Open Mouth –lips Apart
The term “adenoid face” is to describe the facial characteristics of children with severely enlarged adenoids. The adenoids are a mass of soft tissue behind the nasal cavity. Like lymph nodes, adenoids are part of the immune system and are made of the same type of tissue (lymphoid tissue). White blood cells circulate through the adenoids and other lymphoid tissue, reacting to foreign invaders in the body.
When the adenoids are enlarged, they force children to breathe with an open mouth. This open mouth posture changes their facial appearance.
The typical features of an adenoid face include:
Facial features flattened
Narrow and vaulted palate
