Abstract

Purpose: Understanding the detailed course of the septal branch of the superior labial artery is crucial for improving the safety and efficacy of both invasive and noninvasive nasal procedures. This study aimed to clarify the anatomical courses and variations of the deep and superficial septal branches of the superior labial artery in the columella, with particular attention paid to their clinical implications in rhinoplasty and reconstructive surgeries.

Methods: The deep and superficial septal branches of the superior labial artery were examined in 40 Korean embalmed cadavers. Detailed dissections were performed to trace the course of the septal branch, measure its diameter, and document its branching patterns.

Results: The deep septal branch of the superior labial artery arose from the middle portion of this artery, coursing anteriorly just below the septal cartilage. It emerged between the superior border of the orbicularis oris and the septal cartilage, ascending toward the nasal tip in 90.0% of cases. The branch divided into two main branches at the upper (27.5%), middle (5.0%), and lower (47.5%) levels of the columella. In another 10.0% of cases the branch either did not ascend to the columella or only reached the middle level. The superficial septal branch was found to anastomose with the deep septal branch at the columellar base in several cases, and its diameter varied, being thicker than the deep septal branch in some cases. The superficial septal branch also exhibited various branching patterns that contributed significantly to the vascularization of the columella and nasal tip.

Conclusion: This study has yielded comprehensive anatomical data on the deep and superficial septal branches of the superior labial artery, highlighting its clinical significance in nasal surgeries and procedures. These findings offer valuable insights for optimizing procedural outcomes and minimizing complications in rhinoplasty and reconstructive surgeries.

唇上动脉鼻中隔深浅支在鼻梁和鼻尖的解剖走向及其在鼻整形和鼻部重建手术中的应用。

目的：了解唇上动脉鼻中隔分支的详细路线对提高有创和无创鼻手术的安全性和有效性至关重要。本研究旨在阐明唇上动脉鼻中隔深浅支在鼻小柱处的解剖过程和变化，并特别关注其在鼻整形和重建手术中的临床意义。方法：对40具朝鲜族尸体进行唇上动脉间隔深支和间隔浅支检查。进行了详细的解剖，以追踪间隔分支的路线，测量其直径，并记录其分支模式。结果：唇上动脉鼻中隔深支起源于鼻中隔动脉中段，在鼻中隔软骨下方向前走行。它出现在口轮匝肌上缘和鼻中隔软骨之间，90.0%的病例向鼻尖方向上升。分支在小柱的上（27.5%）、中（5.0%）和下（47.5%）水平分为两个主要分支。在另外10.0%的病例中，分支要么没有上升到小柱，要么只达到中间水平。中隔浅支在小柱基部与中隔深支吻合，其直径变化较大，有的较中隔深支粗。鼻中隔浅支也表现出不同的分支模式，这对鼻梁和鼻尖的血管化有重要的贡献。结论：本研究获得了完整的唇上动脉间隔深支和间隔浅支的解剖学资料，突出了其在鼻外科手术中的临床意义。这些发现为优化鼻整形和鼻重建手术的手术效果和减少并发症提供了有价值的见解。

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.
