Abstract

The knowledge of the location of the infraorbital foramen (IOF) is crucial in the management of maxillofacial surgeries. The morphology of this foramen is variable in different populations. The purpose of this study is to locate the IOF and to determine the frequency and location of accessory IOF (AIOF) in the Indian population. The study was conducted after getting ethical approval from the institutional review board. It was done on the 60 hemi faces of formalin embalmed heads of 30 cadavers. A modified Weber–Fergusson’s incision was made to expose the anterior surface of the maxilla and the distance of IOF from the root of PM2 teeth and the infraorbital rim (IOR) was measured. The occurrence of AIOF was noted and the neurovascular structures passing through were traced. The distance of the AIOF from the IOF was measured and the statistical analysis was done. The mean distance of the IOF to the IOR on the right side was 6.96 ± 1.79 mm and on the left side was 7.24 ± 1.84 mm. The mean distance of the IOF from the upper PM2 on the right side was 27.11 ± 5.16 mm and on the left side was 26.71 ± 5 mm. The AIOF was present in 10 % of the cadavers dissected and supero-medial in position. It may be single or double, transmitting blood vessels and nerves. The mean distance between the IOF to the AIOF was 9.92 mm on the right and 5.87 mm on the left. Until now, no studies have been conducted on human cadavers to determine if any neurovascular structures pass through AIOF in Indian populations. This human cadaveric study will give additional information to the clinicians that a considerable number of patients may have AIOF and they may transmit neurovascular structures, the knowledge of this is needed to avoid unexpected complications during surgical procedures and nerve block.
通过尸体观察印度人的眶下孔和附属眶下孔
了解眶下孔(IOF)的位置对于颌面外科手术的管理至关重要。眶下孔的形态在不同人群中存在差异。本研究的目的是确定 IOF 的位置,并确定印度人群中附属 IOF(AIOF)的频率和位置。 这项研究是在获得机构审查委员会的伦理批准后进行的。研究对象是 30 具尸体的 60 个半面福尔马林防腐头颅。采用改良的韦伯-费尔古森切口暴露上颌骨前表面,测量 IOF 与 PM2 牙根和眶下缘 (IOR) 的距离。记录 AIOF 的发生情况,并追踪穿过的神经血管结构。测量 AIOF 与 IOF 的距离并进行统计分析。 右侧 IOF 到 IOR 的平均距离为 6.96 ± 1.79 毫米,左侧为 7.24 ± 1.84 毫米。右侧 IOF 距 PM2 上端的平均距离为(27.11 ± 5.16)毫米,左侧为(26.71 ± 5)毫米。在解剖的尸体中,10%存在AIOF,其位置在上内侧。它可能是单层或双层的,传输血管和神经。IOF与AIOF之间的平均距离右侧为9.92毫米,左侧为5.87毫米。 到目前为止,还没有在人体尸体上进行过研究,以确定在印度人群中是否有任何神经血管结构穿过 AIOF。这项人体研究将为临床医生提供更多信息,即相当多的患者可能有 AIOF,它们可能会传输神经血管结构,因此需要了解这方面的知识,以避免在手术和神经阻滞过程中出现意外并发症。
