Abstract:
Congenital unilateral lower lip paralysis (CULLP) is a rare condition characterized by inversion and absent depressive movement of the affected lower lip while moving the mouth, which is recognized when the infant cries. CULLP is a variation of facial paralysis caused by abnormal development of marginal mandibular nerve, hypoplasia of the depressor labii inferioris muscle or depressor anguli oris muscle. This report introduces two cases of congenital unilateral lower lip palsy, presenting a balancing technique involving the resection of the depressor labii inferioris on the non-affected side.
