Endoscopic transorbital surgery is gaining popularity among skull base surgeons and neurosurgeons to gain access to orbital and intracranial lesions. Given its minimal morbidity, better cosmetic result and minimal retraction, it provides an alternative minimal invasive approach to approach orbital, intracranial and skull base lesions. Skull base lesions involving the infratemporal fossa, pterygopalatine fossa and parapharyngeal space can thus be resected with endoscopic transorbital approach, as part of the multi-portal endoscopic surgery.
We have performed over 30 endoscopic transorbital surgeries in Queen Elizabeth Hospital since January 2020, including orbital tumors, sphenoid wing meningiomas, trigeminal schwannomas and malignant tumors involving multiple compartments. Case selection, surgical techniques, clinical outcome, complication avoidance, as well as application of multiportal endoscopic skull base tumor surgery will be discussed.
