Background: A few studies have been published on the clinical efficacy and safety of nasal tip defatting plus rhinoplasty, particularly among people with bulbous noses. Therefore, the present study aimed to assess the consequences of nasal tip defatting for skin thickness reduction.
   Methods: This quasi-experimental study was performed on 72 consecutive patients, candidates for aesthetic rhinoplasty. Twenty-seven patients were scheduled for nasal tip defatting with routine open rhinoplasty concomitantly. Besides, 45 patients underwent rhinoplasty without nasal tip defatting method. Tip and supra-tip skin thickness were assessed before and 12 months after the operation using ultrasonography. The patients' and surgeon's satisfaction with aesthetic results after the operation were also evaluated based on visual analog scaling (VAS). SPSS version 16.0 (SPSS Inc., Chicago, IL., USA) was used for the analyses. P values below 0.05 were considered statistically significant.
   Results: Seventy-two patients (4 men, 68 women; mean age 26.40 ± 4.61 years) entered the study. Twenty-seven candidates underwent rhinoplasty plus nasal tip defatting (group A). Open rhinoplasty alone was performed for the other 45 patients (group B). The mean nasal tip thickness was 3.98±0.84 mm in group A and 3.69±0.64 mm in group B before the surgery (p=0.059). Preoperative nasal supra-tip thickness of the patients was also assessed using ultrasonography (3.54±0.72 mm in group A versus 3.73±0.54 mm in group B; p=0.065). Both preoperative tip and supra-tip thickness did not statistically differ between the two groups. No significant difference in postoperative tip skin thickness was obtained between two groups after 12 months (3.24±1 mm in group A versus 3.25±0.625 mm in group B; p=0.960), while postoperative supra-tip skin thickness differed significantly according to ultrasonography assessments (2.86±0.60 mm in group A versus 3.25±0.71 mm in group B; p=0.016). Postoperative satisfaction of the candidates was obtained using theVAS scoring system 12 months after the operation in both groups (8±1 in group A, 7.5±1 in group B; p=0.021). Surgeon’s satisfaction in terms of the aesthetic outcome was also assessed based on the VAS system which did not statistically differ between the two groups as well as the patients’ satisfaction (7.84±1.42 in group A, 7±1.61 in group B; p=0.014).
   Conclusion: Nasal tip skin defatting is the main component in aesthetic rhinoplasty, but its significant effect on the reduction of tip skin thickness is controversial. However, in patients with moderate or thick nasal tip skin, such a procedure can result in higher postoperative satisfaction with the aesthetic outcome compared to rhinoplasty alone.
