Abstract
Despite the improvement of primary repair of nasal deformities during the management of cleft lip in infancy, this does not exclude the need for revision rhinoplasty in adulthood for complete patients' rehabilitation. The purpose of this study was to evaluate the aesthetic outcome of secondary rhinoplasty using costal cartilage grafts in patients with unilateral cleft lip nasal deformity. Twenty patients who were operated at earlier ages for correction of cleft lip and had a residual unilateral cleft lip nasal deformity were included in this study. Costal cartilage rib grafts were harvested; carved and used for maxillary augmentation, columellar strut graft, and lateral crural strut graft. Five anthropometric measurements (nostril height, width and gap area, columellar axis deviation angle and nasal base inclination angle) were used for evaluation of aesthetic results. The ratio of nostril width, height and gap area between the cleft side and the non-cleft side showed significant improvement (P <0.05). The columellar axis deviation showed significant improvement towards the midline (P = 0.004), and the alar base inclination showed improvement towards the horizontal line (P = 0.0045). In conclusion, the aesthetic outcomes of secondary cleft lip rhinoplasty using the costal cartilage are satisfactory. The costal cartilage has the required strength, is easily carved and maintains shape for considerable time.
