconsistent across different applications, necessitating further evaluation. Conclusions: While ChatGPT presents potential benefits in OMS, particularly in supporting clinical decisions and improving access to medical information, it should not be regarded as a substitute for clinicians and must be used as an adjunct tool. Further validation studies and technological refinements are required to enhance its reliability and effectiveness in clinical and research settings. Full article
