Sialadenosis: 'non-inflammatory swelling of the salivary glands'
[[Category:Salivary_Glands_-_Pathology]]
Usually the masses are bilateral, uniform, fluctuant and painless, unless the cause of the swelling is neoplastic.
A salivary mucocele (accumulation of saliva in sub-cutaneous tissue) or a sialolith (a stone in the salivary duct) is the usual cause of swelling.
It is most common in dogs
== Clinical Signs ==
*Often non
*Retching/gulping sometimes seen
*Fever and pain seen if infected
*Occasionally dyspnea if obstructing the airway
== Diagnosis ==
*Palpation
*Aspiration<br>- viscous fluid (saliva) <br>- often serosangiunous or golden<br>- cytologically indifferent from saliva<br>- stain for mucus with periodic acid-schiff
*Sialography (rarely performed)- used to detect side of origin if difficult to palpate
*Biopsy (rarely performed unless neoplasia suspected) -no significant histological abnormalities in the [[Salivary Glands - Anatomy & Physiology|salivary gland]] biopsies.<br>
== Treatment ==
*Aspiration to temporarily relieve pressure and reduce size of mass
*Surgery for mucocele<br>- remove salivary gland and duct<br>- remove both sides if origin cannot be determined<br>- marsupialisation of ranula (if one is present)<br>- cervical drainage if removal is not anatomically possible
*Surgery for Sialolith<br>- incise over duct and allow to heal by secondary intention
== Prognosis ==
Very good if removal is complete
