Abstract

BACKGROUND:

The advent of high-energy carbon dioxide (CO2) laser-assisted hair transplantation in recent years provides a new recipient area technique for hair restoration surgery. It offers the advantages of less bleeding, time consumption, and graft compression. Specific laser parameters have been recommended in Caucasian but not Oriental patients.

OBJECTIVE:

To determine the effectiveness as well as appropriate parameters of laser hair transplantation in Oriental patients.

METHODS:

A Sharplan SilkTouch laser with the Flashscanner set to produce a 0.8-1-mm recipient site hole was employed for all subjects. Various CO2 laser parameters were used to compare the graft survival rate with traditional Nokor needle or microdilator methods for micrografting on each side of the scalp. A total of 20 patients joined the study in the past 18 months. A skin biopsy was performed to examine the tissue effect of the different laser parameters.

RESULTS:

Hair survival was less than that seen with conventional micrografting techniques in the first five cases, in whom CO2 laser parameters of 36-40 W and 0.2-0.7 seconds were used. After adjusting the parameters to 55 W and 0.1-0.15 seconds, the survival rate increased to between 80% and 90%. In addition, most patients thought the laser-prepared sites resulted in a more natural appearance and better hair density, when they were compared with conventionally prepared sites.

CONCLUSIONS:

From our study, we find that CO2 laser parameters of 55 W and 0.1-0.15 seconds seem to be the appropriate parameters for Oriental hair transplant patients. Further studies are required to establish laser parameters that will produce better hair survival.
