Background

Cleft lip and/or palate (CL/P) is the most common congenital orofacial anomalies worldwide, with a multifactorial etiology involving both genetic and environmental factors. This study aimed to estimate the pooled prevalence of CL/P in Ethiopia and identify the associated risk factors.

Materials and Methods

We systematically searched PubMed, Scopus, and Google Scholar for studies published between 1990 and 2023. We included observational studies (cross-sectional, cohort, case–control, descriptive, and prospective) that reported prevalence data for CL/P in Ethiopia. Data were extracted using a standardized Excel form, and statistical analyses were conducted using STATA version 18. The primary outcome was the pooled prevalence of CL/P. Heterogeneity was assessed using Cochrane’s Q test and the I² statistic, and meta-analysis was performed using a random-effects model. The methodological quality of the studies was assessed using the STROBE checklist (version 2007).

Results

Across ten studies comprising 19,024,539 births, the pooled birth prevalence of CL/P in Ethiopia was 0.24 per 1000 live births (95 % CI: 0.12–0.36). Considerable heterogeneity was observed among studies (I² = 99.94 %, τ² = 0.04, Q = 8546.85, p < 0.001), reflecting substantial variability in prevalence estimates.

Conclusion

Although the prevalence of CL/P in Ethiopia is lower than the global average, it represents a significant public health concern. This underscores the need for strengthen preventive measures, promoting early detection, and expanding access to timely and comprehensive treatment services are essential for reducing the burden of these congenital anomalies.
背景:唇腭裂(clp)是世界范围内最常见的先天性口腔面部异常,其病因包括遗传和环境因素。本研究旨在估计埃塞俄比亚CL/P的总患病率,并确定相关的危险因素。材料和方法:我们系统地检索PubMed、Scopus和谷歌Scholar,检索1990年至2023年间发表的研究。我们纳入了观察性研究(横断面、队列、病例对照、描述性和前瞻性),这些研究报告了埃塞俄比亚CL/P的患病率数据。采用标准化Excel表格提取数据,使用STATA version 18进行统计分析。主要终点是CL/P的总患病率。采用Cochrane’s Q检验和I²统计量评估异质性,采用随机效应模型进行meta分析。使用STROBE检查表(2007版)评估研究的方法学质量。结果:在包括19,024,539例分娩的10项研究中,埃塞俄比亚CL/P的总出生患病率为每1,000例活产0.24例(95% CI: 0.12-0.36)。研究中观察到相当大的异质性(I² = 99.94%,τ² = 0.04,Q = 8546.85,p < 0.001),反映了患病率估计值的实质性差异。结论:尽管埃塞俄比亚的CL/P患病率低于全球平均水平,但它代表了一个重大的公共卫生问题。这强调需要加强预防措施,促进早期发现和扩大获得及时和全面治疗服务的机会,这对于减轻这些先天性异常的负担至关重要。

Key Clinical Message

Lacrimal sac squamous cell carcinoma is extremely rare, and treatment guidelines remain unclear. In select cases, wide en bloc resection combined with prosthetic rehabilitation may offer the best outcomes. This case report advocates a multidisciplinary, consensus-driven approach centered on patient outcomes, with the use of a 3D printed skull with the benefits of gaining insight and providing visualisation pre-operatively. In addition, we want to emphasise the importance of speed in diagnosis and treatment in this report, in order to ensure optimal care.

Summary

Lacrimal sac squamous cell carcinoma is a rare epithelial malignancy often misdiagnosed as chronic dacryocystitis, delaying treatment. This article reports a pT4bN2bM0 case in a 67-year-old man treated with wide en bloc resection, yielding clear margins (>6 mm) and found after 4 months from initial symptoms. A 3D-printed skull model aided preoperative visualization. Histology revealed lymphovascular invasion and broad nests of atypical squamous cells with dyskeratosis and necrosis, confirming lacrimal origin. Adjuvant chemoradiotherapy followed. At 21 months follow-up, no signs of local, regional, or distant recurrence were observed.
关键临床信息:泪囊鳞状细胞癌极为罕见,治疗指南尚不明确。在某些情况下,广泛的整体切除结合假肢康复可能会提供最好的结果。本病例报告倡导以患者结果为中心的多学科,共识驱动的方法,使用3D打印头骨,具有获得洞察力和术前可视化的好处。此外,我们要在本报告中强调诊断和治疗速度的重要性,以确保最佳护理。摘要:泪囊鳞状细胞癌是一种罕见的上皮恶性肿瘤,常被误诊为慢性泪囊炎,延误治疗。本文报道一例67岁男性pT4bN2bM0病例,行大面积全切除治疗,边缘清晰(bbb6mm),在症状消失4个月后发现。3d打印颅骨模型辅助术前可视化。组织学显示淋巴血管浸润和广泛的非典型鳞状细胞巢伴角化不良和坏死,证实泪源性。随后进行辅助放化疗。在8个月的随访中,没有观察到局部、区域或远处复发的迹象。

Introduction

Bruxism is a repetitive jaw-muscle activity, involving teeth clenching, grinding, and mandibular bracing or thrusting, occurring during wakefulness or sleep. Its multifactorial etiology includes neurophysiological, psychosocial, and pharmacological factors. Increasing evidence suggests an association between serotonergic antidepressants—especially SSRIs and SNRIs—and the onset or worsening of bruxism. This study aims to assess bruxism prevalence among SSRI/SNRI users and explore its correlation with demographic, occupational, and psychosocial factors.

Material and methods

A retrospective cross-sectional analysis was conducted based on clinical records of patients treated at the Temporomandibular Disorders Clinic of the Federal University of the Jequitinhonha and Mucuri Valleys (Brazil) between 2013 and 2024. Bruxism diagnosis was based on self-report and clinical evidence of tooth wear. Because the database spans years predating the publication of the STAB consensus, standardized STAB-based diagnostic protocols could not be retrospectively applied. Data were analyzed using Pearson’s chi-square and logistic regression (α = 0.05).

Results

Among 583 patients evaluated, 400 (68.6%) presented signs of bruxism. Fifty-three (9.1%) were SSRI/SNRI users, of whom 43 (81.1%) exhibited bruxism. Logistic regression revealed that antidepressant users were 2.5 times more likely to present bruxism than non-users (OR = 2.52; 95% CI: 1.21–5.23; p = 0.014). Occupational stress, particularly among students, was also significantly associated (OR = 1.77; p = 0.004). Axis II–related symptoms (stress, anxiety, and depression) showed no statistical significance.

Discussion

The use of serotonergic antidepressants, especially SSRIs, was significantly associated with bruxism. These findings underscore the importance of considering psychopharmacological and psychosocial factors in the diagnostic and therapeutic management of bruxism.
磨牙症是在清醒或睡眠时发生的一种重复性颚肌活动,包括咬牙、磨牙、下颌支撑或推牙。其多因素病因包括神经生理、社会心理和药理学因素。越来越多的证据表明,血清素类抗抑郁药——尤其是SSRIs和snris——与磨牙症的发病或恶化有关。本研究旨在评估磨牙症在SSRI/SNRI使用者中的患病率,并探讨其与人口统计学、职业和社会心理因素的相关性。材料和方法:回顾性横断面分析2013 - 2024年在巴西联邦大学XXXXXXXXXX颞下颌疾病诊所治疗的患者的临床记录。磨牙症的诊断是基于自我报告和牙齿磨损的临床证据。由于该数据库涵盖了STAB共识发表之前的数年,因此标准化的基于STAB的诊断方案无法回顾性应用。数据分析采用Pearson卡方和logistic回归(α = 0.05)。结果:583例患者中,400例(68.6%)出现磨牙症状。SSRI/SNRI使用者53例(9.1%),其中磨牙43例(81.1%)。Logistic回归显示,抗抑郁药服用者出现磨牙的可能性是非服用者的2.5倍(OR = 2.52;95% CI: 1.21-5.23; p = 0.014)。职业压力,尤其是学生,也显著相关(OR = 1.77;p = 0.004)。轴ii相关症状(压力、焦虑和抑郁)无统计学意义。讨论:5 -羟色胺类抗抑郁药的使用,尤其是SSRIs类抗抑郁药,与磨牙症显著相关。这些发现强调了在磨牙症的诊断和治疗管理中考虑精神药理学和社会心理因素的重要性。

Lip amputations in children may require urgent microsurgical management. Here we report a salvage procedure with partial survival following lower lip and chin replantation after a trampoline accident. Total amputation was managed with inferior labial artery anastomosis; however, venous drainage was not reestablished, necessitating leech therapy. Despite arterial revisions, 75 % of the lip and 25 % of the chin were lost by post-operative day 14. Reconstruction with a combined right Karapandzic flap and left Camille Bernard flap was performed one month later, supplemented by mesotherapy and nanofat injections. The outcome was marked by residual microstomia. These injuries are rare in children, often caused by dog bites. Venous anastomosis is frequently unfeasible, with leech therapy critical for drainage. When replantation is partially successful, reconstruction may involve local flaps or free tissue transfers. Microsurgical expertise, access to leech therapy and close collaboration with intensivists are essential for optimizing outcomes.
儿童唇部截肢可能需要紧急显微外科治疗。在此,我们报告一个在蹦床事故后下唇和下巴再植后部分存活的抢救手术。全截肢采用唇下动脉吻合术;然而,静脉引流没有恢复,需要水蛭治疗。尽管动脉修复,术后第14天75%的嘴唇和25%的下巴都消失了。1个月后行右侧Karapandzic皮瓣和左侧Camille Bernard皮瓣联合重建,并辅以化疗和纳米脂肪注射。结果以残留的小口畸形为标志。这些伤害在儿童中很少见,通常是由狗咬伤引起的。静脉吻合通常不可行,水蛭疗法对引流至关重要。当再植部分成功时,重建可能涉及局部皮瓣或游离组织转移。显微外科专业知识、获得水蛭疗法以及与重症医师密切合作对于优化结果至关重要。

Background

Mandibular defect reconstruction after tumor resection poses significant challenges in oral and maxillofacial surgery. The free fibula flap is widely used and effective for reconstructing such defects. Traditional manual segmentation and stabilization can lead to inaccuracies; while 3D-printed guides improve cutting precision, they often overlook the stabilization of bone segments. The conventional surgical template system consists of three separate guides: a tumor removal guide, a fibula cutting guide, and a reconstruction guide, which requires manual detachment and reshaping of fibula segments before reconstruction. In contrast, the spliced surgical template system integrates an additional fibula cutting frame and reconstruction frame. This allows the fibula cutting guides to transform directly into the reconstruction guide without detaching the segments, thereby simplifying the workflow and improving stabilization accuracy. This study evaluates a spliced surgical template system and compares its accuracy in stabilizing bone segments with that of conventional systems.

Patient and method

A retrospective cohort study was conducted for patients who underwent mandibular tumor resection and free fibula flap reconstruction at Shanghai Ninth People’s Hospital from 01/01/2022 to 31/03/2025. Patients were divided into two groups based on whether they used conventional or spliced surgical template systems. Preoperative virtual surgical planning was adapted to create 3D models, cutting guides, and reconstructing guides. Postoperative CT scans were also analyzed to assess reconstruction accuracy by measuring deviations in three dimensions.

Result

20 patients were included; 10 used the spliced surgical template system, and the rest used the conventional ones. The spliced system showed significantly more minor errors in reconstruction accuracy than the other. The offset was X-axis 0.31 [0.13, 0.97] mm, Y-axis 0.32 [0.11, 0.78] mm, and Z-axis 0.37 [0.06, 0.47] mm for the spliced system, versus 4.03 [0.61, 18.49] mm, 3.50 [0.66, 13.94] mm, and 3.14 [0.85, 7.25] mm for the conventional system, which were all statistically significant (p < 0.05).

Conclusion

The spliced surgical template system provides higher accuracy and stability in mandibular reconstruction with the free fibula flap. It reduces errors in the positioning of fibula segments, resulting in improved reconstruction precision and potentially contributing to better functional outcomes compared with conventional methods.
背景:下颌骨肿瘤切除后缺损重建是口腔颌面外科的一大挑战。游离腓骨瓣在腓骨缺损重建中应用广泛,效果良好。传统的人工分割和稳定会导致不准确;虽然3d打印导向器提高了切割精度,但它们往往忽略了骨段的稳定性。传统的手术模板系统由三个独立的导向器组成:肿瘤切除导向器、腓骨切割导向器和重建导向器,重建前需要手工剥离和重塑腓骨节段。相比之下,拼接手术模板系统集成了一个额外的腓骨切割框架和重建框架。这使得腓骨切割导轨可以直接转换为重建导轨,而无需分离节段,从而简化了工作流程并提高了稳定精度。本研究评估了拼接手术模板系统,并比较了其在稳定骨段的准确性与传统系统。患者与方法:对2022年1月1日至2025年3月31日在上海市第九人民医院行下颌骨肿瘤切除术及游离腓骨皮瓣重建术的患者进行回顾性队列研究。患者根据是否使用常规或拼接手术模板系统分为两组。术前虚拟手术计划适用于创建三维模型、切割导片和重建导片。术后CT扫描也通过测量三维偏差来评估重建的准确性。结果:纳入20例患者;10例采用拼接手术模板系统,其余采用常规手术模板系统。拼接系统在重建精度上的小误差明显大于其他拼接系统。与传统系统的4.03 [0.61,18.49]mm、3.50 [0.66,13.94]mm、3.14 [0.85,7.25]mm相比,拼接系统的x轴偏移量为0.31 [0.13,0.97]mm、y轴偏移量为0.32 [0.11,0.78]mm、z轴偏移量为0.37 [0.06,0.47]mm,差异均有统计学意义(p结论:拼接手术模板系统在游离腓骨瓣下颌骨重建中具有更高的准确性和稳定性。它减少了腓骨节段定位的错误,从而提高了重建精度,与传统方法相比,可能有助于更好的功能结果。

Background

Despite complete surgical resection, recurrence remains a substantial challenge in patients with early-stage oral squamous cell carcinoma (OSSC). Conventional TNM staging does not fully capture the biological heterogeneity underlying relapse. This study aimed to develop an individualized recurrence-prediction model integrating clinicopathologic, immune, and spatial factors, and to evaluate the potential mediating role of perineural invasion (PNI).

Methods

We retrospectively analyzed 451 patients with stage I–II OSCC treated at Xiangya Hospital between 2018 and 2025. Twenty-three clinical, pathological, and immunohistochemical variables were initially screened using LASSO regression. Independent predictors of recurrence were subsequently identified through multivariable Cox analysis. A nomogram was constructed based on the final Cox model and internally validated using Harrell’s C-index, time-dependent AUCs, and 1,000-bootstrap calibration. Risk stratification was performed using Kaplan–Meier curves, and mediation analysis was used to determine whether PNI mediated the effects of tumor grade, P53 status, and age on recurrence.

Results

Six independent predictors were incorporated into the final model: tumor grade, PNI, postoperative lymphocyte nadir, tumor-to-midline distance, pathological stage, and P53 status. The model demonstrated good discrimination (C-index = 0.79) and strong time-dependent predictive accuracy (AUCs: 0.819, 0.825, and 0.807 at 1, 3, and 5 years, respectively). Calibration curves showed excellent agreement between predicted and observed recurrence probabilities. Risk stratification based on the nomogram clearly separated patients into low- and high-risk groups (log-rank p < 0.001). Mediation analysis showed that PNI partially mediated the effects of tumor grade (proportion mediated = 29.6%) and P53 status (7.7%) on recurrence, whereas age exhibited no significant mediation through PNI.

Conclusions

This integrated prognostic model combines immune recovery, spatial invasion, and molecular features to accurately predict recurrence in early-stage OSCC. The partial mediation of tumor aggressiveness through PNI highlights a biological pathway linking tumor phenotype to recurrence risk. The proposed nomogram provides a clinically applicable tool for postoperative risk stratification and may assist in tailoring surveillance strategies and individualized adjuvant treatment decisions.
背景:尽管完全手术切除,早期口腔鳞状细胞癌(OSSC)患者的复发仍然是一个重大挑战。传统的TNM分期不能完全反映复发的生物学异质性。本研究旨在建立一个综合临床病理、免疫和空间因素的个体化复发预测模型,并评估围神经浸润(PNI)的潜在介导作用。方法:回顾性分析2018年至2025年在湘雅医院治疗的451例I-II期OSCC患者。最初使用LASSO回归筛选23个临床、病理和免疫组织化学变量。随后通过多变量Cox分析确定了复发的独立预测因素。基于最终Cox模型构建nomogram,并使用Harrell’s C-index、随时间变化的auc和1000 -bootstrap校准进行内部验证。采用Kaplan-Meier曲线进行风险分层,并采用中介分析确定PNI是否介导肿瘤分级、P53状态和年龄对复发的影响。结果:最终模型纳入了六个独立的预测因素:肿瘤分级、PNI、术后淋巴细胞最低点、肿瘤至中线距离、病理分期和P53状态。该模型具有良好的判别性(C-index = 0.79)和较强的时间依赖性预测精度(auc分别为0.819、0.825和0.807,分别为1、3和5年)。校正曲线在预测和观测的重复概率之间表现出良好的一致性。基于nomogram风险分层将患者明确分为低危组和高危组(log-rank p < 0.001)。中介分析显示PNI部分介导肿瘤分级(比例介导 = 29.6%)和P53状态(7.7%)对复发的影响,而年龄没有通过PNI发挥显著的中介作用。结论:该综合预后模型结合了免疫恢复、空间侵袭和分子特征,可准确预测早期OSCC的复发。通过PNI部分介导肿瘤侵袭性强调了将肿瘤表型与复发风险联系起来的生物学途径。所提出的nomogram为术后风险分层提供了一种临床应用的工具,并可能有助于定制监测策略和个性化的辅助治疗决策。

Background

Accurate biomechanical characterization of asymptomatic TMJ function requires anatomically complete, subject-specific models, yet such validated finite element (FE) frameworks remain limited.

Objective

To introduce and technically evaluate a novel MRI-validated, kinematically -driven, anatomically complete, subject-specific 3D nonlinear FE TMJ framework, and to demonstrate its biomechanical responses in one asymptomatic subject and two Class II cases with mild and moderate anterior disc displacement during the four-finger mouth-opening test.

Methods

Three subject-specific TMJ models were constructed using CBCT for hard tissues and high-resolution MRI for soft tissues. A hybrid anatomical workflow integrating 3D Slicer, Blender, and ANSYS SpaceClaim enabled complete maxillofacial reconstruction. Nonlinear FE simulations (ANSYS Workbench) quantified stresses in the disc, condylar head, condylar neck, articular eminence, and glenoid fossa using validated material properties, frictional contacts, and physiological kinematic loading derived from motion-capture trajectories.

Results

MRI-based geometric and kinematic validation showed <5% error in disc rotational angle and condylar translation. In the asymptomatic subject, compressive stresses occurred in intermediate disc regions, with tensile stresses near anterior and posterior attachments. The mild displacement case showed elevated posterior disc and anterior condylar stresses, while the moderate case exhibited the highest disc, condylar head, and neck stresses 0.637 MPa and 1.40 MPa, respectively. Across all three individuals, maximum stresses occurred as the condyle advanced over the articular eminence.

Conclusion

This feasibility study introduces a validated, anatomically complete subject-specific FE TMJ model that captures rotation–translation in the asymptomatic case and restricted translation with elevated stresses in mild and moderate displacement, supporting future expansion.
背景:准确的无症状TMJ功能的生物力学特征需要解剖学完整的、特定于受试者的模型,然而这种有效的有限元(FE)框架仍然有限。目的:介绍并技术评价一种新的mri验证的、运动学驱动的、解剖完整的、受试者特异性的三维非线性FE TMJ框架,并在四指开口试验中展示其在一名无症状受试者和两名轻度和中度前椎间盘移位的II类患者中的生物力学反应。方法:采用CBCT(硬组织)和高分辨率MRI(软组织)构建3个受试者特异性TMJ模型。混合解剖工作流程集成了3D切片器,搅拌机和ANSYS spacecclaim,实现了完整的颌面重建。非线性有限元模拟(ANSYS Workbench)利用经过验证的材料特性、摩擦接触和源自运动捕捉轨迹的生理运动学载荷,量化了椎间盘、髁突头、髁突颈、关节隆起和关节窝的应力。结论:这项可行性研究引入了一个经过验证的、解剖完整的受试者特异性FE TMJ模型,该模型可以捕获无症状病例的旋转平移和轻度和中度位移时应力升高的受限平移,为未来的扩展提供支持。

Background

Preserving an adequate residual mandibular height during marginal mandibulectomy is essential to reduce the risk of postoperative fracture while maintaining oncologic safety in patients with oral squamous cell carcinoma (OSCC).

Purpose

The aim of this study was to evaluate the oncologic outcomes of marginal mandibulectomy guided by the mental foramen and to assess its relevance as an anatomical landmark for osteotomy.

Material and methods

Patients treated for OSCC by marginal mandibulectomy with localization of the mental foramen between 2007 and 2022 were retrospectively included. The primary endpoint was bone resection margin status. Secondary endpoints included local recurrence-free survival, disease-free survival, and overall survival. An anatomical analysis of the mental foramen position relative to the inferior osteotomy line was performed using postoperative computed tomography.

Results

A total of 150 patients met all inclusion criteria. Clear bone margins (R0) were achieved in 98 % of cases. Bone invasion (pT4) was observed in 41.3 % of patients. At 5 years, local recurrence-free survival, disease-free survival, and overall survival were consistent with outcomes reported for selected OSCC treated by marginal mandibulectomy. No immediate postoperative mandibular fractures were observed. The inferior osteotomy line showed a consistent relationship with the mental foramen.

Conclusion

Marginal mandibulectomy guided by the mental foramen allows reproducible bone resection while achieving satisfactory oncologic outcomes. The mental foramen constitutes a reliable anatomical landmark for osteotomy in carefully selected patients with OSCC.
背景:对于口腔鳞状细胞癌(OSCC)患者,在下颌边缘切除术中保留足够的下颌高度对于降低术后骨折风险和维持肿瘤安全至关重要。目的:本研究的目的是评估颏孔引导下颌骨边缘切除术的肿瘤学结果,并评估其作为截骨术的解剖学标志的相关性。材料和方法:回顾性分析2007年至2022年间接受下颌边缘切除术并颏孔定位治疗OSCC的患者。主要终点是骨切除边缘状态。次要终点包括局部无复发生存期、无病生存期和总生存期。使用术后计算机断层扫描对相对于下截骨线的颏孔位置进行解剖分析。结果:共有150例患者符合所有纳入标准。98%的病例骨缘清晰(R0)。41.3%的患者出现骨侵犯(pT4)。5年时,局部无复发生存期、无疾病生存期和总生存期与经下颌边缘切除术治疗的选择性OSCC报告的结果一致。术后未见下颌骨骨折。下截骨线与颏孔的关系一致。结论:颏孔引导下的下颌骨边缘切除术可获得满意的肿瘤治疗效果。在精心挑选的OSCC患者中,颏孔构成了可靠的截骨解剖学标志。

Temporomandibular joint discopexy techniques performed by arthroscopy have undergone multiple modifications to reduce the learning curve. Multiple modifications have been made to the technique and instruments; however, discopexy remains challenging due to the difficulty in suture capture. The curved technique leaves the suture in a more comfortable position for capturing the suture with the forceps in a simple way, facilitating the procedure and reducing surgical times without the need for special equipment.
通过关节镜进行的颞下颌关节脱位术已经经过了多次修改,以减少学习曲线。对技术和仪器进行了多次修改;然而,由于缝线捕获困难,discopix仍然具有挑战性。弯曲技术使缝线处于更舒适的位置,便于钳钳简单地捕捉缝线,方便手术,减少手术时间,无需特殊设备。
