“…Craniofacial microsomia (CFM) is a congenital deformity of the head and face, occurring second most commonly after cleft lip and palate 1,2 . The incidence of CFM is reported to be 1/3000–5600 2–5 . There are a variety of terms applied to CFM, including Goldenhar syndrome, first and second pharyngeal arch syndrome, hemifacial microsomia and oculoauriculovertebral dysplasia 6 .…”

ObjectiveTo describe the mandibular growth of craniofacial microsomia (CFM) patients during early childhood to adolescence with attention to symmetry.Materials and MethodsAltogether 61 CFM patients were studied at the Cleft Palate and Craniofacial Center, Helsinki University Hospital between 1986 and 2006. In this cohort study, we measured and analysed 293 radiographs (posteroanterior, panoramic and lateral); 165 radiographs of 40 patients met the final inclusion criteria. The vertical height of the ramus in anteroposterior and panoramic radiographs, the length of the mandible in anteroposterior radiographs and the maxillary protrusion and mandibular retrognathia in lateral cephalograms were measured in four different age groups.ResultsA statistical difference existed between the groups in the vertical height of the ramus and in the mandibular length. The vertical height of the ramus measured from the panoramic radiograph grew on both sides, and the ratios remained unchanged. In the sagittal dimension, the maxilla and mandible grew forward, but no significant differences emerged between the groups.ConclusionsResults suggest that mild‐type CFM is not progressive in nature. During growth, mandibular asymmetry measured in the horizontal, vertical and sagittal planes did not increase.

“…Examples include hemifacial microsomia or Goldenhar syndrome, the latter being considered a more pronounced variant of the former [8][9][10]22]. At a reported incidence of 1/5000, OAVS is one of the most widespread congenital facial anomalies, second in frequency only to cleft lip and palate, and with a men-to-women ratio of 3:2 [4,11,36]. Various hypotheses have been discussed regarding the etiopathogenesis of OAVS.…”

“…Nonrandom laterality is seen in the human brain, face, heart, great vessels, lungs, liver, gallbladder, biliary tract, gastrointestinal tract, spleen, and male genitalia. 3,4 All but 0.01% of humans exhibit the same asymmetric arrangement of their internal organs (situs or situs solitus). 5,6 Nevertheless, in extremely rare instances, the standard body plan is inexplicably altered.…”

Ten percent of people are left handed, but a higher frequency has been associated with certain craniofacial malformations, such as cleft lip and unilateral coronal synostosis. The purpose of this study was to determine the frequency of left-handedness in patients with hemifacial microsomia (HFM). Patients with HFM were identified in our craniofacial database. Normal controls were recruited by local pediatricians. Data gathered included age, sex, and handedness (determined by writing and/or drawing); the orbit, mandible, ear, nerve, and soft tissue (OMENS)-plus score and side of involvement were tabulated for patients with HFM. Hand preference was compared between the groups using chi analysis; possible correlations were analyzed between handedness and age, sex, the OMENS score, extracraniofacial findings, and side of involvement. One hundred seventy-eight patients with HFM were identified; 92 (51%) were excluded. Of the 86 included, 48% were boys (n = 47) and the mean age at inquiry was 13.5 years. Predominant side of involvement was right in 49% (n = 42) and left in 38% (n = 33). Eleven patients (13%) had severe involvement of both sides. Expanded-spectrum HFM was documented in 41% of patients. Ninety-six children were in the control group; 44% were boys (n = 42), and the mean age was 10 years. The difference in age between the groups was significant (P < 0.05), but sex differences were not. Patients with HFM were more likely to be left handed for writing compared with the control group (26% vs. 11%; P < 0.05). The frequency was higher, 36%, in those with bilateral involvement (P > 0.05). There was no correlation with predominant side or OMENS score. This study confirms that this disorder affects cerebral lateralization.
