Introduction: Obesity is a major health problem worldwide due to its high morbidity and mortality. Objective: To evaluate the reduction of abdominal fat in volunteers who underwent low-frequency diode laser therapy. Methods: A total of 60 volunteers (18 to 50 years of age, with a BMI of between 18.5 kg/m2 and 30 kg/m2, and who had abdominal fat), underwent a treatment performed twice a week for 31 days and were then evaluated. The abdominal circumference was evaluated in three locations, with photographic and ultrasound images taken of the studied area. Results: There was a reduction in the abdominal circumference measurements in the evaluated sites, with dermal compression and a significant reduction of hypodermis verified through ultrasound. Conclusion: The low-frequency diode laser therapy showed significant results in the reduction of localized fat and abdominal circumference measurements.

Basal cell carcinoma corresponds to the majority of malignant cutaneous malignancies in Brazil, predominating in middle-aged white individuals, mainly affecting the upper two-thirds of the face and occurring due to several etiological factors. The ideal treatment consists of complete removal with free lesion margins. For better functional and aesthetic results, reconstruction of the surgical wound with flaps or grafts may be necessary. Two types of reconstruction are described in patients with double surgical defects on the face, close to each other: one with a single rotation flap and another with a double rotation flap, also called Yin-Yang.
