The aim of this retrospective study was to investigate the long-term outcome of the procedure in a large cohort of 68 cases. In total, 58 patients with 68 full thickness scalp defects with exposed skull bone, were included. Mean follow-up time was 24 (±19) months. The mean size of the defects was 63 (±54) cm2. During the follow-up period, no local recurrences occurred. Complications were observed in 13% of the cases including template necrosis (4%), infections (4%), ulcerations (3%), and autograft necrosis (2%). During the final follow-up, 26 patients had died due to internal diseases not associated with the surgery. Cosmetic results were rated good by the patients and an independent observer. The use of a dermal regeneration template for the reconstruction of large, full thickness defects of the scalp with exposed skull bone is a reliable method regarding the complication rate, safety of the procedure, and cosmetic outcome. Limitations of this study are the retrospective and single center design.

Fractional microneedle radiofrequency (FMR) and nonablative 1927-nm fractional thulium fiber laser (TFL) are widely used for skin rejuvenation treatment. To investigate the efficacy and safety of combined treatment with both devices for wrinkles. Twenty-five patients with wrinkles were enrolled. One side of the face was treated with FMR alone, while the other side was treated with a combination of FMR and TFL. Each treatment consisted
