This study aimed to describe the technique used by the authors in treating tear-trough deformity and to illustrate the effectiveness of high-frequency diagnostic ultrasound in the assessment of dermal filler longevity. In this consecutive interventional nonrandomized case series, 22 patients (18 women and 4 men) were evaluated. They ranged in age from 29 to 65 years (mean, 46.59 years ± 10.0 years). The patients were given multiple hyaluronic acid injections in the tear-trough area between 2009 and 2011. The injected areas then were evaluated with sonographic scans during the follow-up period. All the patients were examined preoperatively, 7 days after injection, then after 1, 6, and 12 months, and finally once a year. Pre- and postoperative photographs using standard positioning and lighting were taken as well as high-frequency ultrasound scans using a 15-MHz scanner with an axial resolution of 15 mm. The injection technique consisted of three to five injections perpendicular to the skin. These were administered just under the orbital rim, creating three column-shaped hyaluronic acid deposits deep in the orbicularis oculi muscle, from 0.2 mm to 0.5 mm below the orbital rim. Approximately 0.1 ml-0.3 ml was injected at a time. This technique creates a deep scaffolding that can fill the orbital hollow. The amount of filler used in each area ranged from 0.1 ml to 0.3 ml (mean, 0.267 ml ± 0.128 ml), whereas the mean filler quantity in each eyelid was 0.45 ml ± 0.14 ml. During the follow-up visit 1 week after the treatment, 21 patients (90 %) required a second series of injections either in the exact same areas or right next to the injected area to obtain a smoother appearance of the skin surface.

Abstract

This study aimed to describe the technique used by the authors in treating tear-trough deformity and to illustrate the effectiveness of high-frequency diagnostic ultrasound in the assessment of dermal filler longevity. In this consecutive interventional nonrandomized case series, 22 patients (18 women and 4 men) were evaluated. They ranged in age from 29 to 65 years (mean, 46.59 years ± 10.0 years). The patients were given multiple hyaluronic acid injections in the tear-trough area between 2009 and 2011. The injected areas then were evaluated with sonographic scans during the follow-up period. All the patients were examined preoperatively, 7 days after injection, then after 1, 6, and 12 months, and finally once a year. Pre- and postoperative photographs using standard positioning and lighting were taken as well as high-frequency ultrasound scans using a 15-MHz scanner with an axial resolution of 15 mm. The injection technique consisted of three to five injections perpendicular to the skin. These were administered just under the orbital rim, creating three column-shaped hyaluronic acid deposits deep in the orbicularis oculi muscle, from 0.2 mm to 0.5 mm below the orbital rim. Approximately 0.1 ml-0.3 ml was injected at a time. This technique creates a deep scaffolding that can fill the orbital hollow. The amount of filler used in each area ranged from 0.1 ml to 0.3 ml (mean, 0.267 ml ± 0.128 ml), whereas the mean filler quantity in each eyelid was 0.45 ml ± 0.14 ml. During the follow-up visit 1 week after the treatment, 21 patients (90 %) required a second series of injections either in the exact same areas or right next to the injected area to obtain a smoother appearance of the skin surface. During the sonographer examination, it was always possible to identify and measure the filler at the site of the injection.
