Non-surgical techniques used in the rejuvenation of the periorbital region, notably regarding injections of hyaluronic acid for the correction of depressed areas. However, in spite of the good results brought by these described techniques and products, there are still complications linked to their use, such as color alterations, irregularities in the surface of the skin, local edema, and long time of recovery. In an attempt to abate those undesirable effects, thirty patients were treated with a filler of low hyaluronic acid concentration, slowly and sequentially depositing small drops in a superficial plane, reminding a string of beads, with the subsequent application of digital pressure. This technique of easy application, has presented good aesthetical results and lower risk of undesirable effects and complications.

Diverse techniques for rejuvenating the skin of the inferior periorbital region – ranging from chemical peels to more modern technologies, such as lasers – have been described in the literature. Although countless advances have been made, the results are not always satisfactory.We describe a new technique for rejuvenating this area: punctual electrocoagulation of the superficial layers of the skin.

This paper describes a lip filling technique that administers hyaluronic acid using microcannulas. This technique considerably reduces the number of punctures compared to the conventional method, which uses needles. In addition, the microcannula’s blunt tip reduces the risks of intravascular injection of the substance and of disrupting key structures such as vessels and nerves. The results obtained by the authors confirm the less frequent occurrence of adverse effects and a high degree of physician and patient satisfaction.

The protrusion of the orbital fat, aggravated by local dyschromia, causes an unpleasant aesthetic appearance, which worsens with age. This study describes 15 cases of treating the tear trough with hyaluronic acid filling. The substance was deeply injected through retro injection. Eleven patients (73%) were satisfied with the procedure. Two cases (13%) presented edema in the treated area, one case (6%) developed hyperchromia of the lower eyelids, and another (6%) developed an irregularity on the cutaneous surface in the area that was filled, and was treated with hyaluronidase. This technique demonstrated good results, with no serious complications.

Introduction: Due to the risk of invasion of the orbital cavity and involvement of noble structures, the periocular region requires specific knowledge related to the anatomy and biological behavior of tumors in this region. Objective: To present the particularities and complexity of the approach to periocular tumors, through the analysis of cases treated at a Mohs micrographic surgery specialist center. Methods: A retrospective, observational, cross-sectional study was carried out based on data collected through a review of medical records, operative records, and photographic archives. Thirty-four cases were analyzed between April 2010 and April 2014. Results: Thirty-one basal cell carcinomas, two squamous cell carcinomas, and one sebaceous carcinoma were operated. Of these, 22 (64.70%) were primary tumors, and 12 (35.29%) were recurrent or incompletely excised. The nodular was the most common type of basal cell carcinoma (38.70%), followed by the micronodular (25.80%), the infiltrating (22.58%), the sclerodermiform (6.45%), the superficial (3.22%) and the adenoid (3.22%). Most of the lesions affected the lower eyelid (44.11%), followed in number by the internal canthus (41.17%), the upper eyelid (11.76%), and the external canthus (2,94%). There was only one recurrence following Mohs micrographic surgery. Conclusions: Most tumors had an aggressive histological subtype, especially those located in the internal canthus. Despite the study's limitations, the strict histological control of Mohs micrographic surgery, combined with the multidisciplinary approach to patients, provided excellent oncological, functional, and cosmetic results.

Cutaneous defects of the lower eyelid frequently require reconstructions with grafts or flaps to avoid ectropion. Removal of a basal cell carcinoma from the lower eyelid of a 39-year-old patient resulted in an exclusively cutaneous defect, with transversal and vertical diameters of 32 and 13mm, respectively. Despite the large size of the defect, the elevation of the suborbicularis oculi fascia to the periosteum of the lateral orbital border made primary closure possible. The position of the lower was also reinforced with a lateral canthopexy, with excellent aesthetic and functional results.
