Concept Unique Identifier (CUI): C0032209

Semantic Type: Congenital Abnormality

HPO Definition: Abnormal elevation of the floor of the posterior fossa including occipital condyles and foramen magnum. [HPO:probinson, pmid:10084535]

HPO Definition: A developmental malformation of the occipital bone and upper end of the cervical spine, in which the latter appears to have pushed the floor of the occipital bone upward such that there is an abnormal flattening of the skull base. [HPO:probinson]

MSH Definition: A developmental deformity of the occipital bone and upper end of the cervical spine, in which the latter appears to have pushed the floor of the occipital bone upward. (Dorland, 27th ed)

HPO_COMMENT Platybasia is malformation of the base of the skull due to softening of skull bones or a developmental anomaly, with bulging upwards of the floor of the posterior cranial fossa, upward displacement of the upper cervical vertebrae, and bony impingement on the brainstem. It results in abnormal obtuseness of the basal angle that can be demonstrated radiographically. If platybasia is associated with basilar invagination, compression of the brainstem and upper cervical cord can result.nBasal Angle formed by:nline joining the nasion with the centre of the pituitary fossanline joining the anterior border of the foramen magnum with the centre of the pituitary fossannormal: 125 degrees-143 degreesnplatybasia: > 143 degreesnbasilar kyphosis: < 125 degrees {xref="orcid.org/0000-0001-5889-4463"} HPO
