Olfactory neuroblastoma is a rare malignant tumour, usually diagnosed at advanced stages. We studied 3 patients who were treated at our Institute between 1991 and 1999. One patient presented with a stage A and 2 with a stage B tumour. One patient presented with coma due to inappropriate secretion of antidiuretic hormone associated with a stage B tumour. All 3 patients were treated with complete surgical resection via a lateral rhinotomy approach and postoperative radiotherapy. There was no involvement of the cribriform plate. One patient developed a metachronous regional metastasis and was treated with neck dissection and radiotherapy. All 3 patients are free from recurrence with a follow-up period of 9 years, 18 months and 1 year, respectively. Combination therapy is the cornerstone of treatment for olfactory neuroblastoma. Complete surgical resection is the most important prognostic factor and can be accomplished via lateral rhinotomy for early stage tumours.
