Introduction: The accuracy of results of liposuction had
long been related to the aspiration cannulas as much as it is
related to surgeon experience. The cannulas tips, length,
diameter, design, number of holes shapes and negative pressure
had drawn the attention of all surgeons in order to modify
their outcomes. The addition of technologies that provide
energy based devices has enriched the procedure and improved
patient satisfaction. Ultrasound assisted liposuction had several
complications included severe burns and other problems, less
energy is used in third generation ultrasound assisted liposuction
than second generation liposound which make it safer
with better results. A much more accurate technique was
described by Hoyos to improve body contouring by using
VASER assisted liposuction.
Aim of the Study: To investigate the superiority of high
definition liposuction using third generation liposound in
lower back and upper thigh region as regarding patient satisfaction
and their need for secondary procedures.
Patients and Methods: 20 patients with age ranged from
18-40 years old and BMI=25-30 having lipodystrophy of the
lower back and upper thigh and trochanteric areas with moderate
skin tone, only non-smoker-non diabetic-non hypertensive
were included in the study. Patients were divided into two
groups; Group A included 10 patients who undergone suction
assisted liposculpture and Group B: Included 10 patients who
had high definition liposuction using third generation internal
ultrasound machine. Both subjective and objective evaluation
was done. Objective evaluation was done by measurement of
both pre operative drawn line starting from mid sacral point
to highest point of iliac crest and post-operative measurement
at one and six month in both groups.
Results: This study involved 20 women divided into two
groups. Group B patients had less blood content of the aspirate,
longer time of the procedure (add ultrasound timing) more
post-operative edema, more obvious skin retraction along
post-operative period. While Group A patients showed overall
less edema and more ecchymosis with less satisfaction and
more irregularities and need for secondary procedures.
Conclusion: High definition liposcution using third generation
internal ultrasound showed higher skin contraction,
better body shape and contour.
