Description

Sialadenosis: 'non-inflammatory swelling of the salivary glands'

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
- viscous fluid (saliva)
- often serosangiunous or golden
- cytologically indifferent from saliva
- 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 gland biopsies.

Treatment

Aspiration to temporarily relieve pressure and reduce size of mass
Surgery for mucocele
- remove salivary gland and duct
- remove both sides if origin cannot be determined
- marsupialisation of ranula (if one is present)
- cervical drainage if removal is not anatomically possible
Surgery for Sialolith
- incise over duct and allow to heal by secondary intention

Prognosis

Very good if removal is complete
