The transorbital neuroendoscopic surgery (TONES), endoscopic transnasal skull base procedures, and the concept of multiportal minimal access neurosurgery are novel, rapidly evolving approaches in the management of complex skull base lesions. A 27-year-old male presented with a history of road traffic accident with nasal bleed, cerebrospinal fluid (CSF) rhinorrhea, and left eye deformity. There was left upper eyelid ecchymosis, orbital dystopia, left pupil was dilated, and fixed with no extraocular movements. The computed tomography scan showed basifrontal contusion and complex comminuted anterior cranial fossa (ACF) fracture involving left cribriform plate and left orbital roof with fracture fragment impinging on the superior rectus muscle with suspicious orbital CSF leak. There was no improvement with conservative management. Hence, a novel combined TONES, transnasal endoscopic multiportal surgery was undertaken for the removal of fracture fragments and multi-layered closure of the complex ACF defect. The patient had a complete resolution of orbital dystopia and visual loss with no evidence of CSF leak postoperatively.
