Transnasal endoscopic resection of pediatric orbital cyst: "How I do it" With Illustration and Video

Background: An orbital cystic lesion is a common orbital disease and has classically been approached via external incision. The introduction of endoscopic surgery has revolutionized the management of sinus and skull base disorders. Similarly, endoscopic techniques have been increasingly used to access intraorbital lesions with excellent outcomes, especially in pediatric patients. Objective: We described, in detail, the surgical technique of the endoscopic approach to treat a pediatric orbital cyst. Results: The cyst was completely resected, and the patient quickly recovered without any complication. Conclusion: The transnasal endoscopic surgical approach can be safe and effective for pediatric patients with orbital lesions. Use of this approach is based on the surgeon's experience and progressive instrumentation.
