tetracycline and Cleft-Lip

Although harelip, cleft palate, or both, are by far the most common major facial malformations, the mechanisms underlying their embryogenesis are only now beginning to be understood; this is due to the complexity of primary and secondary palate development and the fact that appropriate methods for study have only recently been developed. The authors present a review of the most significant data regarding the etiology of hare lip and cleft palate, both in their physiopathogenic aspects and in their clinical morphology. The peculiarity of these malformations is outlined, supported by literature data and personal experimental experience.

Associations between drug consumption during pregnancy and the birth of children with oral clefts were studied in material from the Finnish Register of Congenital Malformations, consisting of 599 children with clefts and their matched controls. Information concerning maternal drug consumption was partly prospective. During the first trimester, analgesic, chemotherapeutic and antineurotic drugs had all been significantly more frequently used by the mothers of children with clefts, than by the control mothers. The consumption of drugs was in general more frequent among mothers of children with cleft lip, with or without cleft palate, than among those of children with cleft palate alone.
