Hair transplant of follicular units: a 15-case experience

Authorship SCIMAGO INSTITUTIONS RANKINGS

ABSTRACT

Introduction:

The transplant of follicular units (FUs) for hair restoration yields the most natural results. The implantation of 20-25 FU/cm2 has a low risk of follicular damage and yields satisfactory results within two sessions. A density greater than 30-35 FU/cm2 yields the same results within a single session but increases the risk of follicular damage and hair growth loss. We report our experience with 15 cases of hair transplantation, with an implantation density of ≥ 30 FU/cm2 and with incisions made previously using a surgical instrument modified to facilitate implantation.

Method:

A retrospective study of 15 patients who consecutively underwent 17 surgeries between July 2008 and June 2012 and were followed up for 1 year.

Results:

A mean of 1433.3 FUs and 3019.8 hairs were implanted per surgery. The mean surgical duration was 10 hours and 23 minutes. Satisfactory hair growth occurred, and results were visible at 6 months onward with few complications. Of the 15 patients, two required a second session.

Conclusions:

The technique used here enabled delicate manipulation of the FUs and high-density implantation that achieved good results within one session but required an above-average execution time and should be restricted to small areas requiring greater density.
