Update on laser-assisted hair transplantation.
OBJECTIVE
The aim of this study was to examine the laser parameters evaluated in previous studies with a larger patient group (n = 491), particularly with regard to patient-related and operation-related advantages and disadvantages. Particular attention was devoted to hair growth rate and the postoperative healing process.


METHODS
The implant holes were created using an optomechanical, beam-focusing miniature scanner and a 80-W carbon dioxide laser.


RESULTS
All patients in Norwood classification groups I, II, and III displayed proper hair growth. On an average of all patients treated, this occurred with a delay of some 4-6 weeks. Compared with the cold steel technique, the healing process was shortened by 3-4 days.


CONCLUSIONS
Making allowances for the formula: minimum wattage with a minimum exposure time and a minimum hole diameter, the laser is an ideal instrument to use on the hairline and crown.
