dysostosis /dys·os·to·sis/ (dis″os-to´sis) defective ossification; defect in the normal ossification of fetal cartilages.

cleidocranial dysostosis  a hereditary condition marked by defective ossification of the cranial bones, absence of the clavicles, and dental and vertebral anomalies.

craniofacial dysostosis  a hereditary condition marked by acrocephaly, exophthalmos, hypertelorism, strabismus, parrot-beaked nose, and hypoplastic maxilla.

mandibulofacial dysostosis  a hereditary disorder occurring in a complete form (Franceschetti syndrome) and a less severe form (Treacher Collins syndrome), with antimongoloid slant of the palpebral fissures, coloboma of the lower lid, micrognathia and hypoplasia of the zygomatic arches, and microtia.

metaphyseal dysostosis  a skeletal abnormality in which the epiphyses are normal and the metaphyseal tissues are replaced by masses of cartilage, producing interference with enchondral bone formation.

dysostosis mul´tiplex  Hurler's syndrome.

orodigitofacial dysostosis  orofaciodigital syndrome.

Etymology: Gk, kranion + L, facies, face; Gk, dys, bad, osteon, bone

an abnormal hereditary condition characterized by acrocephaly, exophthalmos, hypertelorism, strabismus, parrot-beaked nose, and hypoplastic maxilla with relative mandibular prognathism. This condition is transmitted as an autosomal-dominant trait. See also dysostosis.
