Eyebrow reconstruction.

This is a systematic review of eyebrow reconstruction options, using the PubMed database, as well as dermatology and plastic surgery texts. Eyebrow reconstruction options in various clinical scenarios (small, large, medial, lateral, and total defects) are presented. The goals of eyebrow reconstruction are to provide structural, functional, and aesthetic restoration. A good understanding of various eyebrow reconstruction techniques is essential for plastic, dermatologic, and oculoplastic surgeons.

Hydrogen peroxide and wound healing: a theoretical and practical review for hair transplant surgeons.

BACKGROUND: In most hair restoration practices, hydrogen peroxide has been routinely used to remove blood during and after hair transplant surgery. In other specialties, hydrogen peroxide is also used in these ways: wound cleaning, prevention of infection, hemostasis, and removal of debris. Despite its widespread use, there are still concerns and controversy about the potential toxic effect of hydrogen peroxide. OBJECTIVE: The objective was to review all available literature including in vivo and in vitro effects of hydrogen peroxide, as well as general wound healing research. MATERIAL AND METHODS: Literature up to and including the past three decades was investigated. RESULTS: Two pilot studies were found, and there are not enough data examining the real impact of using hydrogen peroxide in hair transplant surgery. In other specialties, H(2)O(2) appears to have positive effects, such as stimulation of vascular endothelial growth factor, induction of fibroblast proliferation, and collagen, or negative effects, such as cytotoxicity, inhibition of keratinocyte migration, disruption of scarless fetal wound repair, and apoptosis. CONCLUSIONS: There are not enough data in hair restoration surgery about the use of hydrogen peroxide, and it is unknown and unclear what the optimum dilution should be. Positive and negative effects were found in other specialties. Further studies are recommended. The authors have indicated no significant interest with commercial supporters.
