Long face syndrome
What is Long face syndrome?
Long face syndrome, also referred to as skeletal open bite is a condition generally caused by childhood mouth breathing. However, a decreased airway size due to edema, an obstruction or genetics are other contributing factors. If the cause is mouth breathing, it generally occurs when children are unable to breathe through their noses, which changes the child's bite while they are still growing.
The condition's most striking symptom is an excessively long lower face height.
