Objective:
We describe sialography as a dynamic imaging modality useful in establishing the diagnosis and planning for treatment of a parotid gland ductal foreign body.
Methods:
Chart and radiographic imaging review of a 75 year-old male who had obstructive sialadenitis symptoms two years after welding slag pierced the cheek skin and identified as a 'piece of steel stuck in his cheek'.
Results:
Sialography was used to demonstrate a foreign body adjacent to the parotid gland to indicate its presence as a mobile element within the ductal system associated with marked pre-obstructive duct dilation. Sialendoscopy was used to successfully remove the foreign body.
Conclusions:
In selected cases, the management of obstructive sialadenitis can be improved with sialography in permitting dynamic imaging of salivary duct anatomy. Although ultrasound has evolved as a standard component of salivary gland assessment, sialography may complement imaging with ultrasound (or CT as in this case) to offer the highest acuity definition of the salivary ducts.
