For the correction of secondary cleft lip and nasal deformity, it is important to identify the reasons of deformation precisely. In this report, scar revision techniques, straight line repair and rotation-advancement flap, are described with appropriate cases for the correction of the unilateral secondary cleft lip nasal deformity. Additionally, these two techniques are presented with comparison of indications, functional outcomes and aesthetic results. A 15 year old boy who had a history of bilateral cleft lip repair was referred for the scar revision. Whistle lip deformity due to vertical scar contracture was found. However, nasal septum was not deviated and bilateral symmetry of the nostrils was preserved. Following excision of scar tissue, orbicularis oris muscle was rearranged functionally then separated lip was closed using straight line repair. The result was favorable and aesthetic reconstruction of the philtral ridge was possible postoperatively. However, excessive lip lengthening of the affected side was unsatisfactory, periodic follow-up is needed. A 34 year old man with cleft lip scar underwent scar contracture and skin depression as well as flattened nostril and deformed nasal ala. Following resection of the scar tissue according to the rotation-advancement flap technique, orbicularis oris musculature was rearranged. Each layer of mucosa, muscle, skin was sutured separately. The lip was lengthened sufficiently and symmetry of the nose was recovered postoperatively. Determination of the repair technique should be made by cause and extent of the deformity in secondary cleft lip nasal deformity. In this report, satisfactory revision of the scarred lip was possible using straight line repair or rotation-advancement flap technique as well as functional rearrangement of the orbicular oris muscle. The result was favorable aesthetically and functionally
