Abstract

Objective:

We present an extremely rare case of a 44-year-old woman with right gustatory otorrhoea and otalgia.

Case report:

The patient had been initially treated for otitis externa after Pseudomonas aeruginosa was grown from a microbiological swab. The otorrhoea fluid was collected and tested positive for amylase. Sialography and computed tomography imaging of the temporal bone confirmed a sialo-aural fistula from the right parotid gland to the bony external acoustic meatus. The defect was consistent with a patent foramen of Huschke. The fistula was identified surgically via a superficial parotidectomy approach, after contrast injection of Bonney's blue dye into the parotid duct, and then ligated and divided. The patient had immediate and sustained resolution of her otorrhoea.

Conclusions:

Sialo-aural fistulae are extremely rare, and usually arise as a complication of surgery or as an acquired disease process. To date, only four cases have been reported. This case demonstrates the use of sensitive investigation involving sialography and computed tomography, as well as successful surgical management, with complete resolution of symptoms.
