Paradigm Shift from Linear Strip to Follicular Unit Excision in Hair Restoration Surgery

Abstract

AbstractFollicular unit excision (FUE) is a very effective and valuable modality for obtaining donor hair follicles using manual, motorized, or robotic devices to harvest individual donor follicular units in situ without a linear donor scar or visible scarring making it ideal for patients who wish to wear their hair short and hide signs of surgery. Over the past two decades, FUE has become increasingly popular, and the rising demand for FUE has driven the worldwide market size of hair restoration surgery (HRS) to an unprecedented height.FUE has revolutionized the HRS industry and offers excellent cosmesis and high patient satisfaction. Unfortunately, a large part of the favorable appeal of FUE is due to false claims that it is “minimally invasive,” “scarless,” or “not even surgery.” Most patients opt-in for FUE due to these misconceptions, which are advertised by “black-market” clinics offering low-cost FUE surgery performed by amateur, nonprofessional technicians on unsuspected patients. The technique appears deceptively simple, and many neophyte surgeons falsely believe that the learning curve of FUE is short because the barrier of entry is low and no previous surgical skill is required. Nevertheless, injuries on grafts are extremely easy to occur since FUE is a blind technique and can be minimized only with excellent technique, which takes years to master.FUE actually presents unique challenges for the surgeon and carries potential long-term permanent side effects if not performed properly. The surgeon must have a thorough understanding of the nuances of the FUE surgical technique to ensure consistent graft quality and favorable cosmesis of both donor and recipient areas. Efficient FUE requires dexterity, training, dedication, devotion, enthusiasm, cognitive clarity, scientific knowledge, experience, and an extended learning curve.FUE is an invaluable addition to the armamentarium of a hair restoration surgeon but has to be judiciously performed.
