    背景:当脸颊区域的面部肿块与临床怀疑为腮腺起源的高指数相关时,预防性腮腺切除术总是进行。我们报告了一例罕见的神经鞘瘤病例,该病例被怀疑是腮腺起源的,使用改良的Blair切口和浅表肌肌腱膜系统(SMAS)层折叠方法进行了成功的手术治疗。
    方法:一名27岁的妇女到医院对一家公司进行评估,固定,非压痛肿块(2.5厘米×3.5厘米),位于右耳前方,1年的持续时间。对比增强的面部计算机断层扫描显示,低密度肿块粘附在右腮腺浅叶,临床怀疑副腮腺肿块的高指数。该患者计划接受肿块切除术和浅表腮腺切除术。她用改良的布莱尔切口做了手术,SMAS层向后折叠以重建缺损。组织病理学检查证实了神经鞘瘤的诊断。,我们没有观察到血肿等术后并发症,感染,或者面部表情异常.术后2个月切口瘢痕不明显,面部轮廓保持在受影响和未受影响的两侧之间没有任何差异。
    结论:我们使用了改良的Blair切口和SMAS层折叠方法,在脸颊区域切除了一种罕见的神经鞘瘤并进行了浅表腮腺切除术后,获得了良好的美学效果。
    BACKGROUND: When a firm facial mass in the cheek region is associated with a high index of clinical suspicion of its being of parotid gland origin, preventive parotidectomy is invariably performed. We report a rare case of a schwannoma that was suspected to be of parotid gland origin in a patient, who underwent successful surgical management using a modified-Blair incision and superficial musculoaponeurotic system (SMAS) layer folding method.
    METHODS: A 27-year-old woman presented to the hospital for evaluation of a firm, fixed, non-tender mass (2.5 cm × 3.5 cm), located anterior to the right ear, of 1 year\'s duration. Contrast-enhanced facial computed tomography revealed a well-encapsulated, low-density mass adherent to the superficial lobe of the right parotid gland, with a high index of clinical suspicion of an accessory parotid gland mass. The patient was scheduled to undergo resection of the mass and superficial parotidectomy. She underwent surgery using a modified-Blair incision, and the SMAS layer was folded posteriorly to reconstruct the defect. Histopathological examination confirmed the diagnosis of a schwannoma., and we observed no postoperative complications such as hematoma, infection, or abnormal facial expressions. The incision scar was unnoticeable 2 mo postoperatively, and the facial contour was maintained without any differences between the affected and unaffected sides.
    CONCLUSIONS: We used a modified-Blair incision and SMAS layer folding method to achieve aesthetically good results following resection of a rare schwannoma with superficial parotidectomy in the cheek region.

    背景:面部衰老是一个多因素的过程,会影响面部解剖结构的每个组成部分。整容技术的两个通用组是浅表肌肌腱膜系统(SMAS)抬高和SMAS操纵。本文的目的是描述和比较优点,缺点,以及整容技术的局限性。
    方法:进行了系统评价,以描述整容技术的当前结果证据。根据指定的面部评估标准,选择了一个子队列的文章进行基于案例的分析。进行分析以确定优势,缺点,以及每种技术的局限性。
    结果:共选择65篇文章进行系统评价,其中15篇文章符合基于病例的评价标准。对于各种整容技术,患者的满意度被认为是模棱两可的。每种整容技术的特定优缺点取决于皮肤移位矢量的技术方法及其动员浅表面部脂肪的程度。面部脂肪移植普遍适用于修复深颌骨体积。根据SMAS技术的不同,面部脂肪移植的使用也有所不同,以解决其特定的局限性。
    结论:我们的综述证实,有许多方法可以在面部年轻化中获得优异的效果。经验丰富的外科医生能够在了解个体患者审美需求的基础上,通过各种技术获得一致的结果,被操纵的软组织的质量,以及如何改变一种特定的技术来达到所需的美学终点。
    Facial aging is a multifactorial process that affects each component of facial anatomy. The two general groups of face lift techniques are superficial musculoaponeurotic system (SMAS) elevation and SMAS manipulation. The purpose of this article is to describe and compare the advantages, disadvantages, and limitations of face lift techniques.
    A systematic review was performed to describe current outcomes evidence for face lift techniques. A subcohort of articles was selected for case-based analysis based on designated facial assessment criteria. Analysis was performed to determine the advantages, disadvantages, and limitations of each respective technique.
    A total of 65 articles were selected for systematic review, of which 15 met criteria for case-based review. Patient satisfaction was found to be equivocal for various face lift techniques. Specific advantages and disadvantages for each face lift technique were dependent on the techniques\' approach to skin shift vector along with its degree of mobilizing superficial facial fat. Facial fat grafting was universally applicable for restoration of deep malar volume. Facial fat grafting was also used differently depending on the SMAS technique to address its specific limitations.
    The authors\' review confirms that there are many methods to obtain excellent outcomes in facial rejuvenation. Experienced surgeons are able to obtain consistent results through a variety of techniques based on understanding the aesthetic needs of the individual patient, the quality of the soft tissues being manipulated, and how to vary a specific technique to reach desired aesthetic end points.

    Contractures to the cervical region as a result of burns has the capacity to cause restrictions in range of movement, function of the lower face, cervical spine distortion and poor aesthetic outcomes that remain a surgical challenge. Consequently, physical and aesthetic deformities as a result of cervical contractures are reported to cause depression having implications for patients\' quality of life and psychosocial wellbeing. At the time this research was conducted, there were no case reports describing a closed platysmotomy approach in burn patients. In this article, we review the literature surrounding closed platysmotomies and present what we believe to be the first reported case in the treatment of cervical contractures utilising a closed platysmotomy approach in a burns patient. A closed platysmotomy approach for the treatment of cervical contractures is a less invasive technique. Further investigation is warranted to determine the feasibility of this reconstructive approach in the area of burn scar management.
