Abstract :

Sialocele is a salivary gland cyst. Trauma to the any of the salivary glands results in disruption / interruption of the duct / parenchyma leading to extravasation of saliva into the glandular / peri glandular region resulting in cyst formation. It is most commonly associated with the parotid gland. This case documents an unusual swelling in the preauricular region – a post–traumatic parotid sialocele1–2. It illustrates trauma as an etiology of sialocele formation. Imaging plays an important role in establishing the diagnosis as well as the management. This report documents a case of a young male who developed a discharging sinus and swelling right side of face, one month after suturing a laceration, following a road traffic accident. Ultrasonography done revealed a multiloculated collection overlying the right parotid gland. A conventional sialography, CT sialography and MR done confirmed the swelling to be related to the right parotid gland with interruption of the Stenson’s duct and discharging sinus over the right cheek. The patient was managed conservatively with aspiration of the sialocele.
