Individuals in the sample were categorized according to sex, one of three growth stages, and one of three skeletal patterns. Differences in length between distances from the points at which ear rods were inserted to the facial midline and the perpendicular distance from the soft-tissue menton to the facial midline were measured on a frontal facial photograph. Subjects with a discrepancy of more than 3 standard deviations of the measurement error were categorized as having left- or right-sided laterality.<\/jats:p>\n               <jats:p>Results: Of subjects with facial asymmetry, 79.7% had a wider right hemiface, and 79.3% of those with chin deviation had left-sided laterality. These tendencies were independent of sex, age, or skeletal jaw relationships. In this regard, during pubertal growth, the proportion of subjects with wider right hemiface decreased (P &amp;lt; .0001), whereas the proportion of those with a wider left hemiface increased (P &amp;lt; .01), despite a consistent tendency for right-sided dominance.<\/jats:p>\n               <jats:p>Conclusion: These results suggest that laterality in the normal asymmetry of the face, which is consistently found in humans, is likely to be a hereditary rather than an acquired trait.<\/jats:p>","DOI":"10.2319\/022107-85.1","type":"journal-article","created":{"date-parts":[[2007,11,7]],"date-time":"2007-11-07T22:31:15Z","timestamp":1194474675000},"page":"421-426","source":"Crossref","is-referenced-by-count":140,"title":["Asymmetry of the Face in Orthodontic Patients"],"prefix":"10.2319","volume":"78","author":[{"given":"Seiji","family":"Haraguchi","sequence":"first","affiliation":[{"name":"a\u2009Assistant Professor, Department of Orthodontics and Dentofacial Orthopedics, Graduate School of Dentistry, Osaka University, Osaka, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoshitaka","family":"Iguchi","sequence":"first","affiliation":[{"name":"b\u2009Clinician, Department of Dentistry and Oral-Maxillofacial Surgery, NTT West Osaka Hospital, Osaka, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kenji","family":"Takada","sequence":"first","affiliation":[{"name":"c\u2009Professor and Chair, Department of Orthodontics and Dentofacial Orthopedics, Graduate School of Dentistry, Osaka University, Osaka, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1164","reference":[{"key":"2020042120435576700_i0003-3219-078-03-0421-b1","article-title":"Contemporary Orthodontics.","author":"Proffit"},{"key":"2020042120435576700_i0003-3219-078-03-0421-b2","first-page":"89","article-title":"Dental and facial asymmetries: a review.","volume":"64","author":"Bishara","year":"1994","journal-title":"Angle Orthod"},{"key":"2020042120435576700_i0003-3219-078-03-0421-b3","doi-asserted-by":"crossref","first-page":"191","DOI":"10.1016\/S0889-5406(94)70038-9","article-title":"Associations of mandibular and facial asymmetries: a review.","volume":"106","author":"Pirttiniemi","year":"1994","journal-title":"Am J Orthod Dentofacial Orthop"},{"key":"2020042120435576700_i0003-3219-078-03-0421-b4","doi-asserted-by":"crossref","first-page":"97","DOI":"10.1093\/ejo\/cji097","article-title":"A computerized photographic assessment of the relationship between skeletal discrepancy and mandibular outline asymmetry.","volume":"28","author":"Good","year":"2006","journal-title":"Eur J Orthod"},{"key":"2020042120435576700_i0003-3219-078-03-0421-b5","first-page":"141","article-title":"An assessment of asymmetry in the normal craniofacial complex.","volume":"48","author":"Shah","year":"1978","journal-title":"Angle Orthod"},{"key":"2020042120435576700_i0003-3219-078-03-0421-b6","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1093\/ejo\/1.1.1-a","article-title":"Growth of the soft tissues of middle third of the face between 9 and 16 years.","volume":"1","author":"Burke","year":"1979","journal-title":"Eur J Orthod"},{"key":"2020042120435576700_i0003-3219-078-03-0421-b7","doi-asserted-by":"crossref","first-page":"825","DOI":"10.1016\/0028-3932(81)90096-8","article-title":"Asymmetries for hemiface size and mobility.","volume":"19","author":"Koff","year":"1981","journal-title":"Neuropsychologia"},{"key":"2020042120435576700_i0003-3219-078-03-0421-b8","first-page":"70","article-title":"Facial asymmetry in healthy North American Caucasians.
