Selected AbstractsRecipient-Site Influence in Hair Transplantation: A Confirmative StudyDERMATOLOGIC SURGERY, Issue 6 2009SUNGJOO TOMMY HWANG MD First page of article [source] Use of Nonablative Laser for Corrective Hair TransplantationDERMATOLOGIC SURGERY, Issue 4 2009MARC R. AVRAM MD No abstract is available for this article. [source] Follicular Unit Extraction: Minimally Invasive Surgery for Hair TransplantationDERMATOLOGIC SURGERY, Issue 8 2002William R. Rassman MD background. Follicular Unit Transplantation (FUT) is performed using large numbers of naturally occuring individual follicular units obtained by single-strip harvesting and stereo-microscopic dissection. Donor wound scarring from strip excision, although an infrequent complication, still concerns enough patients that an alternative solution is warranted. objective. The purpose of this paper is to introduce Follicular Unit Extraction (The FOX Procedure), in which individual follicular units are removed directly from the donor region through very small punch excisions, and to describe a test (The FOX Test) that determines which patients are candidates for this procedure. This paper explores the nuances, limitations, and practical aspects of Follicular Unit Extraction (FUE). methods. FUE was performed using 1-mm punches to separate follicular units from the surrounding tissue down to the level of the mid dermis. This was followed by extraction of the follicular units with forceps. The FOX test was developed to determine which patients would be good candidates for the procedure. The test was performed on 200 patients. Representative patients who were FOX-positive and FOX-negative were studied histologically. results. The FOX Test can determine which patients are suitable candidates for FUE. Approximately 25% of the patients biopsied were ideal candidates for FUE and 35% of the patients biopsied were good candidates for extraction. conclusion. FUE is a minimally invasive approach to hair transplantation that obviates the need for a linear donor incision. This technique can serve as an important alternative to traditional hair transplantation in certain patients.

[source] Laser-Assisted Hair Transplantation: Histologic Comparison Between CO2 and Ho:YAG LasersDERMATOLOGIC SURGERY, Issue 4 2001Eugene A. Chu MD Background. Various laser wavelengths and devices have been advocated for use in the creation of recipient channels during hair transplant surgery, including flash-scanned CO2, Ho:YAG (, = 2.12 ,m), and Er:YAG (, = 2.94 ,m). Objective. To determine the tissue injury caused by flash-scanned CO2 and pulsed Ho:YAG lasers during the creation of hair transplant recipient channels and to assess the efficacy of the Ho:YAG laser. Methods. Recipient channels were created in vivo in human scalp tissue using both lasers, and were excised and prepared for histologic examination. Optical micrometry of tissue sections was used to assess thermal injury. Results. The Ho:YAG laser created jagged, irregular-shaped channels with larger zones of thermal injury (superficial deepithelialization, thermal necrosis, and thermal damage). In contrast, the CO2 laser produced well-defined cylindrically shaped channels free of cellular debris with minimal epithelial disruption and significantly less lateral thermal injury. Conclusion. Given that the Ho:YAG produced larger regions of thermal injury and recipient channels that were unacceptable for graft, the CO2 laser remains the better choice for the creation of recipient channels during hair transplant surgery. However, ongoing research will be necessary to determine the optimal laser wavelength and/or devices for this procedure. [source] Naturally Occurring Female Hairline PatternsDERMATOLOGIC SURGERY, Issue 6 2009BERNARD P. NUSBAUM MD BACKGROUND Hair transplantation is gaining popularity in women. Although much has been written about hairline design in male patients, more information is needed about natural female hairlines. OBJECTIVE To determine the frequency, dimensions, and location of structures that compose the female hairline. METHODS Hairline characteristics were measured in 360 female volunteers at an informal hair salon setting. RESULTS A widow's peak was present in 81%. The mean distance from the mid-eyebrow to the frontal midpoint was 5.5 cm. Lateral mounds were observed in 98%. The mean distance from the frontal midpoint to the apex of the lateral mounds was 3.74 cm on the right and 3.97 cm on the left. The mean distance from the apex of the lateral mounds to the apex of the temporal points was 3.78 cm on the right and 3.51 cm on the left. The shape of the temporal recessions was concave triangular or concave oval in 87% of the subjects. CONCLUSION This study provides proposed guidelines for designing the hairline in women. [source] The Potential Role of Minoxidil in the Hair Transplantation SettingDERMATOLOGIC SURGERY, Issue 10 2002Marc R. Avram background. Over the last decade surgical management of hair loss has become an increasingly popular and satisfying procedure for both men and women, as innovations in donor harvesting, graft size, and hairline design have resulted in consistently natural-appearing hair restoration. objective. In addition, a better understanding of the regulation of the hair-growth cycle has led to advances in the pharmacologic treatment of androgenetic alopecia. methods. Currently there are two U.S. Food and Drug Administration (FDA)-approved agents that promote hair regrowth: over-the-counter topical minoxidil solution for men and women and prescription oral finasteride tablets for men. In October 2001, a group of 11 international experts on hair loss and hair transplantation convened to review the physiology and effects of pharmacologic treatments of hair loss and to discuss the value of administering topical minoxidil therapy as an adjunct to hair transplantation. results. This article presents the key findings and consensus points among the participants, including their current use of pharmacologic treatments, strategies for optimal results both pre- and postsurgery, and the importance of realistic patient expectations and compliance. conclusions. Based on the surgeons' clinical experience, the use of approved hair regrowth agents in hair transplant patients with viable but suboptimally functioning follicles in the region to be transplanted can increase hair density, speed regrowth in transplanted follicles, and complement the surgical result by slowing down or stopping further hair loss.

[source] Donor Harvesting: A New Approach to Minimize Transection of Hair FolliclesDERMATOLOGIC SURGERY, Issue 4 2000Damkerng Pathomvanich MD Background. There are several methods for harvesting donor hairs, including punch excision, single-bladed knife excision, and multibladed knife excision. All of these procedures are blind and thus result in transection of hair follicles. Transection of hair follicles during harvesting results in fewer follicles being available for transplantation, detrimentally affecting the final cosmetic result. Objective. To explore a new method of donor hair harvesting called "donor dissecting." This new procedure is an open technique because hair follicles are directly visualized during the harvesting process. Methods. The technique of donor dissecting utilizes a #15 scalpel blade to excise the donor hair ellipse from the occiput while maintaining meticulous hemostasis. This enables individual hair follicles to be visualized and protected from transection during the harvesting process. Once the donor ellipse is harvested, it is then further divided into individual mini- and micrografts using direct visualization of individual follicles to again prevent transection. Results. The technique of donor dissecting was utilized in 50 consecutive hair transplant patients. Utilizing this new technique, only 1.9% of hair follicles in the donor ellipse were transected during the harvesting process. The dissection of the donor ellipse 1.2% follicles being transected in the graft cutting process. Combining the donor dissection technique with dissection of the individual grafts, we were able to transect 1.59% of hair follicles harvested for transplantation. Conclusion. The technique of donor dissection minimizes the transection of hair follicles in the donor hair harvesting phase of hair transplantation. This technique is superior to the blind methods of donor harvesting which have been plagued by the problem of hair follicle transection.
