this case report presents an eight-year-old girl having periauricular swelling and severe pain during mouth opening on the right-side temporomandibular joint (tmj). cbct showed extensive destruction of the base of the skull and the roof of the glenoid fossa on the right side. the findings based on ct and mri images with and without contrast are discussed herein. this report highlights a skull b...

The skull base is one of the most complex anatomical regions and forms the floor of the cranial cavity. Skull base surgery involves open, microscopic, and endoscopic approaches to the anterior, middle, or posterior cranial fossa. A multispecialty team approach is essential in treating patients with skull base lesions. Traditionally, rhinologists are involved in providing access to anterior skul...

Introduction: Skull-based osteomyelitis is bony infection which generally originates from inadequately treated chronic infection, adjoining tissue infection or after trauma.Case: 11 month female child had a trivial fall while standing near a bucket. The child developed fracture of right clavicle and left orbital swelling which was inadequately treated. This resulted in in spread of infection to...

OBJECTIVES/HYPOTHESIS Several techniques of endoscopic repair of cerebrospinal fluid (CSF) rhinorrhea were prescribed. Defect localization was mandatory for all. STUDY DESIGN Prospective study. METHODS A prospective study was conducted on nonaccidental CSF rhinorrhea. The sensitivity and specificity of image-guided navigation in localizing the defect were studied. The feasibility and reliab...

Reconstruction of small dural defects is independent of which technique is used, and vascularized tissue does not appear to be critical. In contrast, large dural defects have been traditionally repaired using regional vascularized flaps, as they promote healing and diminish complications. Recently, novel regional vascularized flaps that do not require cutaneous incisions have been designed: nas...

Traumatic chiasmal syndrome is one of the rare etiologies syndrome, characterized by optic chiasm injury following head trauma. The main visual defect associated bitemporal hemianopia with macular splitting; however, it can present a variety other defects and neurologic signs. authors report case complete after trauma, multiple frontal skull base fractures no deficits, or hypothalamic-pituitary...

BACKGROUND AND PURPOSE Endoscopic endonasal approach is the procedure of choice for the resection of ventral skull base neoplasms, with defect closure requiring multilayer reconstruction. This study evaluates the temporal MR imaging evolution of nasoseptal flaps and free grafts used in endoscopic skull base reconstruction. MATERIALS AND METHODS Sixty-nine follow-up brain MRIs of 22 patients w...

INTRODUCTION The infraorbital nerve represents the largest cutaneous branch of the maxillary nerve to supply the area of skin derived from the embryonic maxillary prominence. It emerges from the infraorbital foramen on a line that runs almost vertically through the pupil to supply sensation to the cutaneous surfaces of the lateral aspect of the nose, upper lip, and lower eyelid. It is important...
