Structural alterations resulting from the aging process of the face are related to muscular action, skin sagging, loss of bone support, and decrease in the volume of facial fat compartments-all inducing alterations in facial contour over the years. The authors have carried out a review of the main causes linked to the so-called facial contour alteration in aging and defined a new denomination for this process: "facial squaring", the process through which the shape of the face-which is that of an inverted trapezoid in youth-becomes that of a square over time.

Introdução: Nasal filling can be used as an alternative to traditional rhinoplasty aiming at correcting small nasal defects and for complementation or correction after surgical procedures. Objective: To describe the profile of patients who underwent nasal filling and demonstrate the efficacy and safety of a new hyaluronic acid based filling substance. Methods: Retrospective analysis with statistical study of nasal filling procedures conducted in 280 patients. Results: The sample was composed mostly of Caucasian women with a mean age of 43 years. The nasal regions more commonly treated with the filler were the nasal root, tip and septum. Patients showed significant improvement and expressed satisfaction with the results. 17.1% of the patients were re-treated, and 7.2% had easy to resolve complications. Conclusion: The results were long lasting and natural, especially those related to thinning of the nasal tip.

Lesions in difficult locations within the auricular pavilion have been a major challenge for dermatologic surgeons, since access to their surgical approach tends to be complicated. In this article, the authors describe a case of basal cell carcinoma affecting the lower part of the left auricular concha that was resected by Mohs micrographic surgery, whose approach proved to be challenging. The authors describe a tactic to gain better access and visibility of the surgical field and facilitate the implementation of the procedure.
