Adenoid facies in adults cannot be completely corrected, but the appearance can be improved by correcting mouth breathing, orthodontics and orthognathic surgery. Adenoid facies refers to the appearance of a child’s narrow midface, high arched upper jaw, and crowded teeth that develops during development due to chronic obstruction of the nasal airways. Since the adult skeleton is well established, it cannot be restored by changing habits, and it is impossible to correct it completely even with the help of medical treatment. In order to improve the appearance of the face, the following treatments can be performed: 1. First of all, we need to find the cause of mouth breathing, common tonsil hypertrophy, inferior turbinate hypertrophy, chronic rhinitis or sinusitis, etc., to treat the cause of the disease, and then develop good breathing habits. 2. Orthodontic treatment: People with adenoid face often have uneven front teeth and different degree of convexity, through orthodontic treatment, good oral posture and occlusion can be restored, which is good for nasal breathing and improve the appearance. 3. Orthognathic Surgery: The above two methods achieve limited corrective effect, and if you want to get a more ideal facial appearance, you need to correct the three-dimensional position of the jawbone through surgery. Patients with adenoid facies are advised to seek active medical treatment as soon as possible to avoid aggravation of the condition.
