The Djo technique: A novel technique for unilateral cleft lip

Abstract

In unilateral cleft lip, elevation of the cleft side of the philtrum follows the elevation of the whole philtrum, beginning from the point where the philtral ridge of the normal side meets the vermilion. To inferiorly rotate this segment of the lip, the incision line must pass through the entire width of the philtrum. If the incision is limited only partially across the philtrum, anatomical correction will not be achieved. Here, the Djo technique for unilateral cleft lips is introduced. This technique is based on the accurate measurement of lip deficiency on the affected side. A triangular flap was created to fill the gap and correct the deficit.The design is made by marking points A, B and C on the white roll where the philtrum meets the vermillion. D and E are points where the philtrum ridges meet the nasal sills. To achieve downward rotation of point C to the level of point A, line m is made from D to F at the philtrum ridge of the normal side. After incision, a triangular gap is produced. This gap will be filled by triangular isosceles flap the cleft side of the lip.During the first week of healing process, the white skin roll was in a symmetrical line and the lip was not retracted. All the patients demonstrated a good result.The main advantage of the Djo Technique is its design, where the points and lines on the part to be incised have been measured with an accurate calculation.
