Complete Unilateral Cleft Lip Clinical Trial
Official title:
Unilateral Cleft Lip Closure - Development of a New Hybrid Technique
Unilateral cleft lips can be treated with different incision techniques. According to a survey by the American Cleft Palate Association, the Millard II technique is currently used by the majority of US cleft surgeons. In this technique, a cleft-sided advancement flap is pivoted from the cleft side into the rotation flap of the non-cleft side, which serves, among other things, to lengthen the lip. However, the rotational component is often insufficient to sufficiently lengthen the lip on the cleft side. The result is a raised red lip, a shortened edge of the philtrum or a so-called pipe-hole deformity. In order to compensate for these "deficiencies", a triangular flap is currently being formed in the area of the white roll, which is intended to provide sufficient lengthening. However, the scar of the triangular flaps runs exactly opposite to the aesthetic unit. In addition, it often provides a step formation within the white roll. Knowing the weaknesses of the previous techniques, a further development of the incision was made. The rotational flap of the Millard II technique was extended by extending the incision into the columella - similar to the well-known Mohler technique. The caudal part of the advancement flap of the Millard II technique was extended by a wave incision as known from the Pfeifer procedure.
