Objective: To report a new therapeutic tactic for the old dislocation of intact mandibular condyle into the middle cranial fossa, which is extremely rare while the reported treatment methods are varied. Methods: The subject was a 29-year-old female who was diagnosed with old dislocation of intact left mandibular condyle into the middle cranial fossa and left zygomatic arch fracture. Gap arthrop...

usually located in the middle cranial fossa. Localizations in the posterior fossa are uncommon and generally remain asymptomatic or cause vague and non-specific symptoms. We describe the unusual case of a patient with an AC suffering from recurrent polymorphic vertigo with atypical nistagmus and transient sensorineural hearing loss. The clinical-diagnostic features are discussed, etiopathogenic...

arachnoid cysts are congenital lesions arising from the arachnoid membrane. the incidence of arachnoid cysts in the general population is around 0.1% and their most common location is the middle fossa. arachnoid cysts usually present during the childhood and are identified incidentally. when symptomatic, the most common presentations include headache and seizure. the popular treatment for this ...

A retrospective review was performed of patients treated for middle ear cholesteatoma with bone defects of the skull base via a combined transmastoid/middle fossa approach at the University of Tsukuba Hospital from 2006 through 2011 to determine the safety and effectiveness of a combined transmastoid/middle fossa approach for the treatment of cholesteatoma involving the middle cranial fossa. Th...

The Anterior Clinoid Processe (ACP) and Middle Clinoid Process (MCP) are sometimes connected by an osseous bridge formed by ossification of Carotico-clinoid Ligament (CCL), converting the distal end of carotid sulcus into an ostium called the Carotico-clinoid Foramen (CCF). Through the CCF passes one of the segment of Internal Carotid Artery (ICA). The CCF is the result of ossification of eithe...

A rare case of synovial chondromatosis with extension to the middle cranial fossa is reported. Synovial chondromatosis, a benign disorder characterized by multiple cartilaginous, free-floating nodules that originate from the synovial membrane is not exclusive to the temporomandibular joint (TMJ). This condition is commonly seen in the axial skeleton and can involve multiple joints. In this case...

A case is reported of a 7 year-old girl who suffered a central luxation of the mandibular condyle into the middle cranial fossa. The management and previously reported cases are discussed.

OBJECTIVES/HYPOTHESIS Image-guided optical tracking systems are being used with increased frequency in lateral skull base surgery. Recently, electromagnetic tracking systems have become available for use in this region. However, the clinical accuracy of the electromagnetic tracking system has not been examined in lateral skull base surgery. This study evaluates the accuracy of electromagnetic n...
