We have used ultrasound guidance in the operating theater to localize parotid calculi while manipulating and milking the calculi through the opening of the Stensen duct
. Dilation of the opening of the duct is performed with a blunt probe.
Specifically, there is less concern about facial nerve injury but more concern about injury to the Stensen duct
. (2) While malignancies of the accessory parotid gland are rare, when they do occur they jeopardize ductal integrity.
The typical presentation of NSP included swelling and erythema of the skin overlying the parotid gland, as well as a purulent discharge from the Stensen duct
. (2) Systemic symptoms are often present and may include fever, poor oral intake, and irritability.
Conventional sialography demonstrated a normal flow of the contrast medium through the left Stensen duct
, and the left parotid gland was enhanced as usual.
