Abstract |
: |
Noonan syndrome and Turner syndrome are characterized by similar phenotypes, mainly, short stature, low
birth weight, triangular face, prominent ears and webbed neck. This study clinically and radiographic ally documented
and compared the oro-dental and craniofacial manifestations in both syndromes to assess the important
differences and similarities that might be of diagnostic value. Three groups were included for comparison, group
I consisted of 10 normal control females, group II consisted of 10 cases of Noonan syndrome, group III consisted
of 10 cases of Turner syndrome. All cases were subjected to pedigree analysis, clinical examination, cytogenetic
findings, clinical photographs, lateral and postero-anterior cephalograms and panoramic radiographs.
The results were subjected to statistical analysis of variance (ANOVA) which showed that the
similarities in both syndromes were high arched palate, thick lips, cro\yn and root formation abnormalities,
malocclusion, mandibular retrognathia, shortened posterior cranial base length and both maxillary length and
width' Apparent hypertelorism was due to soft tissue telecanthus not a true bony hypertelorism. Noonan syndrome
differed in the presence of tongue anomalies, increased mandibular downward tipping and vertical jaw dimension;
shortened anterior cranial base length, mandibular width and effective mandibular length. Turner syndrome
patients showed wide maxillary sinus, maxilla_ryretrognathia and increased labio-inclination of lower
central incisors to their apical base. |
