Congenital absence or hypoplasia of facial muscles has not been known except for the depressor anguli oris muscle. Even, congenital unilateral hypoplasia of the orbicularis oris muscle cause of unilateral upper lip palsy has not been reported in the literature up to day. In this report, we present a patient with congenital unilateral upper lip palsy although the facial nerve was normal.展开更多
