Primary repair of the unilateral cleft lip nose in the Oriental: a 20-year follow-up.

The unilateral cleft lip nasal deformity is corrected as a primary procedure with the lip repair. The abnormal attachment of the alar base is first released by an incision along the superior buccal sulcus and piriform margin. There is no intercartilaginous incision. Basically, we use the Brown-McDowell technique with the addition of an alar rim incision. Undermining of the ala between the two incisions is carefully and adequately done, splitting it into two layers. The first is a skin and the second, a chondrocutaneous (vestibular skin) layer, which is handled as a single unit, thus enhancing its vascularity. This second layer is a bipedicle flap with a broad medial pedicle and a narrow lateral pedicle at the alar base. When the alar base is rolled into its normal position, the chondrocutaneous unit hinging on its two pedicles counterrotates, correcting the subluxation of the ala, a major component of the cleft lip nasal deformity. We depend on the normal position of the alar base, the postoperative scar tissue, and the inherently thick nostril wall in the Oriental to keep the alar dome up. No transfixion sutures are used. Ten consecutive patients are shown 20 years after surgery. All had one operation only. None showed any disturbance of nasal growth.
