Abstract

Background: The frequent use of cone-beam computed tomography (CBCT) has drawn attention to the anatomical variations of the mandibular canal (MC). This study aimed to analyze the bifid mandibular canal (BMC) types, frequency, and impact of inferior alveolar nerve block (IANB).

Methods: This study included 142 CBCT scans. For the analysis of the BMC types, an established classification method was used. CBCT sagittal and transverse planes were used to analyze the occurrences, dimensions of the BMC types, and differences based on the sex and age of patients.

Results: The frequency of BMC was 9.2%. There were no statistically significant differences in the occurrence related to sex (P = 0.317), age (P = 1.000), or localization (P = 0.317). The average BMC diameter ranged from 1.2 to 2.5 mm. The largest BMC diameter was in the retromolar region.

Conclusion: The high incidence of BMC must be considered during IANB. Untimely identification of anatomic variations in the MC can lead to IANB anesthesia failure, as well as intraoperative and postoperative complications.

双裂下颌骨管评估及其与局部麻醉的相关性。

背景：锥形束计算机断层扫描（CBCT）的频繁使用引起了人们对下颌管（MC）解剖学变异的关注。本研究旨在分析下颌双裂管（BMC）的类型、频率和下牙槽神经阻滞（IANB）的影响。方法：本研究包括142张CBCT扫描。对BMC类型进行分析，采用已建立的分类方法。利用CBCT矢状面和横切面分析BMC类型的发生率、尺寸以及患者性别和年龄的差异。结果：BMC发生率为9.2%。与性别（P = 0.317）、年龄（P = 1.000）、定位（P = 0.317）相关的发生率无统计学差异。BMC的平均直径为1.2 ~ 2.5 mm。磨牙后区BMC直径最大。结论：IANB时应考虑BMC的高发。未及时识别MC的解剖变异可导致IANB麻醉失败，以及术中和术后并发症。
