RESUMEN

Hair loss is a common problem among men and women. Hair replacement surgery (HRS) has become increasingly popular as technological advancements have been made producing remarkably natural results when performed by a skilled surgeon. Although complications from HRS are low compared with other esthetic surgeries, they can still occur even with the best-trained and qualified surgeon or staff. The process of hair restoration can be a long road for some patients and active patient participation and education is key for successful results. In this article, we seek to discuss the surgical risks of HRS and discuss methods to prevent them in your practice.

RESUMEN

Modern hair restoration surgery is based on a technique known as follicular unit transplantation, in which follicular units are the exclusive structures used as hair grafts. In Part 1 of this 2-part review, we describe how the techniques employed in hair transplantation have evolved into their present forms. Anatomic concepts of specific relevance for dermatologists are discussed, including the distribution and ex vivo morphology of scalp follicular units. Male androgenetic alopecia and female pattern hair loss are the most common reasons for hair loss consultations with dermatologists and will be the primary focus of this review. However, because not all hair disorders are suitable for transplantation, this review will also describe which scalp conditions are amenable to surgery and which are not. Guidelines are provided to help dermatologists better define good and bad candidates for hair transplantation. Other conditions for which hair transplantation surgery is indicated are reviewed.

RESUMEN

Objective To observe the effect of eyebrow plasty combined with hair grafting technique.Methods From January 2011 to April 2015,19 patients with eyebrow defect by eyebrow tattooing,operation or trauma received eyebrow plasty.The removed eyebrow tissue was separated into hair follicle units,and the eyebrow shape was redesigned.The hair grafting method was used for repairing eyebrow defect.Scalp was used as a supplement to get enough hair follicle units.Results All but one patients with eyebrow defect obtained good results,and the grafted hairs were growing well with satisfied direction and shape.One patient sustained folliculitis and was cured after inunctions with 75 ％ alcohol.Conclusions Eyebrow plasty combined with hair grafting technique is a safe and effective method for repairing eyebrow defect,with reducing the number of operations and shortening the treatment time.

RESUMEN

Hair restoration is a safe procedure and most of its associated complications are preventable by the surgeon and/or the patient. Recipient area necrosis is rare but arises when an increased number of recipient grafts are utilized and de-vascularization of the scalp occurs. The aim of this study was to investigate and compare all cases and pictures reported in main search engines and Iranian centers of hair transplant to find the dangerous zone of necrosis and to provide a new method for prevention of necrosis. Pictorial analysis of this study revealed that the majority of necrosis (14 of 18) occurs in central region of the scalp and is inclined, particularly, to the right parietal aspect of the scalp. Accordingly, a case series was done and a new method for prevention of scalp necrosis even in dense packing transplantation was discussed.

RESUMEN

Clinicians have long reported that hair-bearing areas tend to heal more rapidly than those lacking hair follicles. In the past decade, numerous scientific studies have corroborated clinical evidence, showing a direct nexus between the human hair follicle and the wound healing process. The migration of epithelial follicular stem cells to the skin surface to help in the wound re-epithelialization and the effect of the hair cycle on the wound healing rate underline the influence of the hair follicle in the healing process. In clinical practice, non-healing wounds are pathologies of high prevalence with significant associated burden costs for the healthcare system. As the population ages, the prevalence of this pathology is expected to increase in future years. The recent advances in understanding the biology of hair follicle stem cells have created the challenges of using this newly acquired knowledge in practical therapeutic applications. Chronic leg ulcers are an example of the targeted pathologies that urgently need better therapies. In this essay, our aim is to raise interest in this question, reviewing what is known in relation to the connections between hair follicles and wound healing, and elaborating on future directions that the field might take, including implications for clinical practice.

RESUMEN

The purpose of this article is to introduce the reader to the topic of follicular unit extraction (FUE) and to present an overview of the value of FUE to patients and physicians. In addition to this, the various methods and instrumentation for performing this method of graft harvest are discussed as well as some of the technique's inherent advantages and disadvantages. Topics unique to FUE, including body hair grafting, plug/minigrafts repair, and donor area management are addressed as well.

RESUMEN

Objective To investigate the therapeutic effect of dense-packing auto hair grafting technique on the restoration of seborrheic alopecia. Methods With local anesthesia, a scalp strip was harvested from the back of the head. Under operating microscope (Various graft was created from the scalp strip, including micro-grafts with 1-2 hairs, mini-grafts with 3-4 hairs and sliver graft with 5-6 hairs. In the alopecia recipient area, micro slots were made with a small triangle-edged needle for the micro-grafts,mini slits were made with mini blade for the mini-grafts and foramen ovale were made with a slot punch. The grafts were then implanted into these holes. Results 32 cases of seborrheice alopecia were treated with the above mentioned technique from March 2007 to July 2009. Postoperative following up for 12-24 month showed that the grafted hairs were growing well with average 90 % survival of the hair. 81 % of the patients obtained satisfactory results with only one stage operation. Six patients needed the second operation to improve the appearance. All of the patients were satisfied with the appearance. Conclusions The dense-packing hair grafting technique with various grafts not only saves time of operation, but also obtains dense grafted hair and well appearance. The results are satisfactory to most patients with only one stage operation.
