Abstract

Purpose: Tumors of the medial orbital apex can be challenging to resect. Primary endonasal resection can be limited by requirements for fat retraction and poor angulation for lateral orbital dissection. Orbital resection alone can have space limitations and a limited view for dissection of the posterior aspect of the tumor. The combined transorbital transnasal approach integrates the retraction and instrumentation advantages of the transorbital approach with the optical and space advantages of the transnasal approach. Methods: In this cross-sectional cohort study, patients who underwent surgical resection of an apical orbital tumor via a combined endoscopic and orbital approach from 2014 to 2019 were identified. Clinical history, examination findings, imaging, surgical technique, histopathology, and complications were reviewed. Results: Six patients were included. Patients presented with proptosis (5), optic neuropathy (3), and motility restriction (2). Surgery involved a medial orbitotomy and endoscopic ethmoidectomy ± sphenoidotomy, medial wall removal, and periosteum opening. The lesion was prolapsed into the sinus, dissected at the apex via the orbital approach, and removed through the nasal cavity. Pathologic diagnoses were cavernous venous malformation (4), venolymphatic malformation (1), and metastatic carcinoid (1). Improvement in pain (2/2), optic neuropathy (2/3), and proptosis (5/5) were noted. Complications included ethmoid mucocele and nasal polyps. Conclusions: The combined endonasal and orbital approach involves prolapsing the lesion into the nasal cavity to aid in dissection on the lateral and posterior aspects, maximizing visibility of the tight intraconal space. This technique can be performed by a team of orbital surgeons experienced in both orbital and endonasal surgery.
