There is no evidence about evaluating accessory infraorbital foramen by 3-dimensional analysis like multi slice computed tomography or cone beam computed tomography (CBCT) in human subjects. To authors' best knowledge this is a first study to assess the accessory infraorbital foramen and position of infraorbital foramen in relation to crown of maxillary teeth using CBCT. This study primarily aimed to assess the location and number of accessory infraorbital foramen (AIOF), to measure the distance between main infraorbital foramen and AIOF and secondarily to determine the position of infraorbital foramen in relation to crowns of maxillary second premolar, first molar, and second molar. Cone beam computed tomography volumes of 200 patients were retrieved from the digital imaging and communications in medicine archive folder. Accessory infraorbital foramen was recognized in 29% of the patients among whom 46.6% were present on the right side, 31% on the left side, and 22.4% located bilaterally. The most frequent position of infraorbital foramen was found to be in line with crown of second premolar. The presence of AIOF and inability to recognize it in preoperative evaluation could be considered among the other reasons of failure or incomplete anesthesia.
目前尚无关于在人体中通过多层计算机断层扫描或锥形束计算机断层扫描（CBCT）等三维分析来评估眶下副孔的证据。据作者所知，这是第一项使用CBCT评估眶下副孔以及眶下孔相对于上颌牙齿牙冠位置的研究。本研究的主要目的是评估眶下副孔（AIOF）的位置和数量，测量主眶下孔与AIOF之间的距离，其次是确定眶下孔相对于上颌第二前磨牙、第一磨牙和第二磨牙牙冠的位置。从医学数字成像和通信存档文件夹中检索了200例患者的锥形束计算机断层扫描图像。29%的患者存在眶下副孔，其中右侧占46.6%，左侧占31%，双侧占22.4%。发现眶下孔最常见的位置与第二前磨牙的牙冠在一条直线上。AIOF的存在以及在术前评估中未能识别它可能被视为麻醉失败或不完全的其他原因之一。
