Abstract
Background: Surgical complications in hair transplantation can sometimes be a serious matter. Most of the published literature on this issue deals with individual case reports rather than larger series of patients. Objective: The authors analyze complications in 425 consecutive patients undergoing 533 hair transplantations. Methods: Patients with androgenetic alopecia (407 men and 17 women), cicatricial alopecia (9 men and 8 women), and malformations (1 man and 3 women) with a mean age of 36.9 years (standard deviation, 10.4 yrs) underwent hair transplantation between 1995 and 2006 and were followed up postoperatively for at least 1 year. Data on surgical complications were retrospectively analyzed. Results: The overall complication rate in our series was 4.7%, including enlarged scar (1.2%), folliculitis (1.0%), necrosis in the donor area (0.8%), keloids (0.4%), bleeding (0.2%), hiccups (0.2%), infection (0.2%), and pyogenic granuloma (0.2%). The frequency of enlarged scar increased proportionally according to the number of surgical procedures. Conclusions: The hair transplantation complication rate in this series was 4.7%. Good communication between patient and surgeon, a complete clinical and laboratory assessment of the patient, accurate surgical technique, specific equipment, a trained surgical team, and careful postoperative attention to the patient are crucial for successful hair transplantation and for decreasing complication rates.
