The reconstruction of defects resulting from the removal of facial tumors is always a challenge, given that the functional integrity of the treated area and the risk of retractions and unattractive scars must be carefully assessed. Grafts, often the best option in reconstruction, require that the donor and recipient areas present tissular similarities. The present study proposes the superior eyelid tissue as a good option in 12 patients with facial basal cell carcinomas and excess tissue in the superior eyelids.

Introduction: A trend is currently observed towards the indication of less invasive procedures, isolated or combined, in the treatment of stretch marks, scars, and the effects of aging. Microneedling is an option that stimulates collagen production without causing the total de-epithelization observed in ablative techniques. Objective: To carry out an experimental study aimed at establishing the correlation between the lengths of the cylinder's needles used for microneedling with the depth of the damage inflicted to the skin. Methods: Biopsies were performed in skin areas of alive pigs that underwent microneedling with cylinders containing 192 needles of 0. 5 - 1, 1. 5 -2 and 2. 5 mm. Results: Microscopic examination carried out immediately after the procedure revealed vascular ectasia with extravasation of red blood cells, affecting the papillary dermis with 0. 5 mm needles and reaching the reticular dermis with longer needles. The authors propose classifying the inflicted injury as mild (0. 5 mm needles), moderate (1. 0 and 1. 5 mm needles), and deep (2. 0 to 2. 5mm needles). Conclusion: The microneedling procedure can be indicated for a broad spectrum of skin alterations when the goal is to stimulate the production of collagen. Establishing the relationship between the length of the needle used and the resulting damage to the skin assists in choosing the microneedling tool used in different directions.

Introduction: Atrophic stretch marks constitute skin disorders characterized by the loss of collagen and elastin in the dermis, and resemble scars. Fractional lasers, microneedling and chemical peels have led to good outcomes in some cases, however there is no ideal treatment.
Objective: The objective of the present retrospective clinical study was to evaluate the effectiveness of Pulsed Radiofrequency with Multineedles (RFPM^®) in late atrophic stretch marks.
Methods: A retrospective study of the safety and effectiveness of the technique was carried out by evaluating outcomes with the application of a patient satisfaction questionnaire and the assessment of clinical results by independent dermatologist physicians.
Results: A total of 8 patients (aged between 22 and 38 years) who underwent the technique were evaluated, of whom 100% reported satisfaction with the outcomes. Additionally, in the comparative evaluation of photographs carried out by two independent dermatologist physicians, the improvement rate was 50% in 2 patients and 75% in 8 patients . Post-inflammatory hyperpigmentation was observed in 10 to 20 days after the treatment in 6 patients, having been reversed after clinical treatment.
Conclusions: The new procedure is an option in the treatment of atrophic stretch marks.

Introduction: Numerous techniques have been described to treat the earlobe aging. Surgical and nonsurgical methods as peelings, CO₂ laser and fillings have been proposed to produce collagen remodeling.
Objective: The objective of this retrospective clinical study was to evaluate the effectiveness of microneedling assisted radiofrequency for earlobe aging.
Methods: Retrospective study of the technique's safety and effectiveness through the evaluation of the results with the application of a satisfaction questionnaire to patients and of the analysis of clinical outcomes by independent dermatologists.
Results: Twelvy patients aged between 48 and 67 years who underwent the technique were evaluated. One hundred percent of the patients reported satisfaction with the results, whereas in the comparative evaluation of the photographs carried out by two independent dermatologists the rate of improvement was 75% in four patients, 100% in eigth patients. Post-inflammatory hyperpigmentation was observed ten to 15 days after the treatment in five patients, though it was reversed after clinical treatment.
Conclusion: This new procedure emerges as an alternative treatment for earlobe aging.

Introduction: The use of microneedling techniques has become increasingly important in the correction of scars.
Objective: To evaluate the results of percutaneous induction of collagen with needles in scars developed after automobile accidents.
Methods: A retrospective, descriptive and monocentric study analyzed medical records containing standardized photographs taken at baseline and 3 months after a single microneedling session, in 9 patients diagnosed with post-traumatic scars who were treated using the same protocol. Clinical and photographic evaluations of the treatment were performed by the investigator 3 months after the procedure according to a category scale (very good, good, reasonable, poor). Patient satisfaction questionnaires were also applied at this experimental timepoint.
Results: The clinical and photographic evaluation classified 5 patients as very good and 4 as good regarding the results achieved. All patients reported satisfaction with the outcomes.
Conclusions: The use of needle-induced percutaneous collagen yielded good esthetical and functional results in scars developed following accidental trauma. Adverse effects were not observed, which suggests that the described procedure has a good safety profile.

Introduction: Depressed acne scars always arise as a therapeutic challenge. Fractional lasers, surgical approaches and chemical peels have attempted to offer acceptable aesthetic results, however it is still difficult to determine the ideal treatment. Objective: To evaluate the efficacy of Percutaneous Collagen Induction with needles (IPCA^®) associated with Pulsed Radiofrequency with Multineedles (RFPM^®) in depressed acne scars. Methods: Retrospective study of the safety and effectiveness of the technique through the evaluation of results based on a satisfaction questionnaire answered by the patients and the clinical and photographic assessment carried out by a dermatologist. Results: Thirteen patients (aged between 21 and 37 years) who had undergone the combination treatment were evaluated. All (100%) reported satisfaction with the outcomes, while in the comparative evaluation of photographs yielded an improvement rate of 50% in 2 patients and of 70% in 6 patients. Conclusion: This new therapeutic proposal arises as an alternative in the treatment of depressed acne scars.
