“…Facial asymmetry in those patients should be carefully assessed during GH treatment. Further studies are necessary to establish a proper dose for improvement of mandibular growth in class II patients and to assess for possible side effects of therapy [2]. Hwang and Cha described a case of a short-statured girl treated with GH during orthodontic treatment.…”

“…However, if the treatment has been commenced after all, it should be taken under consideration that GH replacement therapy affects mandibular growth more than it affects development of maxilla. Also, both the pattern as well as the degree of growth during GH therapy is difficult to predict and GH rarely affects maturation of teeth [2,46,47].…”

“…Later, larger groups of children with GHD were analyzed for changes in dentition and craniofacial morphology-delayed development of teeth, face, and cranial base were described [1]. Although little is known about the mechanism of action of growth hormone (GH) on craniofacial components, it is believed that therapy with recombinant human growth hormone (rHGH) acts mainly on those craniofacial parts where epiphyseal ossification takes place and on the areas that adapt to this growth-mandibular rami in particular [2]. GH is a peptide hormone excreted by somatotropic cells of the anterior pituitary under control of hypothalamic hormones and ghrelin, as well as other substances produced in the central nervous system [3].…”

The review aims to collect and demonstrate recent knowledge about craniofacial morphology in growth hormone (GH)-deficient children and children with Turner syndrome. The review describes also the effects of growth hormone treatment on craniofacial morphology of children with growth hormone deficiency and Turner syndrome. Regardless of the disorder it accompanies, short stature is associated with similar craniofacial features characteristic of all short-statured children. Characteristic craniofacial features involve lesser dimensions of the cranial base and mandibular length, proportionately smaller posterior than anterior facial height, retrognathic face, and posterior rotation of the mandible. We also analyze orthodontic treatment in children affected by disorders associated with GH deficiency or provided with growth hormone treatment in the aspect of craniofacial growth. Recent publications show also the connection between growth hormone receptor polymorphism and craniofacial growth. Specialists and orthodontists treating short-statured children must be aware of the results of studies on craniofacial morphology and educate themselves on the topic of craniofacial growth in children with short stature. Moreover, knowledge of the influence of GH therapy on growth of craniofacial structures is necessary to decide the proper timing and planning of orthodontic treatment.

“…Rabie et al 20 and Jung 21 have associated the changes in the glenoid fossa to changes occurring at the cellular level. They found that mandibular protrusion resulted in osteoprogenitor cells being oriented in the direction of pull of posterior fibers of articular disc and also resulted in a considerable increase in bone formation in the glenoid fossa.…”

This study was conducted to evaluate skeletal changes in glenoid fossa, condylar head and articular space following Powerscope appliance therapy using CBCT.This study included twenty patients (age group of 11-15 years) having Class II Division 1 skeletal & dental malocclusion. A pre-treatment CBCT scan (T1) of both TMJs was taken. Following leveling & aligning, Powerscope appliance was inserted, which was sequentially activated using crimpable shims until edge-to-edge bite was obtained. After completion of phase 1 of treatment, another CBCT scan (T2) was taken. Condylar position, length, height, glenoid fossa & articular space measurements were obtained from pre- & post-treatment CBCT scans and data obtained were statistically analysed and compared by Paired-t test.Comparison between T1 & T2 data showed that the condyles were shifted anteriorly by 1.08 mm, condylar length and height increased by 0.26 mm and 0.71 mm, respectively. Glenoid fossa and anterior articular space decreased by 1.50⁰ and 0.23 mm, whereas, middle and posterior articular spaces increased linearly by 2.55 mm and 1.85 mm, respectively.Powerscope shifted the condyle anteriorly, increased its length and height, and reduced the glenoid fossa angle. Anterior articular space decreased whereas middle and posterior articular spaces increased.
