RESUMEN

Punch grafting is a technique that can improve and accelerate the healing of hard-to-heal wounds and reduce the associated pain. It is a simple and inexpensive procedure that can be performed in the examination room. It is a technique that uses small split-thickness skin grafts (STSG) to promote the growth of epithelial tissue. It has been described as being used mainly to treat ulcers of venous, arterial, hypertensive and diabetic aetiology. Punch grafting has also been used successfully in postoperative dermatological surgical wounds. This article describes and details the performance of the punch-graft technique, with special emphasis on aftercare and the role of nurses in the procedure. A clinical case is presented of a patient who underwent surgery for cutaneous squamous cell carcinoma and whose primary closure was rejected. It was decided to place the STSGs obtained from the anterior aspect of the patient's thigh after preparation of the recipient area to ensure an optimal wound bed. The patient's pain subsided within a few days, and the wound healed within weeks with weekly dressing changes.

RESUMEN

Abstract Chronic ulcers significantly affect the quality of life of patients and impose a high cost on the healthcare system. The therapeutic management should be comprehensive, taking into consideration the etiological diagnosis of the wound and the characteristics of the wound bed when deciding on a therapeutic proposal appropriate to the healing phase, correcting factors that delay healing. During the epithelialization phase, repair techniques with grafts are recommended to shorten re-epithelialization time, improve the quality of scar tissue, and achieve adequate pain management. Currently, due to the reported benefits of skin appendages, the technique of follicular unit auto-grafting obtained with a scalp punch is among the chosen strategies for wound repair. This is a minimally invasive, outpatient practice, whose technique has advantages over the donor site, patients recovery and well-being.

RESUMEN

Acral melanoma commonly occurs on weight-bearing areas of the sole. Reconstruction of such areas presents a surgical challenge due to limited availability and mobility of local skin. Thus, we aimed to compare the scar outcome of full-thickness skin graft (FTSG) and punch grafting in the reconstruction of plantar defects after melanoma surgery. We retrospectively reviewed six patients who underwent both FTSG for nonweight-bearing areas and punch grafting for weight-bearing areas. We compared results of FTSG and punch grafting within the same patient. Photos of completely healed scars were graded using the Stony Brook Scar Evaluation Scale (SBSES). The averages of the FTSG scores and the punch graft scores, as measured by the SBSES, were statistically compared. Punch grafting yielded a better outcome than FTSG, according to the SBSES. The average of the punch grafting scars was 4.67, which was significantly greater (p = 0.004) than that of FTSG scar scores at 1.83. For weight-bearing areas, punch grafting should be considered as the first option of reconstruction, with FTSG as a second option for nonweight-bearing areas. Overall, this combined approach provides an effective and safe method for reconstruction of extensive plantar wounds.

RESUMEN

Objective: Hairline vitiligo is a special area. Hairy areas within the hairline often require repigmentation and regrowing hair shafts. The face and forehead outside the hairline do not require regrowing hair shafts, only repigmentation. To tackle this issue, we modified the conventional mini-punch grafting with a combined application of mini-punch grafting and follicular hair transplant. Methods: Five patients with localized hairline stable vitiligo aged 26-32 years old had a history of nonsurgical treatments for at least 3 months and without progress. The grafts were transversely sectioned. The intact half follicles were preserved below the cross-section. Sectioned grafts were placed into the chambers for transplanting with forceps. Results: The treatment using transversely sectioned mini-punch grafting with the patient was performed for all five patients, and the results were satisfactory. In the area of the forehead outside the hairline with the sectioned mini-punch grafting above the cross-section, hair loss and repigmentation were observed. In the area of the hairy areas within the hairline, growing hair shafts and repigmentation were observed, without hair loss. Conclusion: Our report can help to manage hairline vitiligo or hairy areas vitiligo. This method can be considered a potential method for the treatment of hairline vitiligo, thus providing a simple solution to complex problems.

RESUMEN

Punch grafting is an alternative treatment to enhance wound healing which has been associated with promising clinical outcomes in various leg and foot wound types. We aimed to evaluate the clinical outcomes of punch grafting as a treatment for hard-to-heal diabetic foot ulcers (DFUs). Six patients with chronic neuropathic or neuroischemic DFUs with more than 6 months of evolution not responding to conventional treatment were included in a prospective case series between May 2017 and December 2020. All patients were previously debrided using an ultrasound-assisted wound debridement and then, grafted with 4 to 6 mm punch from the donor site that was in all cases the anterolateral aspect of the thigh. All patients were followed up weekly until wound healing. Four (66.7%) DFUs were located in the heel, 1 (16.7%) in the dorsal aspect of the foot and 1 (16.7%) in the Achilles tendon. The median evolution time was 172 (interquartile range [IQR], 25th-75th; 44-276) weeks with a median area of 5.9 (IQR; 1.87-37.12) cm2 before grafting. Complete epithelization was achieved in 3 (50%) patients at 12 weeks follow-up period with a mean time of 5.67 ± 2.88 weeks. Two of the remaining patients achieved wound healing at 32 and 24 weeks, respectively, and 1 patient showed punch graft unsuccessful in adhering. The median time of wound healing of all patients included in the study was 9.00 (IQR; 4.00-28.00) weeks. The wound area reduction (WAR) at 4 weeks was 38.66% and WAR at 12 weeks was 88.56%. No adverse effects related to the ulcer were registered through the follow-up period. Autologous punch graft is an easy procedure that promotes healing, achieving wound closure in chronic DFUs representing an alternative of treatment for hard-to-heal DFUs in which conservative treatment has been unsuccessful.

RESUMEN

OBJECTIVE: Martorell hypertensive ischaemic ulcers are often misdiagnosed and can be a clinical and therapeutic challenge. Controversy exists regarding both their underlying triggers and the type of treatment that should be carried out. This study was designed to compare the effectiveness of punch grafting and conventional therapy in pain reduction. METHOD: A single-centre retrospective study was performed, including 40 patients with a clinical diagnosis of a Martorell ulcer or post-traumatic ulcer secondary to arteriolopathy in the elderly, who were treated with punch grafting (n= 24) or conventional medical treatment (n=16). RESULTS: There was a statistically and clinically significant reduction in pain after punch grafting. The minimal overall reduction was of three points in visual analogue pain scores. Of the patients who received punch grafting, 80% reported a VAS pain score of 0 at the third follow-up, in contrast with the 44% (n=4) patients who were treated without punch grafting. The mean time to epithelialisation was 82.1 days in patients who received conventional treatment and 43.5 days in those who received punch grafts. CONCLUSION: Punch grafting is a simple, validated and cost-effective technique that can be performed on an outpatient basis, promotes wound healing and reduces pain. It may control pain and stimulate epithelialisation even if the wound does not present with optimum wound bed characteristics for graft taking. Pain reduction and faster epithelialisation are associated with improvements in patients' quality of life.

RESUMEN

Surgical methods are favorably used for treatment of stable vitiligo, and platelet-rich plasma (PRP) can be added to augment the effect. The additive value of PRP, however, remains elusive. Basic fibroblast growth factor (bFGF) is released from activated platelets with a capacity for stimulating melanocyte proliferation and migration. The treatment outcomes for the mini-punch grafting (MPG)/phototherapy treatment with and without PRP were assessed and the relation between bFGF and the obtained results were evaluated. Thirty-four vitiliginous patches, two per each patient with stable vitiligo, were enrolled in this intrapatient-controlled study and treated with autologous MPG and subsequent exposure to phototherapy with and without enhancement via PRP procedure at the time of the procedure, and monthly for the subsequent 3 months. Re-pigmentation assessment via vitiligo scores as well as measurement of lesional bFGF were done. PRP assistance to MPG/phototherapy treatment resulted in earlier re-pigmentation at week 8. However, this enhancement effect vanished at the study end (week 20) as ideal re-pigmentation (>75% re-pigmentation) was encountered in 10 patches (58.8%) treated with MPG/phototherapy modality, and in 12 patches (70.6%) treated with PRP-assisted method without significant difference between them. Lesional bFGF increased after both treatments with a higher expression with PRP assistance but without clinical reflection on the final outcome. PRP can speed the re-pigmentation response for MPG/phototherapy procedure without any significant effect on the final outcome.

RESUMEN

Dyskeratosis congenita (DC) is an unusual inherited disease characterized by the triad of mucosal leukoplakia, nail dystrophy, and skin pigmentation. Hyperkeratosis of the palms and soles is another reported skin finding. This hyperkeratosis can lead to fissures, chronic erosion, and deep ulcerations. These atypical wounds are not only a diagnostic but a therapeutic challenge for clinicians, and there are no standardized treatments for these types of chronic wounds. Punch grafting is a traditional and minimally invasive technique to enhance wound healing, and it has been associated with significant and quick pain reduction in ulcers with various underlying causes. Herein, we describe a patient with DC with a chronic and refractory plantar ulcer successfully treated with punch grafting.

RESUMEN

Micropunch grafting is the simplest surgical intervention for refractory vitiligo but is tedious and time-consuming. Therefore, we aimed to verify the efficacy and safety of dermal orientation grafting using motorized 0.5-mm micropunch grafting for vitiligo. In a preliminary animal study, 12-week-old rats were used to observe the healing process after the transplantation of dermal orientation grafts with various punch sizes. In a clinical trial, a total of 100 vitiligo patches in 50 patients with stable vitiligo were randomly allocated to motorized 0.5-mm micropunch grafting in epidermal and dermal orientations, respectively. The grafts were implanted at intervals of 5 mm at the recipient site. Treatment success was defined as greater than 75% repigmentation. In the animal study, all grafts were shown to be well integrated into the recipient site within 3 weeks. In the clinical trial, treatment success was achieved in 72% and 76% of the epidermal and dermal orientation groups, respectively; a cobblestone appearance was observed in 4% and 2%, respectively. In conclusion, we demonstrated that this new grafting method irrespective of epidermal-dermal orientation using motorized 0.5-mm micropunch grafting was effective and safe. We have named this the "skin seeding technique" and it differs from traditional punch grafting in that it can be performed regardless of the graft orientation.

RESUMEN

OBJECTIVE: Punch-grafting is a traditional technique to enhance wound healing, which has been associated with significant pain reduction. There are few studies measuring pain reduction after punch grafting, our study was designed to measure this outcome. METHOD: Patients with hard-to-heal wounds treated with punch grafting were included in a single centre prospective study. Wound pain intensity was measured using a Visual Analogue Scale (VAS) at baseline (before the procedure) and at three time points after the procedure. Punch grafting was performed in an outpatient setting. Patient demographic data, wound aetiology and percentage of graft take were recorded. RESULTS: A total of 136 patients were included (62 men and 74 women). Mean age was 60±35 years and 51 (38%) had venous leg ulcers (VLU), 29 (21%) had postoperative wounds, 15 (11%) Martorell ulcers, 15 (11%) traumatic wounds, four (3%) arterial ulcers and 22 (16%) 'other' ulcers. Of the patients, 38 (28%) did not present with painful ulcers and, after punch grafting, all of them remained painless; 29 (21%) patients obtained >70% pain reduction, whereas 73 (54%) patients achieved pain suppression. Pain suppression did not depend on the percentage of graft take. CONCLUSION: Punch-grafting is a simple, technique that not only promotes wound healing but also reduces pain. It can also be performed on an outpatient basis. Further studies should be performed to achieve a better understanding of this beneficial finding. Declaration of interest: The authors have no conflicts of interest to declare.

RESUMEN

BACKGROUND: Punch grafting for vitiligo is time-consuming and can result in cobblestone-like appearances. We devised a motorized 0.8-mm micropunch grafting procedure to overcome these limitations. OBJECTIVE: To assess the therapeutic effectiveness and adverse events associated with micropunch grafting in refractory vitiligo. METHODS: We retrospectively reviewed 230 cases in 208 patients with stable vitiligo who underwent motorized 0.8-mm micropunch grafting during January 2015-August 2017. Treatment success was defined as ≥75% repigmentation, and factors associated with the outcome were assessed. RESULTS: Overall, 181 of 230 lesions (78.7%) achieved treatment success after a median of 6 months with postoperative excimer therapy. Lesions on the face and neck, and disease stability of ≥12 months were good prognostic factors for treatment success. Common adverse events were color mismatch (24.8%) and cobblestone appearance (18.3%). Overall, the treatment was tolerable. LIMITATIONS: This was a retrospective study. CONCLUSION: Micropunch grafting using a motorized 0.8-mm punch can successfully treat refractory vitiligo with short procedure times and excellent outcomes. This technique could be a rapid and convenient surgical option with acceptable adverse events and is promising for treating refractory vitiligo on an outpatient basis, particularly in patients who are unlikely to tolerate prolonged surgery.

RESUMEN

OBJECTIVE: To compare the efficacy of follicular hair transplantation and mini punch graft in the treatment of stable vitiligo. METHODS: Thirty-two patients with stable vitiligo were included in this comparative study. A single patch from each patient was divided into two halves: one half was treated by punch graft, while the other half was treated by follicular hair transplantation followed by excimer light twice weekly, and the outcome was assessed at 0, 1, 3 and 6 months post operatively by photography and quartile scale. RESULTS: At the final visit, the percentage of improvement of vitiligo in punch graft-treated side was significantly higher than that in follicular hair transplantation-treated side (p < 0.05). Also, repigmentation after punch grafting occurred after a mean period of 2.5 ± 0.5 weeks (range, 2-3 weeks), while after follicular hair transplantation, repigmentation occurred after 5.2 ± 1.9 weeks (range, 5-8 weeks) (p < 0.05). Cobblestone appearance was the most common complication after punch graft; it occurred in 29 patients (90%), while no reported side effects occurred after follicular graft technique. CONCLUSION: Punch grafting is more effective than follicular grafting in the treatment of stable vitiligo; however, follicular hair transplantation is cosmetically better, so we recommend it in exposed areas as face.

RESUMEN

BACKGROUND: To date, autologous punch grafting appears to be the easiest and least expensive surgical technique for stable vitiligo and piebaldism. Punch grafting is available worldwide, with no need for specialised instruments. However, no reliable data on efficacy and safety of different punch depths and punch sizes are available. OBJECTIVE/METHODS: To compare the efficacy and safety of different punch depths and punch sizes in autologous punch grafting, a randomised controlled trial was performed in 33 patients with vitiligo or piebaldism. In each patient, four depigmented regions were allocated to: 1.5 mm deep grafts, 1.5 mm superficial grafts, 1.0 mm deep grafts, and 1.0 mm superficial grafts. Primary outcome was the total pigmented surface area. Secondary outcomes were Patients' Global Assessment (PGA) and side effects. RESULTS: Six months after grafting, 1.5 mm grafts showed a significantly larger pigmented surface area compared to 1.0-mm grafts (p < 0.001), though more side effects as well. No significant differences in the total pigmented surface between different punch depths were found. Deep grafts showed more erythema compared to superficial grafts. CONCLUSION: We recommend 1.5 mm superficial grafts in autologous punch grafting for trunk and proximal extremities in patients with stable vitiligo and piebaldism.

RESUMEN

BACKGROUND: A prominent role of hair follicle-derived cells in epidermal wound closure is now well established but clinical translation of basic research findings is scarce. Although skin punch grafts have been used as a therapeutic intervention to improve healing of chronic leg ulcers, they are normally harvested from nonhairy areas, thus not taking advantage of the reported role of the hair follicle as a wound-healing promoter. OBJECTIVE: We sought to substantiate the role of hair follicles in venous leg ulcer healing by transplanting hair follicle-containing versus nonhairy punch grafts. METHODS: This was a randomized controlled trial with intraindividual comparison of hair follicle scalp grafts and nonhairy skin grafts transplanted in parallel into 2 halves of the same ulcer. RESULTS: Ulcer healing measured as the average percentage reduction 18 weeks postintervention was significantly increased (P = .002) in the hair follicle group with a 75.15% (SD 23.03) ulcer area reduction compared with 33.07% (SD 46.17) in the control group (nonhairy grafts). LIMITATIONS: Sample size was small (n = 12). CONCLUSION: Autologous transplantation of terminal hair follicles by scalp punch grafts induces better healing than punch grafts harvested from nonhairy areas. Hair punch grafting is a minimally invasive surgical procedure that appears to be effective as a therapeutic tool for chronic venous leg ulcers.
