The width of the mouth varies with facial movement and must be assessed when the subject has a relaxed (neutral) face. This term replaces macrostomia, large mouth, and large oral aperture because these terms imply a wide and open mouth. The term should not be used to describe a patient with a lateral oral cleft.
