Echinococcosis is a parasitic infection also called as hydatid disease or hydatidosis. Hydatidosis is a cyclo-zoonotic infection of the larvae form of Echinococcus granulosus (canine tapeworm). The majority of hydatid cysts are seen in the liver (65%) as most of the embryos are trapped within it. Infratemporal region is an unusual site for hydatidosis and has been sparsely reported in the literature. To the best of our knowledge, this is the fourth and perhaps the largest case report of hydatidosis involving the mandible in the literature in right infratemporal region involving the ramus condyle unit in a 35-year-old female with chief complaint of pain on right side of temporomandibular joint area on mastication, and opening and closing of mouth.

With their close anatomical relationship, the temporomandibular joint (TMJ), mandibular ramus, skull base, ear, and infratemporal fossa make up a complex structure that may collectively be referred to as the 'TMJ and adjacent structures complex' (TASC). This study presents the neoplasms that may be encountered in the TASC region and their classification, which may be useful for the surgical treatment. Data of 1022 consecutive patients treated with resection of TASC neoplasms from May 2000 to October 2022 were reviewed.

However, cases invading the pterygopalatine fossa are extremely rare. In this article, we describe a rare case of a man in his early 60s who presented with left nasal congestion, headache, epistaxis, and facial numbness.

Background: The posterior maxilla and skull base is a region with a complex anatomy. Accurate resection of the pterygoid plate is critical during a maxillectomy procedure. However, there is a paucity of functional and anatomical studies on the pterygoid plate and skull base.

Surgical access to tumors involving the infratemporal fossa (ITF) and adjacent regions can be challenging, and there is a continued need for novel approaches to complex tumors in this region. In this manuscript, we present a unique anatomical approach that allows contiguous exposure of the ITF and buccal space with mobilization of the lateral maxillary buttress. Laryngoscope, 2024.

Objectives: The parapharyngeal space (PPS) and infratemporal fossa (ITF) present significant challenges for endoscopic skull base surgery due to their complex anatomy and lack of clear bony landmarks. This study aims to propose a systematic compartmentalization of the PPS and ITF, based on key anatomical structures, to optimize surgical planning and approaches.
Methods: To retain a precise bony reference framework, the walls of the maxillary sinus and pterygoid bone were preserved.
