Popis: The intended use of the brain needle (Fig. 1) is the irradiation of brain tumours using a stereotactic technique (Mantell et al, 1986). We have adapted the needle to suit another purpose. A patient with a mixed tumour of the right paranasal sinuses was treated by initial chemotherapy followed by maxillectomy, leaving a large cavity extending to the roof of the sphenoid sinus, where histology of the resected specimen showed residual squamous cell carcinoma. Post-operative external irradiation using 8 MV X rays was given to the entire operated volume as a dose of 5000 cGy in 24 fractions over 36 days. It was intended to boost the dose to the region of the sphenoid sinus to minimize the risk of recurrence at this site, while keeping the dose to the brain stem within tolerance.
