RESUMO
OBJECTIVE: An increasing number of transnasal endoscopic surgical procedures are being performed, and these procedures are now also utilised in the management of malignant sinonasal tumours. This study aimed to evaluate the outcome of endoscopic resection of sinonasal malignancies, with or without chemotherapy and radiotherapy. METHODS: Between 2000 and 2009, six patients with sinonasal malignancies (diagnosed on pre-operative biopsy) underwent endoscopic resection at our hospital. The histopathological diagnoses varied and included squamous cell carcinoma, olfactory neuroblastoma, chordoma, extramedullary plasmacytoma and haemangiopericytoma. RESULTS: Surgical resection was combined with chemotherapy and/or radiotherapy in four cases. The mean follow-up period was 43 months. One patient suffered local recurrence of chordoma, 84 months after the first operation, but this was successfully treated with proton beam radiotherapy. CONCLUSION: These results suggest that endoscopic resection may be a valid alternative to conventional resection in selected cases of malignant sinonasal tumour.

OBJECTIVE: To report the safe management and treatment of a catecholamine-secreting tympanicum glomus tumour. CASE REPORT: A 73-year-old women presented with a catecholamine-producing glomus tympanicum tumour, complaining of hearing impairment and left ear pain. Physical examination revealed a red, pulsating swelling in the left tympanic membrane. Computed tomography demonstrated a soft tissue mass filling the entire middle-ear cavity and a partial osteolytic lesion in the internal carotid artery. Angiographic examination revealed a densely contrasting tumour with feeding vessels from the ascending pharyngeal artery. Concentrations of serum noradrenalin and urine vanillylmandelic acid (VMA) were high. The tumour was completely resected using a potassium titanyl phosphate laser, the feeding vessels having been embolised the previous day. Concentrations of serum noradrenalin and urine VMA normalised following the operation. CONCLUSION: Pre-operative embolisation is useful in the treatment of catecholamine-secreting tympanicum glomus tumours, not only for preventing a hypertensive crisis but also for reducing bleeding. The potassium titanyl phosphate laser is useful for complete resection of the tumour.
