High‐resolution computed tomography analysis of the medial infratemporal fossa: a pilot study

Abstract

Average distance from the ANS to the AFO and BB was 78.5 mm and 83.2 mm, respectively. These measurements can be used by endoscopic skull base surgeons to guide dissection in the ITF.

Endonasal, transmaxillary, transpterygoid approach to the foramen ovale: radio-anatomical study of surgical feasibility

“…mean ± SD of 80.3 ± 4.3 mm in males and 77.0 ± 6.5 mm in females) were comparable to our own findings (i.e. 80.2 ± 3.4 mm on the left and 80.4 ± 3.5 mm on the right in men; and 74.0 ± 3.1 mm on the left and 74.1 ± 2.9 mm on the right in women) 30 . However, Eloy et al did not find a statistically significant difference between the sexes regarding these measurements, whereas we found a clear sex difference for two of our four foramen ovale landmark measurements (i.e.…”

“…distances from the posterior maxillary wall and from the anterior nasal spine). 30 This difference is unlikely to be explained by any sex difference in the shape of the foramen ovale itself. Ray et al examined the foramen ovale morphology and found no statistically significant differences between men and women, regarding size or shape.…”

“…Eloy and colleagues' assessment of the anatomy of the infratemporal fossa examined CT data for only 15 patients. 30 In contrast, we examined CT data for 109 patients, including both left and right sides. In addition, almost all these previous authors stated that there were no statistically significant differences for the landmarks they assessed.…”

“…The anatomical studies undertaken by Theodosopoulos et al 4 Herzhallah et al 20 and Cai et al 29 only examined 4, 5 and 11 cadaveric heads, respectively, regarding the endoscopic approach to the infratemporal fossa. Eloy and colleagues' assessment of the anatomy of the infratemporal fossa examined CT data for only 15 patients 30 . In contrast, we examined CT data for 109 patients, including both left and right sides.…”

Comprehensive review on rhino-neurosurgery

“…The distance of the foramen ovale to the anterior nasal spine amounts to around 8 cm. Beside the lateral process, the buccal nerve may serve as guideline for identifying the foramen ovale [ 36 ], [ 146 ], [ 257 ], [ 263 ], [ 264 ], [ 265 ], [ 266 ], [ 267 ], [ 268 ]. Dorsal of the foramen ovale, the internal carotid artery is found in a distance of about 5 mm in the middle part of its petrosal segment [ 269 ].…”
