Abstract

Objective: This study aimed to present our initial experience to evaluate the feasibility of the different tranorbital endoscopic approaches as an adjuvant technique to endoscopic transnasal approach of the skull base and to evaluate the safety and efficacy of these approaches.
Background: Although endonasal approaches are highly expanded, they have limitations in dealing with some skull base lesions, including the inability to perform microsurgical dissection with complex lesions, access to the anterior cranial fossa laterally over the orbits away from the midline, and limited working space when multiple surgeons are working. The orbits appear to offer an excellent portal for endoscopic access to the skull base and adjacent craniofacial regions. Operating through the orbits might eliminate some of the challenges of the currently used transnasal approaches.
Materials and Methods: This study was conducted on 10 sides of dry skulls and 10 sides of fresh frozen cadavers for application of the new approach of transorbital neuroendoscopic surgery.
Results: Anatomical orientation of the orbit, skull base and adjacent craniofacial region appeared very easy during transorbital endoscopic dissection on the dry skull first then during our meticulous dissection on frozen cadavers. We expected no major complications should happen to patients underwent to TONES.
Conclusion: All transorbital endoscopic approaches to skull base are feasible, direct, effective and expected to be safe surgery. However, we need to conduct these approaches on life patients starting with minimal pathology as complicated sinusitis, fibro-osseous lesions and C.S.F. leak.
