skull deformation; cranial deformation
Medical term referring to abnormal shape of the skull, either congenital or acquired.
Skull deformation can occur due to fetal compression or genetic factors.
In this case, cranial deformation was clearly observed.
Compound of 頭蓋 (とうがい, 'skull') and 変形 (へんけい, 'deformation'). The exact historical derivation is uncertain; the spelling is conventionally associated with the medical meaning.
