First described by Berger in 1924, esthesioneuroblastoma (ENB) remains a rare sinonasal tumor believed to originate from specialized sensory olfactory cells. To date, the literature includes 1,000 recorded cases of ENB. Patients with ENB often present with non-specific symptoms, most often chronic nasal obstruction or epistaxis. Careful examination may reveal a pink or brown polyploid mass in the nasal cavity. Overall, ENB may demonstrate various growth patterns ranging from slow, indolent progression to aggressive invasion with widespread metastasis.

Current literature indicates that ENB should be treated with a combination of surgical resection and postoperative radiation therapy with or without chemotherapy. However, significant controversy remains regarding the appropriate surgical approach. This video demonstrates a transnasal endoscopic approach, which has gained significant popularity over the previous two decades compared to classic “open” approaches. Although this approach demonstrates improved perioperative outcomes while still achieving oncologic margins, further work is required to evaluate long-term survival.
