Thirty noses were examined macroscopically and histologically to determine the fibromuscular and aponeurotic layers. There are five soft-tissue components beneath the dermis: a superficial fatty panniculus, a fibromuscular layer, a deep fatty layer, a longitudinal fibrous sheet, and an interdomal ligament. The nose is covered by a nasal SMAS, which forms part of the SMAS of the face. The continuous fibromuscular layer interconnects the musculature through aponeuroses, thus distributing their forces. The alar muscles change the transnasal pressure of the nasal valve, affecting respiration. To preserve the integrity of the nasal soft-tissue layers, one may elevate the soft-tissue envelope beneath the nasal musculature.
对30个鼻子进行了宏观和组织学检查，以确定纤维肌肉层和腱膜层。真皮下方有五个软组织成分：浅表脂肪层、纤维肌肉层、深部脂肪层、纵向纤维片和鼻间隔韧带。鼻子由鼻SMAS覆盖，它是面部SMAS的一部分。连续的纤维肌肉层通过腱膜将肌肉组织相互连接，从而分散它们的力量。鼻翼肌改变鼻瓣膜的经鼻压力，影响呼吸。为了保持鼻软组织层的完整性，可以在鼻肌肉组织下方掀起软组织包膜。
