The foramen ovale of the sphenoid bone is often cannulated for the treatment of trigeminal neuralgia. The success of foramen ovale cannulation procedures depends upon the properly locating the foramen, most often via fluoroscopy. Miscannulation may result in severe adverse events including intracranial hemorrhage and death. Unfortunately, despite fluoroscopic guidance, miscannulations continue to occur. Therefore, study of the location of the foramen ovale relative to anatomical landmarks that are easily identifiable through fluoroscopy is warranted. This study assessed the location of the foramen ovale in 228 crania. Three lines drawn upon digital photographs were assessed with regard to whether or not they traversed the foramen ovale. The lines included 1) a sagittal line drawn through the posterior‐most molar; 2) a line drawn through both the posterior‐most molar and the lateral‐most aspect of the ipsilateral occipital condyle; and 3) a transverse line drawn between the articular eminences. Of all the lines, the transverse line most consistently traversed the foramen ovale, bilaterally (left side: 159:228, 69.7%; right side: 157:228, 68.9%; bilateral: 316:456, 69.3%). Likewise, sagittal lines traversed the foramen more often than not. Because the articular eminence is easily identifiable via fluoroscopy from a lateral projection, the results of this study suggest that the articular eminence, in particular, may be a useful landmark for the cannulation of the foramen ovale. Moreover, using the articular eminence in conjunction with the molars and occipital condyles may improve localization of the foramen ovale from both lateral and AP views.
