Abstract
The objective of the study is to present our multicentric experience on intraorbital lesions managed by means of an endonasal endoscopic approach. The study design used was multi-institutional retrospective review. We collected data on 16 intraorbital medially-located lesions, all managed by means of an endonasal route, treated in four different skull base centers. We retrospectively reviewed the technical details, complications, histology, and general outcome. The endoscopic endonasal approach was effective in removing completely intraorbital extra-intraconal tumors in 8 cases, in performing biopsies for histological diagnosis in 6 intraorbital intraconal tumors, and in draining 1 extraconal abscess. No major complications were observed; in particular, there was no optic nerve damage. Minor, temporary complications (diplopia) were seen in 3 cases; only 2 patients experienced a permanent diplopia related to medial rectus muscle impairment, in 1 case associated with enophthalmos. Our preliminary multi-centric clinical experience suggests that medially located intraorbital lesions, and in particular the infero-medial ones, can be successfully and safely managed by such an approach. The well-known advantages of the endoscopic techniques, namely the lack of external scars, less bleeding, shorter hospital stay, and fewer complications, are confirmed.
