Abstrakt: Purpose: To provide a detailed examination of the arterial blood supply to the middle third of the nasal skin through cadaveric dissections, identifying the primary arterial sources and their precise locations.
Methods: Cadaveric dissections were performed on 14 hemifaces from fresh specimens. The main feeding arteries and their branches were carefully dissected under magnification. Morphometric characteristics of the specimens, along with the caliber of the arteries and their branches vascularizing the mid-third nasal skin were recorded, and statistically analyzed.
Results: Four main arteries were identified as responsible for the blood supply to the mid-third of the nasal skin: the facial artery, the nasal branch of the infra-orbital artery (nbIOA), the dorsal nasal artery, and the upper branches of the columellar plexus. The lateral nasal artery (LNA) and the nbIOA were the main contributors, each providing significantly larger arterial branches than the other sources (1.8 ± 0.8 branches of 0.67 ± 0.2 mm for the LNA, p-value < 0.001-1 ± 0 branches of 0.55 ± 0.17 mm for the nbIOA, p-value < 0.01). The largest arterial branch consistently penetrated the lateral and inferior angle of the mid-third nasal skin, originated either from the LNA or nbIOA.
Conclusion: The LNA and nbIOA endorse crucial roles in the arterial blood supply to the mid-third nasal skin. Despite the variability in vascular anatomy, a consistent pattern of arterial supply with convergence in the depth of the alarfacial groove was observed. Understanding these patterns is vital for improving surgical precision and reducing the risk of complications in both aesthetic and reconstructive surgeries.
