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.

Introduction: The evolution of filling techniques allowed a three-dimensional approach to the face: nowadays volumetric restoration is more important than grooves.
Objective: Description of an unpublished technique of facial volumization through the injection of filler in the supra-auricular region, with a detailed review of the regional anatomy.
Methods: A retrospective case-control study was conducted in patients presenting skin mobility in the temporo-parietal region. The injection of Hyaluronic Acid for volumetric replacement was done using cannulae, bolus and fan techniques in the supra-auricular region, limited antero-superiorly by the area of ¿¿hair implantation and inferiorly by the tragus. The patients were evaluated clinically, photographed and had their data analyzed by statistics.
Results: 152 women and 13 men aged 24 to 84 years were treated between July and September 2016. The volume of Hyaluronic Acid used in the patients ranged from 0.6 to 2.6 ml. In 8 cases local edema was observed due to hematoma during application, that was controlled by digital compression. Significant improvement of the facial contour was observed.
Conclusion: The use of fillers in the supra-auricular region allows a three-dimensional approach and promotes static and dynamic rejuvenation of the entire face.
