Patients with a thick nasal skin and soft tissue envelope can have unpredictable results and irregular scarring after rhinoplasty surgery. These patients typically have sebaceous tissue over the nasal tip and are particularly susceptible to soft tissue polly beak formation and excess scar tissue in the radix, tip, and septum. Targeted injections of 5-fluorouracil alone or mixed with low concentrations of steroid can be useful to prevent and treat excess postoperative scar tissue deposition. Ideally, four to six injections are performed every 1 to 4 weeks beginning 1 week postoperatively. The injections are most beneficial when performed within the first 3 months after surgery. Even a single injection may improve outcomes with minimal side effects.
鼻皮肤和软组织包膜较厚的患者在隆鼻手术后可能会出现不可预测的结果和不规则瘢痕形成。这些患者鼻尖通常有皮脂腺组织,特别容易出现软组织“鹦鹉嘴”畸形以及鼻根、鼻尖和鼻中隔处过多的瘢痕组织。单独注射5-氟尿嘧啶或与低浓度类固醇混合注射,有助于预防和治疗术后过多的瘢痕组织沉积。理想情况下,术后1周开始,每1至4周进行4至6次注射。在手术后的前3个月内进行注射最为有益。即使单次注射也可能改善效果,且副作用最小。
