What is orbitozygomatic craniotomy?
What is orbitozygomatic craniotomy?
The orbitozygomatic craniotomy (OZ) involves an expansion of the pterional approach through osteotomy of various sections of the superior/lateral orbital rim/roof and zygoma. These modified variations involve mobilization of the orbital roof and rim as well the frontal process of zygoma.
What is pterional craniotomy?
The pterional or frontotemporalsphenoidal craniotomy is an extensively used neurosurgical technique to expose the Sylvian fissure (SF). The pterional approach (PA) is performed around the pterion, which represents the intersection of the frontal, temporal, parietal, and sphenoid bones.
Why do people get craniotomy?
A craniotomy may be done for a variety of reasons, including, but not limited to, the following: Diagnosing, removing, or treating brain tumors. Clipping or repairing of an aneurysm. Removing blood or blood clots from a leaking blood vessel.
What is supratentorial craniotomy?
Supratentorial craniotomy means the exposure of any part of a cerebral hemisphere over the basal line joining the nasion to the inion.
How long is a craniectomy?
Depending on the underlying problem being treated, the surgery can take 3 to 5 hours or longer. You will lie on the operating table and be given general anesthesia.
What causes craniotomy?
Reasons for the procedure A craniotomy may be done for a variety of reasons, including, but not limited to, the following: Diagnosing, removing, or treating brain tumors. Clipping or repairing of an aneurysm. Removing blood or blood clots from a leaking blood vessel.
What is orbitozygomatic craniotomy (Oz)?
The orbitozygomatic craniotomy (OZ) involves an expansion of the pterional approach through osteotomy of various sections of the superior/lateral orbital rim/roof and zygoma.
What are orbitozygomatic approaches to osteotomy?
Currently, orbitozygomatic approaches comprise a group of surgical approaches to the skull base that suggest involvement of elements of the orbital wall s (superior and lateral) and zygomatic bone into the bone block formed during osteotomy.
Is the 3-piece orbitozygomatic approach in neurosurgery effective?
CONCLUSION: The modifications described herein show the technical features of the 3-piece orbitozygomatic approach, which provides excellent brain exposure with less retraction and a good cosmetic result. The pterional approach (frontotemporosphenoidal approach) 1-4 is one of the most common approaches in neurosurgery.
What is the orbitozygomatic approach to cranial fossa?
The orbitozygomatic approach provides wide, multidirectional access to the anterior and middle cranial fossa e, as well as to the upper third of the posterior fossa and clivus.
