Introduction
The current imaging report describes a unique coexistence of the neck venous system morphological variants.
Methods
The imaging study of a 75-year-old male patient was isolated due to its unique venous system.
Results
An internal jugular vein (IJV) duplication (main-typical and accessory IJVs) was identified on the right side, coexisting with a facial vein (FV) drainage into the accessory IJV. On the left side, the external jugular vein (EJV) was draining into the IJV and the FV into the EJV. A transverse anastomosis of the EJV and anterior jugular vein (AJV) was identified.
Conclusions
The IJV duplication is a rare morphological variant, and its coexistence with other co-variants complicates the area's anatomy. Understanding these morphological variants is crucial for anesthesiologists and surgeons, as it can help prevent iatrogenic injury.

Background
Digital 3D visualisation tools have been increasingly used to supplement anatomy teaching with positive results reported in knowledge acquisition, 3D spatial understanding, and active student engagement. Despite their well-documented benefits, evidence of their learning effect on head and neck anatomy is limited.
Methods
This cross-over design study aimed to compare using Complete Anatomy (CA) and conventional methods (prosections and plastic models) to learn laryngeal anatomy. Fifty-four first-year dental and dental hygiene students were randomly assigned to a CA and a conventional group. Pre- and post-tests were used to compare groups' knowledge gains, and a feedback questionnaire was used to compare students' perceptions towards CA.
Results
Both groups improved significantly in the post-test compared to the pre-test (Cohen's d ≥ 0.8). The conventional group significantly outperformed their counterparts in total (Cohen's d = 0.57) and written questions (Cohen's d = 0.9). However, both groups performed equally in the identification questions. Question-based analysis shows that the CA group performed significantly better in the identification questions than in the written questions (Cohen's d = 0.51). Nearly half the students perceived the CA application as easy to use, and the same proportion believed CA assisted their learning of laryngeal anatomy.
Conclusion
This study provides further evidence of the effectiveness of CA in knowledge gain and anatomical recognition and supports its use as supplementary to anatomy education in general and head and neck anatomy in particular.
背景数字三维可视化工具已越来越多地用于辅助解剖学教学，据报道在知识获取、三维空间理解和学生积极参与方面取得了积极成果。本交叉设计研究旨在比较使用完整解剖学（CA）和传统方法（剖面图和塑料模型）来学习喉部解剖。54名一年级牙科和口腔卫生专业的学生被随机分配到CA组和传统组。结果两组学生的后测成绩均比前测有显著提高（Cohen's d ≥ 0.8）。传统组在总成绩（Cohen's d = 0.57）和书面问题（Cohen's d = 0.9）方面明显优于传统组。然而，两组在识别问题上的表现相当。基于问题的分析表明，CA 组在识别问题上的表现明显优于书面问题（Cohen's d = 0.51）。近一半的学生认为 CA 应用程序易于使用，相同比例的学生认为 CA 有助于他们学习喉部解剖学。

Introduction
The tensor fasciae suralis (TFS) is a non-typical skeletal muscle that develops from one of the hamstring muscles and attaches to the deep fascia of the posterior leg (i.e., crural/sural fascia). By spanning the popliteal region, TFS can present as an unsuspected mass, impinge contiguous neurovasculature, complicate surgical access to posterior knee, and strain under typical use of the lower limb. Despite the necessary clinical discussion TFS generates, information about comparative gross anatomy examination, magnetic resonance imaging (MRI), and functional analyses of TFS is scarce in the literature. Therefore, the objective of the present study is to present a comprehensive report of a left unilateral TFS with gross imaging, detailed anatomical descriptions, MRI, biomechanical analysis, comparative review of published TFS cases, and discussion of clinical implications.
Methods
A left unilateral TFS was discovered during routine human cadaver dissection. After initial discovery of its proximal segment, axial and sagittal T1-and T2-weighted MRI was performed to visualize the entire TFS and its relation to nearby structures. The entire TFS and contiguous anatomy were then dissected, carefully cleaned of extraneous fascia, and photographed in situ. Gross and microscopic architectural features of TFS were measured, and its maximal isometric force was calculated.
Results
The 13.4 cm long, 5.02 g muscular belly of TFS branched 27.2° from the long head of biceps femoris and inserted into the investing fascia of the gastrocnemius medial head via a prominent 2.6 cm × 4.8 mm x 0.5 mm tendon. Gross imaging and MRI showed TFS crossing over the common fibular, tibial, and medial sural nerves. Biomechanical analysis determined TFS to be capable of producing 8.10 N of force.
Conclusions
The course of TFS offers notable clinical discussion about distal motor and sensory loss resulting from compression-based lesions of the underlying nerves. MRI, paired with full gross imaging and biomechanical analyses, provides a catalog of comparative information on TFS that may aide in differential diagnosis of an unsuspected mass in the popliteal region and guide subsequent treatment.

Introduction
Recent studies showed the connection between cerebrospinal fluid (CSF) and deep cervical lymph nodes (dCLN) via lymphatic vessels (LV)s. These LVs accompany dural sinuses, cranial nerves, and arteries. The present study aimed to show in addition to the main trunk of the middle meningeal artery (MMA) whether the anterior and posterior branches of MMA; the anterior (AMA) and posterior (PMA) meningeal arteries also have a role in brain lymphatic drainage in humans.
Materials and method
Samples of the middle meningeal artery (MMA) and its two main branches (anterior and posterior), anterior and posterior meningeal arteries (AMA and PMA) were obtained from 3 cadavers and 6 autopsies. Podoplanin (PDPN) (lymphatic endothelial marker) and CD31 (vascular endothelial marker) immunohistochemistry (IHC) were applied to 5 μm thick transverse sections and counterstained with hematoxylin. Furthermore, western blotting techniques were applied to the same tissue samples in 3 autopsy cases to demonstrate the presence of PDPN.
Results
We observed the presence of the LVs along the main trunk of MMA and its two branches, AMA, and PMA. The LVs along the MMA (main trunk) had a larger diameter range than its branches and the AMA and PMA. The diameter of LVs of the PMA was larger than AMA. Furthermore, fluid channels with varying diameters and densities were closely localized to the LVs. The western blot PDPN protein expression confirmed IHC results.
Conclusion
The LVs along the main trunk, anterior and posterior branches of the MMA, AMA, and PMA also provide an extracranial pathway for thought drainage of waste from the brain tissue in humans. Thus, the organization of the extracranial transport of LVs of the brain should be well-defined for understanding the role of lymphatic drainage in various neurological diseases.

Background
It usually takes many years for new techniques to translate into medical practice. While this can be due to several reasons, it often results in significant delays in medical advancement. For instance, shifts in societal and cultural norms can lead to different techniques or procedures being ‘lost’ to the field when certain practices are prohibited. It sometimes takes years for initiatives to reemerge, and dutiful research to recognize the true historical origins. In skin grafting, one such example is that of Dr. Otto Lanz’s Hautschlitzapparat invention, the instrument considered to be the prototype of the device now used to create skin mesh grafts. This paper aims to provide a brief overview of the history of skin grafting with a focus on how Lanz’s theory and device for what is now known as a meshed skin graft did not become mainstream practice until decades later.
Methods
A literature search in PubMed and Google Scholar on the history of skin grafting and the contribution of Dr. Otto Lanz to this field was conducted. The keywords used in the search criteria were “skin grafting” and “Otto Lanz”. The results were summarized into a narrative discussion, along with a brief biography of Dr. Otto Lanz.
Results
The prototype for the skin grafting device is credited to Dr. Otto Lanz who invented the Hautschlitzapparat (Skin Slit Apparatus) in 1907. This device was similar to the scarificator apparatus that existed since at least the 16th century. However, Lanz was the first to propose its use for expanding skin grafts, and instruments thereafter were based on the principle laid out by Otto Lanz. It took almost three decades for Lanz’s insight to fully translate to methods of skin grafting procedures utilizing mesh grafts.
Conclusion
Dr. Otto Lanz can be viewed as one of the pioneers of skin grafting as his invention laid a foundation for what is now known to be the skin mesher. The mesher has revolutionized skin grafting procedures by reducing the required size of donor skin grafts as well as the time for healing. The time delay between Dr. Lanz’s invention and the mainstream use of meshers demonstrates, once again, the time it usually takes for the translation of innovative ideas into practice.
背景新技术转化为医疗实践通常需要多年时间。这可能有多种原因，但往往会导致医学发展的重大延误。例如，当某些做法被禁止时，社会和文化规范的变化会导致不同的技术或程序 "消失"。有时需要数年时间才能重新出现相关举措，并通过尽职尽责的研究才能认识到其真正的历史渊源。在皮肤移植方面，奥托-兰兹博士发明的 Hautschlitzapparat 就是这样一个例子，该器械被认为是目前用于制作皮肤网状移植的设备的原型。本文旨在简要概述植皮术的历史，重点介绍 Lanz 的理论和现在被称为网状植皮的设备是如何在几十年后才成为主流实践的。方法在 PubMed 和 Google Scholar 上进行文献检索，内容涉及植皮术的历史和 Otto Lanz 博士在这一领域的贡献。搜索标准中使用的关键词是 "植皮 "和 "奥托-兰兹"。结果皮肤移植装置的原型归功于奥托-兰兹博士，他于 1907 年发明了 Hautschlitzapparat（皮肤切口装置）。该装置与至少在 16 世纪就已存在的刀疤器相似。不过，Lanz 是第一个提出将其用于扩大皮肤移植的人，此后的器械都是基于 Otto Lanz 提出的原理。奥托-兰兹博士可被视为皮肤移植的先驱之一，因为他的发明为现在众所周知的皮肤网格器奠定了基础。网格器彻底改变了植皮手术，减少了供体皮肤移植所需的面积，缩短了愈合时间。从 Lanz 博士的发明到网格器的主流使用之间的时间差再次表明，创新理念转化为实践通常需要一定的时间。

Aim
This study aims to explore the intramuscular innervation patterns of rectus extraocular muscles (REOMs) comprehensively. By supplementing existing knowledge using histological techniques to enrich current research findings, we endeavor to provide a holistic perspective on the complexities of REOM innervation.
Material and methods
Ten REOMs (superior, inferior, medial, and lateral) were collected from adult human cadavers of both sexes. All samples were carefully dissected to preserve muscle integrity and architecture and proceeded using H&E staining.
Results
Within each REOM, the intramuscular innervation is characterized by a dense network of motor sub-branches. Muscular sub-branches are distributed evenly within each REOM's mid-length cross-section.
Conclusions
In conclusion, the intramuscular innervation of the rectus extraocular muscles is a highly complex and organized system crucial for precisely controlling eyeball movements.

Chronic low back pain (CBP) is a heterogeneous disease that may be caused by intervertebral disc lesions, age-related degenerative lumbar vertebral bodies, nerve compressions at its exit points, age-related weakness of paraspinal muscles, or tendinous and myofascial causes. This study compared the changes in the cross-sectional area (CSA) of the paraspinal muscles between healthy individuals and patients with CBP at the L4 superior endplate level.
Methods
Magnetic Resonance (MR) Images of 50 healthy males without a history of back pain and 50 patients with CBP aged 40–60 years were retrospectively evaluated. The CSAs of the bilateral paraspinal muscles viz multifidus, erector spinae, psoas major, and quadratus lumborum were measured in the axial view at the level of the L4 superior endplate. The sagittal view of the MRI images at the L4 superior endplate level was selected to evaluate intervertebral disc (IVD) abnormalities. Further, these images were subjected to the Tissue Quant algorithm to quantify muscle atrophy and fat deposition.
Results
Sagittal section images showed diffuse bulges in the IVD of 28 patients with CBP rather than IVD extrusion or protrusion. Decreased multifidus CSA and a marginal increase in CSA of other paraspinal muscles were observed in CBP patients along with significant fat infiltration within the paraspinal muscles.
Conclusion
This study demonstrated a bilateral decrease in the CSA of multifidus muscles in patients with CBP compared with healthy individuals. In contrast, a slight increase in CSA was noted in the remaining paraspinal muscles, which may be due to reduced muscle mass and increased interfascicular fatty infiltration. Evaluating the manifestations of each paraspinal muscle and subsequent strengthening of the concerned muscle should be targeted for treating CBP.

This study compared the changes in the cross-sectional area (CSA) of the paraspinal muscles between healthy individuals and patients with CBP at the L4 superior endplate level.</p></div><div><h3>Methods</h3><p>Magnetic Resonance <strong>(</strong>MR) Images of 50 healthy males without a history of back pain and 50 patients with CBP aged 40–60 years were retrospectively evaluated. The CSAs of the bilateral paraspinal muscles viz multifidus, erector spinae, psoas major, and quadratus lumborum were measured in the axial view at the level of the L4 superior endplate. The sagittal view of the MRI images at the L4 superior endplate level was selected to evaluate intervertebral disc (IVD) abnormalities. Further, these images were subjected to the Tissue Quant algorithm to quantify muscle atrophy and fat deposition.</p></div><div><h3>Results</h3><p>Sagittal section images showed diffuse bulges in the IVD of 28 patients with CBP rather than IVD extrusion or protrusion. Decreased multifidus CSA and a marginal increase in CSA of other paraspinal muscles were observed in CBP patients along with significant fat infiltration within the paraspinal muscles.</p></div><div><h3>Conclusion</h3><p>This study demonstrated a bilateral decrease in the CSA of multifidus muscles in patients with CBP compared with healthy individuals.
