Thuangtong R, Suthakorn J. Design, proof-of-concept of single robotic hair transplant mechanisms for both harvest and implant of hair grafts. Comput Struct Biotechnol J 2024; 24:31-45. [PMID: 38162956 PMCID: PMC10755542 DOI: 10.1016/j.csbj.2023.11.051] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2023] [Revised: 11/27/2023] [Accepted: 11/27/2023] [Indexed: 01/03/2024] Open
Abstract
The design and development of a prototype for a singular robotic hair transplant system capable of harvesting and implanting hair grafts were executed in this study. To establish a proof-of-concept for hair transplant procedures involving harvesting and implantation, a test system using a spherical phantom of the scalp was selected. The developed prototype of the robotic hair transplant system demonstrates the potential to reduce the duration that grafts remain without a blood supply, thereby minimizing hair graft damage. Additionally, the overall operation time for follicular unit extraction is comparatively shorter than that of conventional systems. Results from the robot vision tests indicate an 89.6% accuracy for hair graft detection with a 4 mm hair length phantom and 97.4% for a 2 mm hair length phantom. In the robot position control test, the root mean square error was found to be 1.268°, with a standard error of the mean of 0.203°. These outcomes suggest that the proposed system performs effectively under the conditions of a spherical phantom with a 2 mm hair length and a 5 mm distance between harvests.

Abstract
BACKGROUND Follicular unit hair transplantation has greatly elevated the results of eyebrow restoration. However, unnatural and unbeautiful-looking results are still often seen after the surgery. OBJECTIVES This study focused on poor eyebrow transplantation, discussed its possible reasons, and offered refined proposals. METHODS A retrospective analysis was performed on 100 patients who were dissatisfied with the results of eyebrow grafting and came to our department from 2011 to 2021. Demographic characteristics, primary disease, and clinical data were objectively summarized and analyzed for these patients. RESULTS The patients' medical charts and photographs were analyzed and summarized into the following outcomes: Thirty-six patients (36%) had sparse eyebrows. Forty-one patients (41%) had eyebrows with inhomogeneous density and disordered growth direction. Eleven patients (11%) did not have single-hair grafting. Seven reconstructed eyebrows (7%) had a poor connection with the remaining eyebrows. Five new eyebrows (5%) had inconsistent hair characteristics with the original eyebrows. Lower hair survival rates, insufficient understanding of naturally beautiful eyebrows, and inadequate communication with patients were the main reasons for poor outcomes. CONCLUSIONS Good reconstructed eyebrows should have a high hair survival rate, and hair growth direction and characteristics should also be consistent with the natural eyebrow to achieve ideal surgical effects.

Abstract
Androgenetic alopecia can be challenging to treat due to the wide range of available treatments, most of which are not based on evidence from clinical trials. In addition many of the options do not include androgenetic alopecia among the approved indications according to their summaries of product characteristics. A panel of 34 dermatologists from the Spanish Hair Disorders Society of the Spanish Academy of Dermatology and Venereology (AEDV) used the Delphi method to develop a consensus statement on the management of androgenetic alopecia. Over a 2-round process the experts agreed on 138 (86%) of the 160 proposed items, which were structured into 4 blocks of recommendations: general considerations, pharmacologic treatment, procedures and hair transplant, and special cases. The resulting consensus statement based on expert opinion of the scientific evidence can guide professionals in the routine management of androgenetic alopecia.

Abstract
AIM To achieve international expert consensus and give recommendations on best practices in hair transplantation surgery, focusing on pre- and post-transplantation care. METHODS A modified Delphi method was used to reach consensus. An international scientific committee developed an 81-statement questionnaire. A panel of 38 experts in hair transplantation from 17 countries across 4 continents assessed the questionnaire. RESULTS Two consensus rounds were carried out, with 59 out of 81 statements (73%) reaching consensus. Expert recommendations emphasize the correct selection of candidates for hair transplantation and the need for patients to have received adequate medical treatment for alopecia before transplant. Comorbidities should be assessed and considered while planning surgery, and an individualized plan for perioperative care should be drawn up before transplant. Certain medications associated with increased risk of bleeding should be withdrawn before surgery. Specific recommendations for post-transplantation care are given. After transplantation, patients should gradually resume their normal haircare regimen. Close follow-up should be carried out during the first year after transplant. CONCLUSIONS This study presents numerous consensus-based recommendations on general aspects of hair transplantation, including candidate selection, medical therapy prior to transplantation, anesthesia, and resuming haircare after transplantation.

Abstract
Abstract
Background
Pattern hair loss is a common disorder in female and male subjects that may benefit from the use of cell-free XoFlo (Direct Biologics, LLC, Austin, TX) therapy.
Objectives
To assess the safety, efficacy and satisfaction of a single extracellular vesicle (EV) treatment over 6 months.
Methods
A retrospective open-label study among 22 female and 9 male subjects who demonstrated early stages of alopecia or were in remission from prior medical and surgical treatments. The amount of undiluted or diluted volumes of EV solution used was determined by extent and degree of alopecia. Global photography, SGAIS and IGAIS questionnaires, and trichoscan measurements were compared at baseline and six months in three response categories.
Results
Frequent growth responses were observed: older aged females and younger aged males, shorter history of alopecia; earlier stages of hair loss; larger and undiluted volumes of XoFlo; prior positive responses to medical and surgical treatments; and absence or control of disease factors affecting hair. The benefit of micro-needling to therapy was indeterminate. Global photography, trichoscan for density, follicle diameter, terminal: vellus ratio, and SGAIS/IGAIS satisfaction questionnaires at baseline and six months were useful in assessing clinical efficacy. No significant adverse reactions were observed.
Conclusions
Intradermal injections with varying doses of EVs were safe and effective among indicated alopecic female and male subjects. Findings suggest that the presence of positive factors, absence of conditions known to negatively affect hair growth, and administration of larger volumes of XoFlo may have a significant influence on the use of this new cell-free therapy. FDA-approved biologic, multi-centered IRB/ Investigational New Drug (IND) trials are clearly required to determine its future in the management of hair loss.

Abstract
BACKGROUND Surgical management of hair loss has become an increasingly challenging procedure, when dealing with scar alopecia. We investigated the efficacy of hair transplantation in patients with head and neck scar alopecia. METHODS From 2016 to 2018 in Shiraz, Iran, all patients with scar alopecia in head and neck were evaluated for efficacy of follicular unit extraction (FUE), follicular unit transplantation (FUT) or a combination of two methods from donor sites in scalp and beard various hair-grafts were compared. RESULTS Fifty-six patients were enrolled. Most of them were between 31 and 40 yr old (48.3%) and male (71.4%). Trauma, burn, surgical excision of adjacent skin, radiotherapy and leishmaniasis were the registered causes. Scars were visible in scalp (39.3%), beard (28.6%), eyebrow (21.4%), and moustache (10.7%) regions. FUE (87.5%), FUT (10.7%) and a combination (1.8%) were the used methods. One-hair-grafts were used in eyebrows (100%), moustache (100%), beard (88%) and scalp (7.9%), while 2-hair-grafts in beard (6%) and scalp (47.4%) and 3-haired grafts in beard (6%) and scalp (44.7%) transplantations. CONCLUSION In head and neck scar alopecia, hair transplantation was selected based on type and depth of scar. FUE was targeted when huge grafts were not needed, including beard, moustache, and eyebrow, while FIT was used when extensive scars were present in scalp. One-hair-grafts were mostly applied for eyebrow, moustache and beard, 2-hair- and 3-hair- grafts for beard and scalp transplantation. These findings can be added to the literature when FUE, FIT, or their combination are targeted in hair restoration of scar alopecia in head and neck.

Abstract
Objective This study aims to establish the concept of invalid extraction rates in follicular unit extraction and evaluate its clinical value. Methods The present study involved 30 patients with alopecia. Three young surgeons (nominated A, B, and C) each performed follicular unit extraction on a randomly selected portion of the donor site of each patient for ten minutes. The outcomes were separately recorded and calculated, and converted to an invalid extraction rate for each surgeon using the formula, “invalid extraction rate = 1 − successfully extracted follicular units/actually extracted units × 100%.” Results The follicular unit invalid extraction efficiency of each surgeon gradually declined. The average efficiency level of surgeon B was evaluated as excellent, while the levels of surgeons A and C were evaluated as good. Conclusion With experience, surgeons can speed up the process of follicular unit extraction and gradually increase performance quality through both extraction speed and success rate.

Abstract
Introduction Insufficient hair growth after hair transplant, as well as erythema and perifollicular scaling, may be diagnosed as lichen planopilaris and treated as such based on clinical and histopathological findings. The purpose of this study is to observe graft biopsies of patients after uncomplicated hair transplants and to discuss if histological findings are enough to diagnose lichen planopilaris. Methods and Results Eight patients diagnosed with androgenetic alopecia who were submitted to hair transplant were enrolled. In each of the participants, a scalp biopsy was performed in the receptor area and in the adjacent area. Biopsies were performed between 6 months and 1 year after surgery. Exams were analyzed by 3 pathologists. The t test was performed for paired observations, comparing the transplanted and the nontransplanted area for lymphocytic infiltrate and fibrosis. The significance level was considered as 5% (p < 0.05). Four of 8 participants had perifollicular lymphocytic infiltrate, from moderate to dense intensity in the recipient area. Fibrosis was seen in 6 patients. These findings were not seen in the control area. Conclusions It is questioned whether lymphocytic infiltrate and fibrosis may be expected in patients who are submitted to normal hair transplants.

Abstract
Premature graying of hair (PGH) being a very common entity for which pharmacotherapy and reversibility are not properly addressed. Therefore, this systematic review was conducted to address these issues. For this relevant study were selected from various databases including PubMed, EMBASE, OVID, Web of science, Scopus, and Google Scholar till January 20, 2019. Studies which reported risk factors, co-morbid conditions associated with PGH, its pharmacotherapy and reversal were included in the study. Although many risk factors are reported in literature, smoking, vitamin deficiency (B12, folic acid, and B7), mineral deficiency (low serum calcium and serum ferritin) are found to be associated with PGH. Other important risk factors are family history of PGH, obesity, high B.P, lack of exercise, drugs, genetic syndromes, dyslipidemia, thyroid disorders, hyperuricemia, and alteration in liver function. PGH is found to be an important marker of CAD, more so in case of smoker. Among different pharmacotherapeutic management options, low grade recommendation (2A) is given to calcium pantothenate, PABA, calcium pantothenate + PABA combination. Anu-tailam is the only herbal agent evaluated in clinical research settings. Finally, treating the accompanying pathologies led to the reversal of the disease in many cases.

Abstract
BACKGROUND The incidence of hair loss among Chinese male has increased to 21.3 per hundred. Hair restoration has been an effective technique. Detailed hair distribution has a tremendous impact on the surgery design. OBJECTIVE To investigate the pattern of hair distribution in Chinese young adult males. METHODS A total of 1000 males without hair disease were enrolled. We evaluated the locations of the main anatomical marks at different sites on the scalp and analyzed the hair density and follicular unit structure using the standard photographs and trichoscope. RESULTS The hairline shapes were classified as: linear (48.7%), linear with central protrusion (27.9%), round (9.8%), round with central protrusion (13.7%). The average height of the median line was 6.78 ± 0.75 cm, the ratio of the median line and the forehead height was 0.333. The average distance from the parietal whorl to the vertical bimeatal line was 7.05 ± 3.32 cm, and most of the PWs were on the right (51.4%) and had a clockwise pattern (73.3%). The hair density was 171.12 ± 18.32 hairs/cm in the vertex. 1-hair follicular units were (75.90% and 56.39%) in anterior hairline and temporal area. CONCLUSION Our study clearly assisted understanding of scalp anatomy and hair distribution in Chinese young adult males.

Abstract
Background The most infallible approach to male pattern baldness (MPB) is hair transplantation in the thinning area in parallel to medical treatment to prevent further alopecia progression. For an individual with advanced stage hair loss, a megasession surgery is recommended to meet the high donor hair requirement. Yet a most effective therapeutic regimen for alopecia, hair transplantation inevitably has its advantages and disadvantages for it is done with the expense of donor hair sacrifice, intraoperative and postoperative pain, and unavoidable scars. Also, with poor donor condition, surgery may not even be an option. Nowadays, more patients with such limitations are undergoing shaved style scalp medical tattoo (SMT). Objective To assess the effectiveness of SMT technique for shaved hair style. Methods and materials A total of 80 patients who were included in the study underwent SMT for shaved hair style between June 2014 and June 2017 and were followed for at least 6 months afterward. Patients and the surgeon completed a survey about donor and recipient site surgical results using a 5‐point Likert scale. Results The average satisfaction scores of patients and surgeon were 4.8 and 4.9, respectively. Conclusion Shaved style SMT can be considered one of the most effective treatment methods for patients with advanced stage hair loss. Level of evidence IV.

Abstract
Male sex hormones-androgens-regulate male physique development. Without androgen signaling, genetic males appear female. During puberty, increasing androgens harness the hair follicle's unique regenerative ability to replace many tiny vellus hairs with larger, darker terminal hairs ( e.g., beard). Follicle response is epigenetically varied: some remain unaffected ( e.g., eyelashes) or are inhibited, causing balding. How sex steroid hormones alter such developmental processes is unclear, despite high incidences of hormone-driven cancer, hirsutism, and alopecia. Unfortunately, existing development models are not androgen sensitive. Here, we use hair follicles to establish an androgen-responsive human organ culture model. We show that women's intermediate facial follicles respond to men's higher androgen levels by synthesizing more hair over several days, unlike donor-matched, androgen-insensitive, terminal follicles. We demonstrate that androgen receptors-androgen-activated gene transcription regulators-are required and are present in vivo within these follicles. This is the first human organ that involves multiple cell types that responds appropriately to hormones in prolonged culture, in a way which mirrors its natural behavior. Thus, intermediate hair follicles offer a hormone-switchable human model with exceptional, unique availability of genetically identical, but epigenetically hormone-insensitive, terminal follicles. This should enable advances in understanding sex steroid hormone signaling, gene regulation, and developmental and regenerative systems and facilitate better therapies for hormone-dependent disorders.-Miranda, B.

Abstract
BACKGROUND There is little information about how hair diameter differences within the safe donor area. Thicker or thinner hair may be needed depending on the recipient area, hairline design, and surgical purpose. METHODS Thirty-eight non-alopecic subjects (19 males and 19 females) were evaluated. The safe donor area was defined as the area contained within 28 cm from the horizontal plane of the upper border of the hair rim to the vertical line of the bilateral external acoustic meatus. Seven zones were defined starting 2 cm on each side (bilateral 4 cm) from the mid-occiput to the temporal side. The diameters of 10 randomly selected anagen hairs were measured from each of the seven zones. RESULTS The results showed significant differences in hair diameter by zone between males and females (P < 0.0001). In general, hair diameter tended to decrease from zone 3 to 7. CONCLUSION Our results suggest that safe donor areas between zones 4 and 7 could be useful for specific hair transplantation surgeries requiring thinner hair, such as eyebrows, eyelashes, and female hairline correction surgery, whereas hair from zones 1-3 could be more useful for those requiring thicker hair, such as male and female pattern hair loss. Our data could be clinically valuable for planning hair transplant surgery and choosing the most optimal donor region.

Abstract
Fabrication of an orbital prosthesis is considered as a challenging procedure as compared to the other facial prosthesis due to the presence of inactive eye movements and the need of artificial hair in order to mimic eyelashes and eyebrows. Generally these structures are sewed or bonded in the silicone. However, deformation or hair loss is observed within time. This deformation is visible especially in the eyebrow. This clinical report represents a patient with an implant supported orbital prosthesis. Patient was not satisfied with the nature of her eyebrow that was sewed in the silicone. Therefore, an alternative approach of eyebrow transplantation was used for the patient. The patient expressed her better satisfaction of this definitive prosthesis supported with eyebrow transplantation.

Abstract
Facial plastic surgery is a multidisciplinary specialty largely driven by otolaryngology but includes oral maxillary surgery, dermatology, ophthalmology, and plastic surgery. It encompasses both reconstructive and cosmetic components. The scope of practice for facial plastic surgeons in the United States may include rhinoplasty, browlifts, blepharoplasty, facelifts, microvascular reconstruction of the head and neck, craniomaxillofacial trauma reconstruction, and correction of defects in the face after skin cancer resection. Facial plastic surgery also encompasses the use of injectable fillers, neural modulators (e.g., BOTOX Cosmetic, Allergan Pharmaceuticals, Westport, Ireland), lasers, and other devices aimed at rejuvenating skin. Facial plastic surgery is a constantly evolving field with continuing innovative advances in surgical techniques and cosmetic adjunctive technologies. This article aims to give an overview of the various procedures that encompass the field of facial plastic surgery and to highlight the recent advances and trends in procedures and surgical techniques.

Abstract
Background Sensitive or hyperreactive skin is a common condition defined by prickling, burning, pain, and pruritus. Although this skin problem was initially described on the face, the scalp is often affected. A sensitive scalp can react with irritation to harsh surfactants or other additives which are often present in shampoos. For this reason, we developed a new rinse-off hypertolerant shampoo specifically designed for the hypersensitive and problematic scalp. Methods The shampoo formulation is based on an extremely mild surfactant system and contains bisabolol, an anti-irritant and anti-inflammatory ingredient of chamomile. The shampoo is free of additives such as perfumes, silicones, colorants, parabens, paraffins, and betaine. Since skin can remain in a hyperreactive state after wounding, the status after hair transplantation was chosen as a model system to test the shampoo. Scalp condition and compatibility of each volunteer were analyzed by a plastic surgeon directly after hair transplant and after stitch removal. The plastic surgeons also rated whether they would recommend the further use of the test shampoo. Additionally, volunteers completed a self-assessment questionnaire. Results Following hair transplantation, regular use of the shampoo resulted in a significant reduction in the extent of scabbing and erythema. This was confirmed by dermatological scalp examinations performed by the plastic surgeon as well as in volunteers’ self-assessments. The plastic surgeon highly recommended the further use of the test shampoo after hair transplant to all study participants. Conclusion Application of the test shampoo demonstrated excellent skin compatibility and product efficacy after hair transplant. The test shampoo significantly reduced the extent of scabs and erythema. Therefore, the shampoo is ideally suited for use after hair transplantation and for the treatment of sensitive scalp. The excellent skin compatibility is because of the mild surfactant system, the calming ingredient bisabolol, and the absence of potentially irritating ingredients.

Abstract
BACKGROUND Scarring alopecia resulting from burns may be difficult to treat and involves various plastic surgery techniques such as expanded scalp flaps. OBSERVATION Herein, we report the case of a 19-year-old male patient who suffered burning of the scalp with scarring alopecia following an attack with a Taser(®) electrical gun. Given the extent and site of alopecia, we decided to create a prosthesis by means of scalp expansion. The cosmetic result was satisfactory. DISCUSSION Several scalp reconstruction techniques have been described for scarring alopecia, with the most widely used being expansion, scalp flaps, repeated excision and hair implants. CONCLUSION The present case suggests that scalp expansion offers an effective method for the reconstruction of scarring alopecia following burns with a Taser(®) device.
