The naso-ocular cleft is a rare defect; however, isolated alar clefts with or without additional hamartomatous local tissue are an even rarer problem. The authors describe six unilateral and one bilateral cleft patients who were all initially repaired using the same operative procedure. The concept of this procedure is based on the principle that there is basically no soft-tissue deficiency but rather a malpositioning of the parts. The leading edge of the ala is re-created by a rotation advancement of both the medial and the lateral segments adjacent to the cleft. The created secondary defect is filled with a paranasal transposition flap. Three of our patients had hamartomatous excesses and were the most difficult to balance, and at the same time, two of these patients required subsequent bridging or augmentation using a free conchal cartilage graft. Examples of the operative procedures are outlined both schematically and clinically. |
