Face lift and hair transplantation as a single procedure.

Frequently, when a face lift procedure is performed, several pieces of healthy scalp are discarded as waste unless a prehairline incision is used. In selected cases, such as patients with hair loss, these pieces of scalp may be used to create micrografts (grafts with 1 to 2 hairs) and minigrafts (grafts with 3 to 4 hairs) and transplanted to the areas of need in the same session. I have found particularly rewarding the combination of face lift and hair transplantation, because patients who need both procedures benefit immensely by doing them together. This way, the pieces of healthy scalp that normally would have gone to waste are recycled. In a preliminary fashion, a strip of retroauricular and occipital scalp that normally would be discarded is harvested from one side and handed to my assistants. Under magnification, they dissect it into micrografts and minigrafts as I do the face lift on that side. When I go to the second side of the face lift, I give them the other strip of scalp; again, as they dissect it into grafts, I continue with the face lift. Usually, we generate about 1000 micrografts and minigrafts from those strips that would have normally been discarded. If I want more grafts, I would (in a preliminary fashion) harvest the donor strip of the size required. As the face lift with or without eyelids is completed, we usually have the grafts ready for insertion. Today, we are able to transplant approximately 1000 grafts in about 1 hour. Therefore, combining the two procedures adds only about an hour to our surgical and anesthesia time.     

Immediate hair transplantation into a newly closed wound to conceal the final scar on the hair-bearing skin

A surgical incision after suturing usually leaves a visible scar on the hair-bearing skin, even after optimal wound conditions. The conspicuousness of such a scar results from its linear continuity and hairlessness. To prevent this effect, a row of micrografts or minigrafts was inserted between the wound edges immediately after wound closure. The hair grafts that were transplanted were dissected from the discharged skin in the same surgical procedure, if feasible. Otherwise, a mini donor strip was harvested from the mastoid scalp to dissect the hair grafts. The final linear scar was interrupted and concealed sufficiently with the growth of the transplanted hairs. Tension-free closure is required to obtain a satisfactory result with this technique.     

Correction of the cornrow hair transplant and other common problems in surgical hair restoration

Hair on a man's head is an important emblem of health, youth, and vitality. As in all areas of cosmetic surgery, the refinements of surgical technique and instrumentation have improved the results of hair transplantation. The state of the art in hair grafting today produces a result that is undetectable as being a surgical hair transplant. Many earlier techniques of plug hair transplantation are not aesthetically acceptable by today's standards. This is especially true in the face of progressive hair loss, which can unmask previously camouflaged cornrow plugs. A technique to reduce the plugs and recycle the grafts into smaller grafts is described. The recycled hair grafts can be combined with scalp lifting, scalp reductions, and occipital harvesting of grafts to improve the results of cornrow appearing hair transplants and other problems of surgical hair restoration.     

Progenitor-cell-enriched micrografts as a novel option for the management of androgenetic alopecia

Regenerative medicine is a multidisciplinary field that combines engineering and life science principles to promote regeneration, potentially restoring the physiological condition in diseased tissues. Specifically, the developments of complex grafts enhance the intrinsic regenerative capacity of the host by altering its environment. Autologous micrografts obtained through Rigenera® micrografting technology are able to promote derma and bone regeneration. Androgenetic alopecia (AGA) leads to a progressive thinning of scalp hair affecting 60–70% of the adult population worldwide. Pharmacological treatment offers moderate results and hair transplantation represents the only permanent treatment option. The aim of this study was to demonstrate the role of dermis micrografting in the treatment of AGA by clinical and histological evaluations after 4, 6, and 12 months. Hair growth and density were improved at all indicated times. Those outcomes were also confirmed by the TrichoScan® analysis, reporting an increase of total hair count and density with an increase and reduction of anagen and telogen phases, respectively. Scalp dermoscopic analysis showed an improvement of hair density and histological analysis indicated a clear amelioration of the scalp, development of hair follicles, and a beginning of cuticle formation. Collectively, those results suggest a possible use of the micrografts as a novel therapeutic option in the management of AGA.     

Algorithm of hair restoration surgery in children

Hair is an inseparable element of external appearance of every human being. Although various fashion trends come and go, the lack of hair is for many a major aesthetic and psychological problem. Even if men's balding can be accepted as a natural phenomenon, hair loss in children is considered to be a condition demanding correction. During an 18-year period, 8440 hair restoration operations were performed at the Hair Clinic Poznan, in Poznan, Poland. Most patients were men treated for androgenic alopecia. Among the patients were 57 children in whom hair loss resulted from hereditary factors, perinatal traumas, radiotherapy, and mechanical, thermal, and chemical damage. Methods of restoration were adjusted to type of hair loss, patient age, and ability to cooperate with the surgeon. In cases of single massive scars, skin flap correction was usually used. The flaps were prepared with the use of expanders. In cases of numerous scattered defects or considerable thinning of the scalp, the method of choice was hair transplantation. The "four-hand stick-and-place" technique developed by the authors enabled the surgeon to quickly and precisely carry out the procedure. Application of varied surgery techniques in scalp reconstruction procedures in children gave very good aesthetic results with a minimal complication rate.     

Hair transplantation for men with advanced degrees of hair loss

In the field of surgical hair restoration, there is probably no greater challenge than treating the individual with advanced male pattern hair loss. Recent developments in follicular unit grafting and recognition of the natural appearance of the transplanted frontal forelock have now made it possible to obtain excellent, undetectable results in these patients. Over a 22-month period, the onset correlating with the time when the author began to use the technique of follicular unit grafting, 61 of 322 hair transplant procedures (approximately 20 percent) performed for male pattern hair loss were on men with, or at high risk of developing, advanced male pattern hair loss. Uniformly, the creation of some type of frontal forelock provided excellent results and high patient satisfaction. The concept of the frontal forelock is not new. Developments in aesthetic principles, enhanced understanding of its applicability, and the applied advantages of follicular unit grafting allow for the first time, truly undetectable results.     

Applications of the classic dermal fat graft in primary and secondary facial rejuvenation

Volumetric facial aging occurs primarily as a descent of facial soft tissues, followed by their secondary atrophy. Proper volumetric facial rejuvenation, therefore, demands effective superior redistribution of fallen soft tissues, for which the author prefers malar imbrication. Only then do augmentative adjustments become appropriate, including solid facial protheses, "soft-tissue" fillers, dermal fat grafts, free-fat micrografts, and Erol's "tissue-cocktail." Of these, the author prefers the time-honored dermal fat graft for all primary volumetric augmentations within the surgical field, reserving free-fat micrografts for adjustments outside the field and those performed secondarily. Dermal fat grafts are added to the face in three categories: "camouflage" grafts from the anterior face lift discard specimen to correct contour irregularities in the sculpted subcutaneous cheek in half of patients; "transition" grafts from the suprapubic abdomen to the zone between the midface and lower face in 5 percent of patients with an emaciated quality to their aging; and "secondary" grafts from the abdomen in occasional patients with volumetric deformities following inexpert face lift and other forms of trauma. All grafts were harvested, prepared, and placed according to 10 straightforward technical principles. The grafts were highly effective and predictable in their ability to augment contour; none of 283 total grafts were regarded as a treatment failure. The use of such grafts was extremely safe, with complications limited to cyst formation in 1.5 percent of grafts, all of which were treated nonoperatively. The use of the dermal fat graft is seen as safe, effective, and convenient when the subcutaneous plane of the face is exposed during facial rejuvenation. The majority of grafts were derived from the face lift discard specimen. Although those that came from outside the head and neck presented extra inconvenience and operative time, their use was limited to occasional and challenging circumstances that justified extra investment.     

Cicatricial eyebrow reconstruction with a dense-packing one- to two-hair grafting technique

Scarring eyebrow loss is usually repaired with a hair-bearing island scalp flap or scalp strip grafting technique. The results, however, are usually not desirable with regard to appearance. In this article, a one- or two-hair graft with a dense-packing technique was developed for cicatricial eyebrow reconstruction. It was carried out by harvesting a scalp strip close to the hairline of the back, then dividing it into a series of one- or two-hair grafts, and finally implanting the grafts into the prepared recipient holes of the eyebrow with a desired hair direction. With the authors' experience in treating 96 patients (154 eyebrows) in cases of burn, skin grafting, traumatic scarring, and chemical peeling scar after tattoo removal, the eyebrows could be restored in only one session. In general, 150 to 200 grafts with 200 to 250 hairs were needed for a complete male eyebrow reconstruction and 100 to 150 grafts with 150 to 200 hairs were needed for a complete female eyebrow reconstruction. The maximal hair density was 91.5 hairs/cm per session. Over a 6-month follow-up period, the mean graft survival rate reached 98.1 percent. All of the patients achieved satisfactory results, with a very natural appearance. These results indicate that the above-mentioned technique could be a practical, effective, and probably ideal method for cicatricial eyebrow reconstruction.     

Merkel cell distribution in human hair follicles of the fetal and adult scalp

The distribution of Merkel cells in fetal and adult terminal hair follicles of human scalp was studied immunohistochemically using cytokeratin (CK) 20 as a specific Merkel cell marker. In hair follicles of adult scalp, abundant Merkel cells were found enriched in two belt-like clusters, one in the deep infundibulum and one in the isthmus region. No Merkel cells were found in the deep follicular portions including the bulb, or in the dermis. In early fetal hair follicles (bulbous peg stage), Merkel cells were only detected in the basal layer of the developing infundibulum but not in deeper follicular areas. In later stages, Merkel cells were also present in the isthmus and bulge. No Merkel cells were seen in the dermis around developing hair follicles. Nerve growth factor receptor was not only present in nerves but was found to be widely distributed within fetal skin. In adult skin, this receptor was localized to the basal cell layers of the outer root sheath of the bulb and the suprabulbar area, but was not detectable in the areas containing Merkel cells. The present study localizing Merkel cells within the permanent hair follicle structures close to their possible stem cells suggests that they have paracrine functions.     

The versatile temporoparietal fascial flap: adaptability to a variety of composite defects

The unique properties of the temporoparietal fascial flap (TPFF) offer adaptability in reconstruction of a variety of composite defects. The broad, thin sheet of vascularized tissue may be transferred alone or as a carrier of subjacent bone or overlying skin and scalp. As a pedicled flap, it is ideal for defects of the orbital, malar, mandibular, and mastoid regions. As a free-tissue transfer, the large vessels and lack of bulk find broad utility in reconstruction of the extremities. This flap is our choice for reconstruction of the dorsal hand and non-weight-bearing surfaces of the foot. A viscous gliding surface decreases friction for tendon excursion. The thin contour is aesthetically superior to thicker flaps, allowing unmodified footwear or gloves. The pliable fascia convolutes into surface defects (e.g., bone craters) or drapes over skeletal frameworks (e.g., ear cartilage). The rich capillary network offers nutrition to saucerized bone, cartilage or tendon grafts, and overlying skin grafts. The geometry of the skull lends to fabrication of membranous bone for complex facial puzzles. The donor site is well disguised by hair growth. Twelve cases performed over a 2-year period demonstrate the versatility of this flap. These include complex foot reconstruction, ear and scalp avulsion, shotgun wound of the cheek and orbit, posttraumatic jaw recontouring, chronic osteomyelitis of the hand and foot, and acute resurfacing of dorsal hand with tendon reconstruction.     

Early definitive bone and soft-tissue reconstruction of major gunshot wounds of the face

The use of craniofacial surgical techniques, extended open reduction, rigid fixation with plates and screws, and the replacement of severely damaged or missing bone with immediate bone grafting in the treatment of complex facial fractures has been applied to the management of severe gunshot wounds of the face. Early definitive bone and soft-tissue reconstruction has been performed in 37 patients. One-hundred and seventy-seven primary bone grafts were utilized in 33 patients for orbital, nasal, zygomatic, and maxillary reconstruction. Twenty-six patients required mandibular repair with compression or reconstruction plates. Soft-tissue reconstruction was provided by a combination of flaps. Four patients had extensive soft-tissue loss replaced by free vascularized omental flaps. The omentum provided circumferential coverage of the mandibular reconstruction and reconstruction of the floor of the mouth and was then tunneled in a circle through both cheeks into the middle and upper face. The omentum reconstructed deficits in the hard palate and upper buccal sulcus and was then wrapped around all zygomatic, orbital, and midfacial bone grafts and used to fill in dead space in the maxillary, ethmoid, and frontal sinuses. The omentum is not used to provide contour and bulk, but to cover bone grafts and plates and fill in dead space. Carefully shaped bone grafts provide the correct craniofacial scaffold. Early restoration of a midfacial bony scaffold and the prevention of soft-tissue contraction facilitate secondary reconstruction. Four late total nasal reconstructions with tissue-expanded forehead skin wrapped around bone grafts were performed.     

Brief communication: Choice of washing method of hair samples for trace element analysis in environmental studies.

Determination of inseparable exogenous and endogenous levels of toxic trace elements such as lead in human scalp hair has been used to understand and assess population exposure to such elements. For any such analysis, washing of the hair samples to remove superficial contamination is the foremost requirement. However, the use of such washing methods prior to elemental analysis removes minute quantities of trace elements from the hair strands. This degree of loss is dependent on the washing method employed. In the present study, the element lead has been determined in human scalp hair after three methods of hair washing. It is apparent that the nonionic detergent-acetone method is best suited for securing valid lead analysis results in human scalp hair.     

A new composite facial and scalp transplantation model in rats

There are limited sources of autogenous tissue available for reconstruction of severe facial and scalp deformities caused by extensive tumor ablation, burns, or trauma. Allografts from cadaveric sources may serve as a reconstructive alternative. However, technical and immunological aspects of harvesting and transplanting face and scalp flaps limit the routine use of such procedures. For evaluation of the feasibility of composite-tissue reconstruction, an experimental model of composite face/scalp flap transplantation in rats was designed. Technical aspects of the model, survival rates, and the complications encountered during development of the model are presented. A total of 64 animals, in three experimental groups, were studied. In group I, the anatomical study group (n = 6), the anatomical features of the face and scalp region in rats were explored. Groups II and III were the transplantation groups. Isograft transplantations were performed between identical Lewis rats (RT11 to RT11), and allografts were transplanted, across major histocompatibility complex barriers, between Lewis-Brown Norway rats (RT1l/n) and Lewis rats (RT11). In group II (the control group, n = 8), transplantation of nonvascularized composite face/scalp isografts and allografts was performed. In group III (the transplantation group, n = 50), vascularized face/scalp isografts (n = 36) and allografts (n = 14) were transplanted. Complications included partial or total flap necrosis, death attributable to food aspiration, and poor general condition. To prevent acute and chronic allograft rejection, cyclosporine A (16 mg/kg per day) therapy was initiated 24 hours after transplantation; the dose was tapered to 2 mg/kg per day within 4 weeks and was maintained at that level thereafter. Long-term survival (>170 days) was achieved, without any signs of rejection, with low-dose (2 mg/kg per day) cyclosporine A therapy. This is the first report documenting successful composite face/scalp flap transplantation in the rat model.     

Effect of Scalp and Facial Hair on Air Displacement Plethysmography Estimates of Percentage of Body Fat

Objective: The objective of this study was to determine the effect of body hair (scalp and facial) on air displacement plethysmography (BOD POD) estimates of percentage of body fat. Research Methods and Procedures: A total of 25 men (31.4 ± 8.0 years, 83.4 ± 12.2 kg, 181.8 ± 6.9 cm) agreed to grow a beard for 3 weeks to participate in the study. Total body density (g/cm³) and percentage of body fat were evaluated by BOD POD. To observe the effect of trapped isothermal air in body hair, BOD POD measures were performed in four conditions: criterion method (the beard was shaven and a swimcap was worn), facial hair and swimcap, facial hair and no swimcap, and no facial hair and no swimcap_. Results: The presence of only a beard (facial hair and swimcap) resulted in a significant underestimation of percentage of body fat (16.2%, 1.0618 g/cm³) vs. the criterion method (17.1%, 1.0597 g/cm³, p < 0.001). The effect of scalp hair (no swim cap worn) resulted in a significant underestimation in percentage of body fat relative to the criterion method, either with facial hair (facial hair and no swimcap; 14.8%, 1.0649 g/cm³) or without facial hair (no facial hair and no swimcap; 14.8%, 1.0650 g/cm³, p < 0.001 for both). Discussion: A significant underestimation of percentage of body fat was observed with the presence of facial hair (～1%) and scalp hair (～2.3%). This underestimation in percentage of body fat may be caused by the effect of trapped isothermal air in body hair on body‐volume estimates. Thus, excess facial hair should be kept to a minimum and a swimcap should be worn at all times to ensure accurate estimates of body fat when using the BOD POD.     

A new and simple way to clear the hair from operating fields in the scalp.

The McGivney instrument has been designed for rubber band ligation of hemorrhoids. A simple way to clear the hair from the operating field with the aid of this device during surgery on the scalp is described. The method has been found to be quick and easy, and the tuft of hair is also held in a firmer position than with other methods used for this purpose.     

Hair transplantation in alopecia due to radiation

Two cases of alopecia due to radiation of the scalp are presented in which it has been possible to achieve a technically and cosmetically satisfactory reconstruction by punch hair grafting. This does not mean that every case is suitable, but it does mean that those without contraindications should at least be given a try.     

Engraftment and differentiation of embryonic stem cell-derived neural progenitor cells in the cochlear nerve trunk: growth of processes into the organ of Corti

Hearing loss in mammals is irreversible because cochlear neurons and hair cells do not regenerate. To determine whether we could replace neurons lost to primary neuronal degeneration, we injected EYFP-expressing embryonic stem cell-derived mouse neural progenitor cells into the cochlear nerve trunk in immunosuppressed animals 1 week after destroying the cochlear nerve (spiral ganglion) cells while leaving hair cells intact by ouabain application to the round window at the base of the cochlea in gerbils. At 3 days post transplantation, small grafts were seen that expressed endogenous EYFP and could be immunolabeled for neuron-specific markers. Twelve days after transplantation, the grafts had neurons that extended processes from the nerve core toward the denervated organ of Corti. By 64-98 days, the grafts had sent out abundant processes that occupied a significant portion of the space formerly occupied by the cochlear nerve. The neurites grew in fasciculating bundles projecting through Rosenthal's canal, the former site of spiral ganglion cells, into the osseous spiral lamina and ultimately into the organ of Corti, where they contacted hair cells. Neuronal counts showed a significant increase in neuronal processes near the sensory epithelium, compared to animals that were denervated without subsequent stem cell transplantation. The regeneration of these neurons shows that neurons differentiated from stem cells have the capacity to grow to a specific target in an animal model of neuronal degeneration.     

The temporal island scalp flap for management of facial burn scars

Facial burn scars are difficult to conceal and often preclude an aesthetic rehabilitation of the patient. Multistaged scalp and neck flaps have been described to provide hair-bearing skin to resurface burn scars in men. We have been resurfacing the upper lip and cheek in a one-stage procedure using a temporal artery island scalp flap. The temporoparietal fascia has been well described in recent years, and the understanding of this anatomy has facilitated the use of the island scalp flap for more distal transfers.     

The extended V-Y flap.

The extended V-Y flap is a modification of the V-Y advancement flap, which is very useful in closing defects following excision of facial lesions. The modification involves the addition of an extension limb onto the advancing edge of the standard flap. This limb is located adjacent to the area requiring reconstruction and is hinged down as a transposition flap on the end of the V-Y advancement flap to close the most distal portion of the defect. The extended V-Y flap has been found to be very effective in closing large defects in areas that typically have inadequate subcutaneous tissue to allow extensive mobilization of the standard V-Y advancement flap. It has been used effectively with excellent cosmetic results in the temporal, scalp, forehead, and nasal areas, providing a well-contoured and aesthetically pleasing reconstruction.
