comparison of suture and vertical dome division techniques of bulbous nose refinement

objective:in this study, we assess long-term effects of vertical dome division (v.d.d) and suture techniques in patients with bulbous nose deformity and then compare the efficiency of these methods. material and methods: in this study 70 patients with bulbous nose deformity were divided into two equal groups of a and b in which group a with suture (transdomal and interdomal) technique and group b with vdd technique underwent surgery to correct the deformity. results: among the 35 patients, two patients in group a (7.5%) have a previous bulbous nose deformity remained stable of whom one patient resulted in revision surgery. nasal tip over narrowing was not observed in this group. the overall satisfaction rate in this group of patients was approximately 92%. of 35 patients in group b, who underwent surgery using vdd method eight months after surgery in all patients widening of nasal tip was reduced, but another complication as over narrowing nasal tip was observed in three patients (6.8%) which in one case this led to revision surgery and in one case (2.8%) collapse of lower lateral cartilage (llc) occurred. the overall satisfaction rate in this group was approximately 86%. there was no significant difference regarding satisfaction rate between these two study groups. conclusion: there are no significant differences between these two methods’ results in terms of over- narrowing in nasal tip. in vdd method the dome can be narrowed to a higher level compared with suture technique. nondestructive methods such as suture both aesthetic and functional issue are little.
