Abstract

Background

Olfactory neuroblastoma, also known as esthesioneuroblastoma, accounts for only 3–6% of sinonasal malignancies but confers a 40% 5-year overall survival.

Method

The authors describe techniques for the endonasal, minimally invasive resection of an esthesioneuroblastoma in a 69-year-old man who presented with headaches and anosmia and describe surgical nuances and their effect on adjuvant therapy planning.

Conclusion

This approach, along with microsurgical techniques, helped increase tumor visualization, improved marginal resection, and reduced surgical risk, which may improve patient outcomes. Multilayered reconstruction with a synthetic dural substitute and creation of a nasoseptal flap were performed to reduce postoperative cerebrospinal fluid leak.
