aneurysmal bone cyst (abc) is an expansile bone lesion that usually involves the long bones. skull base involvement is rare. hereby, we describe a 17-year-old man with hoarseness, facial asymmetry, left sided sensorineural hearing loss and left jugular foramen syndrome. ct scan and mri showed a skull base mass that was confirmed as abc in histopathology. the case was unusual and interesting due...

The mandibular condyle region which protects the middle cranial fossa from facial and jaw traumas has an excellent osteomuscular structure. Condylar structures reduce or limit the force of trauma. Most importantly, the condylar neck is the weakest part of the mandible and is easily fractured without dislocation. Generally, this mechanism prevents condylar penetration into the middle cranial fos...

We examined the prenatal development of the human anterior cranial fossa and considered its clinical aspects. Our purpose was an evaluation of anterior cranial fossa geometry, its measurements and connections with the nasal cavity and middle cranial fossa. The study was performed on 29 foetuses from the first and second trimester of pregnancy. New methods of computer image analysis, Scion for W...

Rare Complication of Orthognathic Surgery: Intrusion Mandibular Condyle into the Middle Cranial Fossa

Cholesterol granuloma (CG) may erode into the middle ear, the mastoid bone and the petrous apex. However, aggressive erosion into the cranial cavity is extremely rare. Here we report a case of huge CG extending to the middle cranial fossa. Temporal bone computerized tomography showed a soft tissue mass which destroyed the bony plate of the posterior and middle cranial fossa. On magnetic resonan...

The intercondylar fossa (ICF) indices can be used to evaluate fossa geometry, which may in turn affect the function, pathology and intracapsular surgical repair of the cranial cruciate ligament. The measurements of digital images of the distal femur of 44 dogs were used to calculate the fossa width, shape, height and area indices. The mean values of fossa width index were found to be 0.19, 0.28...

In the present study, eight specimens of sheep (>1 year) of both sexes were dissected to provide a comprehensive description of the weight, allocation and nerve branches of the cranial cervical ganglion. The cranial cervical ganglion was found beneath the mandibular salivary gland. It was located ventromedial to tympanic bulla and ventrally to atlantic fossa. In three out of eight animals it wa...
