Long-term results of endoscopic-assisted cranionasal resection for olfactory neuroblastoma - single centre experience of fourteen patients.

Bilateral Synchronous Ectopic Ethmoid Sinus Olfactory Neuroblastoma: A Case Report

BACKGROUND Olfactory neuroblastoma (ONB), also known as esthesioneuroblastoma, is a rare malignant head and neck cancer thought to originate from the olfactory epithelium. It typically invades contiguous structures at presentation. We report a very rare case of multifocal and ectopic ONB. CASE REPORT A 41-year-old man presented with left nasal obstruction and occasional left epistaxis associa...

Endonasal endoscopic resection and radiotherapy in olfactory neuroblastoma: our experience.

BACKGROUND Our aim was to evaluate the efficacy of a bimodal method of treatment consisting in endoscopic resection followed by radiotherapy in patients with olfactory neuroblastoma (ON). METHODS This is a retrospective review on 10 patients with ON treated at a tertiary referral center. All the patients were treated with endonasal endoscopic resection, and 1 refused postoperative radiotherap...

Endoscopic-assisted craniofacial resection: a case series and post-operative outcome.

Craniofacial resection is commonly performed in the surgical resection of sinonasal tumours involving anterior skull base. It entails a bicoronal scalp flap with lateral rhinotomy or an extended lateral rhinotomy to expose the anterior skull base. Transfacial approach is necessary in the resection of the nasal part of the tumour. The choice of surgical approach is based heavily on the surgeon's...

Preservation of Olfaction after Unilateral Endoscopic Approach for Resection of Esthesioneuroblastoma

Objectives We present a case of olfactory preservation after a unilateral transcribriform transethmoidal endoscopic resection of esthesioneuroblastoma. We also discuss the oncologic results of endoscopic and transcranial approaches and describe the potential benefits and limitations of an endoscopic approach. Setting Single academic medical center. Participant and Design The clinical course of ...
