The thickness of the nasal soft tissue envelope (STE) plays a crucial role in the final rhinoplasty results. The Asian nasal contour is typically characterized by a thicker STE and broader nasal tip, but objective data are lacking. The purpose of this study was to objectively measure nasal dermal thickness and overall STE thickness and to determine any demographic differences.
From July to September 2023, 110 patients presenting for consultation underwent ultrasound evaluation of their nasal STE. STE thickness was measured at predetermined subsites and compared with published data on white patients.
The thickness of the STE in Asian patients was greater than that in white patients. The STE was thickest at the supratip (mean [SD]), (4.88 [0.74] mm) rather than at the nasion and thinnest at the rhinion (2.25 [0.51] mm). The nasal tip (4.07 [0.72] mm) showed comparable STE thickness with the nasion (4.13 [0.72] mm) but had a significantly thicker dermis than the nasion (2.35 ± 0.49 mm vs. 1.35 ± 0.35 mm, P < 0.05). Male sex and higher BMI tended to be correlated with a thicker nasal STE, but age did not show any relationship. A thicker nasal tip STE showed significantly greater nasal tip width and nasal alar thickness.
STE thickness at different nasal subsites varies and affects external nasal contour and rhinoplasty outcomes.

鼻软组织包膜（STE）的厚度对最终隆鼻效果起着关键作用。亚洲人的鼻外形通常特点是STE较厚且鼻尖较宽，但缺乏客观数据。本研究的目的是客观测量鼻真皮厚度和整体STE厚度，并确定是否存在人口统计学差异。
2023年7月至9月，110名前来咨询的患者接受了鼻STE的超声评估。在预定的亚部位测量STE厚度，并与已发表的白人患者数据进行比较。
亚洲患者的STE厚度大于白人患者。STE在鼻尖上方最厚（平均[标准差]，（4.88[0.74]mm），而非鼻根处，在鼻小柱基部最薄（2.25[0.51]mm）。鼻尖（4.07[0.72]mm）的STE厚度与鼻根（4.13[0.72]mm）相当，但真皮明显比鼻根厚（2.35±0.49mm对1.35±0.35mm，P<0.05）。男性和较高的BMI往往与较厚的鼻STE相关，但年龄未显示出任何关系。较厚的鼻尖STE显示出明显更宽的鼻尖宽度和鼻翼厚度。
不同鼻亚部位的STE厚度不同，会影响鼻外形和隆鼻效果。
