DIEP Flap for Head and Neck Reconstruction: An Underutilized Option!

Background The deep inferior epigastric artery perforator (DIEP) flap is a workhorse flap for breast reconstruction. Its use for head and neck (HN) reconstruction is rare. Abdomen provides a donor site abundant in skin and subcutaneous tissue, amenable to primary closure; sizeable, robust, and consistent perforators and a long, sizeable pedicle for comfortable microvascular anastomosis. Its offers all the donor variables needed for HN reconstruction in abundance. Methods It is a quasiexperimental design study. DIEP flap use for HN reconstruction in our series was opportunistic, that is, when donor site matched the defect. Cases that had very thick thighs and lesser bulk in abdomen and cases that had very thin thighs but much more bulk in abdomen were considered for reconstruction using DIEP flap. Results The DIEP flap was done in 11 cases for HN reconstruction. There were two re-explorations during postoperative period: one flap loss and another had partial necrosis. Conclusion Abdomen is an excellent donor site option for HN reconstruction in selected cases, especially when harvested as a perforator flap.

Management of Through-and-Through Oromandibular Defects after Segmental Mandibulectomy with Fibula Osteocutaneous Flap.

BACKGROUND: Oromandibular defects involving the external skin are a reconstructive challenge. This study aimed to evaluate the use of the fibula osteocutaneous free flap (FOCFF) for through-and-through oromandibular defects by comparing the surgical outcomes and complications of different techniques to close the external skin defect. METHODS: A retrospective analysis was conducted of patients who underwent reconstruction of through-and-through oromandibular defects after oncologic segmental mandibulectomy between January 2011 and December 2014. Five groups were analyzed according to the method of external skin coverage: primary closure, locoregional flaps, deepithelialized double-skin paddle FOCFF (deEpi-FOCFF), division of the skin paddle for double-skin paddle FOCFF (div-FOCFF), and a simultaneous second free flap. Intraoperative and postoperative outcomes along with complications were analyzed between groups. RESULTS: A total of 323 patients were included. The mean total defect area requiring a simultaneous second free flap was larger in comparison to other groups (p < 0.001). Reconstructions performed with div-FOCFF had a higher number of perforators per flap when compared with deEpi-FOCFF (p < 0.001). External defects closed with another free flap exhibited higher intraoperative time for the reconstructive segment in comparison to other groups (p < 0.05). The overall rate of complications was comparable between groups (24%, p = 0.129). CONCLUSION: The FFOCF is a reliable alternative to harvesting multiple simultaneous free flaps for through-and-through oromandibular defects. The authors recommend appropriate curation of the surgical plan based on individual patient characteristics and reconstructive requirements.

Free Thoracodorsal Artery Perforator Flap for Head and Neck Reconstruction: An Indian Experience.

Background We describe our experience with use of free thoracodorsal artery perforator (TDAP) flap for head and neck (H&N) cancer reconstruction, with respect to the patient and disease profile, suitable defect characteristics, the reconstructive technique, and complications. Methods Consecutive patients ( N = 26) undergoing free TDAP flap for H&N onco-reconstruction, in a single center, were included from January 2015 to December 2018 and the data were analyzed. Results Perforator(s) were reliably predicted preoperatively, using handheld Doppler. Lateral position was comfortable for the harvest. Twenty flaps were harvested on a single perforator, more commonly musculocutaneous ( n = 16). The thoracodorsal nerve and latissimus dorsi muscle could be preserved, completely in almost all cases. The skin paddle was horizontally ( n = 5) or vertically ( n = 21) oriented, both giving a satisfactory scar. The flap was used as a single island or two islands by de-epithelializing intervening skin. Pedicle length was sufficient in all cases. Four cases were explored for suspected venous insufficiency. Two had thrombosis, of which one was salvaged, while the other necrosed. One flap had minimal partial necrosis, which was managed with secondary suturing. The 5-year follow-up showed good oral competence, mouth opening, and cosmetic satisfaction among patients. Conclusion TDAP flap provides all the advantages of a perforator-based free flap and of back as a donor site with close color match to the face, relatively hairless, and thickness in between the thigh and the forearm. It can be a useful tool to provide an ideal functional and aesthetic outcome, with a hidden donor site and minimal donor site morbidity in selected cases.

Comparison of Functional Outcomes of Intestinal Flaps Vs Tubed Fasciocutaneous Flaps for Circumferential Pharyngoesophageal Defects-an Indian Perspective.

Pharyngolaryngoesophageal (PLO) reconstruction is a complex and technically demanding procedure. The reconstructive surgeon's concerns include avoiding fistula and stricture formation, as well as restoring normal speech and swallowing. A retrospective observational study with circumferential pharyngo-laryngo-oesophagal defects with aims and objectives of evaluation and comparison of the long-term functional outcomes like speech and swallowing along with the complications of fistula and stricture in two groups of JFF and FC flaps from the data is collected from electronic medical records of Tata Memorial Hospital, Mumbai, from January 2011 to May 2020. A total of 67 patients (52 JFF and 15 fasciocutaneous flaps) were operated on in last 9 years in our institute. The difference in fistula rates and stricture rates between the two groups was not significant (p= 0.98 and 0.947). The difference in 100% oral diet between the two groups was significant (p= 0.019). The difference in speech rehabilitation between the two groups was significant (p= 0.024). The intestinal tubes and fasciocutaneous tubes have comparable outcomes with regard to fistula and stricture formation. Speech outcomes in the form of the ability to have functional speech and voice quality were significantly better with skin-lined tubes. Swallowing outcomes were much better with intestinal tubes, along with early oral alimentation.

Utilizing the Retrograde Flow of Internal Mammary Vessels as a Donor Pedicle.

Introduction The aim of this study is to assess the results of retrograde flow of internal mammary artery and vein (IMA/V) as a donor vessel for free flap microvascular anastomosis (MVA). This need arises with bipedicle deep inferior epigastric perforator (DIEP) flaps, when all four zones with extra fat need to be harvested for unilateral breast reconstruction coupled with poor midline crossover of circulation naturally or because of midline scar. Large anterolateral thigh flaps for chest wall cover, with multiple perforators from separate pedicles, also need supercharging. This needs an additional source of donor vessels, antegrade IMA/V being the first one. Materials and Methods Retrospective study of microvascular breast reconstruction using retrograde internal mammary donor vessels. Results Out of 35 cases, 20 cases had distal IMA/V, with retrograde flow, as donor vessel for second set of arterial and venous anastomosis. In two cases, retrograde IMA/V was used for the solitary set of MVA. In remaining 13 cases, either retrograde IMA or V was utilized either as a principal or accessory donor. No flap was lost. Venous and arterial insufficiency happened in one case each, both were salvaged. Two cases developed partial necrosis, needing debridement and suturing. One case developed marginal necrosis. Only one case developed fat necrosis with superadded infection on follow-up. Conclusion Distal end of IMA and IMV on retrograde flow is safe for MVA as an additional or sole pedicle. It is convenient to use being in the same field. It enables preservation of other including thoracodorsal pedicle and latissimus dorsi flap for use in case of a complication or recurrence.

Outcome Analysis of Advanced Oral Cancers Requiring Large Composite Fibular Osteocutaneous Flap Reconstruction: Experience From a Tertiary Care Cancer Hospital.

BACKGROUND: Advanced oral cancer entailing extensive resection of large parts of the mucosa, bone, and skin require reconstructions with composite free flaps. Our aim was to analyze the outcomes of those oral squamous cell carcinomas requiring fibular osteocutaneous free flaps with large skin defects. METHODS: Perioperative course and histopathological and survival outcomes of 246 consecutive patients warranting composite fibular flaps from January 2010 to June 2015 at Tata Memorial Hospital, Mumbai, India, were retrospectively analyzed. RESULTS: Despite majority of T4 disease (88.2%) and stage IV disease (92%) patients, the 5-year overall survival was 52.1% and the 5-year recurrence-free survival was 48.6% with a median follow-up of 42 months with minimal complications. CONCLUSIONS: Reconstruction with composite fibular osteocutaneous flaps has comparable outcomes of survival with acceptable complications in mega oral squamous cell carcinomas requiring extensive resection.

Reduction Mammoplasty Approach to Oncoplasty-Zone-Wise Planning in Indian Patients.

Introduction This article is an attempt to formulate certain guidelines for planning of zone-wise reconstruction after breast conservation surgery. The planning involves applying reduction mammoplasty principles with certain modifications to address the defect. Patients and Methods This is a retrospective study of 61 patients with breast cancer who underwent breast conservation surgery and reconstruction of partial breast defects with oncoplastic techniques between January 2014 to March 2019. Patients having low tumor to breast ratio and thus good candidates for volume displacement techniques were included in the study. Results A total of 61 breast cancer cases were included; 22 cases were located in zone 1, nine in zone 2, seven in zone 3, three in zone 4, four in zone 5, one in zone 6, 12 in zone 7, two in zone 8, and three in zone 9. The most common pedicle design used was superomedial in 38 cases, followed by inferior in 19 and medial in 6 cases. Vertical short scar technique was used in 33 cases and Wise pattern skin incision in 30 cases. Follow-up period ranged from 4 months to 65 months, with a mean of 31 months. Four patients had partial skin necrosis, three had suture line dehiscence, two had wound infection, one had seroma, and eight patients had fat necrosis. All patients were satisfied with the cosmetic outcome. Conclusion Breast oncoplastic techniques are effective, reliable, oncologically safe, and conducted with minimal complications in patients with moderately large ptotic breasts, thereby making planning easier and more reproducible by following the reconstruction procedures described in the article. We believe that these techniques should be incorporated in the armamentarium of every plastic surgeon to manage the defects created after breast conservation surgery, in order to achieve the best cosmetic outcomes.

Chimeric ALT Plus TFL Perforator Flap for Breast Reconstruction Post Radical Mastectomy with Large Skin Defect.

A 17-year-old girl with large malignant phyllodes tumor of left breast underwent a radical mastectomy with large skin excision resulting in defect of 20 cm × 18 cm. Postoperative radiation therapy necessitated robust cover with flap. The challenge was compounded by her body habitus. Both abdomen and back were deficient as donor sites and a single-island anterolateral thigh (ALT) flap would need skin grafts, volume deficit withstanding. We harvested chimeric ALT plus tensor fascia lata (TFL) perforator free flap sparing all muscles and nerves. Microvascular anastomoses were done to the second internal mammary artery (IMA) perforator artery and vein. The donor site was closed primarily. The TFL flap territory recruited almost three times the volume of ALT territory and allowed us to create a matching breast mound in addition to covering the defect. She tolerated 40 Gy radiation well and doesn't desire further augmentation. Consistency of ALT and TFL perforators makes this a replicable procedure.

Plastic surgery practices amidst global COVID-19 pandemic: Indian consensus.

INTRODUCTION: The COVID-19 pandemic having spread globally has profound implications on medical and surgical care, which is given by the health care providers. At this time, though there are guidelines and recommendations for medical management of these patients, there is a lack of guidance on how a plastic surgeon should approach the COVID-19 suspect or infected patient who presents either in an elective or emergency setting. We aim to provide a consensus guideline based on the current recommendations of the Indian Council of Medical Research (ICMR) and the pooled experience of the major centers performing plastic and reconstructive surgery in India. METHODS: The current guidelines and recommendations on the COVID-19 pandemic were studied from both government and nongovernment sources including ICMR. The problems in the specialty of plastic surgery were categorized into four groups and for each group, separate and individual guidelines have been formulated. GUIDELINES: Consensus guidelines have been formulated for the specialty of Plastic and Reconstructive surgery. The patients requiring plastic surgery service have been categorized into four groups of acute, subacute, chronic, and late category. Acute cases are the ones who require intervention within 24-48 h. Subacute cases are the ones who require intervention in the next 3-10 days, while the chronic are the ones who need plastic surgery preferably within a month. The late category are the ones who need surgery within the next six months. This has been done based on the urgency and priority of surgical intervention titrated against the risks of operating and inadvertently acquiring the exposure of COVID-19-positive patients. CONCLUSION: Currently, in the wake of COVID-19 pandemic, there are no clear guidelines specific to the vast majority of patients who come for a plastic surgery intervention. This puts the patients at risk due to the impending plastic surgery problem while at the same time it poses a risk of exposure to COVID-19 for the surgical team. Consensus guidelines are presented, to steer the plastic surgeon in his work, in the wake of COVID-19 crisis. The guidelines are based on firm scientific evidence from the reputed research and regulatory bodies and have been made in consonance with plastic surgery experts around the country, so that these practices best suit the needs of the patients, while being mindful of resource limitations and infection risks. The approach of "delayed conservative treatment" works best in the present case scenario.

Thoracodorsal Artery Perforator and Superior Epigastric Artery Perforator Flaps for Volume Replacement Oncoplastic Breast Surgery.

Introduction Breast conservation therapy (BCT) and oncoplastic breast surgery (OBS) are now established modalities of treatment for breast cancer, with proven oncological safety. Traditionally, latissimus dorsi (LD) flaps have been the one-stop solution workhorse when volume replacement is needed. We present our experience with thoracodorsal artery perforator (TDAP) and superior epigastric artery perforator (SEAP) flaps. These flaps allow the preservation of muscle structure and function. Material and Methods Data were collected prospectively of patients in whom pedicled perforator flaps after BCT were used. A handheld 8-MHz audio Doppler was used to locate the perforators. TDAP flaps were used in four patients, whereas SEAP flaps were used in two patients. Skin paddle sizes ranged from 10 × 3 cm to 21 × 7 cm. Results TDAP flaps were used in four patients, whereas SEAP flaps were used in two patients All flaps survived. No flap had partial necrosis or fat necrosis. All donor sites were closed primarily and healed uneventfully, and none had a seroma requiring aspiration. Conclusion TDAP flaps can be selectively employed when the LD muscle function needs to be preserved. SEAP flaps can also be employed as a rare option in case of lower inner quadrant defects. Pedicled perforator flaps are a useful and reliable option for volume replacement OBS in select patients for reconstructing partial mastectomy defects.

Free fibula flap for lower limb salvage after tumour resection.

CONTEXT: Post-tumour resection lower limb salvage. AIM/INTRODUCTION: Resection of tumours of the femur and tibia around the knee and ankle joints results in large bony defects. Often arthrodesis is an alternative; in case, adequate functional motors cannot be preserved or due to economic constraints. Thus, in an immunocompromised patient, the vascularised fibula is the best form of reconstruction. The vascularised fibular flap (pedicled/free) can be used in combination with an allograft. We refer to such a combination reconstruction as 'allocombo'. The vascularised fibular graft hypertrophies in due course of time, and till that period, the allograft provides the required mechanical strength to allow early ambulation. SUBJECTS AND METHODS: A retrospective study of 24 cases of vascularised fibular graft for lower limb reconstruction was conducted from February 2003 to March 2014. The average defect size was 15.5 cm and the average length of fibula harvested was 24.35 cm. A total of 19 free fibular flaps and 5 pedicled fibula were done. Mean age was 26 years. Fibula was nestled in the allograft obtained from the tissue bank. RESULTS: The mean follow-up time was 52 months. Free flap success rate was 96%. Successful healing was achieved at 45 ends (97.8%). Radiological evidence of union at osteotomy sites occurred at an average of 6.8 months. Eight patients eventually succumbed to disease. At the final follow-up, the mean Musculoskeletal Tumour Society functional score of the evaluable patients was 26 (range 20-30). CONCLUSIONS: Pedicled fibula is a good option if the defect is within 14 cm of the knee joint at the femoral end. The vessels have to curve around the fibular head, thus its removal improves the reach of the pedicle. The flap is easy to harvest with predictable vascular anatomy and it can provide a large amount of vascularised bone and skin paddle. It results in early ambulation, rehabilitation and reduced morbidity. We realised that fixation is easier and chances of vascular injury are less in free as compared to pedicled fibula.

Tracheoesophageal puncture site closure with sternocleidomastoid musculocutaneous transposition flap.

INTRODUCTION: Tracheoesophageal voice prosthesis is highly effective in providing speech after total laryngectomy. Although it is a safe method, in certain cases dilatation or leakage occurs around the prosthesis that needs closure of tracheoesophageal fistula. Both non-surgical and surgical methods for closure have been described. Surgical methods are used when non-surgical methods fail. We present the use of the sternocleidomastoid musculocutaneous (SCMMC) transposition flap for the closure of tracheoesophageal fistula. MATERIALS AND METHODS: An incision is made at the mucocutaneous junction circumferentially around the tracheostoma. Tracheoesophageal space is dissected down to and beyond the fistula. The tracheoesophageal tract is divided. The oesophageal mucosa is closed with simple sutures. Then SCMMC transposition flap is raised and transposed to cover sutured oesophagus and the defect between the oesophagus and the trachea. RESULTS: This study was done prospectively over a period of 1 year from June 2012 to May 2013. This technique was used in patients with pliable neck skin. In nine patients, this procedure was done (inferior based flap in nine cases) and it was successful in eight patients. In one case, there was dehiscence at the leading edge of flap with oesophageal dehiscence, which required a second procedure. In two cases, there was marginal necrosis of flap, which healed without any intervention. Nine patients in this series were post-radiation. CONCLUSION: This method of closure is simple and effective for patients with pliable neck skin, who require permanent closure of the tracheoesophageal fistula.

Anterolateral Thigh Twin Free Flaps from a Single Donor Site-a Modification Based on the Oblique Branch of the Lateral Circumflex Femoral Artery.

The pedicle of the anterolateral thigh flap is formed by the descending branch of the lateral circumflex femoral artery. Recently, an oblique branch of lateral circumflex femoral artery was described by Wei et al., which can also be used as an alternative to the descending branch. We describe a case in which both the pedicles were used to create two free flaps (twin flaps) from the same thigh for post tumour reconstruction of breast.

Pedicled anterolateral thigh flap: a versatile flap for difficult regional soft tissue reconstruction.

Reconstruction of extensive oncosurgical defects of lower trunk, perineum and upper thigh, without the complexity of microsurgery, is a reconstructive challenge. Pedicled anterolateral thigh (ALT) flap offers many advantages over other regional flaps for this purpose, such as the large skin and soft tissue availability, the remarkable pedicle length and the reliability. However, there is paucity of literature describing the utility of pedicled ALT flaps for reconstruction of these difficult soft tissue defects. We present our experience of pedicled ALT flaps for various post oncosurgical defects. From January 2005 to August 2008, 85 pedicled ALT flaps were done in 78 patients for post oncological excision defects of lower trunk, groin, perineum, and upper thigh. Majority of patients were males, with locally advanced inguinal disease, underwent wide skin excision and en bloc nodal resection. Age group ranged from 22 to 81 years. The flap size ranged from 10 x 5 cm (50 cm) to 38 x 20 cm (760 cm). The length of the pedicle ranged from 8 to 14 cm. Satisfactory coverage was achieved in all patients, except one, where the flap had to be discarded due to absent artery in the vascular pedicle. Clinically, no functional deficit of knee extensor mechanism was seen in any of these patients during routine activities. Present study has shown the wide arc of rotation, large skin replacement potential, and reliability of pedicled ALT flap.

Novel flaps for head and neck reconstruction.

The head and neck region is important both functionally and aesthetically and its reconstruction poses a formidable challenge for plastic surgeons. A perforator flap is a flap of skin or subcutaneous tissue supplied by a vessel that perforates the deep fascia to gain access to flap. With improvement in our knowledge of the anatomy of blood supply to the skin, the perforator flaps have opened a whole new horizon for the plastic surgeon to choose flaps with better function and cosmesis. The locally available perforators enable flaps to be designed with excellent match in tissue characteristics. Perforator flaps limit donor site morbidity and as they are islanded complete insetting is possible in a single stage. The principal perforator flaps such as facial artery perforator flap, platysma flap and its variant the submental flap and supra-clavicular artery flap used in the head and neck reconstruction are discussed. The more commonly used flaps are the free radial artery forearm flap and the anterolateral thigh flap while the novel ones are the thoracodorsal artery perforator flap, medial sural artery perforator flap and the toe-web flap for commissure reconstruction. The indications, reach and drawbacks of these flaps have been discussed in this review.

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.

There is no donor side specificity of fibula free flap for complex oromandibular reconstruction.

BACKGROUND: The objective of this study was to prove that there is no significance to the donor side (right or left) of the free fibula osteocutaneous flap (FFOCF) in the reconstruction of complex oromandibular defects (COMD) and proper flap planning, designing and tailoring are important in reconstructing different types of COMD after tumour-ablative surgery. MATERIALS AND METHODS: Three hundred and eighty-six consecutive patients who where reconstructed with FFOCF for COMD from Jan 2005 to Dec 2009 over a period of 5 years were studied. Except in seven patients, all fibula flaps were harvested from the left leg as per convenience and to facilitate a simultaneous, two-team approach. Depending on the condition of the neck vessels, vascular anastomosis was performed on the right or the left side, irrespective of the side of the defect. RESULTS: Complete flap survival was seen in 334 patients (86.52%). Superficial skin necrosis was seen in 20 patients, and was managed conservatively (5.18%). Partial flap loss was seen in 20 patients (5.18%). There were 39 re-explorations. Complete flap loss was seen in 12 patients (3.10%). CONCLUSION: We found no significance in terms of the results as far as the side of flap donor leg or primary defect were concerned. Flap tailoring in terms of meeting the tissue requirement and vessel orientation were rather more important.

Successful management of free osteocutaneous fibula flap with anomalous vascularity of the skin paddle.

The free osteocutaneous fibula flap is an established method of reconstruction of maxillary and mandibular defects. The vascularity of the skeletal and the cutaneous components is provided by the peroneal artery via the nutrient artery and the septo- and musculocutaneous perforators. In rare situations, these perforators may arise from other major leg arteries. In such circumstances, the procedure has to be either abandoned or modified so that neither the vascularity of the flap nor the donor limb is compromised. We present a case of an anomalous musculocutaneous perforator, which originated from the proximal part of the posterior tibial artery, passed through the soleus muscle and supplied the skin paddle. The flap was elevated as a single composite unit and was managed by two separate vascular anastomosis at the recipient site, one for the peroneal vessels and the other for the anomalous perforator.
