Problems solved by technology

There is no good treatment for this kind of small mouth deformity. At present, surgical treatment is the main treatment, but scar contracture will still remain after surgical treatment. If it is not effectively controlled, the patient needs to undergo multiple operations to achieve a certain opening.

Moreover, the small mouth deformity is very easy to recur due to the surgical incision after the small mouth surgery, and it still recurs even after 3 times of surgery.

In order to maintain the effect of the operation and maintain the mouth opening, the patient usually uses a medicine bottle in the mouth to widen the mouth opening, but this method has the following disadvantages: 1. It is inconvenient for the patient to breathe; 2. There is saliva flowing out, which is inconvenient for nursing and also affects the patient. hygiene image
