What is Salivary Mucocele?

Canines have salivary glands under their tongues and in the back of their mouths.  Salivary glands produce saliva, which then goes through a salivary duct to the mouth, where it helps with the digestion process.  If a gland or duct gets damaged, saliva leaks into surrounding tissue and collects. Mucoceles are typically soft and non-painful, unless a secondary bacterial infection is present. Pharyngeal mucocele can make it difficult for the canine to breathe or swallow.

Salivary mucocele can develop into a major problem because the saliva is being constantly produced and the body is unable to reabsorb it all. The area where the saliva is being collected continues to grow and may form cysts. The problem will not just go away, you must take your pet to the veterinarian. The longer you wait, the more difficult it will be for your veterinarian to determine which salivary gland has ruptured.  

All breeds are susceptible to mucocele but there is an increased incidence in German Shepherds, Australian Silky Terriers, Poodles, and Dachshunds. Mucocele has no age predisposition; young or older dogs may develop the condition.

A salivary mucocele occurs when a collection of saliva leaks from a canine’s damaged salivary gland or salivary duct and collects in the surrounding tissues. This condition causes painless swelling of the neck or within the oral cavity.

Types 

  • Cervical mucocele - This is the most common type of mucocele; the saliva collects in the upper neck region, under the jaw, or in between the jaw
  • Ranula mucocele - Another common location for the formation of a mucocele; the saliva collects beneath the tongue alongside the tongue

Diagnosis of Salivary Mucocele in Dogs

Your veterinarian will go over your pet’s medical history and he will ask you when the swelling first started.  During the physical examination your veterinarian will gently palpate the area.  Usually mucoceles are easily identified; tumors and abscesses may appear similar but are generally firm and painful. Your veterinarian may recommend a sterile aspiration of the fluid in the mass. In mucocele the aspiration will be a clear blood tinged thick ropy fluid. The aspirated fluid will also be examined under the microscope. High white blood cell count in the fluid may indicate an infection in the salivary gland or an abscess.

Your veterinarian team will need to perform surgery to find the ruptured duct.  To make sure your pet is healthy and can undergo surgery, a complete blood work (CBC), urine test, and chemistry profile will be recommended.

Treatment of Salivary Mucocele in Dogs

The only suitable treatment for salivary mucocele is surgery to remove the ruptured gland or glands involved. Aspiration or draining of the mass will only resolve the problem for a short amount of time.  

Ranulas, cervical and pharyngeal mucoceles are all treated by surgical removal of the mandibular and sublingual glands of the affected side. A zygomatic mucocele means the gland needs to be removed from beneath the eye.

Recovery of Salivary Mucocele in Dogs

Following surgery your pet will receive pain medication; the veterinarian will prescribe nonsteroidal anti-inflammatories, local anesthetics, and narcotics to control the pain.  Most patients can go home on the same day as the surgery.  If the surgery was more complicated, your pet may need to remain hospitalized overnight. Once your pet is home, he can’t be allowed to scratch at the incision; the use of an Elizabethan collar will be necessary. Movement and exercise is usually restricted for about 3 weeks after surgery.  Follow-up visits will be necessary to check the incision and for the removal of the drain. Make sure to call your veterinarian if your pet experiences breathing difficulties, if there is swelling or bleeding of the incision.

The prognosis following surgery is very good. Removal of a set of salivary glands will not alter your pet’s salivary function, the other glands will take over the work. The recurrence of the mucocele is very uncommon.

Chronic salivary mucocele. Had surgery twice. Two necrotic glands removed. Due to scarring, I hate more surgery in the area, but clearly, there’s more leakage. Anything else I could do?

There are limited options with salivary mucocele which include surgical removal, marsupialization or frequent aspiration. Unfortunately there are not many choices available for these types of cases. Regards Dr Callum Turner DVM www.acvs.org/small-animal/salivary-mucocele

Max had a partial mandibulectomy. 4 weeks later he has a sublingual mucocele. He had it surgically unblocked. Does it matter if he eats soft or hard food moving forward?

Thank you for your question. Without knowing more about Max and his condition, it sounds like he has had a fair amount of trauma and surgery around his mouth, and he would probably appreciate soft food until he is fully recovered. Once he has recovered, you should be able to feed whichever food he prefers, but it would be a good idea to ask your veterinarian, as they know more about his health status.
