In planning a skin graft, the texture, color, and size of the recipient and donor site tissues should be considered.
We determined the optimal donor sites for nasal full-thickness skin grafting based on biophysical parameters.
Thirty women over the age of 60 were selected for this study. Four recipient sites (nasal root, dorsum, tip, ala) and three donor sites (preauricle, postauricle, forehead) were considered. Biophysical parameters such as transepidermal water loss (TEWL), capacitance, sebum output, erythema/melanin value, and skin replica technique were tested.
The nasal root was correlated with the forehead in terms of TEWL and sebum output. The nasal dorsum was correlated with the preauricle in terms of TEWL, erythema/melanin value, and skin replica measurements. The nasal tip was correlated with the preauricle in terms of TEWL, sebum output, erythema/melanin value, and skin replica measurements. The ala was correlated with the forehead in terms of TEWL and skin replica measurements.
The preauricule is the optimal donor site for resurfacing of the nasal dorsum and tip. The forehead is a good donor site for alar defects. For resurfacing of the nasal root, the forehead and postauricle are good choices.
在计划进行皮肤移植时，应考虑受区和供区组织的质地、颜色和大小。
我们基于生物物理参数确定鼻全层皮肤移植的最佳供区。
本研究选取了30名60岁以上的女性。考虑了四个受区（鼻根、鼻背、鼻尖、鼻翼）和三个供区（耳前、耳后、前额）。测试了经表皮水分流失（TEWL）、电容、皮脂分泌、红斑/黑色素值和皮肤复模技术等生物物理参数。
鼻根在TEWL和皮脂分泌方面与前额相关。鼻背在TEWL、红斑/黑色素值和皮肤复模测量方面与耳前相关。鼻尖在TEWL、皮脂分泌、红斑/黑色素值和皮肤复模测量方面与耳前相关。鼻翼在TEWL和皮肤复模测量方面与前额相关。
耳前是鼻背和鼻尖修复的最佳供区。前额是鼻翼缺损的良好供区。对于鼻根修复，前额和耳后是不错的选择。
