[Labial function].
Lips should be considered as a phylogenic summary for nasolabial and facial mask evolution. They're the centre point of facial morphogenesis. The progressive development of oral and facial functions is a specific human necessity: feeding, suction, oral competence, swallowing, language and mimics. Each discontinuity create function and anatomic failures. Each damage create facial unbalance.
