Soft tissue thickness (STT) is a major factor affecting the outcome in rhinoplasty. However, limited information is found in the literature on the age- and gender-related variations of the nasal STT.
The purpose of this study was to measure STT at various landmarks over the nasal framework and compare the age- and gender-related differences.
STT measurements were made at 11 landmarks in 325 patients by employing magnetic resonance imaging. Patients were divided into subgroups to compare the STT differences between female and male and between the age groups as young, middle age, and elderly.
Soft tissue was thickest at the nasion and thinnest at the rhinion. The soft tissue coverage was significantly thicker in the male population at the supratip, tip, nasal bones, upper lateral cartilages, and alar lobules, whereas it is thicker in females at the rhinion. Average thickness of the soft tissues over the entire nasal framework increases with age except the rhinion.
The STT is variable over different parts of the osteocartilaginous framework. Gender and age influence the STT. The soft tissue is thicker at the distal half of the nose in male patients, and these areas become gradually thicker with age, whereas the soft tissue over the midvault becomes thinner. Increasing age presents a particular challenge to achieve predictable results in rhinoplasty, and an understanding of the soft tissue envelope allows for improved aesthetic outcome.
软组织厚度（STT）是影响鼻整形术效果的主要因素。然而，文献中关于鼻 STT 的年龄和性别相关变化的信息有限。
本研究旨在测量鼻支架各标志点的 STT，并比较年龄和性别相关的差异。
通过磁共振成像对 325 名患者的 11 个标志点进行 STT 测量。将患者分为亚组，比较女性和男性之间以及年轻、中年和老年组之间的 STT 差异。
鼻根部的软组织最厚，鼻翼缘最薄。在鼻尖、鼻翼、鼻骨、上外侧软骨和鼻翼小叶等部位，男性的软组织覆盖明显较厚，而在鼻翼缘，女性的软组织覆盖较厚。除了鼻翼缘外，整个鼻支架上的软组织平均厚度随年龄增长而增加。
STT 在不同的骨软骨支架部位是可变的。性别和年龄影响 STT。男性患者鼻远端的软组织较厚，这些部位随年龄逐渐增厚，而中隔的软组织变薄。年龄的增长给鼻整形术带来了实现可预测效果的特殊挑战，对软组织包膜的理解可以提高美学效果。
