Salivary Mucocele in Cats

Swelling of the soft connective tissues in an animal's mouth is referred to as an oral or salivary mucocele. The swelling appears like a mucus-filled sack and is more than three times as likely to form in dogs than in cats. However, all cat breeds are susceptible to oral or salivary mucoceles. Treatment is generally successful and involves draining the fluid and prescription antibiotics.

Symptoms and Types

Some of the most common signs of oral and salivary mucoceles are:

Facial swelling
Oral pain and swelling
Blood in the saliva
Difficulty swallowing
Eye pressure and pain
Respiratory disease or difficulties breathing
Soft, developing masses in the neck (cervical)

Causes

Bite wounds, ear canal surgery, blunt trauma to the face or head, and a blunt or foreign object penetrating inside the cat's mouth are all potential causes for oral and salivary mucoceles.

Diagnosis

The diagnosis will be based on a physical examination and a thorough history of your cat. There are rarely any laboratory or blood work abnormalities associated with this condition, and imaging is rarely used to diagnose oral or salivary mucoceles. The primary objective is to rule out any abnormal cell development, abscesses from infected teeth, or other more serious causes of the inflammation.
