Olfactory neuroblastoma: results of combined therapy.

Olfactory neuroblastomas are seldom encountered in otolaryngologic practice. Eleven such patients were treated by combined therapy over a nine year period. Two cases who initially underwent surgery only required salvage for a local recurrence by a combined modality. Nine patients were disease-free at the end of two years, with four of them being so for five years. Adjuvant chemotherapy was used in four cases, one of whom developed distant cutaneous metastasis after two years. Craniofacial resection was performed on three patients. A combined therapy is recommended for all stages of olfactory neuroblastoma.
