ABSTRACT

BACKGROUND: Different fibula osteocutaneous free flap (FOCFF) configurations have been described with a double-skin paddle (DSP) to address composite through-and-through oromandibular defects: division of the skin paddle using different perforators (div-FOCFF) or a de-epithelialized DSP FOCFF (deEpi-FOCFF). This study aimed to compare the surgical outcomes using these two methods (deEpi-FOCFF/div-FOCFF). METHODS: Patients who underwent segmental mandibulectomy and reconstruction with a DSP FOCFF between 2011 and 2014 were included. We compared postoperative outcomes of patients undergoing reconstruction with deEpi-FOCFF versus div-FOCFF implementing propensity score matching. RESULTS: Of the 245 patients, 156 cases (78 pairs) were 1:1 matched. Demographic and oncologic variables were comparable between groups. The average age was 57.68 years. A higher number of perforators per flap was evident in the div-FOCFF group (p < 0.001). The deEpi-FOCFF group exhibited a higher total flap loss rate when compared to the div-FOCFF group (15 % versus 5 % p = 0.03). On multivariate analysis, number of perforators per flap (OR 0.31, p = 0.02), using the deEpi-FOCFF (OR 3.88, p = 0.03), and an increased reconstructive time (OR 1.01, p = 0.01) independently affected the likelihood of free flap failure. CONCLUSION: If the number and location of perforators are optimal, div-FOCFF improves reconstructive outcomes for composite oromandibular defects versus the deEpi-FOCFF.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

BACKGROUND: The thymus is a glandular organ that is essential for the formation of the adaptive immune system by educating developing T cells. The thymus is most active during childhood and involutes around the time of adolescence, resulting in a severe reduction or absence of naive T-cell output. The ability to generate a patient-derived human thymus would provide an attractive research platform and enable the development of novel cell therapies. OBJECTIVES: This study sought to systematically evaluate signaling pathways to develop a refined direct differentiation protocol that generates patient-derived thymic epithelial progenitor cells from multiple induced pluripotent stem cells (iPSCs) that can further differentiate into functional patient-derived thymic epithelial cells on transplantation into athymic nude mice. METHODS: Directed differentiation of iPSC generated TEPs that were transplanted into nude mice. Between 14 and 19 weeks posttransplantation, grafts were removed and analyzed by flow cytometry, quantitative PCR, bulk RNA sequencing, and single-cell RNA sequencing for markers of thymic-cell and T-cell development. RESULTS: A direct differentiation protocol that allows the generation of patient-derived thymic epithelial progenitor cells from multiple iPSC lines is described. On transplantation into athymic nude mice, patient-derived thymic epithelial progenitor cells further differentiate into functional patient-derived thymic epithelial cells that can facilitate the development of T cells. Single-cell RNA sequencing analysis of iPSC-derived grafts shows characteristic thymic subpopulations and patient-derived thymic epithelial cell populations that are indistinguishable from TECs present in primary neonatal thymus tissue. CONCLUSIONS: These findings provide important insights and resources for researchers focusing on human thymus biology.

ABSTRACT

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.

ABSTRACT

PURPOSE: Quality of life has become an integral aspect of the management of breast cancer. Many women still need to undergo a modified radical mastectomy (MRM). Factors affecting the choice a woman makes to undergo breast reconstruction (BR) are unclear and are hypothesized to be influenced by socioeconomic factors. We conducted a survey to evaluate the awareness and acceptability of BR among women with breast cancer at our institution. METHODS: A novel questionnaire was designed and served to 3 groups of women: planned for MRM, follow up (FU) post-MRM, and FU post breast-conserving surgery. RESULTS: Responses were analyzed from 492 women. Of these, 280 (56.91%) were planned for MRM and 212 (43.08%) women were on FU. Almost 45% women were older than 50 years of age, and literacy rate was 87.6%. More than 70% were homemakers and 15 women (3%) were unmarried. The aspects evaluating awareness of BR suggested that 251 (51.01%) women had knowledge about BR. Major source of information was the surgeon (45.81%) and media (32.87%). About 80% women on FU post-MRM did not want reconstruction, and 55% did not opt for BR as they had coped with the mastectomy and did not feel the need for BR. Only 6% cited family or financial reasons and 10% cited recurrence concerns. Among women planned for surgery, 65.71% had not considered BR. When questioned, 25 (12.88%) felt influenced by cost, 102 (52.58%) felt they did not need it, and 20 (10.31%) were worried it would affect treatment. CONCLUSION: Our study shows high awareness regarding BR, but only 27.89% women opt for BR independent of economic issues. We recommend all patients should be counseled about the reconstructive options when their MRM is planned.

ABSTRACT

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.

ABSTRACT

Existing anatomic factors play a significant role in affecting the possibility of dental rehabilitation in head and neck cancer patients undergoing free-fibular graft reconstruction. An observational, cross-sectional study was initiated to evaluate factors affecting dental rehabilitation following free-fibular graft jaw reconstruction in head and neck cancer patients.Patients who had undergone jaw reconstruction with free-fibular graft, requiring dental rehabilitation were recruited. Irradiated, reconstructed patients who had completed at least 1 year since the last dose of radiotherapy and nonradiated patients who had completed 6 months since reconstruction were recruited. Patients who had undergone soft-tissue reconstruction or free-fibular graft in non-condyle sparing resections were excluded. Patient's demographic data, disease and treatment-related data were obtained. An intra-oral examination was carried out to evaluate anatomic variables affecting dental rehabilitation. Descriptive statistical analyses were carried out to study demographic data. Logistic regression analysis was carried out using Pearson χ test and Fisher exact test. Estimates of regression coefficient and their standard errors with 95% confidence interval were calculated.Total of 138 patients were enrolled and considered for prosthetic rehabilitation. A review of the frequency-based data revealed that 30% (n = 41) patients were considered suitable for prosthetic rehabilitation. On multivariate logistic regression analysis, morbidity of radiotherapy (P = 0.01), interference to placement of implants by reconstruction plates and screws (P = 0.023), unfavorable diagnostic maxilla-mandibular relationship (P = 0.011), and obliterated vestibule (P = 0.001) were statistically established (P < 0.05) as the most significant reasons for not carrying out dental rehabilitation in patients who had undergone free-fibular graft reconstruction.

ABSTRACT

BACKGROUND: Survival studies may serve as benchmarks to develop cancer-related policies and estimate baseline survival rates in a given patient population. MATERIALS AND METHODS: We carried out a retrospective audit of cases managed in 2009 and now report the disease-free survival (DFS) in early breast cancer (EBC) and locally advanced breast cancer (LABC) in patients registered at a tertiary cancer center in India. RESULTS: The study included 2192 patients with breast cancer with ages ranging from 18 years to 94 years with a median of 50 years. Of these, 888 (40.5%) were EBCs Stage I and II, 833 (38%) were LABCs (Stage III), and 471 (21.5%) were de novo metastatic or relapsed cancers at presentation. The 5-year DFS in the women with EBC was 85.5% and in LABC, it was 67.7%, P < 0.001. The factors adversely affecting DFS in EBC were node metastasis (P < 0.001), higher metastatic nodes (P < 0.001), hormone receptor negativity (P = 0.001), and human epidermal growth factor receptor 2 (Her2neu) positivity (P = 0.033). In the multivariate Cox regression analysis in EBC, node-positive status (hazard ratio [HR] 2.28, 95% confidence interval [CI] 1.51-3.45, P < 0.001) and hormone receptor negative tumors (HR 1.96, 95% CI 1.30-2.94, P = 0.001) significantly affected DFS in EBC. The factors adversely affecting DFS in LABC in the univariate analysis were node metastasis (P < 0.001), increasing numbers of nodes (P < 0.001), presence of lymphovascular emboli (LVE) (P < 0.01), mastectomy (P < 0.001), and Her2neu positivity (P = 0.03). In the multivariate Cox regression analysis, node positivity (HR 2.96, 95% CI 2.04-4.29, P < 0.0001), presence of LVE (HR 1.47, 95% CI 1.06-2.04, P = 0.023), and mastectomy (HR 1.49, 95% CI 1.06-2.10, P = 0.023) adversely impacted DFS in LABC. CONCLUSIONS: The survival rates in this study are equal to the documented global rates; nodal disease burden emerged as the most important prognostic factor. In addition, in EBCs, a lack of hormone receptor expression and in LABC, Her2neu overexpression appear to worsen the outcome.

ABSTRACT

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.

ABSTRACT

OBJECTIVE: Theobjective of this study was to determine the indications, utility, advantages and surgical approach for the anteromedial thigh (AMT) flap. MATERIALS AND METHODS: We reviewed the records of the patients in whom the AMT flap was used for head and neck reconstruction. We use an anterior approach to harvest the anterolateral thigh (ALT) flap with a non-committal straight line incision. This preserves both ALT and AMT flap territories intact, and further decision is based on the intraoperative anatomy of perforator and pedicle. The ALT flap was usually used as the first choice when available and suitable. RESULTS: Free AMT skin flaps were harvested in 24 patients. All flaps were used for the head and neck reconstruction. Two flaps had marginal flap necrosis. One flap was lost due to venous thrombosis. DISCUSSION: The thigh is an excellent donor site as it has large available skin territory, expendable lateral circumflex femoral artery system and low donorsite morbidity. The ALT flap is the most commonly used flap for reconstruction of soft-tissue defects. However, it is characterised by variable vascular pedicle and perforator anatomy. The AMT flap is an excellent alternative when the ALT flap is not available due to variable perforator anatomy, injury to perforator, when an intermediate thickness is needed between distal and proximal thigh or a chimeric flap is needed. CONCLUSION: The AMT flap offers all the advantages of the ALT flap without increasing donor-site morbidity. The anterior non-committal approach keeps both the ALT and the AMT flap options viable.

ABSTRACT

Semantic relations have been studied for decades without yet reaching consensus on the set of these relations. However, biomedical language processing and ontologies rely on these relations, so it is important to be able to evaluate their suitability. In this paper we examine the role of inter-annotator agreement in choosing between competing proposals regarding the set of such relations. The experiments consisted of labeling the semantic relations between two elements of noun-noun compounds (e.g. cell migration). Two judges annotated a dataset of terms from the biomedical domain using two competing sets of relations and analyzed the inter-annotator agreement. With no training and little documentation, agreement on this task was fairly high and disagreements were consistent. The results support the utility of the relation-based approach to semantic representation.

ABSTRACT

BACKGROUND: Malignant salivary gland neoplasms are rare in children. The purpose of this study was to present our experience in the treatment of primary and recurrent salivary gland neoplasm and contribute to the fractional available data. METHODS: All patients <18 years, treated between June 2005 and April 2014 were included in this study. RESULTS: The parotid gland was the most common site for both primary (n = 18) and recurrent (n = 6) tumors and mucoepidermoid carcinoma, low or intermediate grade, main histological type. Surgical excision was performed in all patients, of which 13 patients received radiotherapy. Lymph node metastasis was present in 3 patients with primary tumor, which were assessed accurately on frozen section examination. Local recurrence occurred in 1 patient with primary tumor and all patients are alive. CONCLUSION: Surgery is the prime modality of treatment for malignant salivary gland neoplasm and is associated with excellent outcomes. The role of lymph node sampling and frozen section examination needs further evaluation in identifying lymph node metastasis. © 2015 Wiley Periodicals, Inc. Head Neck 38: 852-856, 2016.

ABSTRACT

Retalhos do músculo esternocleidomastoideo têm sido descritos na literatura para reconstrução dos defeitos da cavidade oral e tratamento da síndrome de Frey. Apesar de largamente estudado, esses retalhos não são utilizados com frequência para reconstruções na região de cabeça e pescoço devido limitações como tamanho reduzido, camadas inseguras, contorno da deformidade no pescoço e questões de segurança oncológica. Relata-se uso de perfurador baseado em transposição de retalho para defeito na região da posterior do pescoço, seguido por excisão de sarcoma de partes moles. Trata-se de alternativa válida para procedimentos de reconstrução como retalhos regionais de pedículo ou transferência de tecido livre em um grupo apropriado de pacientes.


Sternocleidomastoid musculocutaneous flaps have been described in the literature for reconstruction of oral cavity defects and treatment of Frey's syndrome. Although widely studied, it is not used routinely in head and neck reconstruction due to limitations like small size, unreliable skin paddle, contour deformity in the neck and the question of oncologic safety. We report use of perforator based musculocutaneous transposition flap for defect over nape of the neck, followed by excision of a soft tissue sarcoma. This constitutes a valid alternative to other reconstructive procedures like pedicled regional flaps or free tissue transfer in a suitable group of patients.

ABSTRACT

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.

ABSTRACT

Treatment of cancer is race against time! Following radical excision, breathing, speech, mastication and swallowing are hampered. Face is invariably involved. Beside functional normalcy, excellent cosmetic restoration is necessary for patient's life quality. Primary wound healing, quick resumption of adequate oral intake, prompt initiation of chemo-radiotherapy has direct bearing on cure. Primary reconstruction with pedicle or free flap is the choice of treatment in most protocols. Composite defects are requiring bone, muscle and skin restrict choice of donor site and may have shortfalls in aesthetic and functional requirements. To improve further newer, and newer modalities are being developed and used to give best aesthetic and functions. Navigation, use of three-dimensional imaging, stereo lithic model and custom made implant for reconstruction are recommended as they promise improvement in aesthetics. Robotic surgeries allow access for resection of tumours and reconstruction with free flap in deep oropharynx obviating need of doing mandibulotomy. Researchers in stem cell and tissue engineering are looking forward to regenerating tissues and avoid the need of autologous tissue flaps. Desired tissue combination across counter may be available in the future. Excellent immunosuppressant drugs have made it possible to reconstruct composite facial anatomical units with allotransplant in a single surgery, along sensory and motor recovery! Mythological heterogenic head transplant like clone Ganesha, will be a reality in the near future!!
