The foramen ovale (FO) is present in the posterior part of the greater wing of sphenoid. A trauma or space-occupying lesion in this area would result in clinical manifestations due to compression of the structures passing through it. This study was undertaken because of the clinical significance of the FO in radiological and neurological procedures. The aim is to study the morphometry of the FO and its bilateral variations.
Fifty adult dry human skulls of unknown age and sex were studied. The shape of the FO, presence of accessory foramina or abnormal bony outgrowths, if any, were noted. Maximum length and width of FO were measured.
The FO was present bilaterally in all 50 skulls. Accessory foramen was present in 17 (34%) and 13 (26%) skulls on the right and left side, respectively. Bony out growths were present in 9 (18%) and 15 (30%) skulls on the right and the left side, respectively.
Understanding the exact topography, morphometry and variations of the FO is required to enable the clinician to correctly interpret radiographs and help in planning the surgical procedures. The findings presented here should be taken into account when neurological procedures of the middle cranial fossa are performed.
卵圆孔位于蝶骨大翼后部。该区域的创伤或占位性病变会因穿过其中的结构受压而导致临床表现。由于卵圆孔在放射学和神经学检查中的临床意义，开展了本研究。目的是研究卵圆孔的形态测量及其双侧变异情况。
研究了50个年龄和性别未知的成人干燥人类颅骨。记录卵圆孔的形状、是否存在副孔或异常骨赘。测量卵圆孔的最大长度和宽度。
50个颅骨双侧均有卵圆孔。右侧和左侧颅骨分别有17个（34%）和13个（26%）存在副孔。右侧和左侧颅骨分别有9个（18%）和15个（30%）存在骨赘。
临床医生需要了解卵圆孔的确切局部解剖、形态测量和变异情况，以便正确解读X线片并有助于手术方案的制定。在进行中颅窝神经手术时应考虑此处给出的研究结果。
