Nasal skin and soft tissue envelope (SSTE) thickness has considerable effects on procedural planning and postoperative outcomes in rhinoplasty surgery. Objective understanding of relative SSTE thickness in patients is essential to optimal outcomes in rhinoplasty, and knowledge of its variation by demographic group is of aid to surgeons. To measure and compare nasal SSTE thickness across different races and nasal subsites and to determine whether objective variability exists for these parameters. Retrospective cross-sectional radiographic analysis was carried out on 200 adult patients, without nasal deformity, presenting to an academic otolaryngology clinic at a tertiary care academic referral center. Blinded evaluators measured nasal SSTE thickness at six sites on maxillofacial computed tomography (CT) scans and comparisons were made based on patient-reported race/ethnicity categories available in the electronic medical record. N/A Nasal SSTE thickness was measured at six predefined anatomic sites using high-resolution CT imaging. Statistical comparisons between races/ethnicities were made based on these measurements. Mean age of patients was 48.8 years, and 47% were male. Nasal SSTE showed thicker soft tissue at the sellion in Latin American (LA; mean (SD) 6.1 (1.8) mm) and white (5.8 (1.8) mm) patients vs. African American (AfA) and Asian American (AsA) patients. The supratip was thicker in AfA patients (5.2 (1.3) mm) vs. all other races. The tip SSTE was thinner in white patients (2.4 (0.7) mm) vs. all other races. Composite nasal SSTE thickness was thinner in AsA patients (3.22 (0.8) mm) relative to AfA and LA patients. SSTE thickness influences surgical planning and postoperative outcomes in rhinoplasty patients. This study supports varied thickness of the nasal SSTE among patients of different races. These data are foundational in providing a framework for developing treatment strategies specific to the SSTE properties of a multicultural patient population.
鼻皮肤和软组织包（SSTE）厚度在鼻整形手术的程序规划和术后结果中有很大的影响。客观了解患者的相对 SSTE 厚度对于鼻整形术的最佳效果至关重要，了解其按人口统计学分组的变化有助于外科医生。测量并比较不同种族和鼻亚部位的鼻 SSTE 厚度，并确定这些参数是否存在客观差异。对 200 名无鼻畸形的成年患者进行了回顾性横断面放射分析，这些患者在一家三级保健学术转诊中心的学术耳鼻喉科诊所就诊。在颌面计算机断层扫描（CT）扫描的六个部位，由盲法评估员测量鼻 SSTE 厚度，并根据电子病历中提供的患者报告的种族/族裔类别进行比较。使用高分辨率 CT 成像在六个预先定义的解剖部位测量鼻 SSTE 厚度，并根据这些测量值对种族/族裔进行统计比较。患者的平均年龄为 48.8 岁，其中 47%为男性。鼻 SSTE 在拉丁美洲（LA；平均（SD）6.1（1.8）mm）和白人（5.8（1.8）mm）患者的蝶鞍处显示出更厚的软组织，而在非裔美国人和亚裔美国人（AsA）患者中。AfA 患者的鼻尖更厚（5.2（1.3）mm）。白人患者的鼻尖 SSTE 较薄（2.4（0.7）mm）。与 AfA 和 LA 患者相比，AsA 患者的复合鼻 SSTE 厚度更薄（3.22（0.8）mm）。SSTE 厚度会影响鼻整形患者的手术计划和术后结果。本研究支持不同种族患者的鼻 SSTE 厚度存在差异。这些数据为针对多元文化患者人群的 SSTE 特性制定治疗策略提供了基础。
