Conclusion
SJS is a rare genetic syndrome
with only a few reports of oral findings in the literature. The patient
presented with typical features of SJS includes myotonia, short
structure, abnormal gait, mask-like facie, blepharophimosis,
microstomia, retrognathia and pursed lip. In addition, he was also
diagnosed with a severe Obstructive Sleep Apnea which affected his daily
activities and quality of life. We reported his oral findings that
included severe dental crowding and narrow maxillary and mandibular
arches. This is also the first study describing detailed craniofacial
characteristics of a patient with SJS. The clinical findings of this
patient suggest that SJS could have effects not only on general but also
on craniofacial skeletons. And myotonia of craniofacial muscles could
results in a diminished maxillomandibular development. Since maxillary
and mandibular hypoplasia is a risk factor for pediatric OSA. patients
with SJS could be at risk to develop OSA as the patient in this report.
