“…Ultrasound-assisted liposuction fundamentally differs from traditional suction-assisted liposuction in that it uses the application of ultrasound energy to selectively emulsify subcutaneous adipose tissue through micromechanical, thermal, and microcavitation effects [7]. A previous study in our laboratory investigated whether differences in proliferative capacity and osteogenic potential existed between ASCs obtained by means of suction-assisted liposuction versus thirdgeneration ultrasound-assisted liposuction (VASER Lipo System) [11].…”

“…Until recently, research investigating ASCs has primarily been performed on specimens obtained principally by means of suction-assisted liposuction, as this has been the gold standard since first introduced by Arpad and Giorgio Fischer in the 1970s [6,7]. Ultrasound-assisted liposuction, introduced by Scuderi and Zocchi in 1987, uses ultrasonic energy to allow selective destruction of subcutaneous adipose tissue…”

Harvesting adipose-derived stromal cells (ASCs) for tissue engineering is frequently done through liposuction. However, several different techniques exist. Although third-generation ultrasoundassisted liposuction has been shown to not have a negative effect on ASCs, the impact of laserassisted liposuction on the quality and differentiation potential of ASCs has not been studied. Therefore, ASCs were harvested from laser-assisted lipoaspirate and suction-assisted lipoaspirate. Next, in vitro parameters of cell yield, cell viability and proliferation, surface marker phenotype, osteogenic differentiation, and adipogenic differentiation were performed. Finally, in vivo bone formation was assessed using a critical-sized cranial defect in athymic nude mice. Although ASCs isolated from suction-assisted lipoaspirate and laser-assisted lipoaspirate both successfully underwent osteogenic and adipogenic differentiation, the cell yield, viability, proliferation, and frequency of ASCs (CD34 ؉ CD31 − CD45 − ) in the stromal vascular fraction were all significantly less with laser-assisted liposuction in vitro (p < .05). In vivo, quantification of osseous healing by micro-computed tomography revealed significantly more healing with ASCs isolated from suction-assisted lipoaspirate relative to laser-assisted lipoaspirate at the 4-, 6-, and 8-week time points (p < .05). Therefore, as laser-assisted liposuction appears to negatively impact the biology of ASCs, cell harvest using suction-assisted liposuction is preferable for tissue-engineering purposes.

“…Zocchi first developed ultrasound-assisted lipoaspiration in the 1980s, which implemented the use of ultrasound energy to selectively emulsify low-density adipocytes by means of micromechanical, thermal, and microcavitational effects before suction evacuation. 14,15 In concept, the potential clinical gains to be appreciated by both patients and surgeons through the implementation of this technology are attractive, and evidence derived from recent investigations to support this potential is accumulating. Ultrasoundassisted lipoaspiration has been touted by its proponents for improving on traditional lipoaspiration techniques by affording the patient benefits of being less traumatic to treated tissues through the application of energy selective for adipocytes, and being particularly efficacious in the treatment of dense, fibrous anatomical locations.…”

These findings suggest that exposure of adipose-derived stromal cells to ultrasound energy during tissue harvest by means of third-generation ultrasound-assisted lipoaspiration does not impart a negative consequence toward their proliferative capacity or osteogenic potential. Thus, the cells harvested using third-generation ultrasound-assisted lipoaspiration are comparable to those obtained by means of suction-assisted lipoaspiration for use in the study of osteogenic differentiation and skeletal tissue engineering.

“…UAL usually eliminates the problem of excessive skin by means of skin contraction. Nevertheless, this technique should be performed with special care to avoid the risk of thermal burns (1,8 (8,9). Proponents of these techniques have reported a better excision of fibrous fat with contour control, and postoperative skin contraction.…”

“…However, latest technological advances have not decreased the importance of classical liposuction, which continues to be used for a variety of indications. In addition, similar to the classical liposuction technique, this technique may require direct glandular tissue excision when there exists firm and resistant gynecomastia material (9,10).…”

ÖZET Amaç: Jinekomasti, glandüler, duktal veya adipozal bileşenlerin artması sonucu erkek meme dokusunun iyi huylu büyümesidir. Bu çalışmada, jinekomasti tedavisinde cerrahın intraoperatif değerlendirmesine bağlı olarak konvansiyonel liposuctiondan yapıldıktan sonra glandüler eksizyon gereksinimini araştırmayı amaçladık. Yöntem ve Metotlar: 2013 ve 2017 yılları arasında jinekomasti nedeniyle ameliyat edilen erkek hastaların tibbi kayıtları retrospektif olarak incelendi. Tüm jinekomastili erkek memeleri liposuction yöntemi ile ameliyat edildikten sonra cerrahların intraoperatif değerlendirmesine bağlı olarak ihtiyaç duyulan memelere glandüler eksizyon da uygulandı. Bulgular: 52 erkekte (ortalama 25.61 yıl, ortalama takip: 21.5 ay) toplam 99 meme (5 tek taraflı, 47 bilateral) ameliyat edildi. Toplam 71 (% 71.7) memeye sadece liposuction uygulandı. Geriye kalan 28 (% 28.2) meme, liposuction ve ardından glandüler eksizyon ile ameliyat edildi. Tek başına liposuction uygulanan 8 (% 11.2) memede, takiplerde revizyon ihtiyacı olduğu görüldü ve 6 ay sonra glandüer eksizyon uygulandı. Duktal eksizyon ile ameliyat edilen 8 meme eklendiğinde, 99 memenin 36'sına (% 36.3) liposuction + rezeksiyon uygulanmıştır. Sonuç: Retrospektif olarak yapılan bu çalışmada görülmüştür ki jinekomasti nedeniyle ameliyata alınan memelerin yaklaşık olarak üçte ikisinde liposuction tek başına yeterli bir cerrahi sağlarken üçte birinde liposuction ile beraber glandüler eksizyon gerekmektedir. İntraoperative olarak liposuction sonrası fizik muayene ile bariz glanduler doku kalmış hastalarda glandüler eksizyon uygulamasından kaçınılmamalıdır. Anahtar Kelimeler: jinekomasti; liposuction; glandüler eksizyon ABSTRACT Purpose: Gynecomastia refers to benign enlargement of male mammary tissue as a result of an increase of glandular, ductal, or adiposal components. In this study, we aimed to investigate the need of glandular excision after conventional liposuction in gynecomastia based on the intraoperative evaluation of surgeons. Patients and Methods:We reviewed the medical records of males who were operated for gynecomastia between 2013 and 2017. Although all breasts were operated with the liposuction, a glandular excision was also applied to the breasts that were needed depending on the surgeon's intraoperative evaluation. Results: A total of 99 breasts (5 unilateral, 47 bilateral) were operated in 52 males (mean age 25.61 years, mean follow-up: 21.5 months). A total of 71 (71.7%) breasts were operated with liposuction alone. The remaining 28 (28.2%) breasts were operated with liposuction followed by glandular excision. Only 8 (11.2%) breasts that underwent liposuction alone needed a revision with glandular re-excision 6 months later. When 8 breasts operated with ductal excision were added, 36 (36.3%) of 99 breasts were operated with liposuction+resection. Conclusion: This retrospective study showed that liposuction alone provided satisfactory results in about two thirds of breasts with gynecomastia whereas glandular re-excision becomes necessary in ad...
