The submuscular aponeurotic system (SMAS) has been steeped in controversy. The goal of our anatomic study was to further clarify the existence of the SMAS. With an operating microscope, we performed dissections in 10 fresh cadaver heads (20 hemiheads) exposing the SMAS through a face lift incision. Through the operating microscope we were able to identify the SMAS and its relationship to other anatomic structures. Full-thickness longitudinal sections were obtained for routine histologic studies along various surgically relevant regions of the SMAS. In addition, dissections were accomplished with the operating microscope on 12 rhesus monkey fetuses ranging in age from a few weeks to 8 months. Data obtained from the fresh cadaver microdissections, topographic histology, and comparative anatomy revealed the presence of the SMAS as a distinct fibromuscular layer composed of the platysma muscle, parotid fascia, and fibromuscular layer covering the cheek.
肌下腱膜系统（SMAS）一直备受争议。我们进行解剖学研究的目的是进一步阐明SMAS的存在。我们使用手术显微镜，在10个新鲜尸体头部（20个半侧头部）进行解剖，通过除皱切口暴露SMAS。通过手术显微镜，我们能够识别SMAS及其与其他解剖结构的关系。沿着SMAS的各个手术相关区域获取全层纵向切片用于常规组织学研究。此外，使用手术显微镜对12只年龄从几周至8个月不等的恒河猴胎儿进行解剖。从新鲜尸体显微解剖、局部组织学和比较解剖学获得的数据表明，SMAS作为一个独特的纤维肌肉层存在，该层由颈阔肌、腮腺筋膜和覆盖脸颊的纤维肌肉层组成。
