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.
