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
