*Special Reminder: Mucogingival Replacement Surgery (MGRS) is a pioneering and innovative surgical technique for treating stomatitis and oral soft tissue in animals, developed globally by Dr. Chung-Wei Chen. This technique has never been publicly disclosed or taught to others. If you hear or see any messages or promotional materials elsewhere claiming “the use of MGRS to treat stomatitis in dogs and cats,” please be aware that these claims have no association with the research and development techniques of Dr. Chung-Wei Chen. Please do not believe in them. Thank you for your understanding and cooperation.

“Midori” is a spayed female Norwegian Forest Cat suffering from severe Feline Chronic Gingivostomatitis (FCGS). The inflammation extends from the gingiva and oral mucosa on the buccal side to the caudal oral cavity, causing severe swelling in the oral cavity. The bilateral mandibular first molars (309, 409) on the buccal side exhibit inflammation, occlusal trauma, and traumatic granuloma due to concurrent oral inflammation, leading to significant pain and a severe impact on Midori’s appetite. Midori had previously been using medications to control the oral inflammation, but tolerance gradually developed. Referred by a animal hospital in Taipei, the owner brought Midori to our hospital for treatment using Dr. Chung-Wei Chen’s unique Mucogingival Replacement Surgery (MGRS) for FCGS. At the start of treatment, Midori was 3 years and 11 months old, and the MGRS treatment concluded when she was 4 years and 11 months old.

After a year of MGRS treatment, Midori’s FCGS completely healed, and Dr. Chung-Wei Chen successfully preserved all her teeth without extraction. Midori’s weight increased from 3.8 kg to 4.75 kg, and she can now lead a normal life without the need for injections or medications. Despite the successful resolution of FCGS, Midori also suffered from severe periodontal disease, requiring daily tooth brushing and regular dental scaling to maintain good oral hygiene and ensure overall oral health.

Thanks to the animal hospital in Taipei for referring this case to our hospital for treatment.

Feline chronic gingivostomatitis (FCGS) is one of the common oral diseases in cats. The main symptoms are:
1.     The gingiva and oral mucosa are red, swollen, ulcers or hyperplasia. All soft tissues in the mouth, including the gingiva and all parts of the oral mucosa (including buccal, lingual, sublingual and oropharynx, etc.), will have redness, ulceration or hyperplasia.
2.     Cats will lose their appetite or even refuse to eat because of mouth pain, or they will keep shaking their heads and scratching their mouths with their front feet when eating and drinking.
3.     The patient’s saliva usually has a peculiar smell, even putrefactive odor, due to ulcers.

At present, the most common treatments are long-acting steroid injections or oral steroids, combined with antibiotics, and tooth extraction, etc., but the effect of individual treatment varies greatly, furthermore, tooth extraction will likely cause the cat’s oral cavity to collapse and alveolar bone loss. They need lifelong medication and can’t stop it.

Dr. Chung-Wei Chen’s original Mucogingival Replacement Surgery (MGRS) aims to solve the above-mentioned sequelae and difficulties in the treatment of stomatitis, and make cats with FCGS no longer need to take medicine for a long time after recovery, and return to the normal life they had before the illness.
