There is no clinical term for parotitis, which may be a protrusion of the cheeks on both sides, and usually does not recover on its own if it is due to heredity or other factors. In addition, the cheeks may refer to mumps, then the recovery time may be around 18 days. Some people have more prominent cheeks on both sides, i.e., wider jaw angle or enlarged bite muscles, which are mostly due to genetic factors and cannot recover by themselves. If such patients have obvious protruding jaws or asymmetry on both sides, they can choose to reduce chewing, botulinum toxin injections and surgical treatments according to their own conditions and the doctor’s recommendations, and there is a large individual variability in the recovery time. In addition, when some people say that they have mumps, they may be referring to mumps, which is an acute, self-limiting respiratory infectious disease caused by mumps virus infection and spreads through droplet transmission. The incubation period for mumps is usually between 8 and 30 days, with an average of about 18 days, and most patients gradually subside four to five days after the onset of the disease, but the complete cure is based on five days after the swelling of the parotid gland subsides. In daily life, when similar symptoms of mumps occur, such as fever, parotid gland swelling, pain and other symptoms, you need to consult a doctor in time.
