The skin flaps are surgical techniques particularly useful to aesthetic repair in cases of extended excision and/or unusual sites, as in the ear. Many skin flaps options were already reported, resulting in variable results of the theoretical knowledge and practical experience of the surgeon. This article aims to describe two successful cases of ear reconstruction with the use of anterior and posterior flaps and to review the current literature.

Acne scars present at the end of the inflammatory phase of acne vulgaris have been treated with procedures that stimulate the production of collagen, such as microneedling. Six patients with acne scars were selected. Microneedling was performed with 2.5 mm needles. Subjective improvement was observed in all patients. In the technique of percutaneous collagen induction there is release of cytokines, growth factors and angiogenesis, with final production of type I collagen, making microneedling an excellent option for the treatment of acne scars, both for its cost/ benefit and for not drawing patients away from their daily activities.
