Normal noncleft subjects were included in Group I. Based on the severity of sagittal maxillary growth hypoplasia, subjects with UCLP were divided into two groups. Subjects with UCLP in whom the SNM angle was \u226571 degrees and the M-point to Nasion perpendicular distance was \u2264\u221210\u00a0mm were included in Group II. Group III consisted of subjects with UCLP in whom the SNM angle was &lt;71 degrees and the M-point to Nasion perpendicular distance was &gt;\u221210\u00a0mm. The mandibular asymmetry index (condylar, ramal, and condylar+ramal), gonial angle, and depth of the antigonial notch of three groups of subjects were examined on orthopantomograms (OPGs).<\/jats:p>\n        <\/jats:sec>\n        <jats:sec>\n          <jats:title>Results:<\/jats:title>\n          <jats:p>Among Group II subjects in whom sagittal maxillary growth was near normal, ramal and condylar+ramal heights were significantly less on the cleft side than on the normal side (<jats:italic>P<\/jats:italic> &lt; .01).
