Abstract

Background: Careful anatomical investigation of canalis sinuosus (CS) is essential to prevent damage to blood vessels and nerves in this area during surgical procedures, such as placing dental implants in the anterior maxillary region. This study investigated the relationship and distance between the CS and its adjacent structures.

Methods: A total of 400 cone-beam computed tomography (CBCT) images of Iranian adults aged 20-86 years were included in this retrospective study. Two observers assessed all the images twice with a time interval of one month. The closest tooth to the CS, its position relative to the CS, and distance measurements of the CS from adjacent structures were determined.

Results: CS was found in 10.5% of all images. The mean diameter of the canal was 1.06±0.29 mm, which was not significantly different between the age groups, right and left sides, or genders. The most common location of CS was mid-position relative to the upper lateral incisors. In linear measurements, only the distance from the CS to the buccal cortical plate and perpendicular to the nasopalatine canal exhibited a significant difference between the two sexes, with no significant difference between the right and left sides.

Conclusion: CS location was significantly more palato-lateral in males. There was no significant difference in the prevalence between the two sexes.

锥形束计算机断层图像中相对于相邻结构的管状窦的定量评价。
背景:在外科手术中,如在上颌前区放置种植体时,对窦管(CS)进行仔细的解剖研究是防止该区域血管和神经损伤的必要条件。本研究探讨了骶椎体与其相邻结构之间的关系和距离。方法:回顾性分析400例年龄在20-86岁的伊朗成年人的ct图像。两名观察员以一个月的时间间隔对所有图像进行两次评估。测定离中枢性牙最近的牙齿、相对于中枢性牙的位置以及中枢性牙与邻近结构的距离。结果:10.5%的图像出现CS。根管平均直径为1.06±0.29 mm,年龄、左右侧、性别间差异无统计学意义。CS最常见的位置是相对于上侧切牙的中间位置。在线性测量中,只有CS到颊皮质板和垂直于鼻腭管的距离在两性之间有显著差异,左右两侧无显著差异。结论:男性CS位置明显偏向腭外侧。两性之间的患病率没有显著差异。
