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

BACKGROUND: 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. OBJECTIVE: The aim of our study is to prove the efficacy and safety of the DAS Medical® device in dermatochalasis size reduction. METHODS: 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. RESULTS: 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. CONCLUSION: 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. LEVEL OF EVIDENCE IV: This journal requires that authors assign a level of evidence to each article.

Internal pudendal perforator artery flap harvesting without pre-operative imaging: Reliability and approach.

Since its initial description in 1996 by Yii and Niranjan, the internal pudendal perforator flap (also known as the Singapore flap, the gluteal fold flap, and the lotus petal flap) has become a workhorse in perineal soft tissue reconstruction. In 2001, Hashimoto described the presence of three to five perforators in the perineal anogenital triangle. The ischial tuberosity has thus become a useful anatomic landmark for the safe boundary of medial dissection during flap elevation, in order to avoid damaging the perforator vessels. The objective of the present study was to evaluate the perforators' positions within the anogenital triangle by using color Doppler ultrasound. In a study of 15 subjects in the lithotomy position, we identified a total of 24 perforator vessels with a diameter greater than 5 mm. We noted the vessels' positions using orthonormal measurements, according to the distance from the midline and the distance on a straight line between the two ischial tuberosities (i.e. consistent bony anatomic landmarks that are independent of the patient's height and body mass index). The mean distance between the ischial tuberosity and the internal pudendal perforator was 27.3 mm. Based on our present results, we consider that routine ultrasound identification and dissection of the perforators is not always required before pudendal flap harvesting. This decreases the operating time and simplifies the flap harvesting procedure.
