Abstract

Purpose: The nasal foramen is located in the nasal bone and for vessels passage to supply the nasal area. This project aimed to establish reliable references for the nasal foramina for future clinical applications.

Methods: The 72 dried skulls, 46 from the Division of Anatomy, University of Phayao, Thailand, and 26 from the Tulane University School of Medicine, USA, were collected and examined. The location, number, and sizes of nasal foramina were noted. The distances from each nasal foramen to the internasal suture, frontonasal suture, nasomaxillary suture, nasion, and rhinion were also recorded and used in the statistical analytical programs.

Results: The most common type of nasal foramen in all skulls was type II (one external opening) at 65.97%, followed by type I (no foramen opening) at 20.83%, type III (two external openings) at 11.11% and type IV at 2.08% (three external openings). Nasal foramen subtypes in many of the Thai and American skulls were type IIb and type IIa. The diameter of a connecting nasal foramen was significantly larger than that of a non-connecting. Results from embalmed confirmed the passage of the external nasal artery through the nasal cavity.

Conclusion: The study shows no significant difference in nasal foramen morphometry between Thai and American. It illustrates recent data on type and subtype classifications and the location of a vascular passage through the nasal foramen. This is the first study of NF variations and their respective classifications.

鼻孔解剖学研究。

目的：鼻孔位于鼻骨中，是供应鼻腔区域的血管通道。本项目旨在为鼻孔建立可靠的参考值，以便将来临床应用：收集并检查了 72 个干燥头骨，其中 46 个来自泰国帕夭大学解剖学系，26 个来自美国杜兰大学医学院。记录了鼻孔的位置、数量和大小。此外，还记录了每个鼻孔到鼻内缝、鼻前缝、鼻颌缝、鼻翼和鼻孔的距离，并将其用于统计分析程序：所有头骨中最常见的鼻孔类型是 II 型（一个外部开口），占 65.97%，其次是 I 型（无鼻孔开口），占 20.83%，III 型（两个外部开口），占 11.11%，IV 型（三个外部开口），占 2.08%。许多泰国和美国头骨中的鼻孔亚型为 IIb 型和 IIa 型。连接鼻孔的直径明显大于非连接鼻孔。防腐处理的结果证实外鼻动脉穿过鼻腔：研究表明，泰国人和美国人的鼻孔形态没有明显差异。它说明了有关类型和亚型分类以及血管通过鼻孔位置的最新数据。这是对 NF 变异及其各自分类的首次研究。

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.
