This is Boris at recheck following removal of two large cysts in each of his lower jaws. It is important to not that he is a six year old boxer dog and these cysts start forming at 6 months of age. Read below for more details on his story
Boris is seen here before surgery laying on his back under anesthia. You can see the swelling and dermatitis on the right side due to the cyst rupturing after eating away the jaw bone and entering the tissue.
Most dogs do not show signs with cysts until they are 6-8 years of age. As you can see this is the case on the same side of the jaw, which looks perfectly normal looking from inside the mouth
Again although there are no outward symptoms or changes in the tissue this dental x-ray shows the left jaw and the damage that cyst has created.
The outside portion of the whole jaw has been destroyed by the cyst as seen here. Treatment involves removing the cyst and the associated teeth then contouring the bone for closure.
