OBJECTIVE
The aim of this study was to analyze the rate, location, and characteristics of bifid mandibular canals (BMCs) in the population of the Shanghai area using cone beam computed tomography to avoid complications during surgical procedures.
METHODS
Two hundred eighty patients were recruited for this study, and the presence and morphology of BMCs were evaluated.
RESULTS
The occurrence rate of BMCs in the Shanghai area was relatively high compared with that in other populations, reaching 31.1%. In addition, the study also found some far less-common trifid mandibular canals, as well as a peculiarly shaped special type, which we called v-type canal that has yet to be described.
CONCLUSIONS
Our study underlined the different characteristics and occurrence rates of BMCs in the population of the Shanghai area and the importance of using cone beam computed tomography for a reliable detection, providing useful information to help prevent presurgery and postsurgery complications.
目的
本研究旨在利用锥形束计算机断层扫描分析上海地区人群中双下颌管（BMCs）的发生率、位置及特征，以避免手术过程中出现并发症。
方法
招募280例患者参与本研究，评估BMCs的存在情况及形态。
结果
与其他人群相比，上海地区BMCs的发生率相对较高，达31.1%。此外，该研究还发现了一些极为罕见的三下颌管，以及一种形状奇特的特殊类型，我们称之为尚未见报道的V型管。
结论
我们的研究强调了上海地区人群中BMCs的不同特征和发生率，以及使用锥形束计算机断层扫描进行可靠检测的重要性，为预防术前和术后并发症提供了有用信息。
