Sialadenosis: 'non-inflammatory swelling of the salivary glands'
   −
[[Category:Salivary_Glands_-_Pathology]]
+
Usually the masses are&nbsp;bilateral, uniform, fluctuant&nbsp;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
 +
 
 +
&nbsp;
 +
 
 +
== Clinical Signs ==
 +
 
 +
*Often non
 +
*Retching/gulping sometimes seen
 +
*Fever and pain seen if infected
 +
*Occasionally dyspnea if obstructing the airway
 +
 
 +
&nbsp;
 +
 
 +
== 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
 +
 
 +
&nbsp;
 +
 
 +
== Prognosis ==
 +
 
 +
Very good if removal is complete
