Turner Syndrome (TS) is an x-linked genetic disorder occurring in females about 1 out of 2,000 live births. Symptoms of the Ts patients include short stature, premature ovarian failure and underdeveloped secondary sexual characteristics. Several medical problems occur more frequently in individuals with TS including cardiac or kidney abnormalities, hypothyroidism and otitis media. Other physical features that may come with TS patients are low-set ears, low hairline, webbed neck, short fourth metacarpals, strabismus and Scoliosis. Mandibular retrognathism is one of the symptoms seen in TS along with short extremities. Improper bone development before or at puberty has been blamed on growth and estrogen hormone deficiency. TS girls who are not treated with hormone replacement usually do not have a pubertal growth spurt. Lack of pubertal growth spurt in Ts patients propounded the idea that growth modification could improve the deficient mandible in TS patients even in their twenties because the growth continues slowly through the life and it might not be age-dependent. The aim of this paper is to present a seventeen-years -old female patient with TS whose severe deficient mandible successfully was advanced by twin block functional treatment and her many skeletal class II features were improved.
