Abstract

PURPOSE

Various studies have been conducted on morphometric variations of infraorbital foramen to provide data to surgeons for nerve block in infraorbital region. This study aims to analyse the anatomical variations by comparing various morphometric measurements of infraorbital foramen in dry skulls of adult North Indian population. This study becomes relevant in the present study group as very scant data is available about the variations and morphometric measurements in Indian population. The data thus collected can be standardized and become useful for the surgeons working in this area of face.

MATERIALS AND METHODS

The study was conducted on 75 dry adult human skulls, which were a part of Department of Anatomy, used for teaching purposes in medical colleges. Straight distance of the Infraorbital foramen from the infraorbital rim, supraorbital foramen and sagittal plane was measured. The position of the infraorbital foramen was determined in relation to maxillary teeth and supraorbital foramen. The data thus obtained was analysed.

RESULTS

The distance of infraorbital foramen from infraorbital rim, supraorbital foramen, sagittal plane in the present study was found to be 6.71 ± 1.11 mm, 42.02 ± 4.31 mm and 31.94 ± 4.88 mm respectively. The position of infraorbital foramen was lateral in relation to supraorbital foramen (in 88% of cases). Infraorbital foramen was above the 1st premolar tooth in most of the cases. Accessory infraorbital foramen was found in 11.2% cases (double foramen).

CONCLUSION

The data thus obtained will perhaps be helpful to the surgeons in identifying the extent of the operative field thereby reducing procedural risks.

摘要

目的

已针对眶下孔的形态计量学变异开展了多项研究,以便为外科医生提供眶下区域神经阻滞的数据。本研究旨在通过比较成年北印度人群干燥颅骨中眶下孔的各种形态计量学测量值来分析解剖变异。由于关于印度人群变异和形态计量学测量的数据非常稀少,本研究在当前研究组中具有相关性。如此收集的数据可以标准化,并对从事面部该区域工作的外科医生有用。

材料与方法

本研究对75个成年人类干燥颅骨进行,这些颅骨是解剖学系的一部分,用于医学院的教学目的。测量了眶下孔到眶下缘、眶上孔和矢状面的直线距离。确定了眶下孔相对于上颌牙齿和眶上孔的位置。对由此获得的数据进行了分析。

结果

在本研究中,眶下孔到眶下缘、眶上孔、矢状面的距离分别为6.71±1.11毫米、42.02±4.31毫米和31.94±4.88毫米。眶下孔相对于眶上孔位于外侧(88%的病例)。在大多数病例中,眶下孔位于第一前磨牙上方。在11.2%的病例中发现了副眶下孔(双孔)。

结论

如此获得的数据可能有助于外科医生确定手术区域的范围,从而降低手术风险。
