Endoscopic and three-dimensional radiographic imaging of the pterygopalatine and infratemporal fossae: improving surgical landmarks.
7
TL;DR: The pterygoid ridge is a novel and reliable osseous landmark that could assist surgeons during endoscopic surgery on the PPF and ITF through endoscopic cadaver dissections and radiographic imaging analysis.

Abstract: Objectives:We sought to define the surgical endoscopic anatomy of the pterygopalatine fossa (PPF) and infratemporal fossa (ITF) through endoscopic cadaver dissections and radiographic imaging analysis.Methods:Eleven fresh cadavers were submitted to computed tomography (CT) and endoscopic dissection. We used 3-dimensional (3-D) CT reconstruction and endoscopic video imaging for analysis of the bony and soft tissue landmarks. One fixed cadaver head was grossly dissected to confirm the endoscopic anatomic findings.Results:The CT and 3-D CT reconstruction measurements between the pterygoid canal and the foramen rotundum averaged 4.36 mm and 5.09 mm, respectively. An osseous ridge (pterygoid ridge) was identified on the anterior face of the pterygoid process as a novel identifiable anatomic landmark in all of the specimens. The average length of the pterygoid ridge on 3-D CT reconstruction was 7.84 mm. The internal maxillary artery entered the PPF posteromedial to the temporalis tendon and anterolateral to the...

Gülay Açar,Aynur Emine Cicekcibasi,İbrahim Çukurova,Kemal Emre Özen,Muzaffer Şeker,Ibrahim Guler +5 more
TL;DR: Preoperative radiologic analysis of the vidian canal and the surrounding structures will allow surgeons to choose an appropriate endoscopic approach to ensure predictable postoperative outcomes.
Excision of recurrent synovial sarcoma of the infratemporal fossa.
TL;DR: A 68-year-old male patient together with totally excised synovial sarcoma in the infratemporal fossa is presented by mandibular swing and transzygomatic technique information on the manifestation, imaging, histopathological features and postoperative complications of previous infratm temporal fossa synovIAL sarcomas.

Carl‐Peter Cornelius,Peter J.J. Gooris +1 more
- 01 Jan 2023
TL;DR: The bony anatomy of the orbit is characterized by a distinctive quadrangular pyramidal shape and intricate network of fissures, canals, grooves, foramina, and notches. The sphenoid serves as the backward foundation and starting point for the overall architectural composition. Recent publications emphasize the utilization of imaging techniques for detailed morphometric evaluation and quantification.
Endoscopic endonasal bony landmarks of vertical petrous internal carotid: anatomic study
Sameh M Amin,Hesham Fathy +1 more
TL;DR: The proposed endonasal bony pathway relatively bypasses the muscular compartment of infratemporal fossa and can help to obtain vascular control of basal ICA and retrograde identification of parapharyngeal ICA.
Morphometric analysis of vidian canal and its relations with surrounding anatomic structures by using cone-beam computed tomography.
TL;DR: Anatomic characteristics of the VC on CBCT images unique to Turkish populations should be kept in mind during surgery.

TL;DR: Endoscopic skull base surgery has undergone rapid advancement in the past decade moving from pituitary surgery to suprasellar lesions and now to a myriad of lesions extending from the cribriform plate to C2 and laterally out to the infratemporal fossa and petrous apex.

Anatomic variations of sphenopalatine artery and minimally invasive surgical cauterization procedure.
TL;DR: The ramification pattern of SPA can not be fully exposed without resection of the posterior part of the middle turbinate via the middle meatal approach and a minimally invasive surgical cauterization procedure is defined based on the variations of Spa and SPF.

TL;DR: Entering the PPF inferior to the horizontal plane of the SPF along a vertical line drawn inferiorly from the infraorbital canal will avoid injury to the major neural structures in the fossa.

Relationship of the maxillary artery and lateral pterygoid muscle in a caucasian sample
TL;DR: This study shows that the lateral or superficial course of the maxillary artery relative to the lower head of the lateral pterygoid muscle is more prevalent than the medial or deep course.
