OBJECTIVES/HYPOTHESIS: Nasal skin thickness has an important role in aesthetic results of rhinoplasty. The aim of this study was to evaluate the long-term results of tip and supratip skin defatting technique in rhinoplasty subjects using ultrasonography. STUDY DESIGN: Prospective, randomized, case-control study. METHODS: Among 111 rhinoplasty cases referred to a university hospital between February 2010 and September 2011, after physical examination and measuring the nasal tip and supratip skin thickness by ultrasonography, a total of 55 patients with thick and moderate skin were randomly allocated for rhinoplasty using one of the following methods: rhinoplasty with (case group) and without (control group) defatting tip and supratip skin. Ultrasonographic evaluation of the skins was repeated 1 and 12 months after surgery, and the data were analyzed by Wilcoxon and repeated measure tests using SPSS 17 software. RESULTS:Twenty-eight of 55 candidates (10 men, 45 women; mean age, 25.1 ± 7.6 years) underwent skin defatting during rhinoplasty; the other 27 patients did not undergo this procedure. Forty-four patients completed the study. Thickness of tip and supratip skin was not statistically different before surgery and during follow-up evaluations in defatting and nondefatting technique groups (P = .7). CONCLUSIONS: Defatting techniques have no effect on reducing tip and supratip skin thickness after rhinoplasty in moderate to thick skins.
