Nasal endoscopic and anterior craniotomy resection for esthesioneuroblastoma: how we did it.

The objective of this study was to report and present an approach to combine functional and esthetic technique of endoscopic nasal tumor resection with anterior cranial fossa extension resection in a case of Esthesioneuroblastoma (ENB), a rare slow growing malignant neoplasm of the olfactory mucosa. For this purpose, the mass was excised by nasal endoscopic approach with microdebrider and anterior craniotomy with bi-coronal incision. The cribriform plate defect was reconstructed with temporalis fascia and nasal defect with fascia and rotated middle turbinate. Radiotherapy was given. At 4 years follow up no evidence of tumor locally or systemic metastasis were seen. In conclusion endoscopic excision complimented with anterior craniotomy for the anterior cranial fossa extension of resectable ENB with post-op radiotherapy is an effective treatment modality satisfying both oncosurgical as well as esthetic requirements.
