introduction: ondine’s curse is a catastrophic but rare condition in adults. it is referred to as a congenital or acquired condition, in which the patient cannot breathe automatically while asleep. acquired causes of this disease can be any cause affecting the ventrolateral part of the medulla, which is considered to be the breathing center in humans.    case report:   a 51-year-old woman, with...

Objectives We report our institutional experience with calcifying pseudoneoplasms of the skull base that presented with cranial neuropathies. These lesions are also known as fibro-osseous lesions, cerebral calculi, or brain stones. Results One patient presented with facial numbness and retro-orbital pain secondary to compression of the maxillary branch of the trigeminal nerve at the anterior po...

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...

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...

The trigeminal cave (TC) is a special channel of dura mater, which extends from the posterior cranial fossa into the posteromedial portion of the middle cranial fossa at the skull base. The TC contains the motor and sensory roots of the trigeminal nerve, the trigeminal ganglion (TG) as well as the trigeminal cistern. This study aimed to review the anatomy of the TC and TG and determine some par...

In recent years, neonatal cranial sonography has been extensively used to diagnose intracranial hemorrhages, congenital anomalies, and intracranial masses despite such limiting factors as the size of the anterior fontanelle and lack of contrast enhancement similar to cranial CT [1] . While cranial CT during infancy lacks easy access to direct sagittal scanning, sonography offers multiplanar ima...

A 7-year-old boy underwent resection of a posterior fossa medulloblastoma. Two days later, he developed facial diplegia, left abducens nerve palsy, and mild hypalgesia below the neck. MRI documented 2 dot-like ischemic foci in the pons (figure). We diagnosed the unusual bilateral occurrence of Gasperini syndrome, a lesion of the sixth and seventh cranial nerve nuclei and the lateral spinothalam...

UNLABELLED The classic approach for cochlear implant surgery includes mastoidectomy and posterior tympanotomy. The middle cranial fossa approach is a proven alternative, but it has been used only sporadically and inconsistently in cochlear implantation. OBJECTIVE To describe a new approach to expose the basal turn of the cochlea in cochlear implant surgery through the middle cranial fossa. ...
