o bjectives: pneumatized articular eminence or tubercle (pat) is an air cell cavity in the zygomatic process of the temporal bone. pneumatization of articular eminence may be seen incidentally on panoramic radiographs (pr) as a unilocular or multilocular, radiolucent defect. the aim of this study was to assess the prevalence and the pattern of pat on pr in an iranian population. materials and m...

introduction: osteomas are asymptomatic and rare slow growing bony tumors in temporal bone, and should be taken into account in differential diagnosis of the osteolytic solitary skull lesions. sometimes is associated with pain and functional loss. only a few cases have been reported.   case report: we describe a case of an osteoid osteoma of the temporal bone (mastoid) in a 31-year-old woman pr...

in this research, anatomical descriptions of the structure of the temporal bone and auditory ossicles have been performed based on dissection of ten guinea pigs. the results showed that, in guinea pig temporal bone was similar to other animals and had three parts; squamous, tympanic and petrous .the tympanic part was much better developed and consisted of oval shaped tympanic bulla with many re...

case presentation here, we report the case of a 35-year-old man complaining of bilateral incomplete eye closure, two weeks after a closed head injury caused by a motor vehicle accident. introduction although bilateral facial nerve palsy is a rare condition, its etiology is more detectable than the unilateral type. a temporal bone fracture is one cause of bilateral facial nerve palsy, contributi...

conclusions in surgery for facial nerve neuroma in the mastoid segment, it is better not to rely on imaging alone; all facial nerves from the geniculate ganglion to the styloid foramen become exposed for tumor removal. case presentation in this report, we describe a rare facial nerve neuroma in the mastoid portion in a 55-year-old man with a history of hypertension (htn) and diabetes mellitus (...

Introduction: Temporal bone osteomyelitis is more commonly seen in immunocompromised patients and is very rare in non-immunocompromised individuals. Mucormycosis is a fulminating fungal infection caused by Mucor which is a saprophytic fungus commonly seen in diabetic patients. Here we report a case of temporal bone osteomyelitis in a child with a traumatic history which was causing clinical fe...

Introduction: Metastatic tumors of the temporal bone are extremely rare. Collet-Sicard syndrome is an uncommon condition characterized by unilateral palsy of the lower four cranial nerves. The clinical features of temporal bone metastasis are nonspecific and mimic infections such as chronic otitis media and mastoiditis.   Case Report: This report describes a rare case of metastatic adenocarcino...

background many clinical and experimental studies have been done to analyze the anatomical and functional aspects of the internal auditory canal (iac) in human beings since there are great inter-individual variability and structural variations that may occur regarding the other adjacent structures. objectives the purpose of this study was to characterize the morphology of the internal auditory ...

introduction: ewing’s sarcoma is the second most common primary malignant tumor of bone found in children after osteosarcoma. it accounts for 4–9% of primary malignant bone tumors and it affects bones of the skull or face in only 1–4% of cases. hence it rarely affects the head and neck. subject and method: in this case report, we describe a case of primary ewing's sarcoma occurring in the tempo...

conclusions our study shows in terms of figures that measurements of features of the temporal bone made from spiral ct scan images and those directly obtained during surgery are similar to an adequate extent. results twenty cases were included. in the three measurements performed in this study, only the first parameter (distance between the canal and the sigmoid sinus) was significantly differe...
