Understanding What is Sialocele in Dogs and its Symptoms

The disorder of the oropharynx or ducts is known as sialocele. The disease is indicated by swollen tissues in the neck, around the jaw, underneath the tongue, or near the eye. In dogs, it’s an accumulation of saliva that looks like a cyst and is generally cured with surgery.

What is a Sialocele, exactly?

Due to leaking, a sialocele is a buildup of saliva in the tissues around a salivary gland or duct. Salivary mucoceles and salivary cysts are other names for sialoceles. Although not essentially a cyst, the fluid overload generates an excessive formation that looks like one. They’re soft, fluid-filled, and unpleasant in general. Although sialoceles are uncommon in dogs, they are the most prevalent form of salivary issue observed in humans. If you suspect your dog has sialocele, you should consult a vet at Virginia Beach veterinary hospital.

Sialoceles do not produce discomfort until they have grown large enough to push against another part of the body. Symptoms vary depending on the kind of sialocele.


  • Neck swelling behind the jaw
  • Under the tongue swelling
  • Swelling of the eyelids (rare)
  • Having difficulty eating, chewing, or inhaling
  • Neck and Jaw Swelling (Cervical)

The most prominent variety of sialoceles is the neck, which arises from the sublingual or mandibular duct and develops underneath the neck area or jaw. Inflammation can happen in the center of the neck/jaw or on one side.

Under the Tongue Swelling (Sublingual)

Another type of sialocele is one that develops underneath the tongue and is caused by the submandibular duct. The sialocele can be in the middle or on one side, and if large enough, it can shift the tongue. A sublingual or ranula sialocele is the name for this form of sialocele.

Swelling of the Eyelids (Zygomatic)

In rare circumstances, a sialocele arises from the tiny zygomatic salivary glands behind the eye. Facial edema may emerge near the eye, causing the eye to protrude.

Having difficulty eating, ingesting, or inhaling (Pharyngeal)

A pharyngeal sialocele is a pharyngeal sialocele that occurs at the base of the neck. It is analogous to a cervical sialocele because it arises from the mandibular or submandibular glandular or ducts. Sucking and breathing can be affected by pharyngeal sialoceles.

Sialoceles’ Causes

The specific etiology of sialoceles is unknown. However, acute damage to the membranes of the mouth and throat, and ducts are most likely to blame. The following are the three most likely causes:

  • Chewing on an item causes oral damage.
  • Another animal’s bite wounds
  • Pulling causes a choke collar injury.
  • Sialoceles can afflict any dog breed; however, it is more common in German shepherds and Australian silky terriers.

Sialoceles in Dogs Diagnosis

After discussing your pet’s medical history, your vet will undertake a medical examination and examine the swollen region attentively. The two stages of diagnosis are as follows:

Your veterinarian may use a sterile needle to aspirate the region to scoop up the fluid for testing. Depending on the situation, your dog may require sedation.

The liquid from a sialocele is transparent, pale yellow, or blood-tinged in color and mildly viscous, similar to saliva. Your veterinarian may recognize saliva right away, but to be sure, he or she will send the fluid to a laboratory for analysis. A medical pathologist will examine the fluid to establish the types of cells present and whether the bulge is a sialocele. Infections, tumors, and other possible causes of edema can all be ruled out with this test.


Sialoceles can develop infected and abscessed if not treated. Contact your veterinary hospital if you observe any abnormal swelling in your mouth, neck, jaw, or eye. Sialoceles are usually treated with draining and, subsequently, surgery. Here are the two therapy options:

Draining: A sialocele can be emptied in some circumstances to provide temporary relief before surgery can be undertaken. After being drained, most sialoceles will ultimately return. Flushing should not be done indefinitely since it might cause irritation or infection.

Surgery: Surgical excision of the afflicted salivary glands and accompanying ducts is the definitive therapy for sialoceles. A board-certified veterinary surgeon is usually the one who performs this delicate treatment. To avoid additional fluid collection, drains may be momentarily implanted at the surgical site.…
