To date, optimal laser parameters have not been determined. Many surgeons use 35-50 W at an interval of 0.05 seconds. Dilator use After creating recipient sites, dilators may be used to enlarge the opening, by pushing adjacent scalp aside, and to provide hemostasis. Most surgeons use jeweler's forceps or similar small nontoothed forceps to insert grafts. Gently insert a graft by grasping the fat immediately beneath it to minimize trauma to the follicle.
Some surgeons use a needle to insert and tease grafts gently into place.
More recently, implantation devices have been designed that create recipient site and insert grafts. Larger studies of these newer devices, which may prove beneficial, are underway. 10 Medications Antibiotic use Significant controversy remains regarding the use of prophylactic antibiotics in hair transplant surgery, since few studies support the use of antibiotics. Although prophylactic antibiotics can decrease the risk of wound infection, the risk of hypersensitivity reactions and the emergence of resistant organisms need to be considered. For most patients, first-generation cephalosporin is used, unless a history of cephalosporin allergy exists.
