Abstract

Purpose: To assess the prevalence and configuration of bifid (BMC) and trifid (TMC) mandibular canals using computed tomography (CT), describing the anatomical characteristics of the accessory canals, especially of the retromolar type.

Materials and methods: CT scans of 123 patients were analysed. BMCs were identified and the patterns of bifurcation were classified, including trifid canals. The width of accessory canals was measured. Retromolar canals were further classified according to their course and morphology, while their position and width were evaluated using linear measurements on CT images.

Results: The majority of patients (53.6%) presented at least one BMC or TMC. 36.2% of mandibular canals were bifid, while 4.5% were trifid. The forward canals (12.6%) and retromolar canals (10.2%) were the most common among BMCs. In relation to the retromolar canals, 60% were vertical and 40% curved, with a mean width of 1.03 ± 0.28mm.

Conclusion: BMCs and TMCs are common 3D radiographic findings, so that they should be considered as anatomical variations, not anomalies. Preoperative CT or CBCT evaluation should aid in identifying these variations and analysing their position and course in surgical planning.

下颌双叉管和三叉管的患病率和解剖学特征：计算机断层扫描分析

目的：使用计算机断层扫描（CT）评估下颌二叉管（BMC）和三叉管（TMC）的患病率和结构，描述附属管的解剖学特征，尤其是反磨型附属管的解剖学特征：分析了 123 名患者的 CT 扫描结果。材料：分析了 123 名患者的 CT 扫描图像，确定了 BMC，并对分叉模式进行了分类，包括三叉管。测量附属管道的宽度。根据其走向和形态对复极管进行进一步分类，并通过 CT 图像上的线性测量对其位置和宽度进行评估：大多数患者（53.6%）至少有一个 BMC 或 TMC。36.2%的下颌管为二叉，4.5%为三叉。在 BMCs 中，最常见的是前牙根管（12.6%）和后牙根管（10.2%）。在后齿槽管中，60%是垂直的，40%是弯曲的，平均宽度为 1.03 ± 0.28 毫米：结论：BMC 和 TMC 是常见的三维影像学结果，因此应将其视为解剖变异而非异常。术前 CT 或 CBCT 评估应有助于识别这些变异，并在手术规划中分析其位置和走向。
