Introduction
Effective surgical access to the orbital floor facilitates surgery and mitigates postoperative complications (PC). The aim of this study was to compare PC between the preseptal and retroseptal transconjunctival approaches (PS-TCA/RS-TCA) for isolated orbital floor fracture (OFF).
Materials and Methods
Using a double-blind, non-inferiority, randomized, split-face study design, patients aged ≥ 18 years with bilateral isolated OFF were enrolled. A sample size of 177 eyes per group was determined through power analysis. The primary predictor variable was the surgical approach, and the main outcome was the PC rate at month 6. Statistical analyses were computed with a significance level at 0.05 and the non-inferiority margin at a relative risk (RR) of 0.045.
Results
The final sample included 193 patients (23.3 % female; age, 42.8 ± 18.1 years). Both TCA variants exhibited comparable PC rates (5.2 % for PS-TCA vs. 7.3 % for RS-TCA; P = 0.53; absolute risk, +2.07 % [95 % CI, -2.74 % to 6.89 %]; RR, 1.4 [95 % CI, 0.64 to 3.07]). Approximately one in every 49 patients experiencing PC with RS-TCA (number needed to harm, 48.3).
Conclusions
Both TCA methods can be used without different PC rates at 6 months postoperatively. Future research should focus on TCA in combination with other surgical approaches for multiple orbital wall reconstruction.
导言：有效的眶底手术入路有助于手术的顺利进行并减少术后并发症（PC）。本研究旨在比较经结膜前路和经结膜后路（PS-TCA/RS-TCA）治疗孤立性眶底骨折（OFF）的PC情况：采用双盲、非劣效、随机、分面研究设计，招募年龄≥ 18 岁的双侧孤立性眶底骨折（OFF）患者。通过功率分析确定每组样本量为 177 只眼睛。统计分析的显著性水平为 0.05，非劣效边际相对风险（RR）为 0.045：最终样本包括 193 名患者（23.3% 为女性；年龄为 42.8±18.1 岁）。两种 TCA 变体的 PC 发生率相当（PS-TCA 为 5.2% vs. RS-TCA 为 7.3%；P = 0.53；绝对风险为 +2.07% [95% CI, -2.74% to 6.89%]；RR 为 1.4 [95% CI, 0.64 to 3.07]）。大约每 49 名患者中就有一人使用 RS-TCA 进行 PC 治疗（伤害所需人数为 48.3）：两种 TCA 方法在术后 6 个月的 PC 发生率并无差异。未来的研究重点应放在 TCA 与其他手术方法相结合的多眶壁重建上。

Injuries and deaths from crossbows are uncommon, especially when self-inflicted. We present here the case of a 45 years old patient with history of mental illness, who attempted suicide with a crossbow. The bolt penetrated the chin, crossed the oral floor, the oral cavity, the bony palate, the left nasal cavity and exited at the level of the nasal bones.
The main concern was the management of the airways, before proceeding to the removal of the bolt. A nasotracheal intubation through the right nasal cavity while the patient was conscious was performed, but the instruments needed for an emergency tracheotomy were in the operating room in case of failure. The intubation was successful, he underwent general anesthesia, and the bolt was removed from the face.

Objective
Bell's palsy, also referred to as clinical manifestations of unilateral facial nerve palsy, encompasses downward angling of the corners of the mouth, the absence of forehead creases, and unilateral incomplete eyelid closure. The incidence of Bell's palsy has increased progressively in recent years, but the underlying mechanism of its occurrence remains unknown; therefore, it is essential to investigate both the cause and treatment of Bell's palsy. Member 2 of the Subfamily V Transient Receptor Potential Cation Channel is a mechanically and thermally sensitive ion channel that plays a crucial role in neural growth and development. Using a novel modeling technique, we endeavored to develop an animal model of Bell's palsy and determine whether TRPV2 expression is altered throughout the course of a facial nerve injury.
Materials and methods
The rats were categorized into 3 groups, and their facial nerve function was assessed using RT-qPCR, WB, and pathologic testing, respectively, after undergoing unilateral cold air stimulation for 1, 3, and 7 days. TRPV2 expression was identified using these techniques.
Results
In response to cold stimulation, rats exhibited facial nerve paralysis symptoms, demyelinating lesions in the facial nerve, and increased TRPV2 expression.
Conclusions
Extended cold stimulation of the facial nerve in rats may lead to an imbalance in facial nerve homeostasis and increased TRPV2 expression. These findings will contribute to the understanding of the potential mechanism by which cold stimulation affects the facial nerve. Moreover, this finding implies that TRPV2 could possibly function as an additional diagnostic marker or therapeutic target in the context of Bell's palsy.

Oral cavity metastasis from renal cell carcinoma is rare with poor prognosis. Recently immune checkpoint inhibitors (ICIs) have shown promising outcomes in the treatment of advanced RCC. Herein, we report a case of palatal lesion mimicking vascular tumor in a 60-year-old woman with locally advanced kidney cancer (T3aN0M0). She underwent an excisional biopsy, and histopathological examinations revealed an oral metastasis from clear cell renal cell carcinoma (ccRCC). The patient was treated with a combination of two ICIs with nivolumab, a programmed death 1 (PD-1), and ipilimumab, a cytotoxic T-lymphocyte-associated antigen 4 (CTLA4). After 3 cycles of systemic immunotherapy, the palate was completely well healed and after 13 months of follow-up, there was no evidence of recurrence. Regarding treatments, radical surgery is often recommended due to a high local control in case of solitary lesions or oligo-metastases. However, this option therapy is associated with a poor quality of life. To the best of our knowledge, this is the first case to suggest the benefits of ICIs in the treatment of oral metastases from ccRCC. Combining ICIs with conservative surgery could be another treatment option for oral metastasis in patients with renal cell carcinoma.

Objectives
The aim of this study is to presents an experimental method for surgical guide confection using an intraoral scanner to obtain a 3D model of the patient's complete denture and compare its accuracy with the conventional methodology using computed tomography.
Study design
This prospective in-vitro study used 30 polyurethane pre-manufactured mandibles which were divided into two groups, conventional technique (group I) and a new method using intraoral scanner (group II), establishing the virtually planned position of the dental implants as a control group, considered as the gold standard for postoperative comparison.
Results
The difference between these methods is close to zero and not statistically significant (p > 0.05), being heigh deviation (Xh) with p:0.130 and angulation difference of dental implants between the groups (Ang) with p:0.396.
Conclusion
The acquisition of stereolithography image of the prosthesis using an intraoral scanner has a clinically acceptable accuracy, being in agreement with the conventional method.

Polyacrylamide hydrogel (PAAG) is widely regarded as a safe soft tissue filler and has been extensively utilized for cosmetic enhancements, such as breast and facial augmentation in China from 1997 until its ban in 2006. Common complications associated with its use include inflammation, infection, granulomas, fibrosis, gel migration, and facial and soft tissue deformities. This case report describes a 45-year-old Chinese woman who experienced PAAG migration into her mandible 24 years after facial augmentation, causing irritation of the mandibular alveolar nerve - apparently the first documented instance of this occurrence. Surgical intervention was necessary to remove the migrated gel and associated calcifications. A literature review explored adverse events and management strategies for PAAG complications in cosmetic procedures. While generally considered safe, this report underscores the importance of meticulous injection techniques and careful anatomical site selection to prevent such severe complications.

Introduction
Oral squamous cell carcinomas (OSCC) seen in the oral cavity are a category of diseases for which dentists may diagnose and even cure. This study evaluated the performance of diagnostic computer software developed to detect oral cancer lesions in intra-oral retrospective patient images.
Materials and methods
Oral cancer lesions were labeled with CranioCatch labeling program (CranioCatch, Eskişehir, Turkey) and polygonal type labeling method on a total of 65 anonymous retrospective intraoral patient images of oral mucosa that were diagnosed with oral cancer histopathologically by incisional biopsy from individuals in our clinic. All images have been rechecked and verified by experienced experts. This data set was divided into training (n = 53), validation (n = 6) and test (n = 6) sets. Artificial intelligence model was developed using YOLOv5 architecture, which is a deep learning approach. Model success was evaluated with confusion matrix.
Results
When the success rate in estimating the images reserved for the test not used in education was evaluated, the F1, sensitivity and precision results of the artificial intelligence model obtained using the YOLOv5 architecture were found to be 0.667, 0.667 and 0.667, respectively.
Conclusions
Our study reveals that OCSCC lesions carry discriminative visual appearances, which can be identified by deep learning algorithm. Artificial intelligence shows promise in the prediagnosis of oral cancer lesions. The success rates will increase in the training models of the data set that will be formed with more images.

Introduction
The aim of this 11-year retrospective multicentric study is to evaluate the policy of 14 maxillofacial surgery divisions in terms of titanium plate removal from paediatric patients who had undergone open reduction and internal fixation (ORIF) to treat maxillofacial fractures.
Material and methods
Patients ≤ 16 years undergoing surgical treatment for fractures of middle and lower third of the face between January 2011 and December 2022, with a minimum follow-up of 6 months, were included. Age (group A: ≤ 6 years, B: 7–12 years, C: 13–16 years), sex, fracture location and type, surgical approach, number, and location of positioned and removed plates, timing and indications for removal were recorded.
Results
191/383 (50 %) patients (median age, 10 years; M:F ratio 2.1:1) underwent removal of 319/708 (45 %) plates. Maxillary dentoalveolar process (91 %), angle/ramus (63 %) and mandibular body (61 %) had a significantly higher removal rate than other fracture sites (p < 0.001). A significant decreasing trend in removal with increasing age was observed, from 83 % in Group A to 24 % in Group C (p < 0.001). On the total of positioned plates, 11 % were removed for symptomatic reasons (5 % infections, 6 % discomfort/pain) and 34 % for other reasons (28 % scheduled removal).
Discussion
This multicentric study showed that plate removal was not performed routinely in the paediatric population. The incidence and causes of symptomatic plates removal were consistent with the literature, while the plate removal rate from asymptomatic patients was lower. A correlation was found between increasing age and a reduction in the frequency of plate removal procedures.

Age (group A: ≤ 6 years, B: 7–12 years, C: 13–16 years), sex, fracture location and type, surgical approach, number, and location of positioned and removed plates, timing and indications for removal were recorded.</div></div><div><h3>Results</h3><div>191/383 (50 %) patients (median age, 10 years; M:F ratio 2.1:1) underwent removal of 319/708 (45 %) plates. Maxillary dentoalveolar process (91 %), angle/ramus (63 %) and mandibular body (61 %) had a significantly higher removal rate than other fracture sites (<em>p</em> < 0.001). A significant decreasing trend in removal with increasing age was observed, from 83 % in Group A to 24 % in Group C (<em>p</em> < 0.001). On the total of positioned plates, 11 % were removed for symptomatic reasons (5 % infections, 6 % discomfort/pain) and 34 % for other reasons (28 % scheduled removal).</div></div><div><h3>Discussion</h3><div>This multicentric study showed that plate removal was not performed routinely in the paediatric population. The incidence and causes of symptomatic plates removal were consistent with the literature, while the plate removal rate from asymptomatic patients was lower. A correlation was found between increasing age and a reduction in the frequency of plate removal procedures.</div></div>","PeriodicalId":55993,"journal":{"name":"Journal of Stomatology Oral and Maxillofacial Surgery","volume":"125 5","pages":"Article 101986"},"PeriodicalIF":1.8,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141790072","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
