Anatomic Evaluation of Endoscopic Transnasal Transorbital Approach to the Lateral Orbital Apex

Abstract

In patients whose vision is irreparably damaged, one might consider an endoscopic approach to lesions of the lateral orbital apex. Approach in patients with intact vision should be handled with caution because of possible traction of the optic nerve.

Endoscopic endonasal approach to the lateral orbital apex: case report

“…Here, we describe the first case performed in a living patient. 8 The choice of surgical approach to the orbit is generally determined by location, extension, and the type of lesion. As a rule, cosmetics and accessibility are both con- sidered.…”

“…In the literature there are anatomical descriptions of approaches in cadavers to the orbit with visualization of the space lateral to the optic nerve. 8,14 According to the authors, this approach can be safely used only in patients who have lost their vision because of the high risk of optic nerve damage. 8 The patient described in this report had no problems with vision or eye movements before surgery and no new deficits after surgery.…”

“…8,14 According to the authors, this approach can be safely used only in patients who have lost their vision because of the high risk of optic nerve damage. 8 The patient described in this report had no problems with vision or eye movements before surgery and no new deficits after surgery. In the paper by Kenyon and Antisdel, the authors described an endoscopic approach to the lateral orbital apex in a cadaver.…”

“…1,5,11,13 However, using a transmaxillary transpterygoidal corridor, a path inferior to the periorbita of the orbital apex can be used to reach the compartment lateral to the orbital apex. 7,8 Although feasibility has been provided through cadaver dissection, a clinical case report has not yet been described. Rhabdomyosarcoma is a rare and malignant tumor that mainly affects pediatric patients.…”

“…Craig et al 23 describe how upper lateral strut grafts improved patency in cadaveric internal nasal valves, most notably in cadavers with narrow internal nasal valves. Kenyon and Antisdel 24 offer an alternative for patients in need of surgery involving the lateral orbital apex. In their cadaveric study, endoscopic approaches to the lateral orbital apex are explored.…”
