FREUNDLICH, Tomás; ARUESTE, David; MANRIQUEZ, Germán  and  DIAZ, Alejandro. Cephalometric comparison between an acromegalic patient and his twin brother. Odontoestomatología [online]. 2019, vol.21, n.33, pp.81-88.  Epub June 01, 2019. ISSN 0797-0374.  https://doi.org/10.22592/ode2019n33a10.

Acromegaly is characterized by a slowly progressive somatic disfigurement caused by the overproduction of growth hormone (GH) and insulin-like growth factor 1 (IGF 1), mainly associated with a pituitary adenoma. The most evident facial manifestation is mandibular prognathism due to excessive growth of the jaw. This work aimed to perform a craniofacial morphological comparison through cephalometric analysis and cephalometric superimposition of a patient diagnosed with acromegaly and his twin brother without the disease. Our results showed that the acromegalic patient has a significant increase in the size of the sella turcica, an anterior displacement of the maxilla and mandible, the mandibular displacement being more marked. The morphological change of the mandible in acromegaly is mainly attributed to the growth of the mandibular ramus due to an increase in the condylar unit.

Keywords : acromegaly; twins; cephalometry; mandibular condyle.
