Hopkins in 1861 was the first one to describe Prader-Willi syndrome, followed by Down in 1865. In 1956 Prader, Labhart and Willi described a hereditary form of obesity. This syndrome is a rare hereditary multi-systemic disorder.

Aim

The aim of the paper was to present a case of a 13-year-old female patient with Prader-Willi syndrome treated at the Department of Orthodontics, Medical University of Warsaw.

Case report

On admission a clinical examination was performed and medical history was taken. The following general symptoms were observed: facial dysmorphia, scoliosis, hypopigmentation, hypogonadism, hypersensitivity to light and sounds, and problems with thermoregulation. The patient was eligible for orthodontic treatment because she was diagnosed with a malocclusion.

Conclusions

Patient’s multispeciality treatment plays a key role in treatment of Prader-Willi syndrome, and it should include: paediatric, endocrine, psychiatric treatment, muscle rehabilitation and orthodontic treatment, and with an early and appropriate diagnosis such management may bring extremely favourable outcomes.
