title: [Oblique oval deformation of the upper dental arch and arciform deviation of the face in unilateral cleft lip].
abstract: Abnormal muscular equilibrium due to unilateral cleft-lip is responsable for deviation of the center of the face and of the outline of the upper lip towards the healthy side. This deviation is constant but is variable in intensity. By taking precautions in the neonate it can be attenuated, particularly by orientation of the bottle. The degree of perfection of muscular suturing in the region of the nasal threshold is the basis of reestablishment of early normal muscular equilibrium. The quality of the primary treatment decreases the degree of importance of facial sequelae but risks aggravating the contraction of the upper lip if not followed-up pre- and post-operatively with orthodontic treatment.
