“…In the case of trigeminal neuralgia, the most commonly affected nerve division is the mandibular nerve, with the ophthalmic division being the least affected ( 11 ). In 20% of cases, mandibular neuralgia is caused due to compression by abnormal bony outgrowths at the skull base ( 12 ). The mandibular nerve passes through the foramen ovale into the infratemporal fossa and its branches supply the derivatives of the first pharyngeal arch.…”

Background: Restricted access and compression of neurovascular structures at various anatomic variations at the skull base poses a challenge to surgeons, neurologists and anesthetists. The present study was performed with the objective of providing morphometric analysis of innominate foramina, and anomalous bony bars and spurs along the infratemporal surface of the greater wing of the sphenoid and reviewing the practical significance of dealing with this region. Methods: A total of 100 dry-aged human adult skulls from the archives of the osteology library of the Department of Anatomy were studied. A detailed morphometric analysis of such innominate foramina and anomalous osseous structures along the base of the sphenoid was performed using a sliding digital vernier caliper. Results: Anomalous bony bar was found in 22 skulls (25.28%). A complete bar was observed at eight (9.1%). An innominate foramen was located inferomedial to foramen ovale (5 unilateral and 3 bilateral) with a mean anteroposterior diameter of 3.44 mm and a mean transverse diameter of 3.16 mm. Conclusion: Neurovascular structures may be compressed by abnormal bony outgrowths or while traversing through such unnamed bony foramina. The latter may also be overlooked and mistaken during radiological interpretation leading to delayed diagnosis. Such unnamed foramina and bony outgrowths need to be documented in the literature due to their surgical, and radiological implications and limited citations.

“…However, Ghai et al, 20 observed complete bilateral ossified PSBs in only one out of 50 skulls. von Ludinghansen et al, 11 in their study on 100 Japanese skulls and 54 German cadavers noticed completely ossified PSL in 6% of skulls and 1.85% of cadavers, PSL in 20.4% of cases, pterygospinous muscle in 9.2% of cases.…”

“…40 Anatomical knowledge of these bony bars is beneficial for anesthetics, dental and maxillofacial surgeons during the treatment of neuralgia. 20 Furthermore, the foramen ovale may be obliterated by these ligaments resulting in mandibular neuralgia. 41 In those patients where other causes of compressive syndrome cannot be diagnosed, compression of the regional structures like nerves by these bony bars should be considered.…”

Resumen: El ligamento Pterigoespinoso (LP) se extiende desde el proceso Pterigoespinoso de la placa Pterigoideo lateral a la espina etmoidal del hueso esfenoides. A veces, se puede osificar formando un puente de hueso que une el foramen espinoso con el cual el nervio mandibular y sus ramas están relacionados de manera variable. Los nervios mandibulares y el cordón timpánico se pueden comprimir resultando en diversos síntomas clínicos, que a su vez dependen de las dimensiones del foramen y los grados de compresión. Por lo tanto, el conocimiento de la posición y el grado de osificación del ligamento pterigoespinoso y su relación con las estructuras importantes en la fosa infratemporal profunda es importante para radiólogos, neurólogos, cirujanos maxilofaciales, cirujanos dentales y anestesistas durante diversos procedimientos anestésicos y quirúrgicos.
