Microvascular decompression (MVD) plays a pivotal role in the treatment of cranial neurovascular compression syndromes, yet the safety and precision of the surgery remain a focus of clinical attention. This article delves into the application of multimodal reconstruction and 3D printing technologies in MVD surgeries, evaluating their effectiveness in preoperative planning. Multimodal reconstruction, by integrating various imaging techniques such as magnetic resonance imaging (MRI) and computed tomography (CT), provides high-resolution anatomical information, offering comprehensive data support for preoperative planning and intraoperative navigation. Complementing this, 3D printing technology presents patients' anatomical structures as individualized physical models, enabling surgeons to fabricate corresponding skin templates for surgical needs, offering intuitive and practical references. Case studies presented in this article demonstrate the application and efficacy of these technologies in actual MVD surgeries. The results suggest that multimodal reconstruction and 3D printing technologies aid surgical teams in better understanding patients' anatomical structures during preoperative planning, enhancing surgical accuracy, reducing operative time, and shortening hospital stays. Despite notable advancements in MVD surgeries, challenges such as data accuracy, technological complexity, and cost persist. Future research should aim to address these issues, further optimizing the technologies and promoting their widespread application in neurosurgical procedures. Through in-depth investigation and understanding of these advanced technologies, we hope to pave new paths for improving surgical outcomes and patients' quality of life.
微血管减压术（MVD）在治疗颅内神经血管压迫综合征中起着举足轻重的作用，但手术的安全性和精确性仍是临床关注的焦点。本文深入探讨了多模态重建和 3D 打印技术在 MVD 手术中的应用，评估了它们在术前规划中的有效性。多模态重建通过整合各种成像技术，如磁共振成像（MRI）和计算机断层扫描（CT），提供高分辨率的解剖信息，为术前规划和术中导航提供全面的数据支持。作为补充，3D 打印技术将患者的解剖结构以个性化物理模型的形式呈现出来，使外科医生能够根据手术需要制作相应的皮肤模板，提供直观而实用的参考。本文介绍的案例研究展示了这些技术在实际颅内压增高手术中的应用和功效。研究结果表明，多模态重建和三维打印技术有助于手术团队在术前规划时更好地了解患者的解剖结构，提高手术准确性，缩短手术时间，缩短住院时间。尽管 MVD 手术取得了显著进展，但数据准确性、技术复杂性和成本等挑战依然存在。未来的研究应致力于解决这些问题，进一步优化技术，促进其在神经外科手术中的广泛应用。我们希望通过对这些先进技术的深入研究和了解，为提高手术效果和患者生活质量铺平新的道路。

Porous polyethylene has been widely used in craniofacial reconstruction due to its biomechanical properties and ease of handling. The objective of this study was to perform a systematic review of the literature to summarize outcomes utilizing high-density porous polyethylene (HDPP) implants in cranioplasty. A literature search of PubMed, Cochrane Library, and Scopus databases was conducted to identify original studies with HDPP cranioplasty from inception to March 2023. Non-English articles, commentaries, absent indications or outcomes, and nonclinical studies were excluded. Data on patient demographics, indications, defect size and location, outcomes, and patient satisfaction were extracted. Summary statistics were calculated using weighted averages based on the available reported data. A total of 1089 patients involving 1104 cranioplasty procedures with HDPP were identified. Patients' mean age was 44.0 years (range 2 to 83 y). The mean follow-up duration was 32.0 months (range 2 wk to 8 y). Two studies comprising 17 patients (1.6%) included only pediatric patients. Alloplastic cranioplasty was required after treatment of cerebrovascular diseases (50.9%), tumor excision (32.0%), trauma (11.4%), trigeminal neuralgia/epilepsy (3.4%), and others such as abscesses/cysts (1.4%). The size of the defect ranged from 3 to 340 cm2. An overall postoperative complication rate of 2.3% was identified, especially in patients who had previously undergone surgery at the same site. When data were available, contour improvement and high patient satisfaction were reported in 98.8% and 98.3% of the patients. HDPP implants exhibit favorable outcomes for reconstruction of skull defects. Higher complication rates may be anticipated in secondary cranioplasty cases.

The aim of this study is to ascertain how women of that era looked to a Korean diplomat who visited Japan in the 18th century. During 1763-1764, the "Documents on Joseon Tongsinsa (diplomatic mission)" contain 10 records of Korea and 2 records of Japan. Among them, "The Song of a Grand Trip to Japan" (), a Joseon gasa, was reviewed. In the diary entries dated February 2 and 3, 1764, when he was in Nagoya, the author (Kim Ingyeom) described the physical appearance of Japanese women in the city. The peoples of here are bright and beautiful/ All the women are peerless beauties. With eyes like stars and cinnabar-red lips / A clear complexion like white jade, eyebrows like butterflies,/ Hands like budding sprouts, forehead like a cicada. They look like carved ice and as if lumped together with snow. How are they so beautiful despite having the flesh and blood of a human being? Though Zhao Feiyan and Yang Guifei (queens of China) are called the eternal beauties,/ They would look less beautiful compared to women here. If they dressed in Korean costumes and were decorated with jewels,/ We would forget ourselves and mistaken them as goddesses. He highlighted features such as prominent foreheads, eyebrows shaped like butterflies, star-like eyes, red lips, slender hands, and pale skin. He portrayed Japanese women as having a superior appearance compared to Chinese or Korean women. This record suggests that a diplomat admired the appearance of Japanese women during the Meiwa Era (1764-1772).

The aim of this study was to determine how the aging-related changes of a beautiful woman were described in Japanese literature. A poem written by Ono no Komachi was reviewed. Images of her were also searched through Google search. Komachi's poem in Hyakunin Isshu reads: "How the color has faded from the flowers. As I gaze in reverie at the falling rain, I find my beauty, too, has fallen in this world's esteem." Tamatsukuri Komachiko's Death Book describes: "She became thin and looked tired. Her hair looks like a lotus with frost. Her skin resembles a frozen pear. Her bones stick out and her tendons are visible. Her face is dark, and her teeth are yellow". Color woodblock print shows an old woman: She retains her intelligence and beauty even in her advanced years. Her posture was stooped, with a pronounced forward curvature of the spine, resulting as "turtle neck." Her hair was long and gray. Visible signs of aging included forehead wrinkles, crow's feet, deepened nasolabial folds, and marionette lines. Her upper jaw appeared retracted, a "witch's chin." She exhibited neck wrinkles as well as on her hands and wrists, which grasped a bamboo walking stick. Her eyes were sunken, accompanied by a drooping of the upper eyelids. We think that the narrative of her transformation into an ugly and poor woman was intended to convey to men the fleeting nature of women's beauty, and to women that the power of beauty is not ultimately of major significance.

The natural history of spinal cord cavernous malformation (SCM) may be characterized by recurrent episodes of hemorrhage resulting in a range of neurologic deficits, most of which are microhemorrhage and subsequent gliosis that can lead to progressive myelopathy. Macrohemorrhage with acute onset of symptoms is extremely rare and leads to irreversible neurologic deficits. In this article, we present an unusual case of ruptured cavernous malformation (CM) in the cervical spinal cord with large extralesional hemorrhage. The patient underwent an operation of posterior longitudinal myelotomy and had a good neurologic recovery. A histologic examination revealed the typical features of cavernous angioma.

Involutional blepharoptosis is common among elderly people. The tightening of eyelids postptosis surgery could potentially increase friction between the eyelid and the ocular surface, but this hypothesis has not yet been substantiated by research. The authors explored the relationship between involutional blepharoptosis surgery and friction-related diseases, namely conjunctivochalasis, lid wiper epitheliopathy, and superior limbic keratoconjunctivitis.

The purpose of the present study was to investigate the pharyngeal airway space (PAS) changes in class III patients receiving bimaxillary orthognathic surgery and correlate the PAS volume and minimum axial section changes with the magnitude of the surgical movement. This research involved a retrospective sample composed of 38 patients with class III skeletal occlusions. Three-dimensional measurements of the PAS volume and minimum axial section were conducted. Cephalometric points were used to verify the extent of jaw-hyoid bone movement. No significant differences were found between pre and postoperative total PAS volume (P = 0.280), nasopharyngeal volume (P = 0.545), oropharyngeal volume (P = 0.297), and minimum axial section (P = 0.568). Anterior movement of point A and posterior nasal spine were significantly associated with an increase in total PAS volume, oropharyngeal volume, and minimum axial section (P < 0.05). However, the posterior movement of menton was significantly associated with a decrease in total PAS volume, oropharyngeal volume, and minimum axial section (P < 0.05). The results of the present study indicated that PAS is not negatively affected by bimaxillary surgery in class III patients. However, the planning of class III patients who are prone to the development of airway problems should be done carefully.
本研究的目的是调查接受双颌正颌手术的 III 类患者咽部气道空间（PAS）的变化，并将 PAS 体积和最小轴切面的变化与手术移动的幅度相关联。这项研究采用了回顾性样本，包括 38 名 III 级骨骼闭塞患者。对 PAS 体积和最小轴切面进行了三维测量。头颅测量点用于验证下颌-舌骨移动的程度。术前和术后的 PAS 总体积（P = 0.280）、鼻咽部体积（P = 0.545）、口咽部体积（P = 0.297）和最小轴切面（P = 0.568）均无明显差异。A 点和鼻后脊柱的前移与 PAS 总容积、口咽容积和最小轴截面的增加显著相关（P < 0.05）。然而，门顿后移与 PAS 总容积、口咽容积和最小轴切面的减少明显相关（P < 0.05）。本研究结果表明，双颌手术不会对 III 类患者的 PAS 产生负面影响。但是，对于容易出现气道问题的 III 类患者，应谨慎制定计划。

The purpose of this study was to assess the effects of protecting the facial nerve with a modified endaural approach with a peripheral dissection of the superficial musculoaponeurotic system to access the temporomandibular joint which allows an excellent operative field of visualization, multiple surgical procedures of the temporomandibular joint, and general care which improves the immediate postoperative period, making this a less morbid surgery. This study included 33 patients (39 sides) who underwent surgical treatment for disorders of the temporomandibular joint from the years 2021 to 2023 at the maxillofacial department of the clinic "Colsanitas" located in Bogota, Colombia. Therapeutic results were evaluated by postoperative facial nerve injury, with the House-Brackman scale; every patient was examined for adequate facial musculature function immediately after surgery. Notably, zero patients presented facial nerve injury. These results imply that the modified endaural approach with a peripheral dissection of the superficial musculoaponeurotic system to access the temporomandibular joint reduces the incidence of facial nerve injuries, improves operative site exposure, and lowers the frequency of complications.

These results imply that the modified endaural approach with a peripheral dissection of the superficial musculoaponeurotic system to access the temporomandibular joint reduces the incidence of facial nerve injuries, improves operative site exposure, and lowers the frequency of complications.","PeriodicalId":501649,"journal":{"name":"The Journal of Craniofacial Surgery","volume":"45 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140828637","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dog-ear deformity is a common protrusion defect of skin tissue after the closure of a surgical wound, affecting patients' appearance and quality of life. The common methods for correcting dog ears involve the removal of excess tissue in different directions or shapes after extending the incision along the long axis of the original wound. However, the literature regarding tissue preservation techniques for dog-ear correction is poor, especially for areas with insufficient skin tissue or high tension. The authors modified the original design of direct excisions, which transferred excess tissue from the horizontal axis of the wound to the longitudinal axis, thereby absorbing longitudinal tension and relieving linear scar contracture. This technique provides a way to correct dog ears without removing excess healthy tissue, especially as an option for dog-ear correction in high-tension areas.
