摘要

研究设计:描述性横断面。目的:探讨非洲人群鼻咽管(NPC)和鼻咽管深孔(IF)的形态学特征。方法:采用锥形束ct (Cone-Beam computed tomography, CBCT)扫描150例,测量鼻咽癌和中枢性脑出血。在鼻咽癌前的3个水平测量上颌骨厚度。采用独立t检验和卡方检验确定性别二态性的存在。结果:单侧斯坦森孔的存在最为普遍。鼻咽癌的平均长度为13.21±3.25 mm,男性鼻咽癌的管径明显较长。鼻咽癌矢状面呈圆柱状,冠状面呈单根管状。鼻咽癌与水平面的平均角度为118.42°。IF的平均尺寸分别为3.53 mm和3.07 mm,最常见的形状为圆形。男性上颌前骨较厚,且从鼻前棘向上至牙槽嵴下方的厚度普遍减少。结论:本研究突出了鼻咽癌和中鼻癌的解剖学特征,在Stenson孔的数量、鼻咽癌的长度、鼻咽癌和中鼻癌的形状以及鼻咽癌前的肺泡骨厚度等方面存在明显的性别二态性。

Anatomical Patterns of the Nasopalatine Canal and Incisive Foramen in an African Setting: A Cross-Sectional Study.

Study Design: Descriptive cross-sectional. Objective: To determine the morphology and morphometry of the nasopalatine canal (NPC) and incisive foramen (IF) in an African population. Methods: Measurements of the NPC and the IF were carried out on 150 Cone-Beam computed tomography (CBCT) scans. The maxillary bone thickness anterior to the NPC was measured at 3 levels. Independent t-test and Chi-square test were performed to determine the presence of sexual dimorphism. Results: The presence of one Stenson's foramen was most prevalent. The mean length of NPC was 13.21 ± 3.25 mm with significantly longer canals in males. The most prevalent shape of NPC was cylindrical in sagittal view and a single canal in coronal view. The mean angulation of NPC was 118.42° to the horizontal plane. The average dimensions of the IF were 3.53 mm and 3.07 mm in the anteroposterior and mediolateral diameter, respectively, while the most common shape was round. The anterior maxillary bone was thicker in males and generally reduced in thickness from the anterior nasal spine superiorly towards the alveolar crest inferiorly. Conclusion: This study highlights the anatomical characteristics of the NPC and IF, with significant sexual dimorphism observed regarding the number of Stenson's foramina, length of NPC, shapes of the NPC and IF, as well as alveolar bone thickness anterior to NPC.
