INTRODUCTION: Despite all the existing therapeutic tools, melasma continues to be a dermatological challenge. Therefore, the search for new treatment modalities aims to optimize results and reduce systemic side effects.
OBJECTIVE: Evaluate the clinical improvement of patients with melasma treated with robotic micro-needling associated to drug delivery of tranexamic acid.
MATERIAL AND METHODS: Seventeen women with melasma were selected to be treated during eight weeks with four fortnightly sessions of robotic microneedling associated to drug delivery of 1.0ml of 4mg/ml tranexamic acid. The group was evaluated before and after the treatment with the following parameters: photographic evolution evaluated by three examiners, self-evaluation with Melasma QoL and MASI improvement.
RESULTS: Fifteen Fitzpatrick phototype II to VI patients completed the study. Of those, 31.11% showed little or no improvement; 24.45% moderate to intermediate improvement; 33.33% significant improvement and 11.11% improved almost to resolution. In regards to MASI, there was a significant improvement, with a reduction from 21.33% to 11.19%.
CONCLUSIONS: The proposed association showed satisfactory results, constituting an innovative, replicable and safe therapeutic modality for the treatment of melasma.

The nasal region is often affected by cutaneous neoplasm, especially in individuals of low phototypes, where the incidence of basal cell carcinoma is high. Surgical defects in the nasal wing and perinasal region constitute a challenge to its reconstruction since it involves several cosmetic units and preservation of the nasal groove. The preservation of the limits between these units is thus fundamental for good functional and aesthetic results. This article aims to show the application of the Shark Island Flap for the correction of defects in the nasal and perinasal regions.
