Ameloblastoma is a locally aggressive tumor derived from odontogenic epithelium. Although benign, its clinical behavior can often exhibit malignant characteristics. It is marked by slow and persistent growth with infiltration of adjacent tissues. Almost 70% occur in the mandible in patients older than 30 years. Recurrence of ameloblastoma from inadequate treatment is frequent. Because of its slow growth, recurrences can present decades after primary surgery. A primary ameloblastoma in an area outside the mandibular, maxillary, and infratemporal fossa regions has not been described in detail to date, with only 1 possible case mentioned in the literature...

Dentigerous or follicular cysts of odontogenic origin are innocuous benign cysts that are often linked with the crowns of permanent teeth. A dentigerous cyst circumventing permanent teeth fails to erupt and is often displaced into ectopic positions in the upper and lower jaw in the maxillofacial region. In the maxilla or upper jaw region, the impacted teeth are often displaced and/or shift into the maxillary sinus and apart from the nasal septum, mandibular condyle, coronoid process and the palate, to harbour such ectopic eruptions of teeth...

Gökhan Kuran, Demet Yazici
OBJECTIVE: Intracranial dermoid cysts are rare, slow-growing masses of sellar, parasellar regions, and posterior cranial fossa. The symptomatology of these cysts depends on the localization and presence of rupture. The preoperative diagnosis of these cysts by imagining techniques is distinctive as they have characteristic appearances. PATIENT: Endoscopic transnasal transpterygoid approach to infratemporal fossa for an extradural dermoid cyst of a 24 year-old woman is presented in this clinical report...

REVIEW
Gretchen M Oakley, Richard J Harvey
The endoscopic resection of pterygopalatine and infratemporal fossa malignancies allows excellent visualization and manipulation of tissues in an anatomically complex area compared with open approaches. With less approach morbidity, endoscopic endonasal surgery allows an easier recovery and earlier transition to adjuvant radiotherapy. The endoscopic approach is minimal access but rarely minimally invasive. Surgeons should not hesitate to gain wide surgical exposure of the pterygopalatine, infratemporal fossa, and petrocavernous carotid artery to ensure comfortable maneuverability and easy visualization of the tumor and its normal tissue margins...

BACKGROUND: Parapharyngeal space tumors (PPSTs) pose exposure challenges; they are routinely resected by the transcervical approach using blunt/blind finger dissection, increasing the risk of tumor spillage and of neurovascular injury. Large PPSTs or those located high at the skull base often require mandibulotomy or an infratemporal fossa approach, baring considerable morbidity. METHODS: The novel minimally invasive approach described, utilizes endoscopic equipment introduced transcervically for circumferential separation of the tumor from the neurovascular structures of the skull base...

First bite syndrome is a potential complication of surgery involving the infratemporal fossa, deep lobe of the parotid gland and parapharyngeal space. It is described as an acute and intense pain in the parotid region caused with the first bite of each meal. It is related to damage to sympathetic innervation of the parotid gland. Parasympathetic hyperactivation is believed to stimulate an exaggerated myoepithelial cell contraction causing pain. Usual analgesic treatments have poor results. Botulinum toxin type A causes parasympathetic nerve paralysis of the parotid gland and this fact would minimize salivation and decrease first bite syndrome...

A 19-year-old male presented with complaint of a bluish mass in the hard palate since 3 months. The patient had a history of trauma 8 years back in the left zygomatic area with a pen. It was lodged in the wound and removed at that time. Computed tomography scan was revealed a linear heterogenous dense structure extending from left infratemporal fossa to oral cavity, traversing through left maxillary sinus, with bone defect seen in lateral and medial wall of maxilla, and in the hard palate, most likely a neglected foreign body...

The zygoma, or jugum, is a cranial element that was present in Mesozoic tetrapods, well before the appearance of mammals. Although as an entity the zygoma is a primitive retention among mammals, it has assumed myriad configurations as this group diversified. As the zygoma is located at the intersection of the visual, respiratory, and masticatory apparatuses, it is potentially of great importance in systematic, phylogenetic, and functional studies focused on this region. For example, the facial component of the zygoma and its contribution to a postorbital bar (POB) appear to be relevant to the systematics of a number of mammalian subclades, and the formation of a bony postorbital septum (POS) that separates the orbit from the infratemporal fossa is unique to, and thus potentially phylogenetically significant for uniting anthropoid primates, while the zygoma itself appears to serve to resist tension and bending forces during mastication...

Synovial sarcoma is a soft tissue sarcoma especially encountered in the lower extremities. The infratemporal fossa is quite a rare location. Since it is a closed location, combined approaches and multidisciplinary planning always need to be considered. This case emphasizes the high-grade character of synovial sarcoma, which causes it to recur often. The difficulty of clear surgical margins in the infratemporal fossa adds to synovial sarcoma a second challenging issue. Therefore, the need of complementary therapy is essential...

We report a case of retiform hemangioendothelioma (RH) located in the infratemporal fossa and buccal area in a 13-year-old Korean boy. The tumor originated from the sphenoid bone of the infratemporal fossa area and spread into the cavernous sinus, orbital apex, and retro-nasal area with bone destruction of the pterygoid process. Tumor resection was conducted via Le Fort I osteotomy and partial maxillectomy to approach the infratemporal fossa and retro-nasal area. The diagnosis of RH was confirmed after surgery...

Infratemporal fossa injuries are uncommon and often go undetected presenting later with complications. We present a case of an infratemporal fossa penetrating injury with a ball point spring following a vehicular accident. Post-traumatic trismus even following supposedly trivial injury in the area should raise suspicion of possible injury in this location.
