Abstract

Purpose: This study aimed to determine the presence and incidence of accessory sutures and bipartite zygomatic bone types, and their effects on population affinity and clinical significance.

Methods: We examined 120 dry skulls and 50 zygomatic bones to evaluate the presence, frequency, and location of accessory zygomatic sutures as well as subtypes of bipartite zygomatic bones. Morphometric analysis included measuring the total width and length of the zygomatic bone with accessory sutures (ASs), the total length of the AS, and the shortest distance between the AS and various anatomical landmarks.

Results: Bipartite zygomatic bone was observed in 14 of 120 dry skulls (11.6%) and 1 of 50 zygomatic bones (2%), indicating an overall incidence of 16 occurrences (8.82%). The ASs were predominantly located posterolaterally in 11 cases (six males, five females), anteromedially in two cases (one male, one female), superiorly in one case (male), and superolaterally in one case (male). Significant differences were noted in the distribution of the ASs (p < 0.001). Notably, a vertical inferior bipartite zygomatic type, which has not been reported in the literature, was identified. Correlations were observed between the various anatomical landmarks. Among females, the length of AS was significantly different (p = 0.038). Significant differences were also noted in the shortest distance between the AS and the zygomaticofacial foramen (ZFF) based on the body side (p = 0.034).

Conclusions: Our study suggests that the bipartite zygomatic bone is not a common occurrence, indicating its significance as a morphological variation present in certain individuals. The type VII bipartite zygomatic bone exhibited the highest incidence rate, suggesting potential ethnic-specific differences in the prevalence of certain subtypes. The consistent pattern of suture distribution, along with the asymmetry and variability in suture patterns, emphasizes its potential clinical relevance.

评估干燥头骨中附属颧骨缝的频率和可变性：临床见解和潜在影响。

目的：本研究旨在确定附属颧骨缝和双节颧骨类型的存在和发生率，以及它们对人群亲和性和临床意义的影响：我们检查了 120 个干头骨和 50 块颧骨，以评估附属颧缝和双节颧骨亚型的存在、频率和位置。形态计量分析包括测量带有附属缝的颧骨的总宽度和总长度、附属缝的总长度以及附属缝与各种解剖标志之间的最短距离：在120个干头骨中有14个（11.6%）观察到双节颧骨，在50个颧骨中有1个（2%）观察到双节颧骨，总发生率为16次（8.82%）。11例（男性6例，女性5例）AS主要位于后外侧，2例（男性1例，女性1例）位于前内侧，1例（男性）位于上侧，1例（男性）位于上外侧。在 AS 的分布上存在显著差异（P 结论：AS 的分布存在显著差异：我们的研究表明，双节颧骨并不常见，这表明它是存在于某些个体中的一种形态变异。VII 型双节颧骨的发病率最高，这表明某些亚型的发病率可能存在种族差异。缝合线分布的一致模式以及缝合线模式的不对称和变异性强调了其潜在的临床意义。

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.
