Abstract

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.

关于中三分之一鼻腔皮肤动脉供血的尸体研究：对美容和整形手术的影响。

目的：通过尸体解剖详细检查鼻部皮肤中三分之一的动脉血供，确定主要动脉血源及其精确位置：方法：对新鲜标本的 14 个半面进行尸体解剖。在放大镜下仔细解剖了主要供血动脉及其分支。记录标本的形态特征、动脉及其分支在鼻部中段皮肤血管中的口径，并进行统计分析：结果：已确定四条主要动脉负责鼻腔中段皮肤的血液供应：面动脉、眶下动脉鼻支（nbIOA）、鼻背动脉和结肠丛上部分支。鼻外侧动脉（LNA）和 nbIOA 是主要的动脉分支来源，各自提供的动脉分支明显大于其他来源（LNA 为 1.8 ± 0.8 支，nbIOA 为 0.67 ± 0.2 毫米，P 值结论：LNA 和 nbIOA 在鼻腔中三分之一皮肤的动脉供血中发挥着关键作用。尽管血管解剖结构存在差异，但观察到的动脉供血模式一致，都汇聚在面唇沟的深度。了解这些模式对于提高手术精确度和降低美容与整形手术的并发症风险至关重要。

期刊介绍： Anatomy is a morphological science which cannot fail to interest the clinician. The practical application of anatomical research to clinical problems necessitates special adaptation and selectivity in choosing from numerous international works. Although there is a tendency to believe that meaningful advances in anatomy are unlikely, constant revision is necessary. Surgical and Radiologic Anatomy, the first international journal of Clinical anatomy has been created in this spirit. Its goal is to serve clinicians, regardless of speciality-physicians, surgeons, radiologists or other specialists-as an indispensable aid with which they can improve their knowledge of anatomy. Each issue includes: Original papers, review articles, articles on the anatomical bases of medical, surgical and radiological techniques, articles of normal radiologic anatomy, brief reviews of anatomical publications of clinical interest. Particular attention is given to high quality illustrations, which are indispensable for a better understanding of anatomical problems. Surgical and Radiologic Anatomy is a journal written by anatomists for clinicians with a special interest in anatomy.
