Objective To investigate a new method which could not only avoid the extrusion of the silicon implant, but also be benefit for the reconstruction of nasal tip and alar during nasal augmen-tation procedure. Methods Folded lower lateral cartilage flap combined with silicon implant was ap-plied for nasal dorsal augmentation and reconstruction of nasal tip and alar with its unique character at the same time. Results 12 cases were all primary healing, without infection, extrusion of implant and other complications. One month after operation, the projection of nasal tip was increased, which had better delicate and definite shape, natural appearing tip adding contour and height to nasal tip, pleas-ant definition. Conclusions Folded lower lateral cartilage flap combined with silicon implant is an ef-fective method to decrease the incidence of extrusion, when we want to have a little over-projected na-sal tip with prosthesis. It is also helpful for reconstructing the nasal tip and alar with its unique char-acter.

Objective:To compare the efficacy and safety of oral terbinafine versus itraconazole in the treatment of pediatric tinea capitis.Methods:From January 2021 to December 2021, a randomized clinical trial was conducted among 53 children with tinea capitis in Beijing Children′s Hospital. These patients were randomly divided into 2 groups by using a random number table: terbinafine group treated with oral terbinafine at different doses (weight <20 kg, dose: 62.5 mg/d; weight 20 - 40 kg, dose: 125 mg/d; weight >40 kg, dose: 250 mg/d), while itraconazole group treated with oral itraconazole at doses of 3 - 5 mg·kg -1·d -1. Statistical analysis was performed using the SPSS 23.0 software, and enumeration data were compared between groups by using chi-square test or Fisher′s exact test. Results:Totally, 27 patients were treated with oral terbinafine, including 17 with tinea alba and 10 with kerion; 26 were treated with oral itraconazole, including 17 with tinea alba and 9 with kerion. After treatment, 14 (51.85%) patients were cured in the terbinafine group, including 5 with tinea alba and 9 with kerion, while 25 (96.15%) were cured in the itraconazole group, including 16 with tinea alba and 9 with kerion. The response rate was significantly higher in the itraconazole group than in the terbinafine group ( χ2 = 13.37, P < 0.001) . Conclusion:The efficacy of itraconazole was superior to that of terbinafine in the treatment of pediatric tinea alba, but their efficacy was equivalent in the treatment of pediatric kerion.
