Assessment of nostril symmetry after primary cleft rhinoplasty in patients with complete unilateral cleft lip and palate

Abstract

The aim of this study was to assess the nostril symmetry following primary cleft rhinoplasty done with either a dorsal onlay or columellar strut graft in patients with non-syndromic complete unilateral cleft lip and palate. In this retrospective study 30 consecutive patients treated with autogenous or alloplastic dorsal onlay grafts and 30 consecutive patients treated with autogenous or alloplastic columellar strut grafts for complete unilateral cleft nose reconstruction were analyzed for nasal symmetry. The autogenous grafts used were costo-chondral or septal cartilage and the alloplastic graft used was high density polyethylene (Medpore(®)). Assessment of the nostril symmetry was done using a two-dimensional nasal analysis 24-30 months postoperatively. Ratios between cleft and noncleft side nostril for three parameters were used to assess symmetry namely nostril width, nostril height and nostril gap area. None of the three parameters showed statistically significant changes. A satisfactory, though not statistically significant, difference in symmetrical outcome could be achieved in both the groups with the exception of nostril width symmetry in group treated with dorsal onlay graft.
