The secondary nasal deformity of cleft lip is the difficulty of cleft lip repair. Simple surgical treatment can't solve the complicated nasal deformity. In view of the above situation, different deformity repair operations are needed at different developmental stages of patients.

Generally speaking, the treatment opportunity of cleft lip and nasal deformity mainly considers three stages.

In the first stage, the patients can correct the nasal deformity at the same time when they repair unilateral cleft lip in infancy (3 months to 1 year), and adopt simple minimally invasive methods to make it develop in a better direction, which provides better conditions for obtaining satisfactory nasal shape and later repair.

In the second stage, patients aged 9~ 1 1 year were treated with orthodontic treatment, alveolar cleft bone grafting and subgalar bone grafting. Bone grafting is for better development in the future, and there is a hard main support at the same time.

The third stage is 14 years old to 16 years old. Because the patient's development is basically mature and the alar cartilage is dense and elastic, a more thorough and comprehensive rhinoplasty operation is needed to achieve a normal nose shape to the greatest extent. With the development of rhinoplasty technology, the treatment of cleft lip nasal deformity has been promoted, and many rhinoplasty technologies and concepts have been applied to the treatment of nasal deformity.
