Free dermis-fat graft to correct the whistle deformity in patients with cleft lip.

Vermilion notching or 'whistle deformity' is a common secondary deformity of the vermilion in patients with cleft lip. The free border of the lip is a composite structure consisting of the orbicularis oris and the overlying tissues, namely subcutaneous fat, vermilion and mucosa. A deficiency of all or one of these structures is responsible for the vermilion notch. An absolute shortage of the muscle or subcutaneous tissue necessitates the use of tissue from another source to correct the deformity. Dermis fat grafts have been used to augment the free border of the lip and correct this deformity. The technique is simple and reliable. The tissue is available in plenty, easy to harvest and could be repeated if necessary, i.e. in case of resorption. From June 1996 until January 2000 the technique was used in 10 patients. Of these 10, one was a bilateral cleft and nine were unilateral cleft lip deformities. A degree of graft resorption was seen in one patient, one had a partial graft loss due to ulceration and exposure. The first patient had a further augmentation.
