Q-Chiang is a spayed female chocolate Poodle, at the time of treatment, she was 7 years and 10 and a half months old.

The patient has a history of severe periodontal disease. In 2022, the owner noticed that the maxillary right canine of her had fallen out, leaving a gap that communicated directly with the nasal cavity. The owner initially took the dog to a nearby animal hospital, and then was referred to our hospital for further evaluation and treatment. After examination by Dr. Chung-Wei Chen (Dr. Richard Chen), it was diagnosed as an oronasal fistula of the maxillary right canine (104).

Due to complete loss of alveolar bone in the affected area and insufficient thickness of the gingiva, the conventional coronally positioned flap surgery could result in excessive tension and lead to flap rupture and surgical failure. Therefore, after assessment, Dr. Chung-Wei Chen (Dr. Richard Chen) decided to perform the surgery using the "rotation flap" technique, which allows for the use of a "tension-free flap" for suturing and ensures better healing.

During the follow-up visit 6 months after the surgery, the oronasal fistula had completely closed, and the healing was excellent. The oral and nasal cavities were thoroughly separated, eliminating the risk of reinfection. The dog's living condition is good, and there were no symptoms such as sneezing or nasal discharge.

Severe periodontal disease in dogs and cats not only leads to tooth loss and oral abnormalities but can also trigger other complications affecting various organs in the body. These systemic diseases include atherosclerosis, thrombosis, and increase the likelihood of developing the following diseases, including myocardial infarction (MI), stroke, infective endocarditis, diabetes, respiratory diseases, dementia (cognitive dysfunction syndrome, CDS), etc.

Therefore, it is essential for owners to clean their dogs' and cats' teeth daily and maintain good oral hygiene to safeguard their overall health.
