“…Access to the infratemporal fossa has been studied by a number of authors, assessing both clinical and anatomical scenarios, with a variety of modifications proposed for each approach. [15][16][17][18][19][20][21] Two major routes of access to the infratemporal fossa have been described: the lateral and the anterior approach. 3,[22][23][24] The lateral approach adds great complexity to the procedure as it generally involves resection of the parotid gland (and related facial nerve dissection), or dissection or resection of the temporalis muscle and its related attachment (the mandibular condyle).…”

“…There are several important structures related to PPFRS surgery, which include the nerves of the infraorbital, pterygoid canal, greater palatine and internal maxillary artery and its branches, as well as the foramen rotundum, ovale and spinosum [12,13]. In the present study, we focused on observing and measuring the spatial locations of landmarks related to the above structures.…”

Background: The spatial orientation rules of the important skull base structures are essential for performing endoscopic surgery. However, there is no satisfactory three-dimensional (3-D) anatomy study available to the surgeon at present. The aims of this study are to construct a new method to learn the spatial orientation of anatomical features under endoscopy and to help the surgeon establish a 3-D image of skull base structures in his mind. Methods: A modified MicronTracker navigation system was used to measure the pitch angle, direction angle and distance from the reference points to various anatomical landmarks of the pterygopalatine fossa and related structures (PPFRS) at the skull base in 10 fresh cadavers (20 sides). Results: The location data of the positions of the major landmarks were acquired and a digital model of the anatomical structures of the PPFRS was built, which can be moved, whirled or demonstrated easily. Conclusion: It is practical to measure the positions of the anatomical structures of the PPFRS with a modified binocular vision-based MicronTracker navigation system. It is a valuable exploration tool to help the surgeon establish the orientation of surgical landmarks in his mind by the 3-D parameters and model.

“…18 A recent endoscopic, transantral study of the infratemporal fossa examined the foramen rotundum, foramen ovale and foramen spinosum, and also identified the maxillary and mandibular nerves and the middle meningeal artery. 19 Both lateral and anterior external infratemporal fossa approaches may have complications, including facial nerve dysfunction, fascial deformities, inferior orbital nerve dysfunction, dental malocclusion and lacrimal dysfunction. 8 In 1996, Robinson et al described a two-surgeon, transnasal approach for managing tumours extending into the infratemporal fossa.…”

This endoscopic two-surgeon technique is an excellent approach for managing angiofibroma extending to the pterygopalatine and infratemporal fossae. Our modification markedly decreased morbidity by avoiding septum opening and sublabial incision, and by enabling better haemostasis (via maxillary artery control). Recurrence may be minimised by careful examination of the lateral sphenoid wall, pterygoid canal and infratemporal fossa pterygoid muscles.

Endoscopic transnasal study of the infratemporal fossa: A new orientation

Abstract: The current study provides a novel endoscopic orientation to the medial ITF. Such knowledge should provide an anatomical basis for experienced surgeons to endoscopically address this region with more safety and efficacy.
