Mucormycosis is a life-threatening infection affecting patients with diabetes. It is an angioinvasive disease often resistant to treatment with a debilitating course and high mortality. Here, we report a case of a 45 year old woman with type 2 diabetes mellitus who presented to us with history of right-sided ptosis and facial palsy, and subsequently developed loss of vision and palatal palsy. She was in diabetic ketoacidosis. Nervous system examination revealed involvement of right second, third, fourth, sixth, seventh, ninth, and tenth cranial nerves, suggestive of Garcin syndrome...

Juvenile nasopharyngeal angiofibroma is a locally aggressive benign tumour which has propensity to erode the skull base. The tumour spreads along the pathways of least resistance and is in close proximity to the extracranial part of trigeminal nerve. Advancements in expanded approaches for endoscopic excision of tumours in infratemporal fossa and pterygopalatine fossa increase the vulnerability for the trigeminocardiac reflex. The manipulation of nerve and its branches during tumour dissection can lead to sensory stimulation and thus inciting the reflex...

War injuries are the cornerstone of maxillofacial surgery, and it led to the initiation and development of this specialty, and each case represents a challenge to the surgeon who deals with it. In this article, we present a 30-year-old male patient who was referred to our emergency department complaining of gunshot wound, severe pain, and limitation in mouth opening. Preoperative imaging showed a bullet with a very long path lodged in the infratemporal fossa. Three different approaches with the aid of C-arm imaging system were used for the removal of this bullet; the last approach was the successful one...

INTRODUCTION: Access osteotomies provide direct exposure to inaccessible areas of the deep part of craniofacial skeleton for treating pathologies involving vital structures. The use of maxillary swing approach for gaining wide access to the nasopharynx, infratemporal fossa, parapharyngeal space, middle fossa of skull base. Though the maxillary swing requires transfacial incision for wide exposure but with careful handling the scar is minimum and this approach can be used in young people...

The extranasopharyngeal angiofibroma is a separate clinical entity but those involving infratemporal fossa and cheek resemble juvenile nasopharyngeal angiofibroma (JNA) and hence have been labelled as juvenile perinasal angiofibroma (JPA) in this paper. This paper presents a 7th case of JPA and attempts to review the world literature on JPA, along with a proposal of staging the disease. A 16 year male presented with a painless compressible facial swelling since 7 months without any epistaxis or nasal obstruction...

Neoplasms located in the parotid region, temporal bone, infratemporal fossa, and lateral skull base represent a challenge due to their difficult anatomic location and surrounding neurovascular structures. A variety of surgical approaches are appropriate to access this area, although several of them can place the auricular blood supply in danger. If the auricular blood supply is compromised, ischemia and, eventually, avascular necrosis of the auricle can occur. Auricular necrosis often can cause patients a delay in adjuvant radiation therapy and result in the need for additional reconstructive procedures...

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...

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...
