In Vivo Endoscopy of Septal Fibers Following Different Liposuction Techniques Reveals Varying Degrees of Traumatization. 
Afschin Fatemi, MD

The removal of fat via liposuction requires disruption of adipose tissue and the intrinsic collagen-based septal fiber network that supports and protects the blood and nerve supply to adipose tissue. Using septal fiber preservation as a marker for the relative trauma of a given liposuction technique, we quantified and compared the number of intact septal fibers following various liposuction methods using in vivo endoscopy.
