High Definition Liposuction Using Third Generation Ultrasound Versus Conventional Liposuction of the Lower Back and Upper Thigh Region: A Comparative Study

Abstract

Introduction: The accuracy of results of liposuction hadlong been related to the aspiration cannulas as much as it isrelated to surgeon experience. The cannulas tips, length,diameter, design, number of holes shapes and negative pressurehad drawn the attention of all surgeons in order to modifytheir outcomes. The addition of technologies that provideenergy based devices has enriched the procedure and improvedpatient satisfaction. Ultrasound assisted liposuction had severalcomplications included severe burns and other problems, lessenergy is used in third generation ultrasound assisted liposuctionthan second generation liposound which make it saferwith better results. A much more accurate technique wasdescribed by Hoyos to improve body contouring by usingVASER assisted liposuction.Aim of the Study: To investigate the superiority of highdefinition liposuction using third generation liposound inlower back and upper thigh region as regarding patient satisfactionand their need for secondary procedures.Patients and Methods: 20 patients with age ranged from18-40 years old and BMI=25-30 having lipodystrophy of thelower back and upper thigh and trochanteric areas with moderateskin tone, only non-smoker-non diabetic-non hypertensivewere included in the study. Patients were divided into twogroups; Group A included 10 patients who undergone suctionassisted liposculpture and Group B: Included 10 patients whohad high definition liposuction using third generation internalultrasound machine. Both subjective and objective evaluationwas done. Objective evaluation was done by measurement ofboth pre operative drawn line starting from mid sacral pointto highest point of iliac crest and post-operative measurementat one and six month in both groups.Results: This study involved 20 women divided into twogroups. Group B patients had less blood content of the aspirate,longer time of the procedure (add ultrasound timing) morepost-operative edema, more obvious skin retraction alongpost-operative period. While Group A patients showed overallless edema and more ecchymosis with less satisfaction andmore irregularities and need for secondary procedures.Conclusion: High definition liposcution using third generationinternal ultrasound showed higher skin contraction,better body shape and contour.
