Dietary care The mandibular angle surgery removed part of the masseter muscle, and the auxiliary materials were tightly wrapped, which led to the patient's limited mouth opening and decreased taste function, and he could not eat normally, but his appetite and digestive function were excellent. Therefore, after operation, he was given full liquid food with high protein, high calorie and little residue for 3 days. After removing the dressing, he was replaced with ordinary soft food, so that the patient could try to open his mouth and taste the function of muscles and occlusal joints as soon as possible. Use methods such as listening to music to divert attention and relieve patients' pain. Observe the dressing situation of oral materials, and take a semi-supine position after mandibular angle surgery. In particular, the blisters at the mandibular angle and submandibular skin caused by over-tight dressing should be asked about the patient's feelings and adjusted in time. Some patients still had oral foreign body sensation after removing stitches, and the stitches were removed 10 day after operation. Tell the patient that this is oral mucosal hyperplasia caused by surgery, and it will gradually subside after more than 1 month, so don't panic. And told patients to stick to mouth-opening exercise and chewing exercise for about half a year; It will take some time for facial edema to disappear completely.
