Abstract:
The purpose of this article is to report a case of esthesioneuroblastoma involving the bilateral paranasal sinuses, which was excised using an endoscopic-assisted transfacial approach. A patient presented with nasal swelling and left-sided nasal obstruction, epistaxis, and diplopia. Examination revealed broadening of the nasal dorsum with a fleshy pink mass in both nasal cavities. Computed tomographic scan showed a mass involving the nasal cavity and paranasal sinuses on both sides. The tumor was diagnosed as group C esthesioneuroblastoma. The mass was excised by bilateral medial maxillectomy and bilateral frontoethmoidectomy. Using a 0 degrees endoscope, the attachment of the tumor to the cribriform plate was identified and resected using a motordrill. On Waroff staining, Hispathology slides suggested esthesioneuroblastoma. The patient was asymptomatic for 1 year, following which he developed infection of the nasal cavity for which he had no form of treatment. He subsequently developed maggots in the nasal cavity after which he died. An endoscopic resection of the cribriform plate from the nasal cavity without a formal craniofacial resection can be safely performed with oncologic safety.
