Adenoid facies usually appear gradually between the ages of 3 and 5 years and become stable around the age of 8 years. Adenoid facies generally refers to abnormal enlargement of adenoid tissue, which causes craniofacial deformities. The main features of the patient’s appearance are the lengthening of the upper jaw, the deformation of the teeth, and the shortening of the upper lip. Some patients with severe disease may even have adverse effects on the respiratory system, causing secondary symptoms such as poor breathing, headache and dizziness, and mental depression. Patients show a gradual worsening of manifest symptoms as they grow older until the age of 8 years, while they stabilize and settle by the age of about 8 years. Currently, adenoidectomy is the most direct and effective treatment for adenoid hypertrophy, and the entire procedure takes only about 15 minutes to complete, featuring rapid treatment and a safe process. For patients with adenoid facies, the principle of early detection and early treatment should be adopted to avoid significant impact on the child’s future development and growth.
