Abstract: We performed a literature review focusing on advances in the rhinoplasty of unilateral cleft nasal deformity. The nasal deformity of unilateral cleft lip can be manifested as nasal base collapse, tip deviation, columella shortening and deviation, septal deviation, alar collapse, bilateral nostril asymmetry, etc. Timing of rhinoplasty can be divided into primary,intermediate and definitive surgery. It is accepted that the final operation should be carried out in mature stage, while timely and early adjustment is conducive to the later correction effect. Treatment concept mainly focuses on structural remodeling and biomechanical reconstruction of nasolabial muscle tension system,which aims to guarantee long-term nasal symmetry and aesthetics. Detailed treatment contains flap transfer, biomechanical muscle reconstruction, graft material filling(autologous cartilage, biomaterials and artificial bone included) and osteotomy used for severe cases. Present surgical plan is individualized according to the characteristics of nasal deformities, which often combines multiple areas and methods. This article summarizes treatment concepts and therapeutic methods of unilateral cleft nasal deformity aiming to provide useful guidance for the selection and improvement of surgical trails.
