Reverse peroneal artery flap for large defects of ankle and foot: A reliable reconstructive technique

Background:

Large soft tissue defects around the lower third of the leg, ankle and foot always have been challenging to reconstruct. Reverse sural flaps have been used for this problem with variable success. Free tissue transfer has revolutionised management of these problem wounds in selected cases.

Materials and Methods:

Twenty-two patients with large defects around the lower third of the leg, ankle and foot underwent reconstruction with reverse peroneal artery flap (RPAF) over a period of 7 years. The mean age of these patients was 41.2 years.

Results:

Of the 22 flaps, 21 showed complete survival without even marginal necrosis. One flap failed, where atherosclerotic occlusion of peroneal artery was evident on the table. Few patients had minor donor site problems that settled with conservative management.

Conclusions:

RPAF is a very reliable flap for the coverage of large soft tissue defects of the heel, sole and dorsum of foot. This flap adds versatility in planning and execution of this extended reverse sural flap.KEY WORDS: Distally based peroneal flaps, extended reverse sural flaps, foot reconstruction, peroneal artery, reverse peroneal flaps     

Experience with peroneus brevis muscle flaps for reconstruction of distal leg and ankle defects

Objective:

Peroneus brevis is a muscle in the leg which is expendable without much functional deficit. The objective of this study was to find out its usefulness in coverage of the defects of the lower leg and ankle.

Patients and Methods:

A retrospective analysis of the use of 39 pedicled peroneus brevis muscle flaps used for coverage of defects of the lower leg and ankle between November 2010 and December 2012 was carried out. The flaps were proximally based for defects of the lower third of the leg in 12 patients and distally based for reconstruction of defects of the ankle in 26 patients, with one patient having flaps on both ankles.

Results:

Partial flap loss in critical areas was found in four patients requiring further flap cover and in non-critical areas in two patients, which were managed with a skin graft. Three of the four critical losses occurred when we used it for covering defects over the medial malleolus. There was no complete flap loss in any of the patients.

Conclusion:

This flap has a unique vascular pattern and fails to fit into the classification of the vasculature of muscles by Mathes and Nahai. The unusual feature is an axial vessel system running down the deep aspect of the muscle and linking the perforators from the peroneal artery and anterior tibial artery, which allows it to be raised proximally or distally on a single perforator. The flap is simple to raise and safe for the reconstruction of small-to moderate-sized skin defects of the distal third of the tibia and all parts of the ankle except the medial malleolus, which is too far from the pedicle of the distally based flap. The donor site can be closed primarily to provide a linear scar. The muscle flap thins with time to provide a good result aesthetically at the primary defect.KEY WORDS: Ankle defects, lateral malleolus defects, lower leg defect, muscle flap, peroneus brevis flap, pedicle flap, tendo achilles defects     

Skin paddle vascularity of free fibula flap �C A study of 386 cases and a classification based on contribution from axial vessels of the leg

Objective:

The skin paddle of the free fibula flap receives its vascular supply from septocutaneous perforators, musculocutaneous perforators or from both, and these perforators might originate from the peroneal or posterior tibial vessels or from both. The objective of this study was to classify the skin paddles based on the dominance of vascular contribution by these axial vessels through their different perforator systems.

Materials and Methods:

A retrospective analysis of 5-year data of 386 free fibula flaps used in oro-mandibular reconstruction was done and the skin paddle vascularity was studied. While majority of the skin paddles received their blood supply from the peroneal septocutaneous perforators, a few had their dominant supply from the soleus musculocutaneous perforators in addition to peroneal septocutaneous perforators. In few cases, the soleus musculocutaneous perforators were the sole source of blood supply to the skin paddle. The limitation in this study was the inability to augment the clinical observation with cadaveric study.

Results:

The skin paddle of the free fibula flap was classified into four different types (a–d) based on the dominance of vascular contribution by axial vessels of the leg.

Conclusion:

The skin paddle of the free fibula flap has reliable blood supply, but a thorough knowledge of the variations in vascular pattern of the skin paddle is required especially to salvage the larger paddles used in the reconstruction complex oro-mandibular defects.KEY WORDS: Free fibula flap, musculocutaneous perforators, septo cutaneous perforators, skin paddle, vascular supply     

Outcome of free digital artery perforator flap transfer for reconstruction of fingertip defects

Background:

Fingertip defect can be treated with many flaps such as random pattern abdominal flap, retrograde digital artery island flap, V-Y advancement flap, etc. However, swelling in the fingertip, dysfunction of sensation, flexion and extension contracture or injury in the hemi-artery of the finger usually occurs during the recovery phase. Recently, digital artery perforator flaps have been used for fingertip reconstructions. With the development of super microsurgery techniques, free flaps can be more effective for sensory recovery and durability of the fingertip.

Materials and Methods:

Six cases (six fingers) of fingertip defects were treated with free digital artery perforator flaps of appropriate size and shape from the proximal phalanx. During surgery, the superficial veins at the edge of flap were used as reflux vessels and the branches of the intrinsic nerve and dorsal digital nerve toward the flap were used as sensory nerves. The proximal segment of the digital artery (cutaneous branches) towards the flap was cut off to form the pedicled free flap. The fingertips were reconstructed with the free flap by anastomosing the cutaneous branches of digital artery in the flap with the distal branch or trunk of the digital artery, the flap nerve with the nerve stump and the veins of the flap with the digital artery accompanying veins or the superficial veins in the recipient site.

Results:

Six flaps survived with successful skin grafting. Patients were followed up for 6-9 months. The appearance and texture of the flaps was satisfactory. The feeling within the six fingers recovered to S4 level (BMRC scale) and the two point discrimination was 3-8 mm.

Conclusion:

Free digital artery perforator flap is suitable for repairing fingertip defect, with good texture, fine fingertip sensation and without sacrificing the branch of the digital artery or nerve.     

An assessment of the anatomical basis of the thoracoacromial artery perforator flap

BACKGROUND:

Musculocutaneous perforator flaps offer advantages over musculocutaneous flaps, including reduced donor site morbidity, more predictable reconstruction of soft tissue deformities, and a wider variety of flap options. Perforator flaps are becoming increasingly popular for many applications. In the present study, we set out to examine the various perforators of the thoracoacromial axis through the pectoralis major (PM) muscle with respect to their suitability for transfer to the head and neck region as a pedicled flap.

METHODS:

A series of 10 fresh cadavers were injected with lead oxide, gelatin and water (250 mL/kg) through the femoral vessels. The cadavers were cooled and the integument was removed. Perforating vessels from the underlying muscles were marked and the resulting angiograms of the integument and deep tissues were compared with the dissection notes describing the course, size and distribution of the perforating vessels.

RESULTS:

The perforators through the PM muscle to the overlying skin included three regional groups: perforators of the thoracoacromial axis; perforators of the medial intercostal vessels; and perforators of the lateral thoracic artery. The major group of perforators supplying the overlying skin was from the intercostal vessels. However, the thoracoacromial axis did consistently give rise to perforators in the upper portion of the PM muscle. In particular, there were reliable perforators from the clavicular and deltoid branches of the thoracoacromial artery.

DISCUSSION:

The present study illustrates the potential clinical applications of a series of perforator flaps based on the thoracoacromial axis, which may be useful in head and neck reconstructive surgery.     

CT angiographic evaluation of perforators in the lower limb and their reconstructive implication

Background:

The perforator flaps evolved on the knowledge of the vascular tree from the main vascular trunk up to the subdermal plexus. Therefore, we thought that it''s necessary to map the whole vascular arcade by CT angiography. The aim of this study is to evaluate the perforators and the whole vascular tree of the lower limb by peripheral CT angiography with 3D reconstruction and intraoperative evaluation. This study helps in designing flaps of different constituents based on the selected perforators.

Materials and Methods:

Twenty patients having lower limb defects were selected. CT angiography was done using a non-ionic iodinated contrast media injected through the antecubital vein. The lower limbs were imaged using volume rendering CT scan machine. Three dimensional reconstructions were made. The whole arterial tree, along with the perforators, were mapped. Findings of the audio-Doppler were correlated with the CT angiographic observations. Further these evaluations were confirmed by intraoperative findings.

Results:

The three dimensional CT angiographic reconstruction with bone and soft tissue provided advanced knowledge of this vascular network. It delineated the main vessel, the perforators, their caliber, distance from fixed bony landmarks and course up to the subdermal plexus. These findings were confirmed during dissection of the proposed flap. The perforators were mainly musculocutaneous in the proximal leg and septocutaneous distally.

Conclusions:

The vascular details visualized by this technique made advancement over the existing methods namely color Doppler, audio Doppler, two dimensional angiography etc. It improved the understanding of perforator flaps and their successful clinical application.KEY WORDS: CT angiography, lower limb, perforator, reconstruction     

Free style perforator based propeller flaps: Simple solutions for upper extremity reconstruction!

Background:

The introduction of perforator flaps by Koshima et al. was met with much animosity in the plastic surgery fraternity. The safety concerns of these flaps following the intentional twist of the perforators have prevented widespread adoption of this technique. Use of perforator based propeller flaps in the lower extremity is gradually on the rise, but their use in upper extremity reconstruction is infrequently reported, especially in the Indian subcontinent.

Materials and Methods:

We present a retrospective series of 63 free style perforator flaps used for soft tissue reconstruction of the upper extremity from November 2008 to June 2013. Flaps were performed by a single surgeon for various locations and indications over the upper extremity. Patient demographics, surgical indication, defect features, complications and clinical outcome are evaluated and presented as an uncontrolled case series.

Results:

63 free style perforator based propeller flaps were used for soft tissue reconstruction of 62 patients for the upper extremity from November 2008 to June 2013. Of the 63 flaps, 31 flaps were performed for trauma, 30 for post burn sequel, and two for post snake bite defects. We encountered flap necrosis in 8 flaps, of which there was complete necrosis in 4 flaps, and partial necrosis in four flaps. Of these 8 flaps, 7 needed a secondary procedure, and one healed secondarily. Although we had a failure rate of 12-13%, most of our failures were in the early part of the series indicative of a learning curve associated with the flap.

Conclusion:

Free style perforator based propeller flaps are a reliable option for coverage of small to moderate sized defects.

Non-microsurgical skin flaps for reconstruction of difficult wounds in distal legand foot

Purpose

To express the versatility of a variety of non-microsurgical skin flaps used for coverage of difficult wounds in the lower third of the leg and the foot over 4 years period. Five kinds of flaps were used. Each flap was presented with detailed information regarding indication, blood supply, skin territory and technique.

Reconstruction of soft tissue defects in the Achilles tendon region with perforator-based fasciocutaneous flaps

Background

Reconstruction of soft tissue defects in the Achilles tendon region can be technically demanding. Perforator-based flaps can be an effective local solution, replacing like-for-like skin. We report our experience with perforator-based flap reconstruction of the Achilles tendon region with or without rupture of the Achilles tendon.

Methods

Between January 1999 and 2011, 11 patients had perforator-based flaps based on peroneal and posterior tibial perforators. There were six V-Y advancement flaps, four propeller flaps and one peninsular flap. The mean defect size was 19.3 (range 9–36)?cm². One patient had reconstruction of a composite Achilles tendon defect.

Results

There were no flap failures. Mean follow-up was 26.4 (range 3–120)?months. Post-operative complications included haematoma in one patient and dehiscence of wound because of further sloughing of the tendon—at the distal edge of a V-Y advancement flap. This patient needed a second local flap. There were no wound breakdowns, painful sensitivity or difficulty with walking. All patients who had skin and soft tissue reconstruction only were partially weight bearing by 2 weeks and gradually increased weight bearing and fully weight bearing by 4 weeks.

Conclusions

Perforator-based flaps are a robust method of covering small- to medium-sized defects in the Achilles tendon region. Presence of multiple perforators on either side of the Achilles tendon invites a number of flap designs, tailored to the defect. Level of Evidence: Level IV, Therapeutic study.     

Perforator plus flaps: Optimizing results while preserving function and esthesis

Background:

The tenuous blood supply of traditional flaps for wound cover combined with collateral damage by sacrifice of functional muscle, truncal vessels, or nerves has been the bane of reconstructive procedures. The concept of perforator plus flaps employs dual vascular supply to flaps. By safeguarding perforators along with supply from its base, robust flaps can be raised in diverse situations. This is achieved while limiting collateral damage and preserving nerves, vessels, and functioning muscle with better function and aesthesis.

Materials and Methods:

The perforator plus concept was applied in seven different clinical situations. Functional muscle and fasciocutaneous flaps were employed in five and adipofascial flaps in two cases, primarily involving lower extremity defects and back. Adipofascial perforator plus flaps were employed to provide cover for tibial fracture in one patients and chronic venous ulcer in another.

Results:

All flaps survived without any loss and provided long-term stable cover, both over soft tissue and bone. Functional preservation was achieved in all cases where muscle flaps were employed with no clinical evidence of loss of power. There was no sensory loss or significant oedema in or distal to the flap in both cases where neurovascular continuity was preserved during flap elevation. Fracture union and consolidation were satisfactory. One patient had minimal graft loss over fascia which required application of stored grafts with subsequent take. No patient required re-operation.

Conclusions:

Perforator plus concept is holistic and applicable to most flap types in varied situations. It permits the exercise of many locoregional flap options while limiting collateral functional damage. Aesthetic considerations are also addressed while raising adipofascial flaps because of no appreciable donor defects. With quick operating times and low failure risk, these flaps can be a better substitute to traditional flaps and at times even free tissue transfers.     

Augmented repair of acute tendo Achilles ruptures with gastrosoleus turn down flap

Background:

We present the results of primary repair of acute tendo Achilles (TA) rupture augmented with gastrosoleus turn down flap technique.

Patients and Methods:

78 consecutive patients with a complete acute rupture of the Achilles tendon operated between 1993 and 2004 were included in study. We performed a modification of the Lindholm technique in which the primary Kessler suture repair of the tendon was augmented by a turn-down ~3 cm × 10 cm gastrosoleus aponeurosis flap. In all cases, a short-leg circular walking cast was applied at 90° of the ankle dorsiflexion for 3 weeks and all the patients were encouraged to full weightbearing ambulation immediately. After removal of the cast, isometric and isokinetic ankle exercises were performed for 3 weeks. Modified Rupp Score was used to evaluate the subjective satisfaction.

Results:

All of patients returned to daily activity and 54 (69%) of them returned to previous sport activity. The tendon repair failed in two patients and they were reoperated with an allograft. Three patients developed infection and one of them required débridement. One developed deep venous thrombosis and two permanent sural nerve injuries were encountered. One of the patients had a severe skin necrosis, which was treated with rotation flap. The mean Rupp score was 29 (3–33).

Conclusion:

Primary repair of acute tendo Achilles rupture augment with gastrosoleus turn down flip technique in combination of immediate weightbearing ambulation provides a good outcome, but is associated with similar complication rates to the previous literature.     

Distally based perforator flaps for reconstruction of post-traumatic defects of the lower leg and foot. A review of the anatomy and clinical outcomes

Study aims

To report the surgical anatomy of the perforator arteries at the lower leg, analyse clinical outcomes in previous studies, and forward methodological recommendations for future studies of post-traumatic perforator flap reconstructions.

Methods

A study sample of 640 human patients drawn from 24 clinical reports was included for review. The sample comprised of four subsets: sural flap reconstructions (n = 257), saphenous flaps (n = 122), supramalleolar flaps (n = 92), and propeller flaps (n = 169).

Results

Statistical analysis of samples from anatomical studies documents significant differences in the perforator distribution from the tibial and peroneal artery; peroneal perforator arteries are randomly organised whereas tibial artery perforators are clustered at three definite levels. The failure rates in clinical studies ranged from 0% to 6%, being lowest for supramalleolar flap reconstructions and highest for saphenous flaps; however, differences between the four subsets were not statistically significant at the 95% confidence level. Due to methodological flaws, outcome comparisons in the actual study sample should be interpreted cautiously; in most clinical studies both risk variables and outcome indicators are poorly defined. The outcome of Dynamic Infrared Thermography imaging of post-transposition changes of flap perfusion is reported.

Summary

Fasciocutaneous perforator flaps seem to have high survival rates and represent a feasible approach to post-traumatic reconstructions, especially in low-resource settings. A template for data gathering is recommended for higher accuracy in future comparative studies, and for scientific analysis of success and risk factors. New imaging techniques indicate a promising potential of micro-circular angiogenesis during the first two weeks after flap transpose.     

Limb lengthening over plate

Background:

The limb lengthening over plate eliminates the associated risk of infection with limb lengthening over intramedullary nail. We present our experience of limb lengthening in 15 patients with a plate fixed on the proximal segment, followed by corticotomy and application of external fixator.

Materials and Methods:

15 patients (7 females, 8 males) were included in this consecutive series. The average age was 18.1 years (range 8–35 years). Fifteen tibiae and one femur were lengthened in 15 patients. Lengthening was achieved at 1 mm/day followed by distal segment fixation with three or four screws on reaching the target length.

Results:

The preoperative target length was successfully achieved in all patients at a mean of 4.1 cm (range 1.8–6.5 cm). The mean duration of external fixation was 75.3 days (range 33–116 days) with the mean external fixation index at 19.2 days/cm (range 10.0–38.3 days/cm). One patient suffered deep infection up to the plate, three patients had mild procurvatum deformities, and one patient developed mild tendo achilles contracture.

Conclusion:

Lengthening over a plate allows early removal of external fixator and eliminates the risk of creating deep intramedullary infection as with lengthening over nail. Lengthening over plate is also applicable to children with open physis.     

A simple method for predicting survival of pedicled skin flaps before completely raising them

Background:

Pedicled skin and fasciocutaneous flaps are commonly used in plastic surgery. Once such a flap is completely raised on its pedicle it becomes defenceless against any possible necrosis.

Aim:

To use a simple method for raising such a flap in a manner that can predict the vascularity better, offering additional protection against necrosis.

Materials and Methods:

A total of 30 skin and fasciocutaneous flaps were raised in 27 patients. They were raised as bipedicle flaps; and the vascularity of the flap was tested by occluding the additional pedicle with a pedicle occlusion clamp. If the vascularity was found to be satisfactory the flap was primarily transferred; if found unsatisfactory it was either delayed or abandoned. The delayed flaps were again tested during transfer.

Results:

Nineteen (63.3%) flaps were primarily transferred, 11 (36.7%) flaps were delayed, and two (6.7%) delayed flaps displayed an unsatisfactory pattern during transfer. Twenty-two (73.3%) flaps fully survived and seven (23.3%) underwent partial thickness necrosis at the tip, which healed without any further surgical intervention, making 29 (96.7%) flaps clinically successful. There was major necrosis of one flap. All the flaps with a scar at the base survived.

Discussion:

The clinical success of 96.7% indicated a high-degree of predictability of flap survival through this method. Also, this method could safely assess the vascularity of flaps during primary transfer, during delayed transfer, and also those with a scar at the base.

Conclusions:

This technique is recommended in all major pedicled skin and fasciocutaneous flaps.KEY WORDS: Blood circulation, blood flow velocity, necrosis, skin transplantation, surgical flaps     

Keystone flaps in coloured skin: Flap technology for the masses?

Introduction:

Viscoelastic properties of skin in coloured ethnic groups are less favourable compared to Caucasians for executing Keystone flaps. Keystone flaps have so far been evaluated and reported only in Caucasians. The potential of Keystone flaps in a coloured ethnic group is yet unknown.

Aim:

This article reviews the experience to reconstruct skin defects presenting in a coloured ethnic group, by using Keystone flaps, with a review of existing literature.

Design:

Uncontrolled case series.

Materials and Methods:

This retrospective review involves 55 consecutive Keystone flaps used from 2009 to 2012, for skin defects in various locations. Patient demographic data, medical history, co-morbidity, surgical indication, defect features, complications, and clinical outcomes are evaluated and presented.

Results:

In this population group with Fitzpatrick type 4 and 5 skin, the average patient age was 35.73. Though 60% of flaps (33/55) in the series involved specific risk factors, only two flaps failed. Though seven flaps had complications, sound healing was achieved by suitable intervention giving a success rate of 96.36%. Skin grafts were needed in only four cases.

Conclusions:

Keystone flaps achieve primary wound healing for a wide spectrum of defects with an acceptable success rate in a coloured skin population with unfavorable biophysical properties. By avoiding conventional local flaps and at times even microsurgical flaps, good aesthetic outcome is achieved without additional skin grafts or extensive operative time. All advantages seen in previous studies were verified. These benefits can be most appreciated in coloured populations, with limited resources and higher proportion of younger patients and unfavorable defects.KEY WORDS: Skin ethnic variations, flap success rate, flap learning curve, flap resources, Keystone flap, skin extensibility     

Distally based cross-finger flaps for amputation stumps in avulsion amputations

Background:

Though advances in microsurgery have resulted in better survival rates of replants, replanting crushed and avulsed digits are difficult. If replantation is not possible these digits need local tissue cover to retain length.

Patients and Methods:

Twenty seven patients underwent distally based cross finger flaps for coverage of exposed vital structures over the amputation stumps.

Results:

All the flaps survived well. They provide good quality thin pliable tissue over the fingertips and help in achieving near normal range of movements in injured digits.

Conclusion:

Distally based cross finger flap gives tissues of right dimensions, at the most desired site, making reconstruction of these difficult problems quiet easy.KEY WORDS: Coverage of terminal finger defects, cross-finger flaps, distally based flaps     

A useful flap combination in wide and complex defect reconstruction of the medial canthal region: Glabellar rotation and nasolabial V-Y advancement flaps

BACKGROUND:

Reconstruction of medial canthal defects after tumour excision is difficult owing to the thin skin of the region and the concavity of the anatomical landmarks, which enclose complex structures such as the medial canthal ligament and the lacrimal system. Local reconstruction methods for this region include secondary healing, full-thickness skin grafts, and skin flaps from the frontal, transnasal, glabellar and upper eyelid regions.

OBJECTIVE:

To demonstrate a useful combination of two local flaps in wide defects of the medial canthal region.

METHODS:

Between 1998 and 2012, a combination of glabellar rotation and nasolabial V-Y advancement flaps were used in 11 patients with wide complex defects after excision, including periosteum, of invasive basal cell carcinoma.

RESULTS:

All patients were tumour free and underwent functional and aesthetic reconstruction of the medial canthal region. There were no major complications, and no relapses were observed.

CONCLUSION:

This technique achieves good match in colour and texture, and has satisfactory results both aesthetically and functionally. In addition, donor area morbidity is minimal and surgical technique is simple.     

Reconstruction of complex thoraco-abdominal defects with extended anterolateral thigh flap

Background:

The reconstruction of complex thoraco-abdominal defects following tumour ablative procedures has evolved over the years from the use of pedicle flaps to free flaps. The free extended anterolateral thigh flap is a good choice to cover large defects in one stage.

Materials and Methods:

From 2004 to 2009, five patients with complex defects of the thoracic and abdominal wall following tumour ablation were reconstructed in one stage and were studied. The commonest tumour was chondrosarcoma. The skeletal component was reconstructed with methylmethacrylate bone cement and polypropylene mesh and the soft tissue with free extended anterolateral thigh flap. The flaps were anastomosed with internal mammary vessels. The donor sites of the flaps were covered with split-skin graft.

Result:

All the flaps survived well. One flap required re-exploration for venous congestion and was successfully salvaged. Two flaps had post operative wound infection and were managed conservatively. All flap donor sites developed hyper-pigmentation, contour deformity and cobble stone appearance.

Conclusion:

Single-stage reconstruction of the complex defects of the thoraco-abdominal region is feasible with extended anterolateral thigh flap and can be adopted as the first procedure of choice.     

Thoracodorsal artery perforator fasciocutaneous flap: A versatile alternative for coverage of various soft tissue defects

Objective:

The thoracodorsal artery perforator (TDAP) flap has contributed to the efficient reconstruction of tissue defects that require a large amount of cutaneous tissue. The optimal reconstruction method should provide thin, and well-vascularized tissue with minimal donor-site morbidity. The indications for the use of this particular flap with other flaps are discussed in this article.

Materials and Methods:

Thirteen patients underwent soft tissue reconstruction using TDAP flaps between 2009 and 2011. Of those, there were four cases of antecubital burn contracture, three cases of axillary burn contracture, two cases of giant hair cell nevus of upper extremity, two cases of axillary reconstruction following severe recurrent hidradenitis, and two cases of crush injury. All patients were male and their ages ranged from 20 to 23 (average, 21 years). The mean follow-up period was 8 months (range, 4-22 months).

Results:

All reconstructive procedures were completed without any major complications. Minor complications related to transfered flaps were wound dehiscence in one case, transient venous congestion in two cases. Minor complication related to the donor site was seroma in one case. The success rate was 100%, with satisfactory cosmetic results.

Conclusions:

The TDAP flap is a safe and extremely versatile flap that offers significant advantages in acute and delayed reconstruction. Although the vascular anatomy may be variable, free and pedicled TDAP flap is a versatile alternative for soft tissue defects. It adapts very well to the soft tissue defects with acceptable donor site scar.KEY WORDS: Burn contracture, hidradenitis suppurativa, soft tissue defects, the thoracodorsal artery perforator, thoracodorsal artery perforator flap
