  • 文章类型: Journal Article
    背景:整容或除皱术是与年轻化最直接相关的手术。有几种整容手术技术,但是选择技术的标准,根据病人的面部形状,缺乏。在这项研究中,我们报告了我们对每种技术的特定适应症标准的经验,以及随之而来的良好结局。
    方法:从2015年到2023年,1名外科医生对1000名患者进行了整容。三种不同的浅表肌腱膜系统(SMAS)技术(SMAS解剖,SMA切除术,和SMAS折叠)根据患者下面部的下垂程度进行应用,侧面面部轮廓,和SMAS流动性和条件。考虑了浅表肌腱膜系统解剖以改善方形面部,下垂的下颚,和木偶线。浅表肌筋膜系统折叠术适用于下颌骨下垂较少,zygoma突出,面部侧面凹陷的患者。SMASecometory适用于外凸面部轮廓或SMAS太薄或受损的患者。术后1年使用FACE-Q评分调查患者术后满意度。
    结果:大多数患者获得了自然和持久的美学结果,并表现出很高的满意度。患者表示,手术后他们看起来比实际年龄年轻11.2±5.2岁。每个面部特征的平均满意度得分如下:脸颊(91.1±7.8),木偶线(88.5±13.6),下表面和下颚线(92.5±14.2),下巴下(87.8±15.1),和颈部(86.2±18.5)。并发症如面神经损伤,感染,血肿,皮瓣坏死非常罕见。
    结论:根据下面部下垂的程度,建立选择整容手术技术的标准,侧面面部轮廓,和SMAS流动性和条件导致了良好的结果。医生可以使用这些标准来根据患者的个体特征确定最有效的整容手术技术,这可能会改善手术结果。
    BACKGROUND: A face-lift or rhytidectomy is the procedure most directly associated with rejuvenation. There are several surgical techniques for face-lifts, but criteria for the selection of techniques, based on the patient\'s face shape, are lacking. In this study, we report on our experience with specific indication criteria for each technique and the consequent achievement of good outcomes.
    METHODS: From 2015 to 2023, 1 surgeon performed face-lifts on 1000 patients. Three different superficial musculoaponeurotic system (SMAS) techniques (SMAS dissection, SMASectomy, and SMAS plication) were applied depending on the degree of sagging of the patient\'s lower face, lateral facial profile, and SMAS mobility and condition. Superficial musculoaponeurotic system dissection was considered for the improvement of a square face, sagging jowls, and marionette lines. Superficial musculoaponeurotic system plication was applied with patients with less sagging jowls and prominent zygoma with concave lateral facial profile. SMASectomy was applied with patients with convex lateral facial profiles or when the SMAS was too thin or damaged. Patient postoperative satisfaction was surveyed using the FACE-Q score 1 year post surgery.
    RESULTS: Most of the patients attained natural-looking and long-lasting aesthetic outcomes and exhibited high satisfaction. The patients indicated that they looked about 11.2 ± 5.2 years younger than their actual age after the surgery. The mean satisfaction scores for each facial feature were as follows: cheeks (91.1 ± 7.8), marionette lines (88.5 ± 13.6), lower face and jawline (92.5 ± 14.2), under chin (87.8 ± 15.1), and neck (86.2 ± 18.5). Complications such as facial nerve injury, infection, hematoma, and flap necrosis were very rare.
    CONCLUSIONS: Establishing criteria for the selection of face-lift surgical techniques based on the degree of lower face sagging, lateral facial profile, and SMAS mobility and condition led to good outcomes. These criteria can be used by physicians to determine the most effective face-lift surgery technique based on a patient\'s individual features, which may improve surgical outcomes.

    背景:尽管它在鸭嘴肌和下唇的功能中起着重要作用,与其他分支相比,面神经的颈支经常被忽视,对于确保颈部手术的安全至关重要的考虑。
    目的:我们旨在阐明与面神经颈支相关的解剖学差异,以提高手术安全性。
    方法:该研究使用了20个新鲜冷冻的半头。采用了两阶段的外科手术,从最初的深平面整容开始,包括广泛的颈部解剖,然后对新鲜的冷冻尸体进行浅表腮腺切除术。这种方法可以对颈神经与其周围解剖结构的关系进行彻底的探索和定位。
    结果:离开腮腺后,颈神经始终在深颈筋膜的投资层下移动了一段短暂的距离,穿过深筋膜在乳晕结缔组织内行进,然后在颈阔肌向前终止。在两种情况下观察到单个分支,在18例病例中发现了两个分支。
    结论:颈神经在下颌骨角度以下的相对较深的位置有助于通过侧入路更安全的颈下夹层,以释放颈保留韧带。由于没有保护屏障,神经更容易受到直接创伤或电灼伤引起的热损伤,尤其是在中位数接近期间。
    BACKGROUND: Despite the significant roles it plays in the functions of the platysma and lower lip, the cervical branch of the facial nerve is often overlooked compared to other branches, but its consideration is critical for ensuring the safety of neck surgeries.
    OBJECTIVE: The aim of this study was to clarify the anatomical discrepancies associated with the cervical branch of the facial nerve to enhance surgical safety.
    METHODS: The study utilized 20 fresh-frozen hemiheads. A 2-stage surgical procedure was employed, beginning with an initial deep-plane facelift including extensive neck dissection, followed by a superficial parotidectomy on fresh-frozen cadavers. This approach allowed for a thorough exploration and mapping of the cervical nerve in relation to its surrounding anatomical structures.
    RESULTS: Upon exiting the parotid gland, the cervical nerve consistently traveled beneath the investing layer of the deep cervical fascia for a brief distance, traversing the deep fascia to travel within the areolar connective tissue before terminating anteriorly in the platysma muscle. A single branch was observed in 2 cases, while 2 branches were noted in 18 cases.
    CONCLUSIONS: The cervical nerve\'s relatively deeper position below the mandible\'s angle facilitates a safer subplatysmal dissection via a lateral approach for the release of the cervical retaining ligaments. Due to the absence of a protective barrier, the nerve is more susceptible to injuries from direct trauma or thermal damage caused by electrocautery, especially during median approaches.

    这项研究的目的是评估通过改良的耳内入路保护面神经的效果,并对浅表肌肉腱膜系统进行外周解剖,以进入颞下颌关节,从而获得出色的手术视野。颞下颌关节的多种外科手术,和改善术后即刻的一般护理,让这个手术变得不那么病态.这项研究包括33名患者(39侧),他们从2021年到2023年在位于波哥大的诊所“Colsanitas”的颌面部部门接受了颞下颌关节疾病的手术治疗,哥伦比亚。通过术后面神经损伤评估治疗效果,使用House-Brackman量表;手术后立即检查每位患者的面部肌肉组织功能。值得注意的是,零患者出现面神经损伤。这些结果表明,改良的耳内方法与浅表肌肉腱膜系统的外周解剖以进入颞下颌关节减少了面神经损伤的发生率,改善手术部位暴露,并降低并发症的发生频率。
    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.

    背景:由于皮肤松弛,整容手术曾经在60岁以上的人群中很常见,但是最近的趋势更倾向于这个年龄段的线程提升。了解姿势转变过程中面部解剖结构的动态变化至关重要。
    方法:新鲜的尸体研究表明,线穿过浅表肌肉和肌腱膜系统(SMAS)层,确认该技术的有效性。针对SMAS重新定位的适当插入深度,而不是皮肤表层,至关重要。
    结果:由线(N-Cog和N-Fix,N-FindersInc.,韩国)插入导致提升效应。然而,如果螺纹影响面部深层肌肉,可能会出现并发症,导致不适。纤维状隔片在引导丝线放置中起着重要作用,在提升过程中,不同的密度会影响螺纹的可操作性和组织反应。
    结论:针对使用螺纹的SMAS重新定位的程序旨在维持重新定位组织的新位置。了解面部区域的结构变化可通知线程选择和放置。使线与组织运动和预期的SMAS层定位对准对于防止并发症至关重要。平衡螺纹插入深度和组织牵引对于成功的结果至关重要。现代螺纹提升技术优先考虑SMAS重新定位,增强提升效果,同时确保程序的安全性和有效性。
    BACKGROUND: Face-lifting surgeries were once common among individuals over 60 years old due to skin laxity, but recent trends favor thread lifting in this age group. Understanding dynamic changes in facial anatomy during postural shifts is essential.
    METHODS: Fresh cadaver studies have demonstrated the passage of threads through the superficial musculoaponeurotic system (SMAS) layer, confirming the efficacy of the technique. Proper insertion depth targeting SMAS repositioning, rather than superficial skin layers, is crucial.
    RESULTS: The natural movement of tissues secured by thread (N-Cog and N-Fix, N-Finders Inc., Korea) insertion results in lifting effects. However, complications may arise if threads affect deeper facial muscles, leading to discomfort. Fibrous septa play a significant role in guiding thread placement, with different densities influencing thread maneuverability and tissue response during lifting.
    CONCLUSIONS: Procedures targeting SMAS repositioning using threads aim to maintain the new position of relocated tissues. Understanding structural variations in facial regions informs thread selection and placement. Aligning threads with tissue movement and the intended SMAS layer positioning is vital to prevent complications. Balancing thread insertion depth and tissue traction is critical for successful outcomes. Modern thread lifting techniques prioritize SMAS repositioning, enhancing lifting effects while ensuring procedure safety and efficacy.

    目的:颈面部浅表肌筋膜系统(SMAS)是由面部浅表筋膜的模拟肌肉和结膜组织形成的复杂网络。这项研究旨在介绍有关面部皮肤微灌注的跨SMAS分布模式重要性的新解剖功能数据,并强调SMAS在维持穿过它的血管网络的稳态中的作用。考虑到SMAS的纤维和肌肉基质,使用COLIII和MyoH2抗体,连同内皮免疫组织化学(IHC)细胞间粘附分子2标记,我们确定了这些结构的相关性及其相互作用。
    方法:这项研究包括33个SMAS组织的供体,已被常规苏木精和伊红(HE)染色,并使用了三种不同的IHC标记(胶原蛋白III,肌肉组织,和血管)。样本是从腮腺采集的,按摩师,jugal,和颧骨区域。磁共振血管造影术用于识别另外47名患者面部中外侧区域的主要血管来源。
    结果:地形布置的显著差异,密度,并观察了四个区域之间的显微血管关系。SMAS在每个地区的作用之间存在主要差异,从腮腺包膜到咬肌筋膜,过渡移动部分,和附着方式在颧骨亚基中。
    结论:血管形貌必须与周围的结膜和肌肉组织有关,特别是关于面部SMAS。SMAS的这三个组成部分与神经纤维之间的内在关系可以为我们提供有关整个系统功能的重要提示。
    OBJECTIVE: The superficial cervicofacial musculoaponeurotic system (SMAS) is a complex network formed by mimic muscles and conjunctive tissue of the superficial fascia of the face.This study aimed to introduce new anatomofunctional data on the importance of the trans-SMAS distribution pattern of the skin microperfusion of the face and to underline the role of SMAS in maintaining the homeostasis of the vascular network that crosses it. Considering the fibrous and muscular matrix of the SMAS, using COLIII and MyoH2 antibodies, together with endothelial immunohistochemistry(IHC)intercellular adhesion molecule 2 marker, we determined the correlation of these structures and their interaction.
    METHODS: This study included 33donors of SMAS tissues, which have been stained withregular hematoxylin and eosin (HE), and three different IHC markers have been used (collagen III, muscular tissue, and blood vessels). The samples were collected from parotid, masseteric, jugal, and zygomatic regions. Magnetic resonance angiography was used to identify the main vascular sources of the midlateral regions of the face of another 47 patients.
    RESULTS: Significant differences in topographic arrangement, density, and relations of the microsopic vasculature were observed between each of the four regions. Major differences were identified between the role of SMAS in each of these regions, from the parotid capsule to masseteric fascia, transition mobile part, and attaching manners in the zygomatic subunit.
    CONCLUSIONS: Blood vessel topography must be related with the surrounding conjunctive and muscular tissue, especially regarding facial SMAS. Intrinsic relations between these three components of the SMAS and nervous fibers can provide us important hints on the functionality of the whole system.

    BACKGROUND: This study evaluates change in practice patterns in facelift surgery based on a 15-year review of tracer data collected by the American Board of Plastic Surgery as part of the Continuous Certification process.
    METHODS: Tracer data for facelift was reviewed from 2006 to 2021. The 15-year collection period was divided into an \"early cohort (EC)\" from 2006 to 2014 and a \"recent cohort (RC)\" from 2015 to 2021.
    RESULTS: Of 3400 facelifts (1710 EC/1690 RC) performed, 18% were done in hospital and 76% were done in an accredited office facility. Ninety one percent of patients were female with an average age of 61 years. There was an increase in the number of secondary facelifts (4% EC vs 18% RC; p < 0.001) and an increased number of patients concerned about volume loss/deflation (25% EC vs 37% RC; p < 0.001). The surgical approach to the SMAS involved plication (40%), flaps (35%), SMASectomy (22%) and MACS lift (6%). One percent of facelifts were subperiosteal and 8% skin-only. Significantly more surgeons used the lateral SMAS flap (14% EC vs 18% RC, p < 0.005), while less used an extended SMAS flap (21% vs 18%; p = 0.001) and MACS lift (10% EC vs 6% RC; p = 0.021) techniques. The concomitant use of facial fat grafting is becoming more common (15% EC vs 24% RC, p = 0.0001).
    CONCLUSIONS: A 15-year review of ABPS tracer data provides an excellent venue for the objective assessment of the current status of facelift surgery, and key changes in practice patterns during that time.

    背景:随着颈部提升手术的患病率增加,通过不断发展的技术来增强颈部美学,该领域不断丰富。虽然许多最近的出版物关注深颈部手术,重要的是不要忽视颈缩轮廓作为颈部年轻化手术的一个重要方面的重要性。因此,我们想阐明我们独特的方法来勾勒鸭嘴兽轮廓。
    目的:本研究旨在评估渐进轮廓概念的疗效,一种技术,其中使用倒钩缝合线与其他治疗策略协同地重塑颈部。
    方法:我们的研究涵盖了2014年至2021年使用渐进式轮廓概念接受颈部年轻化治疗的337例患者。我们进行了回顾性审查,以评估术前和术后阶段使用Mirror软件的颈网膜角(CMA)的变化。
    结果:研究样本主要包括女性(337人中有304人),平均年龄为61岁(24-88岁)。大多数患者(95%)接受了深宫颈成形术,在所有情况下用于皮肤适应的手术网。经过14个月的中位随访,CMA值显著改善(从149.8°降至106.7°).在比较术前和术后结果时,这显示出统计学上的显着差异。
    结论:用倒刺缝线对颈部进行渐进塑形是一种有效的颈部年轻化技术。它利用多点和多矢量折叠,特别是与其他辅助手术结合时。
    BACKGROUND: As the prevalence of neck lift surgeries increases, the field is continually enriched by evolving techniques for enhancing neck aesthetics. While many recent publications focus on deep neck procedures, it is essential not to overlook the significance of platysmal contouring as an integral aspect of neck rejuvenation surgery. Accordingly, we would like to elucidate our unique approach to contouring the platysma.
    OBJECTIVE: This study was designed to assess the efficacy of the progressive contouring concept, a technique in which the neck is reshaped with barbed sutures synergistically with other treatment strategies.
    METHODS: Our study encompassed 337 patients who received neck rejuvenation treatment with the progressive contouring technique from 2014 to 2021. We conducted a retrospective review to evaluate the change in cervicomental angle (CMA) with Mirror software during the preoperative and postoperative stages.
    RESULTS: The study sample predominantly comprised females (304 out of 337), with a median age of 61 years (24-88). Most patients (95%) underwent deep cervicoplasty, with a surgical net applied in all cases for skin adaptation. After a median follow-up of 14 months, significant improvements were observed in CMA values (reduced from 149.8° to 106.7°). This demonstrated statistically significant differences when comparing preoperative and postoperative outcomes.
    CONCLUSIONS: Progressive shaping of the neck with barbed sutures is an effective technique in neck rejuvenation. It utilizes multipoint and multivector plication, particularly when integrated with other adjunctive surgical maneuvers.
