RESUMO
BACKGROUND: In the evolving field of maxillofacial surgery, integrating advanced technologies like Large Language Models (LLMs) into medical practices, especially for trauma triage, presents a promising yet largely unexplored potential. This study aimed to evaluate the feasibility of using LLMs for triaging complex maxillofacial trauma cases by comparing their performance against the expertise of a tertiary referral center. METHODS: Utilizing a comprehensive review of patient records in a tertiary referral center over a year-long period, standardized prompts detailing patient demographics, injury characteristics, and medical histories were created. These prompts were used to assess the triage suggestions of ChatGPT 4.0 and Google GEMINI against the center's recommendations, supplemented by evaluating the AI's performance using the QAMAI and AIPI questionnaires. RESULTS: The results in 10 cases of major maxillofacial trauma indicated moderate agreement rates between LLM recommendations and the referral center, with some variances in the suggestion of appropriate examinations (70% ChatGPT and 50% GEMINI) and treatment plans (60% ChatGPT and 45% GEMINI). Notably, the study found no statistically significant differences in several areas of the questionnaires, except in the diagnosis accuracy (GEMINI: 3.30, ChatGPT: 2.30; p = 0.032) and relevance of the recommendations (GEMINI: 2.90, ChatGPT: 3.50; p = 0.021). A Spearman correlation analysis highlighted significant correlations within the two questionnaires, specifically between the QAMAI total score and AIPI treatment scores (rho = 0.767, p = 0.010). CONCLUSIONS: This exploratory investigation underscores the potential of LLMs in enhancing clinical decision making for maxillofacial trauma cases, indicating a need for further research to refine their application in healthcare settings.
RESUMO
PURPOSE: This pilot study aims to evaluate the feasibility and effectiveness of computer-assisted surgery protocol with 3D-preformed orbital titanium mesh (3D-POTM), using presurgical virtual planning and intraoperative navigation in primary inferomedial orbital fracture reconstruction. METHODS: Between March 2021 and March 2023, perioperative data of patients undergoing surgery for unilateral inferomedial orbital fracture treated with 3D-POTM were analyzed. Presurgical virtual planning with a Standard Triangle Language file of preformed mesh was conducted using the mirrored unaffected contralateral side as a reference, and intraoperative navigation was used. The reconstruction accuracy was determined by: correspondence between postoperative reconstruction mesh position with presurgical virtual planning and difference among the reconstructed and the unaffected orbital volume. Pre- and postoperative diplopia and enophthalmos were assessed. RESULTS: Twenty-six patients were included. Isolated orbital floor fracture was reported in 14 (53.8%) patients, meanwhile medial wall and floor one in 12 (46.1%) cases. The mean difference between final plate position and ideal digital plan was 0.692 mm (95% CI: 0.601-0.783). The mean volume difference between reconstructed and unaffected orbit was 1.02 mL (95% CI: 0.451-1.589). Preoperative diplopia was settled out in all cases and enophthalmos in 19 (76.2%) of 21 patients. CONCLUSION: The proposed protocol is an adaptable and reliable workflow for the early treatment of inferomedial orbital fractures. It enables precise preoperative planning and intraoperative procedures, mitigating pitfalls and complications, and delivering excellent reconstruction, all while maintaining reasonable costs and commitment times.

RESUMO
This study aimed to compare the accuracy of inferomedial orbital fracture restoration using customized orbital implant versus 3D preformed titanium mesh. Patients were divided into two groups. Group 1 underwent surgery with customized orbital implants and intraoperative navigation, while group 2 was treated using 3D preformed titanium meshes with preoperative virtual surgical planning (VSP) and intraoperative navigation. Reconstruction accuracy was assessed by: (1) comparing the postoperative reconstruction mesh position with the preoperative VSP; and (2) measuring the difference between the reconstructed and unaffected orbital volume. Pre- and postoperative diplopia and enophthalmos were also evaluated. Fifty-two patients were enrolled (25 in group 1 vs 27 in group 2). The mean difference between final plate position and ideal digital plan was 0.62 mm (SD = 0.235) in group 1 and 0.69 mm (SD = 0.246) in group 2, with no statistical difference between the groups (p = 0.282). The mean volume differences between the reconstructed and unaffected orbits were 0.95 ml and 1.02 ml in group 1 and group 2, respectively, with no significant difference between the groups (p = 0.860). Overall clinical improvements, as well as complications, were similar. 3D preformed titanium meshes can reconstruct inferomedial fractures with the same accuracy as customized implants. Therefore, in clinical practice, it is recommended to use 3D preformed meshes for this type of fracture due to their excellent results and the potential for reducing time and costs.

The present study investigates the impact of the COVID-19 pandemic on the management of Non-Melanoma Skin Cancer (NMSC) in the head and neck region. Conducted at the University Hospital "Le Scotte" in Siena, Italy, the research includes 111 patients treated from 2018 to 2021. The study aims to understand how pandemic-related healthcare changes affected NMSC treatment, focusing on differences in diagnosis and management before and during the pandemic. Methods involved retrospective analysis of patient demographics, clinical characteristics, lesion details, and treatment modalities, using Jamovi software (version 1.6) for statistical analysis. Results revealed the scalp as the most common NMSC site, with Squamous Cell Carcinoma (SCC) being the predominant histotype. A significant rise in Basal Cell Carcinoma (BCC) cases and a reduction in surgery duration were noted during the pandemic. The shift to local anesthesia was more pronounced, reflecting the necessity to adapt to healthcare limitations. Despite the disruptions caused by the pandemic, there was no significant drop in NMSC cases, which is attributed to the noticeable nature of head and neck lesions. In conclusion, this study highlights that the COVID-19 pandemic significantly influenced surgical practices in NMSC management, emphasizing the need for effective healthcare strategies that balance quality patient care with public health safety measures.
RESUMO
BACKGROUND: Chondrodermatitis nodularis helicis is a benign, but painful inflammatory condition of the ear, characterised by a tender nodule located on the helix or antihelix. This study aimed to investigate the occurrence of chondrodermatitis nodularis helicis associated with the use of coronavirus disease 2019 masks during the pandemic. METHOD: A retrospective single-centre study was performed from February 2020 to February 2022 in the Maxillo-Facial Unit at the University Hospital of Siena, Italy. RESULTS: During the indexed period, 11 patients were affected by chondrodermatitis nodularis helicis. All patients wore a mask for more than 8 hours a day, every day for several months. CONCLUSION: Although there is no certain proof of the correlation between masks and chondrodermatitis nodularis helicis, an increase in the incidence of this condition was highlighted in our single-centre experience in the pandemic period. The prolonged use of coronavirus disease 2019 masks may explain this correlation.

Preoperative computer-assisted planning and intraoperative navigation are becoming popular for orbital fracture treatment. However, not all institutions currently have access to these computer-aided applications. The authors present a simple and intuitive operative algorithm to guide orbital fracture reconstructions. The operative algorithm was based on linear measurements of orbital defects on high-resolution Computer tomography (CT) scans using specific axial, coronal, and sagittal plane images. The fractures were then divided into 3 types based on site and defect-size area. For each type, the authors suggested a surgical approach and material reconstruction. Between February 2022 and January 2023, 57 patients were treated according to the described CT-based protocol. The quality of reconstruction was classified as ideal, satisfactory, acceptable, and poor based on postoperative CT. Diplopia, enophthalmos, and postoperative complications were assessed. Fifty-seven patients were included. Forty-four (77.2%) patients were included in the type 1 group, 4 (7.01%) in the type 2 group, and 9 (15.79%) in the type 3 group. The reconstruction was considered ideal in 54 (94.7%) cases, satisfactory in 2 (3.5%), and acceptable in 1 (1.8%). No revision surgery was required. In all cases, preoperative diplopia was settled out, and only 1 patient reported postoperative enophthalmos. No complications occurred, with good clinical results and orbital symmetry. The linear CT measurement-based protocol is a simple and reliable workflow to guide the surgeon's choice of reconstruction material and surgical approach for primary orbital reconstruction. It allows good management of orbital trauma and could help standardize treatment decisions with an imaging technique available in all institutions.

Traditional osteotomic procedures can fail to restore the natural appearance of the face and can sometimes highlight the intrinsic decrease in the volume of soft tissues; in these cases, soft-tissue-improving procedures should be considered. The authors describe a new strategy that can help redistribute facial soft tissues and enhance facial esthetics in orthognathic surgery using a pedicled buccal fat flap to increase the volume of the malar soft tissue envelope. Between January 2017 and January 2021, 47 patients with dentoskeletal deformity who needed to increase the projection of the cheekbone contour underwent orthognathic surgery with simultaneous pedicled buccal fat pad flap for malar augmentation. Preoperative and postoperative facial appearance was evaluated by clinical examination and analysis of photographs to assess the occlusal and esthetic outcomes. A patient questionnaire was used to assess self-evaluation satisfaction scores. A good projection of the cheekbone contour was obtained, and noticeable postoperative facial esthetic improvement was observed in all patients. The overall esthetic improvement was considered "excellent" by 89.36% of patients, and facial esthetic improvement was assessed as "very much improved" or "much improved" by the clinicians in 95.7% of cases. The buccal fat pad flap is a promising and easy technique in orthognathic surgery that helps harmonize the malar region; improve esthetic outcomes with predictable and lasting long-term stability; and ensure very low morbidity and great esthetic satisfaction.

In the palatal defects due to surgical resection, flap selection is very important for a correct reconstruction. Different methods have been suggested over the time, however the pedicled buccal fat pad is a simple, effective, reliable flap for reconstruction after palate tumor resection. The aim of the present study is to introduce a new surgical technique for palate reconstruction with pedicled buccal fat pad flap exposing the advantages. The Authors performed this procedure in 17 patients in order to treat medium-sized oncologic surgical defect of palate region in the period between 2016 and 2019. Complete wound healing after only 4 weeks without complication after 12 months follow-up was observed. This is the first cases series described with this new technique.
RESUMO
ABSTRACT: Combined orbital medial wall and floor fractures and large isolated orbital floor fractures commonly require surgical treatment due to the high probability of diplopia and enophthal-mos. Primary reconstruction of these orbital fractures requires a high-level surgeon with a great amount of technical surgical skill. The use of novel technology can greatly improve the accuracy of reconstruction and achieve satisfactory clinical outcomes. Hence, the authors aimed to present our findings and overall experience with respect to extensive floor and medial wall orbital fracture reconstruction according to the Computerized Operation Neuronavigated Surgery Orbital Recent Trauma (CONSORT) protocol, a workflow designed for the primary reconstruction of orbital fractures with customized mesh and intraoperative navigation. A total of 25 consecutively presenting patients presenting with unilateral extensive orbital floor fractures and orbital floor and medial wall fractures were treated following the CONSORT workflow from January 2017 to March 2020. Fractures were surgically treated with a customized implant and intraoperative navigation. Patients underwent surgery within 14âdays of the trauma injury. Preopera-tive and postoperative functional and aesthetic outcomes are described herein. All fractures were successfully reconstructed. Postoperatively, all 19 patients with preoperative diplopia reported the resolution of diplopia. Enophthalmos resolved in 18/20 cases. No patients had major complications during follow-up. Thus, the authors conclude that the CONSORT protocol introduced by the authors is an adaptable and reliable workflow for the early treatment of orbital fractures and can clearly optimize functional and aesthetic outcomes, reduce costs and intensive time commitments, and make customized and navigated surgery more available for institutions.

BACKGROUND: Reconstruction of palate defects following tumor ablative surgery can be a challenging problem. Different methods have been suggested over the time for the reconstruction of postoperative palatal defects. Since the first report of the Bichat fat pad flap in1977, it has become one of the most used flaps for the reconstruction of palate after tumor excision. We report our results using the tunnellized Bichat fat pad (BFP) flap for 23 cases of palate reconstruction after minor salivary glands tumor excision. METHODS: The authors performed a tunnellized Bichat fat pad flap for primary reconstruction of small- medium-sized surgical defects of the palate in 23 patients suffering from minor salivary glands palatal tumors in the period between 2016 and 2019. Each case was reviewed for primary pathologic findings, wound healing, postoperative complications. RESULTS: All 23 tunnellized BFP procedures showed excellent recovery and uneventful follow-up. With this technique after 12 months follow-up complete wound healing after only 4 weeks without complication was observed. CONCLUSIONS: The tunnellized BFP flap is useful, easy, and uncomplicated new alternative method for primary reconstruction of small to medium-sized palatal surgical defects, that can be performed with a very low morbidity. Submucosal tunnel for the pedicle passage introduced by the Authors adds some advantages in final outcomes with less discomfort for the patients, proving to be a technique able to adds itself to surgical reconstructive technique available today.
