To date, optimal laser parameters have not been determined. Many surgeons use 35-50 watts at an interval of 0.05 seconds. Use of dilators After creating recipient sites, dilators may be used to enlarge the opening by pushing adjacent scalp aside and to provide hemostasis. Most surgeons use Jewler's forceps or similar small, nontoothed forceps to insert grafts. Graft should be gently inserted by grasping the fat immediately beneath it to minimize trauma to the follicle.
Some surgeons use a needle to insert graft and gently tease the graft into place.
More recently, implantation devices have been designed that create recipient site and insert graft. Larger studies of these newer devices, which may prove beneficial, are underway. Although use of prophylactic antibiotics can decrease risk of wound infection, risk of hypersensitivity reaction and emergence of resistant organisms need to be considered. For most patients first-generation cephalosporin is used, unless a history of cephalosporin allergy exists. If cephalosporin hypersensitivity exists, azithromycin or ciprofloxacin may be substituted.
