Historical document, translated for reference. It reflects medical knowledge of the 1920s–30s and is not medical advice.
Summary
Gnathoschisis is a congenital deformity characterized by the failure of fusion between the unpaired intermaxillary process and one or both maxillary processes, resulting in a cleft of the upper jaw's alveolar process. This condition typically occurs in combination with cheiloschisis, contributing to the formation of a so-called harelip.
