<p>This study aimed to evaluate the correlation between external nasal measurements and the size of harvestable septal cartilage in cadaveric specimens, with the potential to improve surgical planning for graft harvesting in rhinoplasty.

摘要

This study aimed to evaluate the correlation between external nasal measurements and the size of harvestable septal cartilage in cadaveric specimens, with the potential to improve surgical planning for graft harvesting in rhinoplasty. In 26 cadaveric specimens, two external nasal measurements were obtained: from the rhinion to the palpable end of the septal cartilage (RH–PEC), and from the palpable end of the septal cartilage to the subnasale (PEC–SN). The nasal septum was then harvested, and the dorsal and caudal lengths were measured. Correlation analyses were performed between RH–PEC and dorsal length, and between PEC–SN and caudal length. Septal thickness and surface area were also recorded. The mean external measurements were 2.28 cm (RH–PEC) and 1.79 cm (PEC–SN), while the mean internal measurements were 2.48 cm (dorsal) and 1.83 cm (caudal). A statistically significant correlation was found between PEC–SN and caudal cartilage height (p = 0.009), and a linear equation was proposed for predictive estimation. No significant correlation was observed between RH–PEC and dorsal length. This study shows a correlation between the external measurement PEC–SN and harvestable caudal septal cartilage size, with a proposed equation to assist preoperative planning. However, Thai individuals have smaller septal lengths and surface areas than reported in Caucasian, Indian, and Chinese populations. Septal cartilage alone was often insufficient for complete rhinoplasty, highlighting the need for alternative graft sources and thorough preoperative counseling.
