[Radiotherapy : an option for refractory salivary fistulas]

A 45-year-old patient presented with refractory salivary fistula, attributed to multiple surgery and Botulinum toxin, following lateral parotidectomy. He underwent fractionated radiotherapy of the remaining parotid gland including the fistula opening (total dose of 30 Gy) at our clinic. In time, fistula secretion could be inhibited completely. Although the indication for radiotherapy for such fistulas is rare since Botulinum toxin has been in use, it should still be considered in refractory disease courses.
