The Outcomes Assessment of the Plasma Blade Technology in Upper Blepharoplasties: A Prospective Study on a Series of 25 Patients

The Dermo Ablation Surgery (DAS) Medical® (Technolux, Italy) device is a plasma blade which induces a plasma voltaic arc causing a retraction in the epidermis and superficial dermis.
The aim of our study is to prove the efficacy and safety of the DAS Medical® device in dermatochalasis size reduction.
Our prospective study included 25 adult patients presenting with upper eyelid dermatochalasis undergoing a two-session treatment protocol with the DAS Medical® device (with a month treatment-free interval). The primary end point was the reduction in the size of the dermatochalasis. The secondary end points were patient satisfaction, and a blinded assessment of the outcomes was carried out by 15 plastic surgery specialists on post-procedural pictures.
The mean reduction in the size of the dermatochalasis was estimated at 2.47 mm on a 6-month follow-up (13.5 mm at T0 vs. 11.03 mm at 6 months, p = 0.0002) and 1.97 mm on a 12-month follow-up ((13.5 mm at T0 vs. 11.53 mm at 12 months, p = 0.0055). Eighty per cent of the patients and 78% of the assessing clinicians were globally satisfied with the results on a 12-month follow-up. The mean visual analogue pain score reported during the treatment was 4.5/10; MEOPA® was used in 23% of cases. No irreversible post-procedural sequelae (complications) were observed.
Voltaic plasma arc treatment with DAS Medical® is an effective technique for non-invasive blepharoplasty on moderate dermatochalasis patients not suffering from palpebral lipoptosis and is very well tolerated. It can be usefully and successfully associated with surgery.
