| Abstract: | Refinements in the triangular flap closure of the unilateral cleft lip are presented. Randall's mathematical interpretation of the Tennison repair has been extended by using a series of arcs to determine the crucial points which form the triangular flap. Using this easily taught method, an isosceles triangular flap can be plotted which will interdigitate into the noncleft side of the lip. Two symmetrical vertical distances on either side of the cleft are thus formed. This allows for a standardized repair which may be more readily taught than the rotation-advancement technique. In addition, flaps are created which are turned medically toward the cleft and are used to accentuate the philtral pout, close the nostril floor, and reinforce the lip repair, allowing closure of even extremely wide clefts in one stage. These refinements in using the triangular flap closure for the repair of the unilateral cleft lip are diagrammatically presented. We believe that these refinements enhance the results of this closure. |
