Restrictive Strabismus Following Frontotemporal-orbitozygomatic Craniotomy
نویسندگان
چکیده
The frontotempotal-orbitozygomatic craniotomy (FTOZ) is a standard approach for large sphenoid wing meningiomas (SWMs). Nevertheless, resection of these tumors is not without ophthalmologic risks. This series presents two patients with acute postoperative restrictive strabismus following tumor resection and orbital wall reconstruction. Forced duction testing and postoperative imaging revealed impingement of the lateral rectus muscle caused by an alloplastic implant and/or residual bone, prompting immediate orbitotomy and restoration of normal extraocular muscle function. This report highlights the intricacies of orbital reconstruction, as well as the need for intraoperative forced duction testing.

A Method for Combining Thin and Thick Malleable Titanium Mesh in the Repair of Cranial Defects
INTRODUCTION Cranial defects following the removal of tumor involved bone require repair and reconstruction for brain protection and cosmesis. A variety of autologous bone substrates and synthetic materials can be employed, alone or in combination. In this article, we describe the use of dual thin and thick titanium mesh, connected together using plate hardware, to repair a right frontotemporal...
متن کاملModifications 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 کاملAnomalous origin of the ophthalmic artery from the anterior cerebral artery.
A 39-year-old woman presented with left visual disturbance and diplopia. Magnetic resonance imaging revealed a well-enhanced tumor in the left tentorium, cavernous sinus, and suprasellar region. Angiography demonstrated an abnormal origin of the ophthalmic artery from the anterior cerebral artery. The tumor was partially removed by left frontotemporal craniotomy with orbitozygomatic osteotomy. ...
متن کاملFronto-temporo-orbitozygomatic craniotomy and "half-and-half" approach for basilar apex aneurysms.
BACKGROUND Basilar apex aneurysms (BAA) are located in interpeduncular cistern surrounded by eloquent neurovascular structures. Surgical access is difficult due to narrow surgical corridors and requires traversing through a depth of 6-8 cm of subarachnoid space. AIM Surgical management of BAAs clipped using frontotemporal craniotomy, orbitozygomatic osteotomy with combined subtemporal and tra...
متن کاملExtended orbitozygomatic approach to the skull base to improve access to the cavernous sinus and optic chiasm.
BACKGROUND The orbitozygomatic approach to the skull base has evolved over the past century, with a surge in development during the past 20 years. We describe an extension of this technique involving removal of the most inferior portion of the temporal bone to the level of the internal carotid artery as it enters the carotid canal, to further facilitate exposure of tumors in this region.
