Transorbital endoscopic assisted resection of a superior orbital fissure cavernous haemangioma: a technical case report

Abstract

The endoscopic-assisted transorbital approach should be considered a safe and effective option that can be applied in the treatment of lesions affecting such complex anatomical regions, as it offers excellent visualization of the surgical field, acceptable sequelae and reduced morbidity in relation to the traditional transcranial/transfacial approaches. Further studies and larger case series are needed in order to validate the reproducibility and range of applications of this surgical technique.

Endoscopic endonasal orbital cavernous hemangioma resection: global experience in techniques and outcomes

“…This is consistent with the fact that OCHs tend to be well encapsulated and rarely infiltrate adjacent structures. 13 As expected, tumors located within the intraconal space were associated with a greater incidence of incomplete removal and postoperative morbidity including new onset diplopia and enophthalmos. This may be attributed to the fact that approaches to the intraconal space mandate a larger orbitotomy as well as a greater degree of medial rectus instrumentation than extraconal lesions.…”

“…As endoscopic skull base techniques have become more widely utilized and accepted, however, approaches to the orbit have experienced a rebirth, with an increasing number of papers being published on the subject in recent years. 13,17 Consequently, this study was conceived in an effort to examine the independent endoscopic techniques developed at multiple experienced institutions to deal with a single type of lesion.…”

“…Although these lesions tend not to infiltrate into local tissue, they are capable of incorporating adjacent blood vessels and nerves into their capsule as they expand. 13 Histologically, OCHs demonstrate features of slow-growing venous lesions with mature cellular components that do not tend toward dysplasia or hypercellularity. Based on the classification of the International Society for the Study of Vascular Anomalies (ISSVA), these lesions should be characterized as slow-flow cavernous venous malformations.…”

Transorbital endoscopic assisted management of intraorbital lesions: lessons learned from our first 9 cases

“…Actually, non-transnasal endoscopic assisted approaches inside and around the orbit are quite neglected, with very few exceptions (6,7,16,17) . Given our widespread experience in balanced orbital decompression for Graves disease (18) as well as in endoscopic skull base surgery and transnasal intraorbital approaches (2)(3)(4) , Among the advantages of this technique, we strongly believe that the endoscopic visualization, that is able to bring light close to the structures, offers a really outstanding identification of the orbital details.…”

“…Endoscopicassisted not transnasal but transorbital approaches are quite neglected although transcutaneous orbital endoscopic surgery was pioneered and described in the early 80's (5) . Actually very few data concerning this surgical option are reported in literature (1,6,7) , and the number of cases collected is really limited.…”
