Whether adenoid facies can recover slowly with age depends on the timing of surgery and the severity of adenoid facies, and cannot be generalized. The adenoid face is mainly due to adenoid hypertrophy blocking the posterior nostrils, causing children to breathe with their mouths open for a long period of time, resulting in jaw and facial bone dysplasia, long maxilla, high palate arch, uneven teeth, protruding upper incisors, thickened lips, and lack of expression, also known as “dementia face”. If a child has adenoid face, he or she can recover gradually after 3-5 years by timely adenoidectomy if the disease is short-lived. In some children, the adenoid face may not be completely restored if the best time for surgery is missed because of the long duration of the disease and the age of the child. For children with adenoid hypertrophy, if it has affected breathing and sleep, or if symptoms such as snoring appear, timely intervention should be carried out to achieve early detection and treatment.
