Long-term follow-up of donor site morbidity after defect coverage with Integra following radial forearm flap elevation

Use of the radial forearm free flap in eyelid and orbit defect reconstruction: A systematic review and meta-analysis

BACKGROUND

The radial forearm free flap (RFFF) is widely used in head and neck reconstruction and serves as a versatile option for complex soft tissue eyelid and orbital socket reconstruction, particularly following orbital exenteration. This study evaluated the success and complication rates of RFFF in these contexts.

METHODS

A literature search of the PubMed, Dynamed, DARE, EMBASE, Cochrane and British Medical Journal electronic databases was conducted (PROSPERO registration number CRD42024584536).

RESULTS

Twenty-two studies met the inclusion criteria, reporting 40 RFFF procedures in 40 patients (ages: 21-93, M:F 2.1:1). Of these, 65% (n=26) of the RFFFs were used for orbital socket reconstruction, with 75.7% (n=28) performed after cancer resection. The pooled success rate of the RFFFs in orbital and eyelid reconstruction was 92.8% (95% CI, 83.25 to 100, P = 0.39, I² = 5%) and the pooled complication rate was 8.62% (95% CI, 0% to 24.98%, P<0.01, I² = 78%). Flap failure occurred in 10% (n=4) of cases, primarily due to wound dehiscence (n=2).

CONCLUSIONS

RFFFs demonstrate success and complication rates comparable to traditional flaps used in eyelid and orbital reconstruction, such as the anterolateral thigh, rectus abdominis and latissimus dorsi flaps. It offers functional and cosmetic benefits, particularly for reconstruction after orbital exenteration. The RFFF is a reliable option for complex orbital and eyelid reconstructions and should be considered when local options are unavailable. Standardised reporting and further research are needed to validate long-term outcomes and minimise donor site complications.

Innovative use of radial artery retrograde forearm flap for oral and maxillofacial reconstruction

INTRODUCTION

The purpose of this study is to present a novel method of reconstructing oral and maxillofacial defects using the Radial Artery Retrograde Proximal Forearm Flap (RARPFF) and to evaluate the efficacy and safety of the forearm flap for direct closure of the donor site and its effect on hand function in the donor area.

METHODS

A prospective study of 30 patients who underwent oral and maxillofacial reconstruction with RARPFF between June 2021 and April 2024 was conducted to evaluate the safety and efficacy of the flap and its influence on hand function in the donor area.

RESULTS

Flap survival was 93.3 %. The donor site defect in 28 out of 30 patients healed primarily. All donor sites were directly closed without complications such as splitting, tendon exposure, or numbness in the thumb or thenar region. Statistically significant differences were observed in grip strength (MD = 4.56, p < 0.001) and elbow extension (MD = 2.78, p < 0.001) at 3 months, as well as in grip strength (MD = 2.20, p < 0.001) and elbow extension (MD = 1.67, p < 0.001) at 1 year, compared to the contralateral hand. Wrist flexion, extension, radial deviation, ulnar deviation, elbow flexion, pronation, and supination did not exhibit statistically significant differences from the contralateral hand at both 3 months and 1 year. The Michigan Hand Questionnaire (MHQ) revealed a statistically significant difference in aesthetics compared to the contralateral hand (p < 0.001), along with satisfactory overall hand function, activities of daily living (ADL), work performance, pain levels, and patient satisfaction with hand function.

CONCLUSIONS

The reverse radial artery proximal forearm flap is a dependable and secure technique for head and neck reconstruction. This method can effectively reduce donor site complications while preserving hand function.

A comparative prospective study between the outcomes of one-stage Pelnac reconstruction and full thickness skin graft on donor site healing in the radial forearm and fibula flaps

OBJECTIVES

Dermal substitutes are classically used in a 2-stage procedure followed by skin graft for wound healing. This study aims to evaluate the possibility to use an alternative technique for radial forearm and fibula donor sites coverage using one-stage Pelnac reconstruction.

MATERIALS AND METHODS

21 patients who underwent radial forearm and fibula flaps harvest for reconstruction of head and neck defects after oncological surgery were enroled in the study. 13 patients were treated by one-stage Pelnac reconstruction of the donor site defect, 8 patients underwent full thickness skin graft. The Vancouver Scar Scale was used to evaluate the scar quality.

RESULTS

Most patients treated with one-stage Pelnac reconstruction showed good healing of the flap donor site, with minor complications, scar quality comparable to other treatment options and unimpaired function of the implicated limb. One patient had wound dehiscence at the radial forearm site, which was treated with secondary full thickness skin graft. In the group treated with FTSG we had three patients that developed complications, such as dehiscence of the graft and seroma. Overall, we reported comparable satisfaction with donor sites both for aesthetic and functional outcomes, in both groups of patients.

CONCLUSION

The use of Pelnac without a following skin graft provides a viable method for the reconstruction of radial forearm and fibula flaps donor site. A longer postoperative care is needed, but the long-term aesthetic and functional results are satisfactory in comparison with full thickness skin graft.

Analysis of the Radial Forearm Phalloplasty Donor Site: Do Dermal Matrices Improve Donor Site Morbidity?

Background

The radial forearm free flap is frequently chosen for phalloplasty; however, flap size required for phalloplasty is associated with a large scar burden and functional concerns. We sought to investigate donor site functionality, aesthetics, and volume deficits in a cohort of individuals who underwent radial forearm phalloplasty (RFP) with donor site skin grafting alone or dermal substitute and subsequent skin grafting.

Methods

Donor site functionality was assessed using the quick Disabilities of Arm, Shoulder, and Hand (qDASH). Patient- and clinician-reported aesthetics were assessed using the Patient and Observer Scar Assessment Scale (POSAS). An Artec Leo three-dimensional scanner was used to measure volumetric differences from the donor site forearm and contralateral forearm.

Results

Fifteen patients who underwent RFP agreed to participate. No statistically significant differences were identified between different donor site closure methods regarding qDASH, patient-reported POSAS, or total volumetric deficits. A blinded clinician reported that POSAS approached significance at 4.7 for biodegradable temporizing matrix (BTM), 4.2 for Integra, and 3.0 for split-thickness skin graft (P = 0.05). No statistically significant differences were identified regarding distal, middle, or proximal volume deficits; however, a trend was observed regarding total volumetric deficits with BTM experiencing the lowest deficit (10.3 cm3) and skin graft experiencing the highest deficit (21.5 cm3, P = 0.82).

Conclusions

The addition of dermal matrix (BTM or Integra) to the treatment algorithm for RFP did not show statistically significant improvement in donor site volume deficits, patient-reported scar appearance (POSAS), or functionality (qDASH).

The implications for clinical practice advocate for a nuanced, patient-centered approach, incorporating emerging minimally invasive procedures and adjuvant therapies. The review concludes with recommendations for future research, emphasizing the importance of longitudinal studies, comparative analyses, patient-reported outcomes, advanced imaging techniques, and exploration of tissue engineering innovations. This synthesis advances our understanding of donor site morbidity and scar outcomes. It provides a roadmap for refining clinical protocols, ultimately enhancing the delicate balance between therapeutic efficacy and patient well-being in reconstructive surgery.

The use of artificial dermal substitutes for repair of the donor site following harvesting of a radial forearm free flap: A systematic review

BACKGROUND

Artificial dermal substitutes (ADMs) have been trialled to improve outcomes at the donor site following the harvesting of a radial forearm free flap (RFFF). This systematic review compares donor site aesthetic and functional outcomes, with the use of an ADM versus conventional practice.

METHODS

The databases Medline, Embase, Cochrane Library, Web of Science (Core Collection), and Scopus were searched for retrospective, prospective, and case-control studies and randomised control trials (RCTs) involving any ADM. Studies with adult patients having undergone RFFF harvesting and donor site repair with an ADM, commenting on appropriate clinical outcomes and without high risk of bias, were included. Direction-of-effect analysis was performed on relevant groupings of studies since heterogeneity in outcome measurement precluded meta-analyses.

RESULTS

Across eight non-comparative studies included, 132 patients had donor site coverage with AlloDerm™, Integra™, Matriderm™, or Rapiderm. Across 11 comparative studies included, 240 patients had donor site coverage with fish-skin matrix, AlloDerm™, amniotic membrane, MegaDerm™, Hyalomatrix, Integra™, or Matriderm™. Five out of 11 comparative studies demonstrated superior aesthetic outcomes with ADMs according to at least one aesthetic metric compared to controls, whilst 6/11 demonstrated superior functional outcomes with ADMs. No study demonstrated poorer aesthetic or functional outcomes with an ADM compared to conventional practice.

CONCLUSIONS

In summary, the lack of studies reporting poorer outcomes with them compared to conventional practices, and a cumulative effect direction in their favour, provide strong indications in support of the use of AlloDerm™, Integra™, or Matriderm™ grafts. Further comparative studies, including RCTs, are needed to reinforce these initial indications.

Comparison of the outcomes of split thickness skin graft versus thickness skin graft for closure of the radial forearm free flap donor site: A systematic review

BACKGROUND

Radial forearm free flap (RFFF) donor site closure is traditionally performed with split thickness skin grafts (STSG), which can be associated with poor aesthetics, wrist stiffness, paresthesia, reduced strength, and tendon exposure. Full thickness skin grafts (FTSG) are potentially beneficial as they provide a more durable coverage, and the skin graft donor site can be closed primarily, which is more aesthetic. The aim of this systematic review is to compare the outcomes of STSG versus FTSG for closure of the RFFF donor site.

METHODS

A systematic review was performed, following Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. The primary objective was to answer: do subjects undergoing RFFF harvest, utilizing FTSG to close the RFFF donor site, compared to STSG, achieve superior aesthetics at the RFFF donor site? Included papers compared FTSG and STSG with statistical data. Means were compared with t-test and proportions with Fisher's exact test.

RESULTS

The initial search resulted in 1851 studies. After applying the inclusion/exclusion criteria, the search resulted in eight studies, with 366 total skin grafts, 197 STSG and 169 FTSG. Six studies evaluated aesthetics utilizing a Likert scale, with the scaled average aesthetic score for FTSG being 7.9/10 compared to 6.9/10 for STSG (p < .001). Tendon exposure was measured in five studies, with a rate of 13.1% for STSG versus 10.6% for FTSG (p = .555). No significant difference in function was observed, however, methods to quantify function were heterogeneous.

CONCLUSION

FTSG compared to STSG, resulted in statistically significant improved aesthetics, with comparable rates of tendon exposure and function.

The superficial branch of the radial nerve and sensory disturbance in the radial forearm flap donor-site

Introduction

Sensory disturbance due to injury of the superficial branch of the radial nerve (SBRN) is a donor-site morbidity of the radial forearm (RF) flap. The relationship between the SBRN preservation method and the post-operative sensation at the flap donor-site was retrospectively investigated.

Methods

We included 39 patients who underwent head and neck reconstruction with a free RF flap at Hyogo Cancer Center between April 2014 and March 2018. The patients were classified into the following three groups according to the SBRN preservation method: group 1, zero preservation, excision of the entire SBRN; group 2, main trunk preservation, excision of all branches except the main trunk of the SBRN; and group 3, complete preservation, preservation of the entire SBRN. Objective sensations and subjective symptoms at the flap donor-site were analyzed.

Results

The mean objective sensory scores were 3.18, 2.97, and 1.78 in groups 1, 2, and 3, respectively. Differences between groups 1 and 3 and between groups 2 and 3 were significant (p = 0.0035 and p = 0.037, respectively). The mean subjective symptom scores were 2.40, 1.33, and 1.40 in groups 1, 2, and 3, respectively. Differences between groups 1 and 2, and between groups 1 and 3 were significant (p = 0.032 and p = 0.019, respectively).

Conclusions

Zero preservation method had a higher risk of subjective symptoms and objective hypoesthesia development at the flap donor-site than the complete preservation method. Despite inevitable objective hypoesthesia, the main trunk preservation prevented the development of subjective symptoms. Complete preservation is optimal for RF flap harvest; however, in case of perforator crossing, main trunk preservation is another option.

[Choice of flaps for phalloplasty: what is the contemporary standard? Consensus Statement of the German-Speaking Society for Microsurgery of Peripheral Nerves and Vessels]

The ever-expanding number of transmen as well as their surgeons share an increasing interest in the construction of a neophallus. While the indication for surgery and the positive effect of a phalloplasty on the quality of life, mental health and sexual function has already been thoroughly analysed, there is a lack of data comparing and evaluating the surgical steps. During the consensus conference on the "choice of flaps for phalloplasty" at the annual meeting of the German-Speaking Society for Microsurgery of Peripheral Nerves and Vessels, the current literature was discussed and a consensus on the surgical technique of a phalloplasty was reached. This manuscript publishes jointly developed recommendations on the following topics: choice of flaps for phalloplasty, preoperative diagnostic tests before phalloplasty, urethral construction in the radial forearm flap and anterior lateral thigh flap, preformation of the urethra at the forearm or thigh, venous drainage of the radial forearm flap, innervation of the phallus, staged phalloplasty, coronaplasty and managing the donor site of a radial forearm flap.

Bioengineered dermal matrix (Integra®) reduces donor site morbidity in total phallic construction with radial artery forearm free-flap

Total phallic construction with radial artery forearm free-flap (RAFFF) is widely regarded as the gold standard approach for phalloplasty. However, donor-site morbidity remains a significant concern, which is typically managed by using a full-thickness skin graft (FTSG) on the forearm. Split thickness skin grafts (STSG) have been proposed as an alternative, along with the use of an acellular dermal matrix substitute. A retrospective comparative analysis was performed to assess the differences in operative, functional and cosmetic outcomes between FTSG (Group A) and the combination of acellular dermal matrix with STSG (Group B). A retrospective cohort study was conducted on all patients who underwent total phallic construction with RAFFF, between 2016 and 2021. Post-operative surgical and functional outcomes were evaluated using validated tools. A total of 34 patients were included in the study, with 18 patients (52.9%) in Group A and 16 patients (47.1%) in Group B. Group B demonstrated a significant advantage in terms of healing time (24 days vs. 30 days, p = 0.003) and complete graft take (93.8% vs. 27.8%, p = 0.001). Group B also had significantly shorter operative times (310 min vs. 447 min, p = 0.001) and a reduced median hospital stay (8 days vs. 10 days, p = 0.001). Satisfaction with cosmesis was significantly higher in Group B (93.8% vs. 66.7%, p = 0.048).

Current and Future Developments in Wound Healing

Poor wound healing on the face and neck can lead to significant morbidity and dissatisfaction in facial plastic surgery. With current advances in wound healing management and commercially available biologic and tissue-engineered products, there are several options available to optimize acute wound healing and treat delayed or chronic wounds. This article summarizes some of the key principals and recent developments in wound healing research in addition to potential future advancements in the field of soft tissue wound healing.

Donor Site Defect Coverage of the Forearm with Dermal Substitute After Harvesting Radial Forearm Free Flap for Phalloplasty: Is MatriDerm® Worth the Effort?

An aesthetically and functionally pleasing phalloplasty is most commonly performed by a free radial forearm flap. However, the problem with donor site morbidity on the forearm remains unsolved. The aim of this study was to evaluate if the use of a dermal template such as MatriDerm® on the donor site significantly decreases the incidence of complications based on the Clavien–Dindo classification, such as wound healing disorders and reoperation rate, and if it could shortens the duration of hospital stay. A case series analysis was conducted at our institution. A total of 21 patients divided into two groups undergoing the phallic construction after the Gottlieb and Levine design in a single center underwent the donor site defect coverage either by MatriDerm® and split-thickness skin graft from the thigh or by full-thickness skin graft from the groin area. The use of MatriDerm® and split-thickness skin graft showed to have a statistically significant impact on the rate of complications (p = 0.008). Complications that were treated conservatively as well as that require surgical revision were significantly lower in the MatriDerm® group than in the full-thickness skin graft group (p = 0.002). Complications occurred not only at the forearm but also at the groin, where the full-thickness skin graft was harvested. The large dimension of the free radial forearm flap used for phalloplasty resulted in a significant donor site morbidity, leading to wound healing disorders, reoperations, and extended length of hospital stay. Therefore, we consider the use of dermal templates such as MatriDerm® as worth the additional effort and costs in this patient collective.

A Comparison of Skin Graft Techniques with and without Plaster Back Slab Dressing in Reducing Donor Site Morbidity in Radial Forearm Free Flap Surgery - A Retrospective Study

Introduction

The radial forearm free flap (RFFF) is a commonly used free flap for the reconstruction of orofacial defects because of its versatility and reliability. The donor site is closed with either split or full-thickness skin graft, and one of the common donor site morbidities is skin graft failure. Various techniques to minimise skin graft failure were reported, and we compared the skin graft techniques with and without plaster back slab dressing in the radial forearm donor site.

Materials and Methods

This is a retrospective study of 75 patients who had RFFF for reconstruction of oral cavity cancer at two different tertiary teaching hospitals in the United Kingdom between April 2015 and March 2020. Thirty-nine patients from Hospital one had volar back slap, bolster dressing and crepe bandage. In contrast, 36 patients from Hospital two had only pressure dressing without a back slab.

Results

The mean age of the study population was 60.65 (P = 0.274). In both groups, two patients had donor site complications. However, there was no significant difference in the donor site skin graft complications with a P = 0.662.

Discussion

There was no evidence in the literature to support an ideal bandage for skin graft at the RFFF donor site. Our comparison of two techniques of skin graft dressings with and without back slap did not show any difference in the skin graft take, and the volar back slab did not add any additional benefits. The simple use of foam as a bolster dressing without a back slab is ideal for the radial forearm free flap donor site.

Reducing morbidity in radial forearm free flap donor site: a review of closure techniques

PURPOSE

Radial forearm free tissue transfer (RFFF) has been an extremely reliable reconstructive option for head and neck oncologic defects for over 30 years. With high reliability, interest has shifted in minimizing donor site morbidity, much of which results from closure techniques.

RECENT FINDINGS

Portable negative pressure wound devices, newer dermal substitutes, and local flap techniques have improved donor site aesthetics and function.

SUMMARY

Outcomes of the RFFF donor site may benefit from newer techniques in closure.

Multimodal evaluation of donor site morbidity in transgender individuals after phalloplasty with a free radial forearm flap: a case-control study

BACKGROUND

In phalloplasty, there is a lack of standardized follow-up examinations of motor function and strength after harvesting oversized radial forearm free flaps (RFFF).

METHODS

We evaluated the donor site of 20 transmen after phalloplasty, using a multimodal, standardized approach, assessing the following parameters: opposition of the thumb, composite range of motion of the finger joints, grip strength, mobility of the wrist, lesion of the superficial branch of the radial nerve, the dorsal branch of the ulnar nerve, the sensation of pain, and cold intolerance. The contralateral, nonoperated forearm was used as a control.

RESULTS

No impairment of the mobility of the thumb (Kapandji score median 10, range 5-10) or fingers (all fingers at both sides pulp-to-palm 0 cm, nail-to-table 0 cm) were detected. Grip strength (median 36,3kg, p=0.629) and wrist extension (62.5°vs.70°, p=0.357), flexion (70°vs.70°, p=0.535), pronation (90°vs.90°), supination (90°vs.90°), radial (30°vs.30°, p=0.195), and ulnar deviation (40°vs.50°, p=0.125) did not statistically differ between donor and control hand. Injury of the dorsal branch of the ulnar nerve was uncommon (0% hypoesthesia, 10% positive Tinel's sign). We did not observe any persistent pain of the donor forearm (NRS median 0, range 0-9). We did observe irritation of the superficial branch of the radial nerve (hypoesthesia 40%, neuroma 45%).

CONCLUSION

The harvest of an oversized RFFF for phalloplasty does not cause any significant difference in motor function or strength between the donor and nonoperated hand. A potential risk of injuring the radial nerve branch is to be avoided. An aesthetic impairment could be addressed in future studies.

Total phallic construction techniques in transgender men: an updated narrative review

From 2012, the World Professional Association Transgender Health defined a structured therapeutic path and standards of care for transgender patients undergoing genital gender affirming surgery (GGAS). The main goal of GGAS in transgender males is to provide patients with an aesthetically appealing appearance of the neophallus that should allow standing micturition and enabling penetrative intercourse along with erogenous and tactile sensitivity. The optimal procedure should be safe, reproducible and performed in the fewest number of surgical stages. The ideal technique for total phallic construction (TPC) has not yet been demonstrated; TPC remains challenging and, from a functional point of view, it is also make more demanding as yet there are no perfect replacement materials for erectile and urethral tissues. Several procedures and different type of flaps (pedicled and free-flaps) have been proposed and investigated over time to address TPC with significant advances over the years especially after microsurgical procedures introduction. Due to its high complexity TPC is not free from complications. Local tissue ischaemic complications, complete and partial flap loss, donor site morbidity and urethral complications (fistulae and strictures) are reported. This narrative review aims to provide the readers with a contemporary overview of surgical procedures for TPC in transgender males focusing on key surgical steps, as well as surgical and functional outcomes.

Closure of the radial forearm free flap donor site with split-thickness skin graft or amniotic membrane: A prospective randomized clinical study

The purpose of this study was to compare the clinical, aesthetic, and functional outcomes between amniotic membrane (test group) and split-thickness skin grafts (control group) used for radial forearm free flap defect closure. The primary outcome measurement for both groups was assessment of the defect closure healing process. In addition, aesthetic (Vancouver Scar Scale) and functional outcomes (skin sensitivity, hand/wrist functionality, grip strength) were evaluated. Fifty eligible patients with radial forearm free flap donor site defects were randomly assigned to two groups receiving either amniotic membrane (test group; n = 25) or split-thickness skin graft (control group; n = 25) for defect covering. Forty-seven of the 50 patients (n = 47) were able to be followed up for 6 months and showed a significantly longer healing process (p < 0.001) with amniotic membrane (64.5 ± 38.4 days; n = 24) than with split-thickness skin grafts (29.2 ± 8.9 days; n = 23); however, there were no differences in the prevalence of healing defects/dehiscence and/or wound infections. Forty-two of the 47 patients (21 in each group) were able to be continually followed up for 12 months, and showed no differences in terms of clinical outcome as well as the subjective and objective aesthetic and functional results evaluated. With regard to the clinical, aesthetic, and functional outcomes evaluated for radial forearm free flap defects, coverage with amniotic membrane offers an excellent alternative treatment approach, avoiding secondary induced donor site morbidity.

Long-term donor site morbidity after radial forearm flap elevation for tongue reconstruction: Prospective observational study

BACKGROUND

To assess long-term donor site morbidity after radial forearm free (RFF) flap harvesting.

METHODS

Enrolled patients were asked to complete the Disability of the Arm, Shoulder, and Hand (DASH) questionnaire and undergo wrist motion and hand strength examinations at different time points. The data were prospectively collected and retrospectively analyzed.

RESULTS

The postoperative DASH score did not return to normal until 24 months after the operation. The mean postoperative wrist motion degree of flexion was significantly decreased compared to the preoperative level and returned to normal at 12 months after the operation. Similar trends were noted regarding extension, radial abduction, and ulnar abduction. The mean postoperative grip strength was significantly decreased compared to the preoperative level and remained dysfunctional at 24 months after the operation. A similar trend was also noted with regard to tip pinch and key pinch.

CONCLUSION

The long-term negative effect on hand strength is sustained.

[Microsurgical penile reconstruction in case of intersexuality and after penis carcinoma]

BACKGROUND

 The goals of penile reconstruction and phalloplasty include aesthetics as natural as possible and the ability of patients to void while standing and to have sexual intercourse. This article presents two more rare indications and techniques, the phalloplasty using free radial forearm flapin case of intersexuality and after penectomy due to penis carcinoma.

PATIENTS AND METHODS

 In transsexual individuals numerous phalloplasties in Gottlieb and Levine`s technique, by means phalloplasty of free radial forearm-flap of the non-dominant forearm, were performed in our department over the last few years. However, this technique also has its significance for phalloplasty in non-transgender persons.Two patients are considered in detail with regard to indication and surgical technique and were followed up in a multimodal setting.Patient 1 is genetically male, thirty-five years old with a micropenis in the case of pseudohermaphroditism masculine and androgen resistance.Patient 2 is a fifty-one-year old genetically male and as a result of a penis carcinoma his penis had to be amputated at the level of penis root. After absence of recurrence for 1,5 years, the penile reconstruction took place after complete resection of the remaining residual penile stump and corpora cavernosa. Both patients underwent multimodal follow-up 15 months postoperatively with regard to phalloplasty sensors and donor-site restrictions.

RESULTS

 An aesthetic and functional acceptable result could be obtained for both patients. Both patients are able to void while standing. The multimodal follow-up 15 months postoperatively revealed relevant differences in the sensory findings of both patients, which are due to the different anatomy of reinnervation.

CONCLUSION

 In microsurgical experienced departments, the technique of A. radialis phalloplasty can also be used successfully in more rare indications, as shown here, a satisfying result can be achieved in terms of function and aesthetics. The complications shown here do not differ from those using phalloplasty in transgender persons.

Use of amniotic membrane for radial forearm free flap donor site coverage: clinical, functional and cosmetic outcomes

Objective

To evaluate the clinical, functional and aesthetic outcomes for radial forearm free flap (RFFF) donor sites covered with amniotic membrane (AM).

Material and methods

The healing process of patients with RFFF donor sites covered with AM was prospectively followed for 1 year. Additionally at the 12-month evaluation, objective scoring systems were used to assess the aesthetic (Vancouver scar scale, VSS: range 1–13) and functional outcome (skin sensibility, hand/wrist functionality [goniometer], grip strength [score 1 = excellent, 5 = poor]). By using a subjective rating system (score 1 = excellent, 5 = poor), the patient-reported aesthetic and functionality outcome was correlated with objective data analysis.

Results

Twenty-one out of 23 patients were followed for 12 months (dropout: 2 patients at 3 months). In 17/23 (73.9%) patients RFFF defect covered with AM showed an uneventful healing period (< 3 months). Prolonged healing periods (> 3 months < 6) for 6 patients (26.1%) were attributed to wound infections (4×), seroma (1×) and inflammation (1×). At the 1-year evaluation, there was a significant (p < 0.01) correlation between subjective (2.0 ± 0.71) and objective aesthetic scores (VVS 3.74 ± 2.18), and a successful grip strength (score 1.67 ± 0.86); however, thumb hyposensibility in 76.2% was seen. A high body mass index (BMI) was in conjunction with a negative (p = 0.012) and the use of antihypertensive medications provided positive effects (p = 0.041) on the aesthetic outcome.

Conclusion

RFFF donor site defects covered using AM show excellent clinical, aesthetic and functional outcome representing patient comorbidities (BMI, antihypertensive drugs) might affect the aesthetic outcome.

Clinical relevance

In relation to the excellent outcomes found, the use of AM offers an alternative treatment procedure for RFFF defect covering.

Revision surgery with dermal regeneration template and vacuum sealing drainage for reconstruction of complex wounds following necrosis of reattached avulsed skins in a degloving injury: A case report

RATIONALE

Degloving injury of the upper limb often extends to underlying tendons and bone, which is at high risk of treatment failure if only simple reattachment of defatted avulsed skins was performed. Pelnac dermal regeneration template could be used as a treatment choice for necrosis of the reattached avulsed skins in a degloving injury.

PATIENT CONCERNS

A 48-year-old woman with a degloving injury of the right forearm, wrist, and hand received initial treatment by reattachment of the defatted avulsed skins over the wound bed. However, 17 days postoperatively, the reattached skins developed complete necrosis, leaving large size of tissue defects and tendon/bone exposure.

DIAGNOSIS

Failure to reconstruct the skin and soft-tissue envelop by reattachment of the defatted avulsed skins in a severe degloving injury of the upper limb.

INTERVENTIONS

We decided to use a 2-stage procedure of Pelnac dermal regeneration template and secondary skin graft to solve this issue, in consideration of these conditions and the patient' demanding of limb function and aesthetic appearance.

OUTCOMES

At the final follow-up, this patient obtained an excellent result, in term of scar quality, aesthetic appearance, and the ability to perform the daily activities.

LESSONS

We believe this could become an interesting option in patients who needed revision procedure for management of complex wounds with tendon/bone exposure following the necrosis of reattached skins in degloving injuries.

[Rotation and advancement of the radial-based fasciocutaneous flap for primary closure of the radial forearm flap donor defect]

OBJECTIVE

This study aims to investigate the feasibility and clinical application value of a new method for primary donor-site closure of radial forearm flaps with the use of rotation and advancement of radial-based fasciocutaneous flaps.

METHODS

The forearm donor-site defects of 36 patients were primarily closed by rotation and advancement of radial-based fasciocutaneous flaps after radial flap harvest from November 2014 to May 2015. Patients included 28 males and 8 females aged 28 to 67 years (53.6 years old on average). Flap size ranged from 3.0 cm×5.0 cm to 4.0 cm×6.0 cm. Wound healing, scar hyperplasia, and forearm appearance were recorded and evaluated. Wrist flexion angle, dorsal extension angle, ulnar deviation angle, and radial deviation angle were measured three and six months after the operation. Wrist joint loss index was calculated and compared with the preoperative index to evaluate wrist function recovery. The results were subjected to comparative t-
test to perform statistical analysis with SPSS 19.0 statistical software package.

RESULTS

Forearm donor sites were successfully closed without skin grafting in all patients. Skin ischemia caused by excessive tension was observed at the incision edge in five cases, thereby leading to skin exfoliation and pigment loss without affecting wound healing. All patients were followed up at six and twelve months, and presented a satisfactory appearance. No scar hyperplasia was observed. No significant difference was observed in radial deviation, ulnar deviation, palmar flexion, dorsiflexion, radial deflection angle, or wrist joint loss index (P>0.05) after the operation.

CONCLUSIONS

Application of rotation and advancement of radial-based fasciocutaneous flaps can directly close small-to-medium radial forearm flap donor defects. Satisfactory postoperative appearance can be achieved with no loss in wrist joint function. The novel method prove worthy of promotion and application in clinical work.

Oral and Oropharyngeal Reconstruction with a Free Flap

Extensive surgical resection of the aerodigestive track can result in a large and complex defect of the oropharynx, which represents a significant reconstructive challenge for the plastic surgery. Development of microsurgical techniques has allowed for free flap reconstruction of oropharyngeal defects, with superior outcomes as well as decreases in postoperative complications. The reconstructive goals for oral and oropharyngeal defects are to restore the anatomy, to maintain continuity of the intraoral surface and oropharynx, to protect vital structures such as carotid arteries, to cover exposed portions of internal organs in preparation for adjuvant radiation, and to preserve complex functions of the oral cavity and oropharynx. Oral and oropharyngeal cancers should be treated with consideration of functional recovery. Multidisciplinary treatment strategies are necessary for maximizing disease control and preserving the natural form and function of the oropharynx.

Comparative Study of the Free Microvascular Groin Flap: Optimizing the Donor Site After Free Radial Forearm Flap Phalloplasty

OBJECTIVE

To improve the donor-site morbidity of the radial forearm flap through coverage with a free vascularized groin flap and comparing this flap coverage to the current standard, a full-thickness skin graft (FTSG).

MATERIALS AND METHODS

A retrospective analysis of all free radial forearm flap phalloplasties for transgender surgery at our institution was performed. We examined patient characteristics, donor site defects, surgical procedure, and clinical courses.

RESULTS

Between October 2013 and February 2016, 27 consecutive patients underwent phalloplasty for female-to-male reassignment surgery with free radial forearm flaps. A total of 7 free groin flaps (group A) and 20 full-thickness skin graft from the groin region (group B) for donor-site defect coverage of the forearm were performed. The mean age in group A was 28.4 years with a mean body mass index of 21.6 kg/m(2) and a mean follow-up time of 10.6 months. The mean surgery time was 724 minutes. The mean patients' functional rating was 3.6 accompanied by the mean patients' aesthetical rating of 3.7. The mean age in group B was 30.5 years with a mean body mass index of 23.7 kg/m(2) and a mean follow-up time of 13.4 months. The mean surgery time was 563 minutes. The mean patients' functional rating was 3.1 accompanied by the mean patients' aesthetical rating of 2.9.

CONCLUSION

We suggest that the free microvascular groin flap should be considered for immediate defect closure after phalloplasty with a radial forearm flap due to its beneficial functional and aesthetic results and the low rate of complications.

Double-layered collagen graft to the radial forearm free flap donor sites without skin graft

Background

Radial forearm free flap is the most reliable flap for intraoral soft tissue reconstruction after cancer ablation surgery. However, unesthetic scar of the donor site and the need for a second donor site for skin graft are major disadvantages of the forearm flap. The purpose of this study was to report the clinical results of double-layered collagen graft to the donor site of the forearm free flap without skin graft.

Methods

Twenty-two consecutive patients who underwent oral cancer ablation and forearm reconstruction between April 2010 and November 2013 were included in this study. Male to female ratio was 12:10, and average age was 61.0 years old (27–84). Double-layered collagen was grafted to the donor site of the forearm free flap and healed for secondary intention. Upper silicone had been trimmed at the periphery during secondary intention, and dry dressing was used. Postoperative scar healing and esthetic results and function were evaluated.

Results

An average follow-up period was 34.9 months. The scar area was decreased to 63.9 % in average. The complete healing was obtained between 1.5 and 3 months according to the defect size. There was no functional defect or impairment 3 months after operation. All patients were satisfied with the esthetic results. Three patients died of recurred cancer.

Conclusions

Double-layered collagen graft was successfully performed in this study. Without the thigh skin graft, patients had experienced less painful postoperative healing periods and discomfort.

A biodegradable polyurethane dermal matrix in reconstruction of free flap donor sites: a pilot study

We have developed a biodegradable temporizing matrix (BTM) capable of supporting secondary split-skin graft-take in animal studies. We report its first long-term implantation and use as a dermal scaffold in humans. This preliminary study assesses its ability to integrate, its ease of delamination, its ability to sustain split-skin graft in complex wounds, the degree of wound contraction, and ultimately the quality of the scar at 1 year postimplantation. Ten patients were recruited, each requiring elective free flap reconstruction. Free flap donor sites created were anterolateral thigh flaps, fibular osseocutaneous flaps, or radial/ulnar forearm (RF/UF) flaps. The BTM was implanted when the flap was detached from its donor site. Dressing changes were performed twice weekly. The time elapsed between implantation and delamination depended on the type of flap and thus the wound bed left. Once integrated, the BTMs were delaminated in theatre, and the surface of the "neodermis" was refreshed by dermabrasion, prior to application of a split-skin graft. The BTM integration occurred in all patients (100% in 6 patients, with 90%, 84%, 76%, and 60% integration in the remainder). Integrated BTM sustained successful graft-take in all patients. Complete take was marred in 2 patients, over areas of BTM that had not integrated and graft application was performed too early. The BTM can be applied into wounds in humans and can integrate, persist in the presence of infection, and sustain split-skin overgrafting, despite the trial group presenting with significant comorbidities.

Use of integra artificial dermis to reduce donor site morbidity after pedicle flaps in hand surgery

PURPOSE

To assess the results obtained with Integra artificial dermis to cover donor site following the harvesting of pedicle flaps for hand reconstruction.

METHODS

Between April 2010 and August 2013, 11 patients (8 men and 3 women; mean age, 37 y) were treated with Integra Dermal Regeneration Template (Integra LifeSciences, Inc., Plainsboro, NY) to cover donor defects after raising pedicle flaps for hand and finger reconstruction: radial forearm flap (4 cases), ulnar artery perforator flap (2 cases), and heterodigital island flap (5 cases). After neodermis formation the silicone layer of the artificial dermis was removed (on average after 22 days) and a split- or full-thickness epidermal autograft placed.

RESULTS

No infections, hematoma, or bleeding were recorded during the entire phase in which the artificial skin was applied. Two patients experienced a partial skin graft loss. Median follow-up was 20 months, and results included an average Vancouver Scar Scale rating of 2.7 and an average DASH score of 39. There were no cases of graft adherence to the underlying tendons or muscles.

CONCLUSIONS

Favorable cosmetic and functional outcomes were obtained using a dermal regeneration template for the treatment of donor site defects. Despite the drawback of an additional surgical procedure (secondary skin graft), the use of this artificial skin produced soft-tissue augmentation and graft-skin quality, reducing donor site morbidity.
