Modifications to the orbitozygomatic approach. Technical note.
The orbitozygomatic craniotomy is one of the workhorse approaches of skull base surgery, providing wide, multidirectional access to the anterior and middle cranial fossae as well as the basilar apex. Complete removal of the orbitozygomatic bar increases the angles of exposure, decreases the working depth of the surgical field, and minimizes brain retraction. In many cases, however, only a porti...
متن کاملOrbitozygomatic approach to basilar apex aneurysms.
Basilar apex region aneurysms are among the most complex cerebral aneurysms. They are not, however, among the most common aneurysms, and increased use of endovascular treatment has further decreased the number of patients with these lesions who undergo surgery. Nonetheless, not all basilar apex aneurysms are amenable to coil embolization, and neurosurgeons must be prepared to treat patients wit...
متن کاملIsolated relative afferent pupillary defect secondary to contralateral midbrain compression.
BACKGROUND Relative afferent pupillary defects are typically related to ipsilateral lesions within the anterior visual pathways. OBJECTIVE To describe a patient who had a workup for headache and was found to have an isolated left relative afferent pupillary defect without any other neurological findings. DESIGN We review the neuroanatomy of the pupillary light reflex pathway and emphasize t...
متن کاملIsolated superior rectus palsy due to contralateral midbrain infarction.
BACKGROUND Isolated superior rectus palsy due to a contralateral midbrain lesion has not been reported. CASE DESCRIPTION A 71-year-old woman suddenly developed diplopia. Examination showed that she had isolated superior rectus paresis. Magnetic resonance imaging showed a tiny infarct at the area of the oculomotor nucleus on the contralateral side. CONCLUSION Isolated superior rectus palsy m...
متن کاملDecompressive craniectomy: contralateral lesions and metabolic abnormalities.
OBJECTIVE To define the incidence of new contralateral intracranial lesions following decompressive hemicraniectomy for blunt traumatic brain injury, and explore the potential association with metabolic factors that contribute to coagulopathy. METHODS We retrospectively reviewed the records and imaging of all patients treated with hemicraniectomy for blunt traumatic brain injury at our instit...
