Cheeks are usually caused by overdeveloped facial biting muscles, and may also be caused by fat accumulation due to obesity and other reasons. If the patient usually exerts too much force on the biting muscle due to chewing betel nut, chewing gum and other difficult to chew foods, then it will lead to excessive muscle growth and development, resulting in bilateral jaw widening and enlargement. Botulinum toxin can be injected locally to inhibit the contraction of some of the biting muscles to improve the appearance of an enlarged bite. When the patient’s body increases significantly, the subcutaneous fat in the face and neck increases and accumulates in the lower part of the face, and due to the influence of gravity, the facial fat sags downward and accumulates in the cheek area, forming the condition of hairy cheeks. Additionally, gills may be caused by natural aging and facial skin laxity. It is recommended that patients who are willing to treat their gills go to a regular hospital for a consultation and follow the doctor’s instructions to choose an appropriate treatment plan.
