Incidence of host site complications in periocular full thickness skin grafts

Surgical Reconstruction in Malignant Eyelid Tumors

OBJECTIVE

To report the histopathological subtypes of malignant eyelid tumors treated surgically in the author's clinic and to present the author's graft and flap preferences in the reconstruction of the eyelid defect after surgical excision.

METHODS

This retrospective study included 33 patients who underwent malignant eyelid tumor excision, followed by eyelid reconstruction. A frozen section was performed during surgery to assess surgical margins in all patients. Demographic characteristics, histological classification, localization, and size of the tumor, postoperative defect size, follow-up period, complications, and recurrence rate were recorded.

RESULTS

Of the patients with a mean age of 66.6 ± 15.3 (range: 23-94), 15 (45.5%) were females and 18 (54.5%) were males. The lower eyelid was the most commonly involved site in 27 (81.8%) patients. Basal cell carcinoma was the most frequently diagnosed type of malignant cancer in 81.8% (n = 27) of the cases. Among the tumor subtypes, nodular type basal cell carcinoma was the most frequently observed subtype in 10 (30.3%) patients. Wide excision with different flap and graft techniques was performed in 26 (78.8%) patients with defect sizes of 40% or larger. In the author's study, the most preferred flap technique for anterior lamella reconstruction was the Tenzel semicircular flap (30.3% n = 10). The most frequently preferred flap for posterior lamella reconstruction was the Hughes tarsoconjunctival flap (30.3% n = 10). There were no flap or graft failures in any of the author's cases.

CONCLUSION

In the treatment of malignant eyelid tumors, different local flap and graft techniques selected according to the size of the defect have successful anatomical results in reconstructive surgery after frozen section controlled excision.

Reconstruction of Full-Thickness Eyelid Defects Following Tumor Resection: The Bucket Handle Modification

PURPOSE

To describe a modified approach for full-thickness lower eyelid defect reconstruction.

METHODS

This is a retrospective review of 5 patients with large full-thickness lower eyelid defects after tumor resection requiring reconstruction. For these lower eyelid defects, a lateral-based or superior-based tarsoconjunctival pedicle flap from the upper eyelid was used to rebuild the posterior lamella. In all cases, the anterior lamella was supplied from an adjacent myocutaneous flap in a bucket handle configuration. Data collection included tumor type and location, size of eyelid defect, presence of canalicular involvement, postoperative eyelid position, patient satisfaction, and complication rates.

RESULTS

Five eyelids of 5 patients underwent Mohs micrographic excision of basal cell carcinoma followed by reconstruction with a bucket handle flap. Age range was 68 to 96 years old (mean of 81 y). Five patients presented with lower eyelid involvement. The defect size ranged from 80% to 100% of the eyelid. Three patients had canalicular involvement and required bicanalicular nasolacrimal stent placement. After reconstruction, all patients showed good eyelid apposition to the globe with excellent esthetic outcome. No revision procedures were done. Average follow-up time was 13 months (range of 8 to 21 mo).

CONCLUSION

The bucket handle flap for full-thickness eyelid reconstruction is a simple technique that allows for preservation of all anatomical layers of the anterior lamella. This technique shows promising functional and esthetic outcomes.

Resolving trapdoor phenomenon without secondary procedure after forehead flap on medial canthal region

Herein, we present a case of basal cell carcinoma in a 59-yearold woman. It presented with painless itchy, black, gradually enlarged patches which were easily bled under her left eye since three years ago. A dermatological examination of the left medial canthus region obtained hyperpigmented plaques (2x0.8x0.1 cm) with uneven skin texture, irregular borders, and erosion on the center of the lesion. We performed forehead flap technique surgery followed by eight-month monitoring, resulting in a satisfying outcome in both function and appearance. The thinning technique and adjusting the flap size from the forehead area to the medial canthus should be as thin as possible to avoid differences in skin thickness and post-reconstruction hypertrophic scars. A bulging appears on the surgical site a month after the procedure, known as the trapdoor phenomenon, on the 8th month of followup, the trapdoor phenomenon disappeared.

Periorbital reconstructive techniques following Mohs micrographic surgery or excisions: a systematic review

There are many articles in the literature on periorbital reconstruction after Mohs micrographic surgery (MMS) or surgical excision, however, the literature lacks a comprehensive systematic review of these reports. We performed a systematic review of published data on periorbital defect reconstruction to identify trends in the literature. A comprehensive search of eight databases was performed. To be included in the study, articles had to be published in English between 2005 and 2020 and contain repair data for MMS or excision defects in the periorbital region. Studies with less than four patients, literature or systematic reviews, and abstract-only publications were excluded. Data extracted from eligible articles included the authors' medical specialties, study design, subject number and demographics, defect characteristics, procedure type, reconstructive methods, complications, outcome measures, and method of outcome assessment. 53 studies met the inclusion criteria. The first and last authors' specialties were ophthalmology (47%), plastic and reconstructive surgery (23%), dermatology (13%), otolaryngology (4%), or were multi-specialty collaborations (13%). Only 5 of the studies were prospective. Defects were located on the lower eyelid (55%), medial canthus (31%), upper eyelid (8%), lateral canthus (4%), or a combination of these sites (2%). Reconstructive methods were reported for 3678 cases and included linear repair (18%), advancement flap (8%), rotation flap (5%), transposition flap (3%), island pedicle flap (1%), unspecified local skin flap (21%), skin graft (23%), secondary intention (4%), tarsoconjunctival flap (3%), and combined reconstruction techniques (13%). Thirty-three of 53 articles specified the periorbital subunit for each reconstructive technique that was employed. Among these 33 articles which allowed for correlation between defect location and reconstructive technique, the most utilized repair method for lower eyelid defects was local skin flap. Defects on the upper eyelid or medial canthus were most frequently repaired with a skin graft. Forty articles commented on cosmetic outcomes, however, only 3 of these articles utilized a defined grading system, objective measurements, or independent reviewers to assess the cosmetic outcomes. The methods of reconstruction in this review were diverse, however, local skin flaps and grafts were the most utilized techniques. In future reports, increased reporting of reconstructive technique by defect location as well as increased use of standardized assessments of aesthetic outcomes can help strengthen this body of literature.

State of the Evidence for Facial Skin Cancer Reconstruction

This review provides a comprehensive presentation of the evidence available in facial reconstruction post-Mohs micrographic surgery. Given the large diversity in post-Mohs reconstruction, there are limited guidelines in the management of defects. The aim of the present work is to provide a review of the best evidence as it pertains to several considerations in facial reconstruction. Data suggests that Mohs micrographic surgery and many reconstructive procedures can be performed as outpatient procedures under local anesthesia, with narcotic pain medication only given in certain patient populations following a minority of reconstructive procedures. Perioperative and topical antibiotics are generally not indicated. Aspirin and warfarin can generally be continued for most reconstructive procedures, but clopidogrel and novel anticoagulants may predispose to increased bleeding complications. Delayed reconstruction appears to be safe, although data are discordant on this topic. No specific wound closure technique or suture choice appears to be consistently superior. Given the lack of robust comparative studies, consistent methodology, and variable defect sizes/locations, no robust evidence-based guidelines can be generated for reconstruction techniques of facial subsites.

Single-staged Tunneled Forehead Flap for Medial Canthal and Eyelid Reconstruction

Purpose:

The paramedian forehead flap, while initially used for reconstruction of nasal defects, has been adapted for repair of anatomical subunits in the medial canthal and eyelid area. A significant obstacle for utilizing the flap has been the bulky, unsightly vascular pedicle that is maintained between surgical stages. We describe our surgical experience using the tunneled variation in a single stage procedure.

Methods:

A retrospective chart review was performed of three surgeons’ charts over a 5-year period. All patients who underwent the tunneled paramedian forehead flap variation were selected. Outcomes measured included underlying pathology, Mohs defect area and depth, and canalicular involvement.

Results:

A total of 20 tunneled flaps were performed after successful Mohs excision of cutaneous malignancies. The average Mohs defect surface area was 13.57 cm² with depth down to periosteum (n = 13), bone (n = 5), or orbital fat (n = 2). Five patients had full-thickness eyelid defects (25%), and nine (45%) had canalicular defects. The overall complication rate for this study was low with no flap failure. Two patients (10%) desired thinning of the subcutaneous flap for improved cosmesis, and one patient (5%) required further eyelid revision due to the complexity of the initial Mohs defect. The remaining 17 patients required no further surgical procedures.

Conclusion:

The tunneled paramedian forehead flap is a useful technique for medial canthal and eyelid reconstruction. This technique allows reconstruction of a challenging area. Complication rates are low, and this tunneled variation provides a single stage variation to the traditional multistage forehead pedicle flap.

Management of full-thickness skin grafts

Full-thickness skin grafts are a commonly used reconstructive method following Mohs micrographic surgery. The literature varies on the most appropriate methods of suturing and securing grafts as well as best practices to dress the graft postoperatively. Our objective was to review various approaches to management of full-thickness skin grafts, including suturing the graft, securing the graft, and topical emollient use on the graft postoperatively. It was found that absorbable sutures, plain gut, provide preferable outcomes with full-thickness skin grafts. The tie-over bolster is the most-used method for securing skin grafts after placement, although several other methods have demonstrated efficacy, including the polyurethane foam, sandwich, and quilting suture methods. While various topical emollients are used in the immediate postoperative period, plain white petrolatum is the least likely to form allergic contact dermatitis.

Utility of the Glabellar Flap in the Reconstruction of Medial Canthal Tumors after Mohs Surgery

The goals of periorbital region reconstruction are to obtain both functional and esthetic results. Medial canthus is the second most common periorbital location for basal cell carcinoma. If left untreated, it is locally destructive but rarely metastasizes. Incompletely resected medial canthal tumors recur or penetrate along the lacrimal path and expand to wider lesions. A safety margin is necessary to ensure a complete lesion resection. Since it was introduced in 1941, Mohs surgery has been promoted as an efficient method of dealing with infiltrative periorbital skin tumors. It has been shown to have high rates of complete cancer removal during surgery, minimizing the amount of normal tissue loss and securing better functional and cosmetic outcomes. Due to its concave contour and convergence of skin units with variable thickness, texture and mobility, reconstruction of the medial canthal region (MCR) remains challenging. Reconstructive methods such as free full-thickness skin grafts and glabellar flaps have been used alone or in combination with other techniques. The concavity of the canthus must be achieved, but the maintenance of the normal contour and symmetry of the surrounding tissue is critical. The glabellar flap (GF) is a triangular advancement flap that adequately restores the volume in deeper defects, guaranteeing sufficient vascular support without complex or undesirable scars. We present two cases of basal cell carcinoma affecting the MCR that was successfully reconstructed using a GF alone in one case and together with a cheek advancement flap in the second one. In both cases, tumor excision was performed using Mohs surgery.

Evolution of ischemia and neovascularization in a murine model of full thickness human wound healing

Translation of wound healing research is limited by the lack of an appropriate animal model, due to the anatomic and wound healing differences in animals and humans. Here, we characterize healing of grafted, full-thickness human skin in an in vivo model of wound healing. Full-thickness human skin, obtained from reconstructive operations, was grafted onto the dorsal flank of NOD.Cg-KitW41J Tyr + Prkdcscid Il2rgtm1Wjl /ThomJ mice. The xenografts were harvested 1 to 12 weeks after grafting, and histologic analyses were completed for viability, neovascularization, and hypoxia. Visual inspection of the xenograft shows drying and sloughing of the epidermis starting at week four. By week 12, the xenograft appears healed but has lost 63.05 ± 0.24% of the initial graft size. There is histologic evidence of epidermolysis as early as 2 weeks, which progresses until week 4, when new epidermis appears from the wound edges. Epidermal regeneration is complete by week 12, although the epidermis appears hypertrophied. An initial increase of infiltrating immune mouse cells into the xenograft normalizes to baseline 6 months after grafting. Neovascularization, as evidenced by positive staining for the proteins human CD31 and alpha smooth muscle actin, is present as early as 2 weeks after grafting at the interface between the xenograft and the mouse tissue. CD31 and alpha smooth muscle actin staining increased throughout the xenograft over the 12 weeks, leading to greater viability of the tissue. Likewise, there is increased Hypoxia Inducible Factor 1-alpha expression at the interface of viable and nonviable tissue, which suggest a hypoxia-driven process causing early graft loss. These findings illustrate human skin wound healing in an ischemic environment, providing a timeline for use of full thickness human skin after grafting in a murine model to study mechanisms underlying human skin wound healing.

Ectropion in Dermatologic Surgery: Exploration and Reconstruction Techniques

Ectropion, or eyelid eversion, is the most common form of eyelid malposition. By impairing the eyelid's protective function, ectropion can cause epiphora, lagophthalmos, keratinization, chronic irritation, pain, and ulceration. There are 5 types of ectropion, each with a different cause: congenital, paralytic, involutional, cicatricial, and mechanical. The most common presentation in dermatology is involutional eversion with a mechanical or tractional element. Several options exist for the surgical repair of ectropion and choice of technique will depend on the main pathogenic component. We review the basic anatomy of the eyelid and describe examination techniques for assessing risk and preventing ectropion and for identifying the main pathogenic component in order to select the most suitable repair technique.

Rhombic Flap: A Useful Flap for Small-to-Medium Defects of the Medial Canthus

BACKGROUND

Medial canthal defects are frequently encountered yet present specific challenges for the reconstructive surgeon. Surgical repair in this area may inadvertently lead to canthal webbing, ectropion, and/or epiphora. The rhombic flap is a versatile workhorse in the reconstructive armamentarium for canthal defects.

OBJECTIVE

To describe the use of the inferiorly based rhombic flap for reconstructing defects on the medial canthus.

METHODS

A retrospective analysis of the Mohs micrographic surgery cases was performed. All cases in which an inferiorly based rhombic flap was used for canthal reconstruction between 2012 and 2017 were identified. Defect size, location, and any postoperative complications were noted. Surgical scars were scored using the Vancouver Scar Scale.

RESULTS

There were 34 cases (17 men and 17 women). Age ranged from 38 to 86 (mean 69). Defect size varied from 0.6 to 2.1 cm in diameter. Postoperative complications were uncommon and minor.

CONCLUSION

The rhombic flap is a versatile and useful option for reconstructing surgical defects of the medial canthus.

Efficacy of lateral eyelid-block excision with canthoplasty and full-thickness skin grafting in lower eyelid cicatricial ectropion

Purpose

To report on the outcomes of our preferred surgical technique for the correction of lower eyelid cicatricial ectropion

Methods

We conducted a retrospective, nonrandomized, interventional analysis of a consecutive case series of patients with cicatricial lower lid ectropion treated with adhesiolysis, lateral eyelid‐block excision with canthoplasty and full‐thickness skin grafting. Donor sites included the ipsi‐ or contralateral upper eyelid and pre‐ or retroauricular skin. All patients were treated by one of our oculoplastic surgeons in the period from January 2005 to January 2017 in the Rotterdam Eye Hospital/Focus Clinic Rotterdam. We assessed postoperative lower eyelid apposition, the occurrence of intra‐ and postoperative complications and the reoperation rate.

Results

We included 38 eyelids of 32 patients, of whom 17 were male and 15 were female. The minimal postoperative follow‐up was 3 months. A total of 27 of 38 eyelids showed good postoperative apposition. Skin graft donor sites were the ipsi‐ or contralateral upper eyelid (47% and 16%, respectively) and the pre‐ or retroauricular skin (26% and 11%, respectively). No intraoperative complications occurred, but one patient developed a transient allergic contact dermatitis in the early postoperative phase. Two of 38 eyelids (two of 32 patients) required another surgical intervention (block excision) for residual or recurrent ectropion, with favourable outcomes. There was 100% viability of the skin grafts.

Conclusion

Repair of lower eyelid ectropion with lateral block excision, canthoplasty and full‐thickness skin grafting is an effective procedure with minimal donor site morbidity, excellent graft survival rates and a low reoperation rate.

Laterally Based Orbicularis Oculi Myocutaneous Flap: Revisiting for the Secondary Ectropion Correction

BACKGROUND

The management of lower eyelid ectropion is considered a challenge. Lower eyelid ectropion is conventionally reconstructed with a full-thickness skin graft or a local flap. However, complications as scar contracture and the recurrence of ectropion frequently occur. This article describes an effective surgical technique for ectropion correction using an upper eyelid as the laterally based orbicularis oculi myocutaneous flap.

METHODS

The flap was used in 7 patients who were subjected to lower eyelid reconstruction. A strip of unipedicled orbicularis oculi myocutaneous flap from the lateral canthus was elevated and transposed to the lower eyelid to suspend the lower eyelid and repair the skin defect.

RESULTS

Satisfactory eyelid function and cosmetic appearance were obtained and no recurrence was found in 2-years follow-up. The method proved that the donor scar was well hidden in the supratarsal crease. Mild flap color change occurred in the early stages but disappeared gradually within 2 months after.

CONCLUSIONS

The use of this flap not only gives similar tissue reconstruction, additional support, well-hidden scar, and no loss of function, but also fast flap rising with the reliable donor. With a thorough knowledge of anatomy, the authors believe that their technique described below will expand anatomical understanding and powerful reasons for using laterally based orbicularis oculi myocutaneous flap for not only reconstructive but also aesthetic surgeons.

Deepening Fornix Technique Using Central Split-Medium Thickness Skin Graft to Treat Contracted Anophthalmic Sockets

PURPOSE

The aim of thhis study was to present the outcomes of postauricular split-medium thickness skin graft (SMTSG) to treat anophthalmic sockets with contracted fornices.

METHODS

This case series enrolled patients with grade 2 or 3 anophthalmic sockets between 2015 and 2016. Data were collected on patient demographics, objective and subjective parameters preoperatively and 180 days postoperatively. Success of the surgery was graded on the height of the graft, the depth of the superior and inferior fornices, and presence/abscence of lagophthalmos, entropion, and ability to retain an external prosthesis.

RESULTS

Eighteen patients were enrolled with a mean age of 35.9 ± 18 years. The median height of the graft was 22 mm (25% quartile = 18.75) when removed and 20 mm (25% quartile = 16) postoperatively. The median depth of the superior fornix was 6.5 mm (25% quartile = 4.5 mm) preoperatively and 10 mm (25% quartile = 8 mm) postoperatively (P = 0.5). The median inferior fornix depth was 7 mm (25% quartile = 3.5 mm) preoperatively and 8 mm (25% quartile = 5 mm) (P = 0.27) postoperatively. Preoperatively, there were 13 (72.2%) patients with lagophthalmos, 10 (44.4%) with entropion, 3 (37.5%) with poor prosthesis retention, and 5 (62.5%) who were unable to retain the prosthesis. Postoperatively, 7 (38.9%) patients had lagophthamos, 1 (5.6%) had entropion, and all the patients could retain the prosthesis. None of the sockets had a foul odor postoperatively.

CONCLUSIONS

Postauricular SMTSG achieves successful outcomes for the treatment of contracted anophthalmic sockets, reshaping the anterior socket surface and deepening the fornices.

Changing the Paradigm in Medial Canthal Reconstruction: The Bridge Principle and the Croissant-Like Keystone Island Perforator Flap as An Alternative for Medium Size Soft Tissue Defects in Internal Canthus Reconstruction

INTRODUCTION

Medial canthus is a common area of skin cancer prevalence. Defects in this region represent a challenging reconstructive task. The nasal version of keystone perforator island flap (KPIF) has proven its versatility. The aim of the present study was to expand its utilization in the neighbor medial canthus area. A modified croissant-like KPIF (CKPIF) was used resolving inner convexity-related problems. The presence of procerus in the glabella area, bridging a surface from nasalis up to the frontalis, changed the traditional dissecting flap technique. Thus, the authors introduce the bridge principle, which consists of the indirect transfer of the flap to the defect site through a muscular "bridge" (the procerus). The authors report their experience in medial canthal reconstruction combining a modified KPIF with a new dissecting "principle."

METHODS

From November 2016 to July 2017, a series of patients presenting soft tissue defects of various dimensions in the medial canthus, secondary to tumor extirpation, sustained reconstruction with a CKPIF dissected with the bridge principle.

RESULTS

A total of 15 patients were treated with this new technique. Their mean age was 75.3 years. The mean size of the defect was 2.08 cm (length) × 1.5 cm (width). All flaps survived without any sign of venous congestion. A transient epiphora presented in 4 patients (4/15 or 26.6%), which was subsided 2 months later.

CONCLUSION

A new approach following a novel paradigm was introduced to resolve an old problem. Initial outcomes are encouraging. However, longer series are needed to extract definitive and safer conclusion.

Use of a perforator/subcutaneous pedicled propeller flap for reconstruction of lower eyelid defects

Full-thickness skin grafts (FTSGs) and flaps from the upper eyelid or cheek can be used for reconstruction of lower eyelid defects, including the anterior lamella. However, the upper eyelid has a limited and insufficient amount of skin, whereas cheek flaps have a restricted arch of rotation. Here we report the procedure and outcomes of a perforator/subcutaneous pedicled propeller flap for reconstruction of lower eyelid defects including the anterior lamella. A retrospective study of 12 patients who underwent treatment for eyelid anterior lamella defects with perforator/subcutaneous pedicled propeller flaps was conducted between March 2015 and June 2017. The propeller flap was planned to rotate around the perforator (as the pivot point), which was detected with a hand-held Doppler in the vicinity of the defect. The flaps were perforator pedicled for 10 patients and subcutaneous pedicled for the other two patients. The flap was rotated around the pedicle and placed on each patient's defect without tension. No vascular compromise occurred with any of the flaps. The most important complications were post-operative oedema and ecchymosis. Inferior eyelid defects including the anterior lamella could be reconstructed by using propeller flaps from the adjacent tissue. The main advantages of this flap included easy access to the defect, no impairment in eyelid function and very good aesthetic results.

Functional and aesthetic outcomes of eyelid skin grafting in facial nerve palsy

AIM

To report the functional and aesthetic outcomes of eyelid full-thickness skin grafting (FTSG) in patients with facial nerve palsy (FNP).

METHODS

This is a retrospective, non-comparative, single-centre review of all patients with FNP who underwent FTSG over an 8-year period. Functional outcomes were collected through case notes review: CADS (cornea, static asymmetry and dynamic and synkinesis) score facial nerve grading and lagophthalmos on blink, gentle and forced closure. Marginal reflex distance (MRD1 and MRD2) was calculated on standardised photographs. The aesthetic outcomes were assessed objectively by two blinded independent assessors who assessed standardised photographs based on a mutually agreed grading scale. Both functional and aesthetic outcomes were measured preoperatively, and at early (1-3 months), intermediate (3-6 months) and late (>9 months) postoperative periods.

RESULTS

A total of 28 eyelid FTSGs were performed on 21 patients (11 female, 10 male) between 2008 and 2016. The mean age was 68 (range, 16-89) years and the mean follow-up was 20.8 (range, 12-30) months. The CADS score (cornea (p<0.001), static asymmetry (p<0.001), dynamic function (p<0.001)), MRD2 (p=0.002) and lagophthalmos (blink (p=0.003), gentle (p<0.001), forced (p=0.003)) improved through early and late postoperative periods. Aesthetically, the grafts appeared to look natural in terms of colour, surface contour and graft edge from the intermediate postoperative period and continued to improve significantly by the late postoperative period.

CONCLUSION

The use of periocular FTSG is effective in improving lagophthalmos and periorbital symmetry in patients with FNP where skin contraction exists. They should be considered as an adjunct to other oculoplastic procedures for both functional and aesthetic rehabilitation.

Tie-Over Bolster Dressings vs Basting Sutures for the Closure of Full-Thickness Skin Grafts: A Review of the Literature

BACKGROUND

Full-thickness skin grafting is a well-established technique in the reconstruction of various tissue defects and wounds. However, lack of uniformity in the procedure of closing and securing the grafts has led to a wide range of different techniques.

OBJECTIVE

This article reviews the use of tie-over bolster dressings compared to basting sutures for the fixation and postsurgical immobilization of full-thickness skin grafts (FTSGs), discusses details of each method, and proposes a practice guideline for the closure of FTSGs.

METHODS

A traditional review of the literature was performed through a search of PubMed using the following keywords: full-thickness skin graft, FTSG, closure, suture, tie-over bolster, quilting, and bolster.

RESULTS

The current literature regarding tie-over bolster dressings does not demonstrate improved outcomes compared to quilting sutures. The 2 techniques appear equivalent in terms of utility and outcome, both possessing distinct advantages and disadvantages.

CONCLUSION

Despite minimal head-to-head studies between tie-over bolsters and quilting, the best evidence from the literature appears to show comparable results regarding graft take, cosmetic outcomes, and postoperative complications. Ultimately, the choice of using a tie-over bolster technique or quilting sutures relies on surgeon preference and anatomic location.

Excision of nodular basal cell carcinoma involving the lower eyelid tarsal skin using a grey line-splitting, posterior lamella-sparing technique

Purpose: To describe a posterior lamella-sparing technique to resect nodular basal cell carcinoma involving the inferior part of the tarsal skin of the lower eyelid. Surgical Technique: Excision of nodular basal cell carcinoma of the tarsal skin using a grey-line-splitting technique with preservation of the posterior lamella. Specimen was sent for frozen section control. Additional excision was performed in caseof irradicality. The defect was closed with a free skin graft from the ipsi- or contralateral upper eyelid. Results: We show a case series of three patients with lower eyelid basal cell carcinoma and investigated radicality on histology, aesthetic outcome and clinical recurrence during a follow-up of 18 months. Pre, intra, and postoperative photographs were obtained. In all cases radicality was reached. In all patients, the skin graft was viable, with no recurrence after 18 months. Excellent aesthetic results were obtained. Conclusion: Anterior lamellar resection of nodular basal cell carcinomas involving the tarsal lower eyelid skin using a grey line lid-splitting technique is a simple and one-step technique with good clinical outcome. It may avoid the morbidity associated with full thickness eyelid resection and might be useful for other, nonmalignant eyelid lesions.

Bioengineered dermal substitutes for the management of traumatic periocular tissue loss

PURPOSE

Traumatic periocular injuries occasionally result in significant soft tissue loss, for which there are limited management options that provide satisfactory cosmetic and functional outcomes. The authors describe the use of a bioengineered dermal substitute (Integra® Dermal Regeneration Template [DRT], Integra LifeSciences, Plainsboro, NJ) as an alternative to immediate flap reconstruction or skin grafting.

METHODS

Retrospective interventional case series of patients who underwent DRT placement for periocular tissue loss at the time of trauma. In each case, primary closure or immediate flap reconstruction was deemed impractical or undesirable due to the size and location of the primary and associated secondary defects. One to four weeks later, the outer silicone layer was removed and healing assessed. Additional reconstructive techniques were performed as needed.

RESULTS

Three patients were treated at Bascom Palmer Eye Institute and one at Byers Eye Institute at Stanford. The defects healed completely in two patients, and by 79.2% in a third, with no need for additional reconstructive surgery. In the remaining patient, the defect was significantly downsized by 56.1%, allowing for a simpler flap reconstruction.

CONCLUSIONS

Bioengineered dermal substitutes should be considered as a viable alternative to traditional reconstructive techniques for large periocular defects resulting from trauma. The outer silicone layer prevents desiccation and serves as a protective barrier, while the inner collagen matrix organizes the growth of neo-dermis and minimizes wound contraction. The dimensions of cutaneous defects can therefore be reduced dramatically, potentially eliminating the need for skin grafting and/or reducing the ultimate complexity of flap reconstruction.

Ocular Adnexal Reconstruction for Cutaneous Periocular Malignancies

Although the majority of lesions present in the periocular region are benign, periocular cutaneous malignancies are certainly not uncommon and must be considered. The management of nonmelanoma cutaneous malignancies is predominately surgical with Mohs micrographic surgery or excision with frozen sections. The approach to reconstruction of the resulting defects depends on the defect location and size. When able, it is preferable to close lesions directly or with the recruitment of adjacent tissue in an effort to preserve the inherent anatomy. The eyelid's dynamic function is thus maintained, which is essential for optimal ocular surface protection. However, larger and more extensive defects will require complex reconstructions that are able to restore the necessary structural integrity to the eyelids. The authors review the various reconstruction approaches for defects of all sizes involving the periocular area including nonmarginal defects and defects of the lower and upper eyelids, as well as those of the medial canthal region.

Eyelid Reconstruction with Full Thickness Skin Grafts After Carcinoma Excision

BACKGROUND

Various techniques have been proposed for reconstruction of the eyelid anterior lamella after carcinoma excision: among these are the transposition of skin flaps, and full-thickness skin grafts or combination of these two.

AIM

To present our experience in eyelid reconstruction with full-thickness skin grafts and to assess the aesthetic and functional outcomes.

PATIENTS AND METHODS

The present retrospective study included 39 patients (20 males, 19 females, mean age 71 yrs) with surgically excised eyelid carcinoma, followed by reconstruction using full-thickness skin grafts. The patients were treated between 2005 and 2014. Parameters recorded were patient demographics, histological classification of malignancy, tumor localization and size, postoperative defect size. In cases of large full-thickness lower lid defect Hughes tarsoconjunctival flap was used for reconstruction of posterior lamella. Full-thickness skin grafts donor sites included upper eyelid, preauricular area and inner brachial area. We appraised the grafts viability one week after surgery and the aesthetic results - 6 months after surgery by the graft colour and lid position.

RESULTS

In 95% of the cases the skin grafts were viable. The full-thickness skin graft (FTSG) failed in two patients because of subcutaneous haematoma. There were a few early postoperative complications including graft hypertrophy, graft contraction, and partial graft failure, which were managed without additional surgery. All 39 patients had normal postoperative lid function. All 39 had either good (14) or excellent (25) cosmetic results.

CONCLUSIONS

Our findings suggest that full-thickness skin graft is a good choice in periocular reconstructive surgery after carcinoma excision. The surgical technique is easy to perform producing proper functional and aesthetic results.

The optimal reconstruction size of nipple-areola complex following breast implant in breast cancer patients

Background

Changes in the areola size after reconstruction of the nipple-areola complex (NAC) following mastectomy and breast reconstruction with a silicon implant in primary breast cancer patients have not been well examined. This study aimed to investigate time-dependent changes in the size of the donor and graft NACs and to assess clinical factors influencing these changes.

Methods

Fifty-eight consecutive patients who underwent nipple-areola reconstruction were retrospectively evaluated. Nipple-areola diameter was measured immediately after the NAC reconstruction and at each follow-up visit for at least 36 months.

Results

The donor NAC constituted 81 % of the graft NAC at the time of operation. The size of the donor NAC gradually increased by up to 36.8 % after the operation. The size of the graft NAC showed a decrease by 4.5 % at 7 months, followed by recovery to the initial value. The ratio of the donor site size to the graft site size was increased at month 1 and then showed a gradual decrease to 1.08 at 36 months. A history of mastopexy or reduction for the donor site was independent factors associated with changes in the NAC size.

Conclusions

To achieve symmetry, the diameter of the donor NAC immediately after the reconstruction should be at least 20 % smaller than that of the graft NAC, especially for patients without a history of additional operations.

Full thickness skin grafts in periocular reconstructions: long-term outcomes

PURPOSE

To evaluate the outcomes of eyelid reconstruction in patients who underwent full thickness skin grafts.

METHODS

A retrospective, noncomparative intervention study of patients who underwent periocular reconstruction with full thickness skin grafts between 2005 and 2011.

RESULTS

One hundred consecutive Caucasian patients were included in the study, 54 women and 46 men. Mean follow up was 32 months. Indications for full thickness skin grafts were excision of eyelid tumors (98%) and cicatricial ectropion (2%). Site of lid defects were lower lid (60%), medial canthus (32%), upper lid (6%), and lateral canthus (2%). The skin graft donor sites were supraclavicular (44%), upper eyelid (24%), inner brachial (18%), and postauricular (14%).Early postoperative complications included lower eyelid graft contracture (1%) and partial failure (1%). Late sequelae included lower eyelid graft contracture (4%) and hypertrophic scarring (23%). Of the 23 patients with hypertrophic scar, 21 achieved good outcomes following massage with silicone gel and steroid ointment and 2 had persistent moderate lumpiness. No statistically significant association was found between graft hypertrophy and donor site or graft size. As high as 95% of all patients achieved good final eyelid position. Good color match was seen in 94% and graft hypopigmentation in 6%. An association between hypopigmentation and supraclavicular and inner brachial donor site was found to be statistically significant.

CONCLUSIONS

Most patients (94%) achieved good eyelid position and color match. Majority (91%) of the early postoperative cicatricial sequelae can be reversed by massage, steroid ointment, and silicone gel application. Full thickness skin grafts have excellent graft survival rates and have minimal donor site morbidity.

Skin graft survival on subcutaneous hinge flaps: an algorithm for nasal reconstruction

OBJECTIVES/HYPOTHESIS

To assess the survival of full-thickness skin grafts and perichondrial cutaneous grafts when placed on subcutaneous soft tissue flaps used in nasal reconstruction.

STUDY DESIGN

Retrospective case series from a secondary-care cutaneous cancer practice.

METHODS

Twenty-eight patients with nasal defects secondary to basal cell carcinoma excision were included. Clinical information, including case notes and photography, was obtained and analyzed. Graft survival was assessed in relation to type of graft and subcutaneous soft tissue flap employed for the reconstruction.

RESULTS

Overall graft survival was 79%, with 89% and 74% for perichondrial cutaneous graft and full-thickness skin grafts, respectively. Anecdotally, procerus and nasalis flaps were found to yield higher graft survival than cheek fat flaps.

CONCLUSIONS

The combination of subcutaneous soft tissue flap and skin graft cover offers a valuable addition to the treatment algorithm for nasal reconstruction following cutaneous malignancy excision.

Mohs micrographic surgery of the eyelid: an overview of anatomy, pathophysiology, and reconstruction options

BACKGROUND

Mohs micrographic surgery (MMS) is the ideal treatment for skin cancer removal. The advantages of MMS in the eyelid area include its high cure rate, tissue-sparing effects, and overall cost effectiveness.

OBJECTIVE

To review eyelid anatomy, detail ocular tumors that are amenable to MMS, and examine the surgical repair options commonly used in this area.

MATERIALS AND METHODS

A review of the literature on MMS of the eyelid was performed with specific reference to ocular anatomy, eyelid malignancy types, and surgical reconstruction.

CONCLUSION

Eyelid function is critical for the maintenance of ocular health and vision. MMS is an ideal skin cancer treatment for the delicate structure of the eyelid, where maximal tissue preservation is critical. There are a plethora of reconstruction options to consider after MMS has been performed in this area. The choice of repair and surgical outcome depend, in part, on the surgeon's knowledge of eyelid anatomy and his or her ability to assess the repair requirements of the post-MMS defect. Dermatologic surgeons can effectively work with other specialists to help ensure that their patients receive a cure with restored ocular function and optimal cosmesis.

Internal cantholysis for repair of moderate and large full-thickness eyelid defects

PURPOSE

To determine the safety and efficacy of internal cantholysis for closure of larger full-thickness eyelid defects.

DESIGN

Retrospective review of a consecutive case series.

PARTICIPANTS

Eighteen patients (18 eyelids) underwent internal cantholysis for repair of a moderate or large full-thickness eyelid defect during the study period.

METHODS

Retrospective review of a consecutive case series of all patients undergoing transconjunctival lateral cantholysis for repair of moderate and large full-thickness eyelid defects between October 2008 and November 2010. Moderate was defined as ≥ 14 mm in horizontal length, and large was defined as ≥ 20 mm in horizontal length.

MAIN OUTCOME MEASURES

Charts were reviewed for patient demographics; indication for surgery; defect size, type, and location; other concomitant repair; follow-up interval; and complications.

RESULTS

Eighteen patients (18 eyelids) underwent internal cantholysis for repair of a moderate or large full-thickness eyelid defect during the study period. Average patient age was 73 years (range, 45-94 years), and there were 10 male and 8 female patients. Average defect size was 19.0 mm (range, 14-25 mm). Average follow-up interval was 4.6 months (range, 1-12 months). Complications included eyelid margin notch (3 cases), persistent canthal dystopia (3 cases), trichiasis (2 cases), pyogenic granuloma (2 cases), eyelid margin nodule (1 case), lower eyelid elevation of 1 mm (1 case), and mild resolving medial lagophthalmos (1 case). No patient requested or required further surgery on the operated eyelid for any reason during the study period.

CONCLUSIONS

Internal cantholysis allows for closure of moderate and large full-thickness eyelid defects. Complications are acceptable in light of the morbidity of other therapeutic options, such as semicircular flap or shared eyelid flap procedures.

Island pedicle flaps for medial canthus repair

BACKGROUND

The medial canthus is a frequent site for skin cancer and reconstruction after Mohs surgery can prove to be challenging. In the literature various reconstruction methods are recommended for these cases. Flap reconstructions are mostly transposition flaps from the glabella, skin with different properties from that in the canthal region, hence mostly requiring correction in a second stage.

OBJECTIVES

To ascertain the utility of a different reconstruction method, applying island pedicle flaps for medial canthal lesions and obviating the necessity for second-stage corrections.

METHODS

A review was undertaken of the medical records and photographs of patients who had a pedicle island flap reconstruction for medial canthal defects after Mohs surgery. There were four different possibilities: a pedicle island flap from the cheek, the back of the nose or the glabella or a combination of these flaps.

RESULTS

Sixteen patients were reconstructed by pedicle island flaps for defects of the medial canthal area. A follow-up for all patients after 1 year indicated that all patients showed good to excellent results. No cases of web deformation and ectropion were found.

CONCLUSIONS

This flap is not mentioned in textbooks in reference to the reconstruction of canthal lesions and its value for this particular location is probably underestimated.

Viability of full-thickness skin grafts used for correction of cicatricial ectropion of lower eyelid in previously irradiated field in the periocular region

BACKGROUND

The purpose of this study was to evaluate the viability of skin grafts used for correction of cicatricial ectropion resulting from previous ablative surgery and radiotherapy for head and neck cancer and to report overall outcomes of cicatricial ectropion repair.

METHODS

This is a retrospective, noncomparative case series of all consecutive patients with head and neck cancer who had been exposed to high-dose radiation therapy in their periocular region and had surgical correction of their lower eyelid cicatricial ectropion through placement of a full-thickness skin graft and a lower eyelid tightening procedure by the same surgeon. The primary outcome measure was skin graft viability. Secondary outcome measures comprised postoperative complications, the overall outcome of ectropion repair as judged by improvement in symptoms of exposure keratopathy, and dependence on lubricating eye drops and ointments, as well as cosmetic improvement measured through a grading scale based on the degree of inferior scleral show and/or tarsal conjunctival eversion.

RESULTS

Twenty-five patients were eligible for the study. Nineteen men and 6 women had a median age of 63 years (range, 20-84 years). All 25 patients had high-dose radiation therapy for their head and neck cancer. All but 1 patient had major cancer ablative surgery performed before radiation therapy. Thirteen of 25 patients also received chemotherapy. There was 100% viability of the skin grafts used for the repair of lower eyelid cicatricial ectropion. There were a few postoperative complications including the need for revision surgery to correct residual ectropion in the lower eyelid in 2 patients, and a third patient required a revision surgery due to upper eyelid retraction and lagophthalmos after harvest of skin graft from the upper eyelid. Improvement was noted in the subjective symptoms in 22 of 25 patients (88%), whereas 17 patients (68%) were noted to have improvement in their clinical findings on slit lamp examination. All 20 patients, for whom good quality photos were available, had improvement in the degree of cicatricial lower eyelid ectropion as measured by the amount of inferior scleral show and tarsal conjunctival eversion, although 11 patients had some residual ectropion. All 20 had either good or excellent results in the appearance of their skin grafts.

CONCLUSION

Our findings suggest that full-thickness skin grafts are a nice option for correction of cicatricial lower eyelid ectropion in a previously radiated field; 100% of the grafts survived. The majority of patients had improvement of ocular surface damage and symptoms, with a decreased dependence on topical lubricants. All evaluable patients had improvement in the degree of cicatricial lower eyelid ectropion, although close to one-half of patients had some mild residual ectropion. The majority of patients had excellent appearance of the skin graft.

Prospective evaluation of dermatologic surgery complications including patients on multiple antiplatelet and anticoagulant medications

BACKGROUND

Few prospective studies have evaluated the safety of dermatologic surgery.

OBJECTIVE

We sought to determine rates of bleeding, infection, flap and graft necrosis, and dehiscence in outpatient dermatologic surgery, and to examine their relationship to type of repair, anatomic location of repair, antibiotic use, antiplatelet use, or anticoagulant use.

METHODS

Patients presenting to University of Massachusetts Medical School Dermatology Clinic for surgery during a 15-month period were prospectively entered. Medications, procedures, and complications were recorded.

RESULTS

Of the 1911 patients, 38% were on one anticoagulant or antiplatelet medication, and 8.0% were on two or more. Risk of hemorrhage was 0.89%. Complex repair (odds ratio [OR] = 5.80), graft repair (OR = 7.58), flap repair (OR = 11.93), and partial repair (OR = 43.13) were more likely to result in bleeding than intermediate repair. Patients on both clopidogrel and warfarin were 40 times more likely to have bleeding complications than all others (P = .03). Risk of infection was 1.3%, but was greater than 3% on the genitalia, scalp, back, and leg. Partial flap necrosis occurred in 1.7% of flaps, and partial graft necrosis occurred in 8.6% of grafts. Partial graft necrosis occurred in 20% of grafts on the scalp and 10% of grafts on the nose. All complications resolved without sequelae.

LIMITATIONS

The study was limited to one academic dermatology practice.

CONCLUSION

The rate of complications in dermatologic surgery is low, even when multiple oral anticoagulant and antiplatelet medications are continued, and prophylactic antibiotics are not used. Closure type and use of warfarin or clopidogrel increase bleeding risk. However, these medications should be continued to avoid adverse thrombotic events.

An evidence-based approach to the treatment of nonmelanoma facial skin malignancies

The Maintenance of Certification module series is designed to help the clinician structure his or her study in specific areas appropriate to his or her clinical practice. This article is prepared to accompany practice-based assessment of preoperative assessment, anesthesia, surgical treatment plan, perioperative management, and outcomes. In this format, the clinician is invited to compare his or her methods of patient assessment and treatment, outcomes, and complications, with authoritative, information-based references. This information base is then used for self-assessment and benchmarking in parts II and IV of the Maintenance of Certification process of the American Board of Plastic Surgery. This article is not intended to be an exhaustive treatise on the subject. Rather, it is designed to serve as a reference point for further in-depth study by review of the reference articles presented.

Use of local sliding flaps to manage deep localized burns of the hand

The incidence of hand burns in children is high. In the overall cases of body burns, hand and wrist burns account for about 39%. They may constitute a part of a larger burn of the body, or an isolated injury of the hand and wrist. The choice between early and late escharectomy and skin covering is still a matter of debate. Two cases of deep burns of the hands are presented in this report. The report shows a new way to close the residual wounds of deep burns.

Internal cantholysis for full thickness eyelid defects

Eyelid reconstruction requires an understanding of normal eyelid anatomy and function. A thorough understanding of the basic anatomy, contour, and mobility of the eyelids is essential in restoring the tissue to its presurgical level. There are many different surgical options to assist in the repair of full thickness eyelid defects involving the margin. Direct wound closure depends on eyelid laxity and is often possible with smaller defects. Moderate to larger sized defects are often under undue wound tension if direct closure is attempted. We have developed a new technique for closure of eyelid defects using a transconjunctival cantholysis to release the lateral canthal tendon cruces, thereby avoiding the external incision while still allowing for eyelid mobility. Using this technique for defects 15 mm in horizontal eyelid margin length or greater, we have found positive results. Direct closure of eyelid defects represents the most straightforward technique to repair any full-thickness eyelid defect and provides maximal functional and cosmetic results. Internal cantholysis represents an excellent option for repairing smaller and even larger full thickness eyelid defects. Eyelid mobility increases by 4-10 mm, sometimes more, and allows for closure of defects larger than even 20 mm.

Complications of Cicatricial Ectropion Repair with Pre-Auricular Wolfe Graft

An 85-year-old lady presented with a severe cicatricial ectropion several months after a fall. The abnormality was corrected with a procedure that involved the use of a retroauricular skin graft. This provided resolution of her ocular symptoms. Several months later, she had noted significant hair growth on the graft, but elected for this to be managed conservatively. Careful harvesting of the graft from the non-hairy area between the ear and the hairline is essential to prevent unwanted transplantation of terminal hairs. Surgical success is also dependent on the final aesthetic outcome.

Full-thickness skin grafts and perichondrial cutaneous grafts following surgical removal of cutaneous neoplasms of the head and neck

The objective of the study is to determine efficacy in terms of survival rate and cosmesis of "normal" full-thickness skin grafts (FTSGs) as compared to perichondrial cutaneous grafts (PCCGs) in facial reconstruction. A chart review of all facial reconstructions using FTSGs and PCCGs between 1995 and 2005 was undertaken. All patients were treated by the same surgeon. A total of 121 skin grafts were included in this study (70 FTSGs and 51 PCCGs). All patients were examined at days 5 and 10 to assess the viability of the graft. For esthetic evaluation, 70 photographs were available with a minimum follow-up of 6 months (42 FTSGs/59% of total; 28 PCCGs/54% of total). The photos were randomly shown to three raters, who had no previous knowledge about the graft being a FTSG or PGCG. The complete take rate of the FTSGs and of the PCCGs was respectively, 87% (9 failures) and 94% (3 failures) .This is no statistically significant difference (P = 0.1857). The cosmetic outcome of PCCGs overall scored better by the three raters. However, the esthetic rating between PCCG and FTSG was of no statistical significant difference (P = 0.06). In conclusion, both FTSGs and PCCGS are viable options in facial reconstruction, with no statistical difference in survival and cosmesis. They are simple and one-stage procedures. The PCCG is a smooth graft, containing a few sebaceous glands and possibly has less contraction.

Hemi-orbicularis oculi switch flap for upper eyelid defects

BACKGROUND

The technique chosen to reconstruct anterior lamellar defects of the upper eyelid requires careful consideration. We modified pre-existing techniques used to reconstruct anterior lamellar defects after tumour resection and have called this procedure a hemi-orbicularis oculi switch flap.

METHODS

This musculocutaneous flap is elevated with underlying orbicularis and its base abuts the anterior lamellar defect. The flap, which is half the height of the defect, is elevated and inset to cover the defect. Then, taking into consideration the extensibility of upper eyelid skin, the remainder of the defect and the donor site are closed directly.

RESULTS

Five patients with basal cell carcinoma, haemangioma, and xanthoma of the upper eyelid were treated by this method. All flaps survived and complications were minimal. Aesthetically and functionally good results were obtained by this method.

CONCLUSIONS

We have developed a surgical method for the reconstruction of anterior lamellar defects of the upper eyelid. The proposed method is technically simple and safe and provides consistent results for a potentially wide variety of upper eyelid tumours.

The Australian Mohs database: short-term recipient-site complications in full-thickness skin grafts

BACKGROUND

There are only a few reports on the outcome with full-thickness skin grafts (FTSG) in defect reconstruction after Mohs micrographic surgery (MMS).

OBJECTIVES

The objective was to evaluate the complications with FTSG in patients treated with MMS for cutaneous tumors.

METHODS

This study is based on a prospective data collection of all patients in Australia treated with MMS and monitored by the Skin and Cancer Foundation, between 1993 and 2002. Primary outcome measures were FTSG recipient-site complications (partial/complete graft failure, graft infection, acute bleeding/hematoma, graft hypertrophy, and graft contracture).

RESULTS

The study group included 2,673 patients (50.2% men) with a mean age of 64+/-14 years. Most tumors were basal call carcinoma (90.9%) and were located on the nose (63.8%), periocular area (14.8%), or auricular area (8.1%). A total of 11.7% of cases had recipient-site complications (graft hypertrophy, 42.3%; partial graft failure, 27.2%; graft contraction, 15.3%). Only 45.2% of complicated cases required treatment.

CONCLUSION

Short-term recipient-site complications occurred in less than 12% of reconstructions with FTSG. Graft hypertrophy and partial graft failure accounted for most cases of complications. The authors have indicated no significant interest with commercial supporters.

Medial Canthal Reconstruction by a Modified Glabellar Flap

AIMS

To present a modified technique for the preparation of glabellar skin flaps to reconstruct medial canthal defects.

METHODS

Ten consecutively treated patients were included who had skin defects after resection of skin tumours like basal cell carcinomas in the medial canthal area of a medium vertical diameter of 2.5 cm. The defects were closed by preparation of a modified glabellar flap. The pedicle of the flap was guided through a skin tunnel prepared diagonally at the root of the nose. The pedicle was resected 4 weeks after the initial surgery.

RESULTS

In all 10 cases, the procedure was adequate for reconstruction of the defect. There were no flap necroses and the cosmetic results were favourable in all cases. The resection of the pedicle could be performed easily in an out-patient procedure 4 weeks after the operation.

CONCLUSION

Glabellar flaps are established procedures to reconstruct medium to large defects of the medial canthus. Skin distortion in the area of the flap pedicle leading to a skin bulge and visible scars at the root of the nose and medial transposition of the eye brows can be reduced by a modification of the surgical technique preparing a skin tunnel for the flap pedicle. In our hands, the cosmetic results are better with the modified technique in comparison to the original procedure.

Erbium:YAG laser-assisted preparation of a combined dermal/full thickness sandwich skin graft

BACKGROUND

Skin grafting is a common procedure to close defects after tumor resection. However, delicate areas such as the heel or the sole of the foot can be closed with a specially designed graft as described in this article.

OBJECTIVE

To describe a surgical technique by means of erbium:YAG laser-assisted preparation of a combined dermal/full-thickness sandwich skin graft that facilitates the closure of defects, especially at mechanically stressed anatomic sites.

METHODS

Tumor defects on the sole of the foot of 28 patients were closed with a new dermal/full-thickness sandwich skin graft. To obtain this special graft, half of a full-thickness skin graft twice the size of the wound defect was deepithelialized with an erbium:YAG laser. After complete defatting of the transplant, the deepithelialized part was folded beneath the full-thickness part (upside down) resulting in a sandwich graft, enabling contact of the papillary dermis with the wound surface. Graft results were graded as excellent when more than 75%, good if 50-75%, fair if 25-50%, and poor if less than 25% of the transplant healed.

RESULTS

Results were graded as excellent in 32%, good in 54%, fair in 11%, and poor in 3% of the patients. Total graft loss was experienced in 1 of 28 patients. Complications such as bulky margins or infection were encountered in 14% of the patients.

CONCLUSION

The laser-assisted preparation of the combined dermal/full-thickness sandwich skin graft is a new technique that facilitates the closure of defects in delicate anatomic locations with high mechanical stress like the plantar sole.
