In the cleft lip patients, several anatomical, functional and embryological deformities in mid-face are usually present. Among them, deformities of ala, septal cartilage and maxillary hypoplasia are more prominant according to its degree of deformity.
Up to date, there are many operative variations in successful correction of nasal deformity and hypoplastic maxillary pyriform in cleft patients.
During the past 4 years, form Jan., 1975, to Dec., 1978, we have observed 19 patients of secondary nasal deformity of cleft lip who had been treated with corrective rhinplasty and iliac free bone graft on depressed and hypoplastic pyriform area.
This paper reviews our experience of secondary nasal deformity in cleft patient and results are summarized as follows;
1) There were much more satisfactory appearance in patients who had been operated at adult age.
2) There was about 20% absorption in grafted bone within 1 year.
3) There was none of alteration of position in all grafted bone that were fixed with pyriform by making hook-like groove in bone fragment.
