Reconstructive options after total laryngectomy with subtotal or circumferential hypopharyngectomy and cervical esophagectomy

Anterior mediastinal tracheostomy - a salvage procedure for tracheal necrosis after thyroidectomy for medullary thyroid cancer: a case-report

A 34-year-old male patient with recently diagnosed with medullary thyroid carcinoma underwent total thyroidectomy and radical neck dissection, requiring sharp dissection to separate the tumour from the trachea. He required post operative intubation due to bilateral vocal cord paralysis. He developed ischaemic necrosis of the upper two thirds of the trachea presenting with marked surgical emphysema and an infective wound. The wound was opened, drained and an endotracheal tube was negotiated through the sloughed trachea into the distal intrathoracic trachea with the cuff inflated just above the carina. This complication was managed with total pharyngo-laryngectomy, anterior deep mediastinal tracheostomy and construction of a neo-cervical oesophagus with a free lateral thigh fascio-cutaneous flap. This case highlights the potential complications of a procedure, perseverance, collaboration amongst various disciplines and teamwork for treating a rare and complex condition. The patient was discharged and has had an excellent recovery with good quality of life over two years of follow up.

Lateral hypopharyngectomy with laryngeal preservation reconstructed with inlay fascio-cutaneous free flaps: clinical and functional outcomes

Objective

Lateral hypopharyngectomy (LH) is one of the organ-preservation surgical strategies available for treatment of selected naïve early squamous cell carcinoma (SCC), as well as for rarer non-SCC tumours and persistent/recurrent/second primaries after chemoradiation of the lateral wall of the piriform sinus. Its reconstructive methods have been the subject of different approaches without a general consensus. The aim of the present study is to describe a retrospective series of LH reconstructed by inlay fascio-cutaneous free flaps, reporting on oncological and functional outcomes.

Methods

Patients who underwent LH at the Department of Otorhinolaryngology - Head and Neck Surgery of the University of Brescia, Italy, between 2017 and 2023 were retrospectively reviewed. Clinical history, tumour histotype, postoperative complications, functional, and oncological outcomes were collected.

Results

Seven patients (6 males, 1 female) were included. In all, 29% had a treatment-naïve neoplasm, while 71% had recurrent disease. The final histology included 3 SCC, 2 synovial sarcomas, one liposarcoma, and one single-site mucosal metastasis from cutaneous melanoma. Negative margins were achieved in 6 patients (86%). All patients had swallowing rehabilitation by speech therapists and were able to safely eat a free diet at discharge, except for one who needed a percutaneous endoscopic gastrostomy to support nutritional oral intake. After a mean follow-up of 34.3 months, all patients except one are alive.

Conclusions

Our study showed that, in selected cases, it is possible to radically remove lateral hypopharyngeal tumours with laryngeal preservation and free flaps inlay reconstruction, with a low rate of complications and acceptable functional and oncological results.

Edge De-epithelialization for Reducing Pharyngocutaneous Fistula in Patch Free Flap Reconstructions for Salvage Total Laryngectomy Defects: A Case-Control Study

BACKGROUND

The leakage of saliva through the deep neck region from a pharyngocutaneous fistula could cause devastating complications, including vascular ruptures leading to mortality. While a partial pharyngoesophageal defect is created after total laryngectomy, a patch pattern of hypopharyngeal reconstruction is required, for which a fasciocutaneous free flap is usually applied. If radiotherapy fails to cure pharyngeal cancer, salvage total laryngectomy (STL) is needed. However, postradiation tissues tend not to heal well, and the incidence of pharyngocutaneous fistula therefore increases. We proposed an edge-epithelialization method to address this problem and conducted a retrospective study for comparison.

METHODS

The inclusion criteria were patients with head and neck cancer who underwent total laryngectomy that immediately required patch free flap reconstruction at a single medical center (January 2012-December 2021). Receipt of presurgical radiotherapy, hospitalization duration, and the presence of postoperative complications were recorded.

RESULTS

The included patients were separated into two groups: Group A (edge de-epithelialization not adopted) (n = 79) and Group B (edge de-epithelialization adopted) (n = 51). Forty-four and twenty-two patients in Groups A and Group B, respectively, received preoperative radiotherapies and simultaneous STL and fasciocutaneous free flap reconstructions. The incidence of pharyngocutaneous fistula was significantly lower in Group B (p = 0.0145). This phenomenon was the same for patients who underwent preoperative radiotherapy only (p = 0.0470) but not for patients who did not receive preoperative radiotherapy (p = 0.2363).

CONCLUSIONS

Edge de-epithelialization is an effective method for reducing pharyngocutaneous fistula formation in patch free flap reconstructions after STLs.

Temporal Variability in the Incidence and Risk Factors for Pharyngocutaneous Fistula Development after Total Laryngectomy

Background: This study aimed to analyse the variability in the incidence of the pharyngocutaneous fistula (PCF), the most common complication following a total laryngectomy (TLE), and to identify the underlying causes for fluctuations in incidence rates. Methods: In the retrospective study, the annual PCF incidence data and comprehensive clinicopathologic data from 540 patients who underwent TLE between January 2004 and December 2022 were reviewed. Distinct peri ods of both high and low PCF incidence were identified. Within these periods, patients were categorized into groups with PCF (study groups) and without it (control groups). These groups were statistically compared based on potential risk factors for PCF development. The high-incidence periods were specially analysed for recurring risk factors and the corresponding corrective measures were reviewed. Results: The analysis revealed four high-incidence periods with an overall PCF incidence of 37.61%, along with three low-incidence periods in between with an overall incidence of 19.38%. Surgical wound infection (SWI) and a history of head and neck cancer alongside their related treatments were repeatedly identified as independent risk factors during high-incidence periods, with SWI being the most consistent predictor of PCF development. Conclusions: Continuous monitoring of PCF incidence is crucial, as it allows for the identification of emerging risk factors and the immediate implementation of corrective measures to mitigate these newly identified risk factors.

Diet Outcome in Patients With Hypopharyngeal Defects Repaired With Different Reconstruction Flaps: A Comparative Study

OBJECTIVES

To assess potential risk factors influencing diet outcomes after reconstruction of subtotal hypopharyngeal defects using free patch- or tube-shaped anterolateral thigh (ALT) fasciocutaneous flaps.

STUDY DESIGN

Retrospective cohort study.

SETTING

First-level referral hospital.

METHODS

Between January 2011 and December 2020, we studied hypopharyngeal cancer patients who underwent the reconstruction of hypopharyngeal defects using free patch- or tube-shaped ALT fasciocutaneous flaps. The choice between patch- or tube-shaped ALT flaps depended on the defect's nature, favoring patch-shaped for subtotal defects and tube-shaped for circumferential defects. A restricted diet was characterized by a history of enterostomy or endoscopic esophageal dilation treatment postreconstruction. We analyzed patients with restricted diets at 1- and 3-year follow-up visits.

RESULTS

Ninety-eight patients were enrolled; 39 patch-shaped flaps, and 59 tube-shaped flaps. No significances were noted in demographics, postoperative radiotherapy (RT) or chemotherapy, rates of free flap reoperation/salvage, or complications. However, a significant difference emerged in diet outcomes at the 1-year follow-up (P = .005). The rate of a restricted diet was 6.08 times higher in patients with tube-shaped flaps compared to patch-shaped flaps (95% confidence interval [CI]: 1.95-18.94). Stratifying based on postoperative RT revealed a 5.47 times higher rate of a restricted diet in tube-shaped flap recipients compared to patch-shaped flap recipients (95% CI: 1.44-20.48). No significances were observed in 5-year survival rates.

CONCLUSION

Concerning postoperative RT, patch-shaped flaps exhibited a lower incidence of a restricted diet compared to tube-shaped flaps. Preservation of the posterior mucosa may play a crucial role in preventing RT-induced esophageal stricture.

Surgical Intervention to Treat Pharyngolaryngeal Stenosis Caused by Behcet's Disease

We aimed to summarize the surgical treatment for pharyngolaryngeal stenosis and discuss prognosis in patients with Behcet's disease. Six cases of pharyngolaryngeal stenosis caused by Behcet's disease were analyzed retrospectively. All underwent surgical treatment for pharyngolaryngeal stenosis after systematic medical treatment. The follow-up time for the 6 patients was between 1 and 12 years. Four of the 6 patients underwent adhesiolysis as their first procedure. Two of these 4 experienced recurrence of stenosis within 6 months and underwent flap repair as their second procedure. The remaining two patients underwent flap reconstruction as their first procedure and maintained good swallowing function. Three of the 6 patients underwent preoperative tracheotomy because of dyspnea. Tracheal decannulation was successful in all patients. None of the patients experienced recurrence after their final surgical procedure and all recovered to a near-normal condition. Pharyngolaryngeal stenosis caused by Behcet's disease is a rare but severe complication; surgical intervention should be considered in patients with dysphagia after systematic medical treatment.

Infrahyoid Myocutaneous Flaps with Common Wall of Hypopharyngeal and Esophageal Serosas for Voice Rehabilitation After Total Laryngectomy

IMPORTANCE

Patients who undergo total laryngectomy lose the voice function permanently. It is important to reconstruct the voice function of the patients after total laryngectomy.

OBJECTIVE

To explore a novel method for voice rehabilitation by suturing infrahyoid myocutaneous flaps to the hypopharyngeal and esophageal serosas after total laryngectomy and investigate its clinical efficacy.

DESIGN

Clinical study (retrospective study).

PARTICIPANTS

Twenty patients with advanced laryngocarcinoma who underwent total laryngectomy.

METHODS

Following total laryngectomy, the pharyngeal cavity was formed via layer-by-layer suturing, and the infrahyoid myocutaneous flap was sutured to the common wall of hypopharyngeal and esophageal serosas to create a voice tube.

RESULTS

Flap failure was not observed in any patient. All patients were able to vocalize after surgery. The voice after the reconstruction was smooth and natural. However, 3 patients were unable to vocalize gradually. Two patients experienced aspiration, requiring the removal of the voice tube, while 3 patients exhibited mild aspiration, which could be overcome by pressing the larynx on the voice tube surface.

CONCLUSIONS

Using infrahyoid myocutaneous flaps with the common wall of the hypopharyngeal and esophageal serosas was effective in rehabilitating voice after total laryngectomy. Future clinical studies are necessary to validate the effectiveness of this technology for voice rehabilitation.

Comparison of outcomes between circumferential and near-circumferential pharyngoesophageal reconstruction using anterolateral thigh flap

A leftover narrow strip of the posterior pharyngeal wall may form after laryngopharyngectomy, and whether to retain it during reconstruction remains debated owing to the differing views on the incidence of leakage and strictures. This study aimed to ascertain whether this remnant posterior pharyngeal wall is advantageous or disadvantageous to surgeons performing pharyngoesophageal reconstruction. We reviewed the data of patients with circumferential or near-circumferential pharyngoesophageal defects following oncological laryngopharyngectomy who underwent reconstructive surgery utilizing the anterolateral thigh flap. They were then categorized into two groups: circumferential and near-circumferential. Thereafter, their demographics, operative findings, and postoperative outcomes were compared. Forty patients (20 in each group) with an average age of 57.2 ± 6.7 years (range: 40-72) were enrolled in the study. All flaps except one survived. During a mean follow-up of 41.1 ± 24.6 (range: 6-95) months, the stricture rate was significantly lower in the near-circumferential group (one vs. nine [from 17 patients who had resumed oral intake postoperatively] patients in the near-circumferential and circumferential groups, respectively, p = 0.002). Oral intake was viable in all patients with near-circumferential defects but only in 11 patients with circumferential defects (p = 0.003). The near-circumferential group had fewer strictures and better tolerance of oral nutrition, supporting the incorporation of the residual posterior pharyngeal wall via near-circumferential reconstruction instead of discarding it to facilitate circumferential reconstruction.

Pharyngeal Reconstruction Methods to Reduce the Risk of Pharyngocutaneous Fistula After Primary Total Laryngectomy: A Scoping Review

INTRODUCTION

The most common early postoperative complication after total laryngectomy (TL) is pharyngocutaneous fistula (PCF). Rates of PCF are higher in patients who undergo salvage TL compared with primary TL. Published meta-analyses include heterogeneous studies making the conclusions difficult to interpret. The objectives of this scoping review were to explore the reconstructive techniques potentially available for primary TL and to clarify which could be the best technique for each clinical scenario.

METHODS

A list of available reconstructive techniques for primary TL was built and the potential comparisons between techniques were identified. A PubMed literature search was performed from inception to August 2022. Only case-control, comparative cohort, or randomized controlled trial (RCT) studies were included.

RESULTS

A meta-analysis of seven original studies showed a PCF risk difference (RD) of 14% (95% CI 8-20%) favoring stapler closure over manual suture. In a meta-analysis of 12 studies, we could not find statistically significant differences in PCF risk between primary vertical suture and T-shaped suture. Evidence for other pharyngeal closure alternatives is scarce.

CONCLUSION

We could not identify differences in the rate of PCF between continuous and T-shape suture configuration. Stapler closure seems to be followed by a lower rate of PCF than manual suture in those patients that are good candidates for this technique.

Comparison of the outcomes of anterolateral thigh flap and peroneal flap in total laryngectomy reconstruction

Background

We usually use an ALT or peroneal flap in total laryngectomy reconstruction, depending on the surgeons' preference. No direct comparison of the outcomes of the ALT flap and peroneal flap exists.

Methods

From 2014 to 2022, we reviewed patients who had total laryngectomy and were reconstructed with an ALT flap and peroneal flap. Patient characteristics and surgical outcomes were collected and compared.

Results

The peroneal group had a significantly higher risk of neopharynx leakage (40% vs. 13.2%, p = .020) and late pharyngocutaneous fistula formation (30% vs. 5.3%, p = .009) than the ALT group. Peroneal flap was found to be the only independent risk factor for neopharynx leakage (p = .025, odds ratio [OR] = 5.5) and late pharyngocutaneous fistula formation (p = .02, OR = 7.7) in multivariate logistic regression.

Conclusion

In the reconstruction of total laryngectomy, the ALT flap is preferable over the peroneal flap.

Neopharyngeal Stricture following Laryngectomy

Stricture formation is a serious complication following pharyngeal reconstruction. These strictures can be life-threatening and can severely impact quality of life. In this article, the existing literature on surgical risk factors linked to neopharyngeal stricture formation is reviewed. Intraoperative preventative measures reconstructive surgeons should consider are also discussed. Finally, this article will describe the evaluation and management of pharyngoesophageal strictures, including the challenges and options when dealing with refractory strictures.

Successful cervicothoracic esophageal stricture treatment with partial sternectomy and a pedicled TAAP flap: A case report

Postoperative benign esophageal anastomotic leakage and stenosis are common complications after esophagectomy. Treatment options for anastomosis stenosis include endoscopic mechanical dilation, dilation-combined steroid injection, incisional therapy, stent placement, and self-bougienage. However, long-segmental cervicothoracic esophageal stenosis and cutaneous fistula are always refractory to conservative treatments and are clinically challenging. When lesions extend well below the thoracic inlet, transthoracic esophagectomy and alimentary canal reconstruction seem to be the common choice but are susceptible to perioperative mortality and donor-site sequelae, especially for patients with poor health conditions. In this report, we present a novel surgical approach for cervicothoracic esophageal stenosis and fistula via partial sternectomy and reconstruction with a pedicled thoracoacromial artery perforator flap. No recurrence or complications occurred throughout 3 months of follow-up. This case study adds new perspectives to the treatment of anastomotic stenosis.

Perforator‐based chimeric anterolateral thigh flap U‐shaped insetting for total pharyngoesophageal reconstruction: Surgical technique and functional outcomes

BACKGROUND

Pharyngoesophageal reconstruction with the tubed anterolateral thigh (ALT) flap is burdened by possible strictures and pharyngocutaneous fistulae (PCF). We present our experience with the U-shaped insetting of perforator-based chimeric ALT flap focusing on surgical technique, complications and functional outcomes.

METHODS

We retrospectively included 10 patients with a total circumferential defect of the hypopharynx undergoing reconstruction with ALT flap. A perforator-based chimeric ALT flap with two independent skin paddles was harvested: the trapezoid paddle with the greater base cranially and the height oriented vertically was used for pharyngoesophageal reconstruction while the second paddle was exteriorized and used for flap monitoring and reducing tension on skin closure. Mean age was 56.4 years. Eight patients were affected by squamous cell carcinoma. Modified barium swallow radiogram and fiberoptic laryngoscopy were performed to assess strictures and PCFs. Swallowing and speech outcomes were evaluated through the Deglutition Handicap Index (DHI), M.D. Anderson Dysphagia Inventory (MDADI) and Voice Handicap Index (VHI) questionnaires.

RESULTS

Mean flap dimension was 7.9 × 6 × 9.2 cm. Mean ischemia time was 58.2 min (range 42-80). No flap loss nor flap-related complications were reported. Two PCFs were observed. Fiberoptic laryngoscopy documented a complete integration of the flap with no strictures or stenosis. Mean follow-up was 13.6 months (range 1-45 months). Mean DHI score was 33.8, mean MDADI score was 62.5, mean VHI score was 32.2.

CONCLUSIONS

The ALT flap U-shaped insetting is a reliable option for pharyngoesophageal reconstruction yielding a high success rate, low number of strictures and fistulae and good swallowing and voice outcomes.

Versatility of the subscapular system of flaps in head and neck oncologic reconstruction

PURPOSE OF REVIEW

This review analyzes the different ways of applying the subscapular system of flaps (SSSF) as a convenient and versatile solution for a large variety of head and neck oncologic defects.

RECENT FINDINGS

The ventral approach permits safe and efficient harvest of various chimeric SSSF in a supine position, thus allowing simultaneous flap preparation and tumor ablation. Conformational studies have revealed how similar the tip of the scapula is to the hard palate in terms of dimensions, shape, and conformation. This has led to favor horizontal placement of the scapular tip for palate reconstruction in most instances, addressing the vertical extension of the postmaxillectomy defect using denuded bony grafts surrounded by well vascularized chimeric muscular components.

SUMMARY

The SSSF possesses an unparalleled versatility to efficiently address small-medium sized soft tissue defects up to vast and complex composite resections. The chimeric components of these flaps benefit from a considerable independency provided by the length of the named arteries arising from the thoracodorsal pedicle, offering a high degree of freedom to accomplish the required in-setting. This reconstructive option should be implemented in every head and neck surgical team and offered to suitable patients.

Postoperative Complications and Swallowing Function after Jejunal and Skin Flap Reconstruction for Hypopharyngeal Carcinoma-A Multicenter Retrospective Study

This study compared the incidence of perioperative complications and swallowing function between free jejunal flap reconstruction and cutaneous free tissue flap construction. We included 223 patients who underwent hypopharyngeal reconstruction using free flap. At discharge, +the free jejunal flap was associated with a Functional Oral Intake Scale (FOIS) score of 1-6 in 132 cases (70%) and a score of 7 in 56 cases (30%). Regarding the cutaneous free tissue flaps, FOIS scores of 1-6 were observed in 18 cases (51%), and a score of 7 was noted in 17 cases (49%). Donor site complications occurred in 12% of the patients who underwent free jejunal flap procedures and in none of the patients who underwent cutaneous free tissue flap procedures. We found that the free jejunal flap had a regular dietary intake rate in 56 patients (30%), whereas cutaneous free tissue flaps had a regular dietary intake rate in 17 patients (49%). Cutaneous free tissue flaps had a significantly higher regular dietary intake rate at discharge and a significantly lower incidence of donor site complications than free jejunal flaps. In conclusion, free-flap reconstruction may be a better method than free jejunal flap reconstruction for the treatment of hypopharyngeal cancer.

Adipofascial anterolateral thigh free flap in hypopharyngeal and oropharyngeal reconstruction

BACKGROUND

The anterolateral thigh (ALT) flap is a popular choice for head and neck reconstruction surgery, but its ungainly thickness makes it of limited value in some intracavitary reconstructions. The ALT adipofascial flap is an improved flap without skin or muscle. Here, we seek to further illustrate the ALT adipofascial flap as an alternate method of hypopharyngeal and oropharyngeal reconstruction in head and neck.

METHODS

A retrospective review of 9 patients (7 men, 2 women) ranging from 28 to 67 years (mean age, 53.1 years) who underwent reconstruction with the ALT adipofascial flap after hypopharyngeal carcinoma (4 patients) or oropharyngeal carcinoma (5 patients) resections from August 2018 to December 2019 was performed. Surgical outcomes and functional resoration were assessed.

RESULTS

The size of the flaps ranged from 6 × 4 cm² to 6 × 12 cm² . The average flap thickness was 0.14 cm (range, 0.1-0.2 cm) and the average pedicle length was 9.8 cm (range, 7-12 cm). The postoperative course was uneventful in eight patients. Reconstruction was successful in all cases during 7-23 months of follow-up (mean time, 14.3 months). All patients resumed oral feeding for 2-8 weeks (mean time, 4.9 weeks) and the tracheal cannula was successfully removed 0.5-4 months postsurgery (mean time, 2.4 months).

CONCLUSION

The ALT adipofascial flap is a viable choice for hypopharyngeal and oropharyngeal reconstructions and is thinner than the ALT flap. It could be harvested as a single-pedicled double-island flap for complex defect reconstruction.

Diagnosis and management of pharyngoesophageal stenosis: A comprehensive approach to prophylactic, endoscopic, and reconstructive treatment options

BACKGROUND

Pharyngoesophageal stenosis (PES) is a serious complication that substantially impacts functional outcomes and quality of life (QOL) for up to a third of head and neck cancer patients who undergo radiotherapy. Dysphagia is often multifactorial in nature and is a devastating complication of treatment that impacts patients' QOL, general health and overall wellbeing. The authors detail the clinical presentation, risk factors, imaging characteristics, preventive measures, and multimodality treatment options for PES.

METHODS

The authors present a comprehensive management algorithm for PES, including treatment by dilation, stenting, spray cryotherapy and dilation, and reconstructive treatment options utilizing different pedicled and free flaps.

RESULTS

The authors advocate for a thorough assessment of the extent and degree of pharyngoesophageal involvement of PES to determine the optimal management strategy.

CONCLUSIONS

The development of post treatment dysphagia requires appropriate imaging and biopsy, when indicated, to rule out the presence of persistent/recurrent cancer. Multidisciplinary management by a team of physicians well-versed in the range of diagnostic and therapeutic interventions available for PES is critical to its successful management.

Jejunal and ileocolic free flaps for digestive tract reconstruction following pharyngo-laryngo-oesophagectomy - 30 years of single-centre experience

Introduction

Hypopharyngeal cancer accounts for 3–5% of all squamous-cell carcinoma (SCC) of the head and neck and has one of the worst prognoses. The aim of the study was to evaluate oncologic and functional treatment outcomes in patients with T3-T4a squamous cell hypopharyngeal and laryngeal cancer.

Material and methods

Retrospective analysis of the material from one treatment site included 90 patients (81 male, 9 female) who had undergone surgery between 1986 and 2010. Their mean age was 55.06 years (range 36–75).

Results

TNM (T – tumour, N – node, M – metastasis) staging assessment was feasible in 70 treatment-naïve patients (77.78%): 57 (63.33%) were classified to stage T4a, and 13 were classified to T3 (14.44%). Cervical lymphadenopathy was observed in 53 (63.3%) patients; in 44 patients (48.89%) postoperative histopathology confirmed metastatic disease. G2 or G3 SCC was detected in 80% of patients. All patients underwent laryngopharyngoesophagectomy (LPE). Digestive tract reconstruction was performed using one of two methods: jejunal autograft (JA) in 79 patients (87.78 %) – Group A or ileocolic autograft (IA) in 11 patients (12.22%) – Group B. Comparative statistical analysis of both groups showed statistically significant differences only for substitute speech production. The mean survival time of patients from both groups was 2.21 years after reconstruction surgery.

Conclusions

JA or IA for digestive tract reconstruction in patients after LPE are burdened with high risk of complications but offer patients the chance of a normal oral diet shortly after surgery. Ileocolic autograft enables rapid production of substitute speech.

The ideal flap for reconstruction of circumferential pharyngeal defects: A systematic review and meta-analysis of surgical outcomes

BACKGROUND

There is a lack of consensus regarding the superiority of the common free flaps for the reconstruction of circumferential pharyngeal defects.

METHODS

A systematic literature search was conducted to identify studies reporting the complications of circumferential pharyngeal reconstruction between 2005 and 2020. Anterolateral thigh free flaps (ALTFF), jejunal free flaps (JFF), and radial forearm free flaps (RFFF) were compared. Various complications were compared by meta-analysis. Primary endpoints were fistula and stricture rates.

RESULTS

Forty studies were included (2230 patients). Stricture rate was similarly low with tubed ALTFF (13.3%, n = 36/270) and JFF (13.2%, n = 176/1334). Fistula rate was the lowest with JFF (9.2%, n = 58/634). ALTFF was associated with the lowest rates of partial and complete flap failure (3.8%, n = 6/157, and 2.8%, n = 5/178), infection (2.8%, n = 3/106), donor site morbidity (3.9%, n = 5/130), and mortality (0%, n = 0/101) within 30 days. A meta-analysis demonstrated that there was no statistically significant difference in stricture and fistula rates between ALTFF and JFF. Moreover, JFF was associated with a significantly lower fistula rate than that of RFFF (p < 0.001). ALTFF was associated with a significantly lower infection rate than that of JFF (p = 0.013).

CONCLUSIONS

The data suggest the use of ALTFF for circumferential pharyngeal defects. In the absence of randomized, prospective data, the authors hope the results presented can be used as an evidence-based reference.

Peroneal flap: How to harvest and clinical appraisal for head and neck reconstruction

BACKGROUND

A peroneal flap, the boneless version of fibula flap, is considered as the equivalent of radial forearm flap of the lower leg. Because it is thinner than an anterolateral thigh (ALT) flap, the use of a peroneal flap is a viable option for the repair of soft tissue defects when a thin flap could bring about better functional and cosmetic outcomes. In this article, we describe the details of peroneal flap harvest and present our experience with the use of peroneal flaps for head and neck reconstruction.

MATERIALS AND METHODS

Between 1996 and 2017, a total of 265 peroneal flaps were used to reconstruct a variety of head and neck defects. With the same vascular anatomy and slight modifications to the harvesting technique of a fibula flap, a peroneal flap can be harvested within 1-2 h. All medical records were retrospectively reviewed.

RESULTS

A peroneal flap can be harvested as different types of chimeric flaps to fit a variety of head and neck defects. The peroneal flap failure rate was 3.4% and the postoperative complication rate was 12.8%.

CONCLUSION

A peroneal flap might be an alternative option for the reconstruction of head and neck defects.

Montgomery Salivary Bypass Tube in Head and Neck Cancer: The Experience of Our Otolaryngology Clinic

INTRODUCTION

One of the most common complications in the immediate and late postoperative period following total laryngectomy or pharyngolaryngectomy is pharyngocutaneous fistulae (PCF) formation and pharyngoesophageal stenosis (PES), causing significant mortality and morbidity. Since 1978, Montgomery salivary bypass tube (MSBT) has been used to reduce the incidence of PCF and PES. The aim of this retrospective study was to analyze the outcomes of using MSBT both as a tool to prevent PCF and PES and to treat these complications in the postoperative period.

METHODS

Between January 2013 and December 2019, we inserted 109 MSBT in 87 patients with laryngeal/hypopharyngeal cancer treated in the Unit of Otolaryngology of our University Hospital.

RESULTS

Sixty (86.9%) patients healed from complications with primary and secondary placement of MSBT. Seven patients presented a persistence of PCF and 2 presented a recurrence of PES. Secondary placement of MSBT allowed treating successfully 15 (83%) of 18 patients. Only 3 of them presented a PCF at the end of the follow-up period.

CONCLUSION

According to our experience, the MSBT is an affordable, easy to apply and well-tolerated tool. Although it is generally used for PCF treatment, it can also be used intraoperatively for PCF and PES prevention.

Pectoralis Major Onlay vs Interpositional Reconstruction Fistulation After Salvage Total Laryngectomy: Systematic Review and Meta-analysis

OBJECTIVE

To evaluate the difference in pharygocutaneous fistula (PCF) development between pectoralis major flap onlay and interpositional reconstructions after salvage total laryngectomy (STL).

DATA SOURCES

Medline, Cochrane, Embase, Web of Science, CINAHL, and ClinicalTrials.gov.

REVIEW METHODS

A systematic review was performed during January 2020. English articles were included that described minor and major PCF rates after STL reconstructed with pectoralis major onlay or interposition. PCFs were classified as major when conservative therapy was unsuccessful and/or revision surgery was needed. Articles describing total laryngopharyngectomies were excluded. Meta-analyses of the resulting data were performed.

RESULTS

Twenty-four articles met final criteria amassing 1304 patients. Three articles compared onlay with interposition, and 18 compared onlay with primary closure. Pectoralis interposition demonstrated elevated odds ratio (OR) of PCF formation as compared with onlay (OR, 2.34; P < .001). Onlay reconstruction reduced overall (OR, 0.32; P < .001) and major (OR, 0.21; P < .001) PCF development as compared with primary pharyngeal closure alone. Data were insufficient to compare interposition against primary closure.

CONCLUSIONS

This research shows evidence that pectoralis onlay after STL diminishes the odds of total and major PCF development. Pectoralis interposition reconstruction showed elevated odds of PCF formation as compared with pectoralis onlay.

Speech Performance after Anterolateral Thigh Phonatory Tube Reconstruction for Total Laryngectomy

OBJECTIVE

Traditionally, after total laryngopharyngectomy (TLP), patients cannot speak without a prosthesis or an artificial larynx. In Taiwan, most patients use a commercialized pneumatic laryngeal device (PLD). Phonatory tube reconstruction with the anterolateral thigh (ALT) flap is a novel, modified version of synchronous digestive and phonatory reconstruction involving a free muscular cutaneous flap. This study reviewed and compared speech performance between patients who underwent novel flap reconstruction and conventional PLD users.

METHOD

We retrospectively reviewed patients with laryngeal or hypopharyngeal cancer who underwent TLP from August 2017 to September 2019. The voice handicap index (VHI), speech intelligibility, acoustic and aerodynamic analysis results, and speech range profile (SRP) were compared between patients who underwent ALT phonatory tube reconstruction (ALT group) and those using PLDs (PLD group).

RESULTS

Twenty patients were included; 13 patients were included in the ALT group, and 7 patients were included in the PLD group. Compared to the PLD group, the ALT group had a better fundamental frequency range (P < .001) and semitone range (P < .001) during speech but showed worse jitter, shimmer, and harmonic-to-noise ratios. The two groups showed comparable VHI and speech intelligibility performance.

CONCLUSIONS

The ALT phonatory tube, a novel flap for reconstruction, can restore digestive and voice functions simultaneously. Compared with PLD use, ALT phonatory tube reconstruction yields an improved speech range and comparable levels of voice handicap and speech intelligibility, suggesting that the technique is a good alternative for patients after TLP.

Fascio-cutaneous-free flaps as primary reconstruction in salvage total laryngectomy

INTRODUCTION

Salvage total laryngectomy (STL) is the most common treatment for recurrent laryngeal cancer after (chemo)-radiotherapy [(C)RT]. In this scenario, a higher rate of local wound complications, such as pharyngo-cutaneous fistula (PCF) and pharyngo-esophageal stenosis (PES), is generally expected. The aim of the present study is to evaluate outcomes using a standardized reconstructive protocol.

METHODS

Between 2009 and 2019, patients undergoing STL after (C)RT were collected at two referral hospitals with the objective of evaluating surgical outcomes using a standardized reconstructive policy based on the use of fascio-cutaneous free flaps as inlay patch grafts and a long-lasting salivary bypass stent.

RESULTS

Fifty-five patients (mean age, 66 years; male-to-female ratio, 8:1) were included in the study. Previous treatments were RT in 22 (40%) patients, CRT in 21 (38.2%), and partial laryngeal surgery followed by adjuvant (C)RT in 12 (21.8%). Reconstruction was accomplished by radial forearm and anterolateral thigh free flaps in 16 (29.1%) and 39 (70.9%) patients, respectively. Flap success rate was 98.2%. Concerning postoperative complications, we encountered 3 PCFs (5.4%) and 1 PES (1.8%).

CONCLUSION

The standardized reconstructive protocol analyzed herein granted significantly lower rates of PCF and PES after STL compared with data available in the literature.

Swallowing disorders following free jejunal flap reconstruction of circumferential pharyngeal defect: Does Botox help?

OBJECTIVES

Free jejunal flap for circumferential pharyngeal reconstruction is associated with late-onset dysphagia, regurgitation and prolonged transit time. This study aims to assess the feasibility and efficacy of Botulinum toxin A (Botox) in alleviating such swallowing dysfunction.

MATERIALS AND METHODS

Twenty-six consecutive patients underwent free jejunal flap for circumferential pharyngeal reconstruction between January 2012 and December 2018. Outcomes were compared at 6, 12 and 24 months.

RESULTS

In the non-Botox group (n = 13), video-fluoroscopic and manometry studies demonstrated asynchronous contractions and retrograde propulsion. All patients complained of nasal regurgitation on thin fluids at 6, 12 and 24 months. Bolus residue accumulation along jejunal mucosal folds resulted in prolonged transit time. In the Botox group (n = 13), amplitude of asynchronous contractions were lower: 25.4 mmHg vs. 52.1 mmHg (p = 0.037) for thin fluids at 12 months. Three patients complained of nasal regurgitation on thin fluids at 6 months. All 3 were asymptomatic at 12 months. Transit time was shortened overall. Functional Oral Intake Scale was higher. MD Anderson Dysphagia Inventory global (72.5% vs 45.7%, p = 0.003) and functional (62.0% vs 40.6%, p = 0.012) subscales were significantly improved at 24 months.

CONCLUSION

Botox safely and effectively alleviates swallowing dysfunction associated with free jejunal flap for circumferential pharyngeal reconstruction.

Comparison of xenogeneic acellular dermal matrix and skin grafts in reconstruction of postoperative defects of hypopharyngeal cancer: A retrospective cohort study

Successful reconstruction after tumor resection facilitates rapid recovery and retention of good quality of life, and this is important for a successful operation. This study aimed to analyze and compare the application and efficacy of xenogeneic acellular dermal matrix (xeno-ADM) and abdominal skin graft in hypopharynx reconstruction.This is a retrospective cohort study that included 25 patients with posterior hypopharyngeal wall cancer who underwent partial hypopharyngectomy with laryngeal preservation. The patients were divided into 2 groups according to the repair materials used. Eleven patients were treated with xeno-ADM, and 14 patients with abdominal skin grafts for repairing hypopharyngeal mucosal defects. The intraoperative data, postoperative recovery time of eating function, graft contraction, infection and pharyngeal fistula rate, and 1-year survival rate of the 2 groups were analyzed and compared.Compared with skin grafts group (23.1 ± 5.8 days), the recovery time of eating function in xeno-ADM group was shorter (17.3 ± 6.4 days), (P = .026). Also the number of postoperative hospitalization days were less in the xeno-ADM group (18.5 ± 6.7 days) than in the skin grafts group (24.1 ± 5.6 days) (P = .035). Besides, no significant differences were observed in other comparisons between the 2 groups. Also no obvious rejection and severe graft contraction were observed in both the groups. All patients were successfully decannulated.Both xeno-ADM and abdominal skin grafts demonstrated good effects in the reconstruction of hypopharynx, but the recovery time of eating function in patients with xeno-ADM was faster, which may be due to rapid epithelialization. In addition, it avoids trauma of donor sites.

Single stage reconstruction of complex head and neck defects involving the skin with a single ALT flap: A ten year review

Background

Multicomponent defects of the head and neck involving the cervical skin pose a reconstructive challenge for microsurgeons and usually requires two flaps. However, many patients who undergo such surgical treatment had prior treatment with radiotherapy and the availability of recipient vessels for free flap reconstruction may be limited. The purpose of this study was to review our experience in the reconstruction of these extensive head and neck defects using a single ALT free flap.

Methods

A total of 21 patients with complex defects of the head and neck involving multiple anatomical subunits, including the overlying cervical skin, underwent reconstruction with a single ALT flap. The clinical, functional, and aesthetic outcomes of these patients were reviewed.

Results

The mean hospital stay was 24 days. There was one total flap loss due to pedicle thrombosis. The patient underwent a further ALT reconstruction with no postoperative complications. Cervical fistulas occurred in three patients, and all fistulas were healed by simple wound packing. Three patients with tracheal defect had a functional tracheostoma with adequate stomal patency. A modified barium swallowing study was performed on each patient, and all of them achieved total oral intake. Among them, two patients tolerated only a pureed diet.

Conclusions

Complex neck reconstruction can be accomplished with a single ALT flap with good clinical and functional results, minimal morbidity and quick recovery.

Partial pharyngolaryngectomy with infrahyoid flap: Our experience

AIM

We evaluated a cohort of advanced hypopharyngeal squamous cell carcinoma, treated with conservative surgery, reconstruction with infrahyoid flap and radio-chemotherapy.

METHODS

We used partial pharyngo-laryngectomy and radio-chemotherapy to treat fifty-seven patients with stage III-IV hypopharyngeal SCC from November 1994 to December 2011. Clinical examination and speech therapy evaluation were used for estimation of laryngeal function.

RESULTS

All patients received a partial pharyngo-laryngectomy. All patients underwent neck dissection; 56 patients received bilateral neck dissection. Reconstruction was achieved by infra-hyoid flap. Five-year overall and disease-specific survival rates were 54.4% and 61.4%, respectively. Successful laryngeal function preservation with complete five-year remission was achieved in 44% of the patients.

CONCLUSION

Selected even if advanced carcinomas of the hypopharynx maybe treated with partial pharyngo-laryngectomy with reconstruction with pedicled flap. Both oncological and functional results showed a good outcome.

Total laryngopharyngectomy with circumferential reconstruction: Helsinki institutional study

PURPOSE

Surgical complications after total laryngopharyngectomy (TLP) are common, reconstruction is challenging, and patients often lose their ability to swallow and speak. To evaluate these aspects, we analysed outcome after TLP.

METHODS

We reviewed all patients who underwent TLP and subsequent circumferential pharyngeal reconstruction through 2004-2017 at the Helsinki University Hospital.

RESULTS

For the 26 eligible patients, TLP was the primary treatment for 11 and salvage surgery for 15, followed by reconstruction with free flaps in 22 patients and pedicled flaps in 4. An early (≤ 30 days) pharyngocutaneous fistula developed in seven patients (27%; median time 13 days; range 6-26), and a late (> 30 days) fistula in five patients (19%; median time 370 days; range 46-785). In addition, ten patients (39%) developed an oesophageal stricture. Four patients (15%) resumed full oral feeding. A speech prosthesis was inserted for 15 patients (58%) and most of them could produce intelligible speech. We found acceptable survival figures for patients undergoing TLP both as a primary treatment and as salvage procedure: the overall survival at 1 year was 82% and 67%, and at 5 years 33% and 27%, respectively. Disease-specific survival at 1 year was 90% and 70%, and that at 5 years was 45% and 43%, respectively.

CONCLUSIONS

Despite fair survival, TLP carries a high risk for postoperative complications with limited functional outcome, thus necessitating cautious patient selection and surgical experience.

Treatment for postchemoradiotherapy hypopharyngeal stenosis: Pharyngoesophageal bypass using an anterolateral thigh flap-A case report

Radiation-induced pharyngoesophageal stenosis is a frequent and unwanted consequence of nonsurgical treatment of hypopharyngeal carcinomas. Current treatment mainly includes endoscopic dilatations, but a poor response to this modality and/or a severe stenosis may lead to a radical resection (pharyngolaryngectomy) and reconstruction with tubed flaps, which allow oral feeding but fail to preserve speech. In this report, we present a case of radiation-induced hypopharyngeal stenosis treated with a pharyngoesophageal bypass using an anterolateral thigh (ALT) flap with the intention of preserving the larynx. We describe the case of a 59-year-old male with severe pharyngoesophageal stenosis after chemoradiotherapy due to a squamous cell carcinoma, where conventional dilatation treatment failed to restore pharyngoesophageal passage of solids or liquids. Since the patient rejected a pharyngolaryngectomy due the loss of speech entailed, a pharyngoesophageal bypass was performed using an ALT flap. The flap measured 13 × 20 cm, which ensured a 4-cm-diameter tube and enough length to communicate the lateral pharyngeal wall with the cervical esophagus. Endoscopy did not reveal flap failure, and during the immediate postoperative period, the patient had a small cervical leak detected only by imaging that did not affect the skin and resolved with antibiotic treatment. The patient also required a tracheostomy on day 4 and initially had no passage of saliva through the bypass; we attributed this to edema that resolved spontaneously after 1 month with complete liquid and solid passage and laryngeal competence that led to tracheal decannulation. Good functional results were achieved both for speech and swallowing at 5-year follow-up. We believe that this procedure may be considered before performing a pharyngolaryngectomy for the treatment of a persistent benign stenosis in patients with a functional larynx.

Using intestinal segments during secondary salvage procedures after failed reconstructions of the cervical oesophagus

OBJECTIVES

The free anterolateral thigh (ALT) flap is commonly used for the reconstruction of the cervical oesophagus with satisfactory results. Its convenience and popularity make it a popular flap for reconstructive surgeons. The use of intestinal flaps, however, carries a higher level of technical difficulty and is normally performed as a primary reconstructive procedure. This report investigates the feasibility of intestinal flaps for the reconstruction of the cervical oesophagus and strategies to optimize its success when used as a secondary flap after primary ALT flap failure.

METHODS

We retrospectively reviewed 22 patients (age 39-72 years) who were men, between April 2013 and January 2015, with intestinal segments (free and pedicled ileocolon, jejunal and colon flaps) that were used secondarily to salvage failed primary free ALT flap reconstructions after hypopharyngeal cancer resection. Ten patients presented with leakage and 2 with tracheo-oesophageal fistulae as complications from the primary flap failure.

RESULTS

Oral intake commenced around 1-month postoperatively. One case of flap failure was observed. The majority had no major postoperative complications. Patients were followed up (6-27 months), and 21 cases of a secondary intestinal flap were successful with the restoration of oesophageal continuity and oral intake.

CONCLUSIONS

Intestinal flaps, free or pedicled, can be used secondarily after failed ALT flap reconstructions with minimal complications or morbidity. Intestinal flaps successfully allow restoration of gastrointestinal continuity with early commencement of oral intake and swallowing function.

Design of skin islands for a myocutaneous serratus anterior free flap-An anatomical study and clinical implication for pharyngeal reconstruction after laryngopharyngectomy

Objectives

The main purpose of this study was to evaluate flap size and flap design of skin islands in myocutaneous serratus anterior free flaps (SAFFs) in fresh cadavers and to further investigate whether myocutaneous SAFFs are suitable flaps for pharyngeal reconstruction after laryngopharyngectomy.

Methods

Dissection and injection of methylene blue were performed in 20 hemithoraces of 13 fresh cadavers to evaluate flap size and location of skin islands. Based on these pre‐clinical data, we performed pharyngeal reconstruction with myocutaneous SAFF in five patients after laryngopharyngectomy.

Results

Perfused skin paddles were found in all specimens with a mean size of perfused skin islands of 85.6 ± 49.8 cm². Lengths and widths of skin islands ranged from 10‐21 cm and 6‐20.5 cm respectively. Flap size did not significantly differ between males and females (P = 0.998), left compared to right hemithoraces (P = 0.468) and between paired specimens (P = 0.915). All skin islands were found within the upper 29.3%‐51.7% of hemithorax (calculated from axilla to costal arch), and between latissimus dorsi muscle posteriorly and anterior axillary line anteriorly. Accordingly, myocutaneous SAFFs were used for pharyngeal reconstruction after laryngopharyngectomy in five patients with advanced hypopharyngeal carcinomas. Three patients had uneventful courses, while one patient developed immediate intraoperative flap loss and another patient developed partial necrosis of SAFF on postoperative day 7.

Conclusion

Skin islands of SAFF have reliable blood supply, which allow harvest of large myocutaneous SAFFs that can be used also for pharyngeal reconstruction after laryngopharyngectomy.

Incorporating a continuous suction system as a preventive measure against fistula-related complications in head and neck reconstructive surgery

Background

Although previous studies have focused on determining prognostic and causative variables associated with fistula-related complications after head and neck reconstructive surgery, only a few studies have addressed preventive measures. Noting that pooled saliva complicates wound healing and precipitates fistula-related complications, we devised a continuous suction system to remove saliva during early postoperative recovery.

Methods

A continuous suction system was implemented in 20 patients after head and neck reconstructive surgery between January 2012 and October 2017. This group was compared to a control group of 16 patients at the same institution. The system was placed orally when the lesion was on the anterior side of the retromolar trigone area, and when glossectomy or resection of the mouth floor was performed. When the orohypopharynx and/or larynx were eradicated, the irrigation system was placed in the pharyngeal area.

Results

The mean follow-up period was 9.2±2.4 months. The Hemovac system was applied for an average of 7.5 days. On average, 6.5 days were needed for the net drain output to fall below 10 mL. Complications were analyzed according to their causes and rates. A fistula occurred in two cases in the suction group. Compared to the control group, a significant difference was noted in the surgical site infection rate (P<0.031).

Conclusions

Clinical observations showed reduced saliva pooling and a reduction in the infection rate. This resulted in improved wound healing through the application of a continuous suction system.

Free jejunal flap transfer containing multiple vascular pedicles for pharyngoesophageal reconstruction in conjunction with anterior mediastinal tracheostomy

BACKGROUND

When pharyngoesophagectomy is performed in conjunction with anterior mediastinal tracheostomy, reconstructing both the trachea and alimentary tract is extremely difficult. We developed a novel 1-stage reconstructive procedure using a single free jejunal flap containing multiple vascular pedicles to decrease postoperative morbidity and mortality. Free jejunal flap transfer with multiple vascular pedicles could offer a viable option for reducing associated life-threatening complications.

METHODS

We performed a retrospective review of 34 patients who underwent free jejunal flap transfer with multiple vascular pedicles in anterior mediastinal tracheostomy and pharyngoesophagectomy due to lesions involving both the airway and esophagus. In all cases, 1-stage reconstruction of the digestive tract and trachea was performed. Technical details and outcomes were analyzed.

RESULTS

All 34 jejunal flaps (100%) survived. Major morbidity classified as Clavien-Dindo grades III and IV occurred in 10 (29.4%) and 0 (0%) patients, respectively during hospitalization. With regard to common complications, anastomotic leakage from transferred jejunal flaps and surgical site infections occurred in 0 (0%) and 7 (20.6%) patients, respectively. Five (14.7%) patients experienced tracheal stoma dehiscence. Donor site morbidity was observed in 2 (5.9%) patients. The overall in-hospital mortality rate was 2.9%.

CONCLUSIONS

Our 1-stage reconstruction procedure achieved low morbidity and low mortality rates following anterior mediastinal tracheostomy and pharyngoesophagectomy. Only 1 jejunal flap transfer is needed to simultaneously reconstruct the trachea and alimentary tract in a safe and reliable manner with this procedure.

A Novel Application of Double-Paddle Peroneal Chimeric Flap as External Sentinel Monitor in Hypopharyngeal Reconstruction

OBJECTIVES

Monitoring the viability of buried free flaps in hypopharyngeal reconstruction is difficult. Various methods have been proposed to monitor these buried flaps, but limitations remain.

METHOD

We present a method of using double-paddle chimeric peroneal flaps that permanently externalizes a flap skin paddle as a monitoring paddle in hypopharyngeal reconstructions. This study was performed in a medical center in southern Taiwan; between 2013 and 2015, 10 patients underwent double-paddle chimeric peroneal flap reconstruction in advanced stages of hypopharyngeal cancer. We retrospectively reviewed the medical records from these surgeries, searching for either short-term postoperative complications or long-term follow-up morbidity and researched relevant articles for comparisons with other monitoring methods.

RESULTS

None of the 10 flaps underwent total loss. The rate of stenosis and that of fistula formation was 10%. The average postoperative hospital stay was 39 days. Six of 10 patients were able to resume at least a soft diet after reconstruction, and none of the patients experienced significant complications.

CONCLUSIONS

The peroneal flap is a useful flap because it is thin and pliable, has minimal donor site morbidity in patients without peripheral vascular disease, and has the potential of multiple skin paddles so that one skin paddle can be used for monitoring the buried flap. Using this method, direct clinical monitoring is feasible, and early detection of vascular complications is possible. Furthermore, the drawbacks of using a monitoring paddle produced by a deepithelialized bridge can be avoided.

The anterolateral thigh perforator flap in pharyngo-esophageal reconstruction

Today's customary techniques for pharyngo-esophageal reconstruction are jejunum and radial forearm free flaps. In this type of reconstruction, the jejunum flap is considered as the reference, but when its harvesting is not possible, the radial forearm flap is used. Since perforator flaps have begun to be developed, the anterolateral thigh flap (ATF) has become increasingly prominent in pharyngo-esophageal reconstruction. The aim of our study was to describe the use of the anterolateral perforator flap in pharyngo-esophageal reconstruction (indications, harvesting method, flap design) and to discuss its advantages and drawbacks as regards oral feeding and esophageal speech.

Fasciocutaneous free flaps for reconstruction of hypopharyngeal defects

OBJECTIVES/HYPOTHESIS

Different reconstructive options are available for defects following total laryngectomy (TL) and circumferential (CH) or partial hypopharyngectomy (PH). We evaluated the flap success, pharyngocutaneous fistula, and pharyngoesophageal stenosis rates in two groups of patients treated by different policies.

STUDY DESIGN

Comparison between two cohorts of patients treated by TL with PH/CH ± cervical esophagectomy and reconstructed according to different strategies.

METHODS

Group A (historical) was composed of 89 patients reconstructed by pectoralis major myocutaneous (PMMC), radial forearm (RF), and anterolateral thigh (ALT) flaps. A salivary bypass stent (SBPS) was not routinely applied and left in place for a maximum of 14 days. Forty-four (49%) patients received preoperative radiotherapy/chemoradiotherapy (RT/CRT). Group B (prospective) included 105 patients reconstructed by RF or ALT with long-lasting SBPS left in place for a maximum of 45 days. Sixty-one (59%) received preoperative RT/CRT.

RESULTS

In group A, flap failure occurred in four (4%) cases, and all were managed by PMMC. We encountered 22 (26%) fistulas and 14 (16%) stenoses. In group B, flap failure occurred in six (6%) cases and was managed by PMMC. We encountered seven (7%) fistulas and three (3%) stenoses. Comparing complications among the two groups, we encountered a statistically significant difference in favor of group B for both fistula (P < .001) and stenosis (P = .001). We did not evidence any significant difference in terms of flap success rate.

CONCLUSIONS

First-line application of RF and ALT free flaps with long-lasting SBPS in reconstruction after PH/CH allows obtaining reduced incidences of both fistula and stenosis.

Optimizing Outcomes in Pharyngoesophageal Reconstruction and Neck Resurfacing: 10-Year Experience of 294 Cases

BACKGROUND

Pharyngoesophageal reconstruction is a complex endeavor that poses many challenges. This 10-year series examines factors impacting the need for neck skin resurfacing and evaluates the impact of reconstructive modalities on outcomes.

METHODS

A review identified 294 patients who underwent pharyngoesophageal reconstruction from 2002 to 2012. Patients were divided based on neck skin resurfacing requirements. Patients undergoing neck resurfacing were further subdivided into reconstructive technique, including a second skin paddle or muscle component from the same free flap pedicle, a local flap, or a second free flap. All groups were compared by comorbidities, complications, and functional outcomes.

RESULTS

Of 294 patients, 179 (60.9 percent) required neck skin resurfacing. In the resurfaced group, there were 90 circumferential defects (50.3 percent) and 89 partial defects (49.7 percent). In the resurfaced group, 110 (61.4 percent) underwent reconstruction with a second skin paddle from the same free flap pedicle, 21 (11.7 percent) underwent reconstruction with a muscle component from the same pedicle, and 25 (13.9 percent) received a pectoralis major flap. There were five external paddle flap losses in the resurfaced group (2.8 percent) and no internal flap losses. Overall complications were similar among groups. The resurfaced group had a lower pharyngocutaneous fistula rate (4.5 percent) compared with the primary closure group (11.3 percent) (p = 0.026). Prior neck surgery and radiation therapy were strong predictors of neck skin resurfacing (p < 0.001).

CONCLUSIONS

Neck resurfacing is often required in salvage pharyngoesophageal reconstruction. Providing additional vascularized tissue over the neoconduit is predictive of lower pharyngocutaneous fistula rates. An algorithmic approach to neck resurfacing is presented.

Use of acellular dermal matrices in laryngotracheal and pharyngeal reconstruction: systematic review

Background:

Acellular dermal matrices are increasingly used in laryngotracheal and pharyngeal reconstruction, but specific indications and the type of acellular dermal matrix used vary. The authors systematically reviewed outcomes relating to acellular dermal matrix use in head and neck reconstruction.

Methods:

Electronic databases were searched through 1 May 2016 for literature on acellular dermal matrix use in laryngotracheal and pharyngeal reconstruction. Studies were appraised for surgical indications, outcomes and study design.

Results:

Eleven publications with 170 cases were included. Eight articles reported on acellular dermal matrix use in oncological reconstruction. Most studies were case series; no high-level evidence studies were identified. Graft extrusion was more common in non-oncological applications. In general, post-oncological reconstruction with an acellular dermal matrix demonstrated complication rates similar to those reported without an acellular dermal matrix.

Conclusion:

Evidence in support of acellular dermal matrix use in head and neck reconstruction is generally poor. Prospective comparative studies are required to define the indications, safety and effectiveness of acellular dermal matrices in laryngotracheal and pharyngeal reconstruction.

Comparison of the outcomes of free jejunal flap reconstructions of pharyngoesophageal defects in hypopharyngeal cancer and corrosive injury patients

INTRODUCTION

Free jejunal flap is one of the optimal choices for restoring upper digestive tract. The purpose of this study was to introduce the treatment strategies and to compare the outcomes of free jejunal flap for pharyngoesophageal reconstruction between hypopharyngeal cancer and chemical corrosive injured esophagus.

METHODS

From 2001 to 2012, patients who had been received esophageal reconstruction by free jejunal flap for pharyngoesophageal defect were divided into squamous cell carcinoma (SCC) group and corrosive chemical injury (CCI) group. All data on outcomes and complications including relevant radiographic investigations were collected retrospectively.

RESULTS

Sixteen patients were in SCC group and 9 patients in CCI group underwent free jejunal flap reconstruction. Two cases of flap failure were noted in SCC group, and no flap failure in CCI group-the total failure rate was 8% (2/25 patients). In SCC group, 5 of 16 patients (31.3%) developed fistula; however, no fistula in CCI group. One patient in SCC group and 3 patients in CCI group developed esophageal strictures. Other than early stricture (stricture <1 year) which reached significant difference, all of other complications were not statistically significant between two groups. The average follow-up time was 42 months.

CONCLUSIONS

Postoperative early stricture but lower fistula occurrence is expected in patients with corrosively injured esophagi. This helpful preliminary findings could not only early-check complication, but also better explanation and prepare were taken placed before operation.
