Lateral approach to intraorbital lesions: anatomic and surgical considerations
Abstract
We present our microsurgical lateral orbital approach for intraorbital lesions, with special emphasis on the microanatomy of the orbit. Among 26 patients, such lesions included tumors of the lacrimal glands, cavernous angioma, meningioma, neuroma, and other tumors. These intraorbital lesions were removed through a 35- to 40-mm lateral skin incision, and this was followed by lateral orbitotomy featuring a microsurgical dissecting technique. If it was necessary to gain access to the deep lateral portion of the muscle cone, the lateral orbitotomy was extended to the anterior temporal dura. There are two microsurgical routes into the muscle cone, one above and the other below the lateral rectus muscle. The structures encountered along these two routes were demonstrated in an anatomic study of the orbit in cadavers. Lesions located in the lateral compartment of the orbit could be exposed through lateral orbitotomy and were completely removed in most cases. Complications in our series of 26 patients included one case of postoperative visual impairment, one case of tonic pupil, and three cases of transient impairment of eye movement. We think that, with an intimate understanding of the anatomy of the orbit, intraorbital lesions locate...Continue Reading

Cavernous Hemangioma
Cavernous hemangioma is a blood vessel defect or benign tumor that leads to leakage of blood to the surrounding tissues. This can occur in several organs including the brain, which can lead to seizures. Discover the latest research on cavernous hemangiomas here.
