RESUMEN
BACKGROUND: To introduce an innovative refinement, the "double V cutting folded derotation graft" (DVCFD graft), which is a method for nasal tip lengthening in aesthetic rhinoplasty with strong holding force and efficient cartilage use. METHODS: A retrospective study was conducted from January 2018 to July 2019 with 101 patients, including 11 males and 90 females with an average age of 36.87 ± 10.12 years, at Chang Gung Memorial Hospital; the patients received classic derotation grafts (n = 49, 17 of them were one layer and 32 of them were two layers) and DVCFD grafts (n = 52) for cosmetic tip plasty. The tip projection, columella labial angle and nasolabial angle were measured through clinical photography at three different times (T0: pre-operation, T1: two weeks post-operation and T2: five months post-operation). The differences between the original derotation graft and the DVCFD graft were identified using paired-t and independent-t tests. RESULTS: The final relapse ratios of the classic derotation graft and DVCFD graft were 36.78% versus 36.92% for tip projection, 40.65% versus 38.58% for columella labial angle and 45.00% versus 47.76% for nasal labial angle, respectively. The P values of the independent-t tests were 0.991, 0.564 and 0.439, respectively. CONCLUSIONS: Both the classic derotation graft and DVCFD graft possess similar stability in tip plasty. The novel modification of the DVCFD graft has more efficient cartilage usage and is a feasible and safe surgical option for patients with limited harvestable cartilage for tip lengthening.

PURPOSE: Although facial nerve palsy is uncommon after a blunt craniofacial injury, it will result in functional and aesthetic disability if full recovery is not achieved. Currently, the management is still controversial and mainly through systemic steroid therapy or surgical decompression. However, current studies mainly focus on the surgical intervention, and only a few of these studies discuss the details of the steroid treatments. Thus, the purpose of this study is to analyze possible prognosis factors of systemic steroid in managing traumatic facial nerve palsy after a blunt craniofacial injury retrospectively. METHODS: During the period from May 2005 to April 2015 at Chang Gung Memorial Hospital, a total of 26 patients who suffered from post-traumatic facial nerve palsy receiving steroid therapy were enrolled in the study. All the patient's charts were reviewed, recorded, and analyzed including the general data, temporal bone fracture type, hospital courses, trauma-related data from emergency room records, and initial and final facial nerve palsy grading. The facial nerve palsy was graded using the House-Brackmann (HB) system; the final HB grade I was set as full recovery. RESULTS: The outcome showed steroid therapy onset within 24âhours (odds ratio [OR]â=â10.111; 95% confidence interval [CI]â=â1.597-64.005; Pâ=â0.014) and steroid therapeutic duration for longer than 14 days (ORâ=â11.571; 95% CIâ=â1.172-114.262; Pâ=â0.036) possessed a significantly better recovery rate. CONCLUSION: This study recommends to apply steroids within 24âhours once post-traumatic facial palsy occurs and the therapy should persist longer than 14 days.
