Overview: What is Craniomandibular Osteopathy in Dogs?

Craniomandibular Osteopathy (CMO), also known as “lion jaw” or “westie jaw,” is a rare, non-neoplastic condition that affects the bones of a dog’s skull and jaw. It is primarily observed in young dogs, typically between the ages of 3 to 8 months, and is more common in certain breeds such as West Highland White Terriers, Scottish Terriers, and Cairn Terriers. However, CMO can occur in dogs of any breed.

In dogs with CMO, there is abnormal bone growth in the mandible (lower jaw), temporal bones (bones on the sides of the skull), and sometimes the maxilla (upper jaw). This excessive bone growth can lead to thickening and swelling of the affected areas, resulting in pain, difficulty in opening the mouth, and potential deformities in the facial structure.

The exact cause of Craniomandibular Osteopathy is not fully understood but is believed to have a genetic basis. It is thought to be an autosomal recessive trait, meaning that both parents must carry the gene for it to be passed on to their offspring. However, not all dogs with the genetic predisposition will develop the condition.

CMO is characterized by episodes of pain and swelling that can last for weeks to months, followed by periods of remission. The severity and frequency of these episodes can vary among individual dogs. While the condition can be distressing for both dogs and their owners, it is important to note that with proper management, affected dogs can still have a good quality of life.

In the following sections, we will explore the causes and symptoms of Craniomandibular Osteopathy in more detail, providing you with a comprehensive understanding of this condition and how to best support your dog if they are affected by it.

 

Causes and Symptoms of Craniomandibular Osteopathy in Dogs

Craniomandibular Osteopathy (CMO) in dogs is primarily caused by genetic factors. It is believed to be an autosomal recessive trait, meaning that both parents must carry the gene for CMO in order for their offspring to develop the condition. However, not all dogs with the genetic predisposition will necessarily develop CMO.

The specific gene mutation responsible for CMO has not yet been identified, but it is thought to affect the regulation of bone growth and remodeling in the affected areas of the skull and jaw.

When it comes to the symptoms of Craniomandibular Osteopathy, they can vary in severity and presentation. Some of the common signs to look out for include:

  1. Facial Swelling: One of the most noticeable symptoms of CMO is the swelling of the affected areas, particularly the jaw, temples, and sometimes the cheeks. This swelling can be intermittent and may come and go in episodes.
  2. Pain and Discomfort: Dogs with CMO often experience pain and discomfort in the affected areas. This can manifest as difficulty in opening the mouth, reluctance to eat hard food or chew toys, and sensitivity to touch around the jaw and skull.
  3. Difficulty in Eating: Due to the pain and swelling, dogs with CMO may have difficulty eating or show a decreased appetite. They may prefer softer food or have trouble fully opening their mouths to take in larger bites.
  4. Excessive Drooling: Excessive drooling or hypersalivation can be a sign of discomfort associated with CMO. The dog may have difficulty swallowing due to the swelling and pain, leading to increased saliva production.
  5. Changes in Facial Appearance: In some cases, CMO can lead to visible changes in the facial structure of affected dogs. This can include a “bulldog-like” appearance, with a wider and more square-shaped head.
  6. Fever and Lethargy: During episodes of active inflammation, dogs with CMO may exhibit fever and general lethargy as their bodies react to the condition.

 

It is important to note that the symptoms of CMO can resemble other dental or jaw-related conditions, so proper diagnosis by a veterinarian is crucial. In the next section, we will explore the diagnostic process for Craniomandibular Osteopathy in dogs, helping you understand how it is confirmed and differentiated from other conditions.

 

Diagnosing Craniomandibular Osteopathy in Dogs

Diagnosing Craniomandibular Osteopathy (CMO) in dogs involves a thorough veterinary examination, diagnostic imaging, and the process of differential diagnosis to rule out other possible conditions. Since the symptoms of CMO can resemble other dental or jaw-related issues, an accurate diagnosis is crucial for appropriate treatment and management.

Here are the key components of diagnosing CMO in dogs:

  1. Veterinary Examination: The first step in diagnosing CMO is a comprehensive physical examination by a veterinarian. They will assess your dog’s overall health, examine the affected areas, and evaluate their range of motion and discomfort. The veterinarian may also ask you about the history and progression of symptoms.
  2. Diagnostic Imaging: X-rays (radiographs) are an essential tool in diagnosing CMO. They allow the veterinarian to visualize the bones of the skull and jaw to detect any abnormalities or excessive bone growth. X-rays can provide valuable information about the extent and location of the affected areas. In some cases, a computed tomography (CT) scan may be recommended for a more detailed evaluation.
  3. Differential Diagnosis: Since the symptoms of CMO can overlap with other conditions, it is important to rule out alternative diagnoses. The veterinarian will consider other possible causes of facial swelling, pain, and difficulty in opening the mouth, such as dental infections, jaw fractures, or tumors. Blood tests may be conducted to assess the overall health of your dog and rule out any underlying systemic issues.
  4. Biopsy (in some cases): In certain situations where the diagnosis is not clear or to rule out other potential causes, a biopsy of the affected area may be recommended. A small sample of tissue is collected and examined under a microscope to confirm the presence of CMO.

 

Once the diagnosis of Craniomandibular Osteopathy is confirmed, your veterinarian will discuss the results with you and develop an appropriate treatment plan. Understanding the diagnostic process will help you advocate for your dog’s health and ensure they receive the necessary care. In the next section, we will explore the treatment and management options available for dogs with CMO.

 

Treatment and Management of Craniomandibular Osteopathy in Dogs

Treatment and management of Craniomandibular Osteopathy (CMO) in dogs aim to alleviate pain, reduce inflammation, and improve the overall quality of life for affected dogs. While there is no cure for CMO, there are various treatment options available to help manage the condition effectively. The specific approach may vary depending on the severity of symptoms and the individual needs of the dog.

Here are the key components of treating and managing Craniomandibular Osteopathy:

  1. Medications and Pain Management: Nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly prescribed to reduce pain and inflammation associated with CMO. These medications help relieve discomfort and improve the dog’s ability to eat and move their jaw. In some cases, additional pain management techniques such as the use of analgesics or corticosteroids may be considered.
  2. Nutritional Support: Proper nutrition plays a crucial role in managing CMO. Dogs with difficulty chewing or opening their mouths may benefit from a soft or mashed diet that is easier to consume. Your veterinarian may recommend specific diets or supplements to ensure your dog receives adequate nutrition during periods of active inflammation.
  3. Surgery and Other Treatments: In severe cases of CMO or if complications arise, surgical intervention may be necessary. Surgery aims to relieve pressure on the affected bones and improve the dog’s ability to open their mouth comfortably. The specific surgical procedure will depend on the individual case and may involve removing excessive bone growth or altering the jaw structure.
  4. Physical Therapy and Rehabilitation: Physical therapy techniques, such as gentle jaw exercises and massage, can help improve jaw mobility, reduce muscle stiffness, and enhance overall comfort for the dog. Your veterinarian or a specialized rehabilitation therapist can guide you on specific exercises and techniques to incorporate into your dog’s daily routine.
  5. Regular Veterinary Monitoring: Dogs with CMO require ongoing veterinary monitoring to assess their condition, manage pain, and address any potential complications. Regular check-ups, imaging studies, and blood work may be recommended to ensure the treatment plan is effective and adjusted as needed.

 

It is important to work closely with your veterinarian to develop a tailored treatment plan for your dog’s specific needs. They will guide you on medication dosages, dietary adjustments, and any additional supportive care that may be beneficial.

In the next section, we will discuss how to adapt your home environment and provide the necessary support to enhance your dog’s quality of life while living with Craniomandibular Osteopathy.
