Philtrum creation in secondary unilateral cleft lip repair.

A new method to create a philtrum in patients with unilateral cleft lip is presented. This modification was primarily used in secondary repair but can also be used in some primary repair cases. The results were satisfactory in most of the patients, at least at 2 years postoperatively.

Cleft Lip↗

Experimental study on cleft lip and/or palate: fetuses of A/J mice in uteri of F1 hybrid mothers using ovarian transplantation.

The A/J inbred strain of mice spontaneously develops cleft lip and/or palate (CL/P). Ovarian transplantation and several test-matings with C57BL/6 strain mice (0% CL/P) were performed to investigate a relationship between mother and fetus in regard to this order. The fetuses obtained showed that regardless of whether the genetic background of the mother was A/J or F1, CL/P was produced only in cases where the fetuses were genetically pure A/J. CL/P frequency was 7.46% in A/J fetuses developed in A/J mothers; it was 5.88% in F1 mothers with transplanted A/J ovaries. Isolated cleft palate (CP) and cleft lip with cleft palate (CLP) were found in A/J mothers. However, the frequency of CP was lower in F1 mothers than in A/J mothers. These results suggest that the occurrence of CLP depends more on the genetic constitution of the fetus than on maternal environmental factors, and the occurrence of CP was influenced by the mother's condition.

Oblique facial cleft, cleft palate, and supernumerary teeth secondary to amniotic bands.

A case of oblique facial cleft with supernumerary deciduous molars, probably caused by amniotic bands is reported. Besides facial cleft, and cleft palate and lip, there are sulci on the left side of the face and on the left posterior alveolar ridge. The sulci may be impressions of amniotic bands at a late gestational age and supernumerary teeth may also be related to these amniotic bands.
