The pectoralis myofascial flap in pharyngolaryngeal surgery after radiotherapy

Vascularized Tissue to Reduce Fistula After Salvage Total Laryngectomy: A Network Meta-analysis

OBJECTIVE

Salvage laryngectomy is more predisposed to complications than primary operations, with pharyngocutaneous fistula (PCF) being among the most challenging to manage. Vascularized flaps are increasingly employed during salvage laryngectomy, with a previous review finding a PCF incidence of 31.2% and 22.2% after primary and flap-assisted closure respectively. We aim to better define the role of vascularized flaps after salvage laryngectomy by performing an updated review comparing the rate of PCF in those undergoing primary or vascularized flap-assisted closure.

DATA SOURCES

Pubmed/Medline, CINAHL, and CENTRAL.

REVIEW METHODS

An updated literature review was conducted of English language literature from 2003 to 2023. A random effects and network meta-analysis of odds ratios (OR) and pooled proportions were conducted.

RESULTS

Literature search found 31 studies, including seven from the previous review. Overall random effects pooled PCF rate was 25% (95% CI 0.21; 0.30, I2 = 72%, p = <0.01), whereas incidence in primary closure was 37% (95% CI 0.32; 0.43, I2 = 60%, p = <0.01) and 19% (95% CI 0.12; 0.20, I2 = 47%, p = <0.01) after flap closure. Pooled OR was 0.39 (95% CI 0.28; 0.55, I2 = 36%, p = 0.04) in favor of vascularized tissues. The number needed to treat was 6.5. The rate of PCF was lower after free and pedicled flaps, and on-lay and patch closure compared to primary closure techniques. Network meta-analysis found all combinations of closure techniques and vascularized tissue were superior to primary closure.

CONCLUSION

The updated analysis has demonstrated a widening in the rates of PCF between primary and vascularized flap-assisted closure. Surgeons should strongly consider the use of free or pedicled flaps in any salvage laryngectomy procedure. Laryngoscope, 134:2991-3002, 2024.

Pectoralis major muscle flap reconstruction after a total laryngectomy widened anteriorly: A case report

INTRODUCTION AND IMPORTANCE

The pectoralis major flap is one of the leading regional pedicled flaps for reconstructive surgery of the head and neck, particularly in oncology after tumor resection. Despite the increasing use of free flaps, this type of flap is still highly recommended in defined indications. It is a highly reliable flap in terms of viability.

CASE PRESENTATION

We report the case of a man treated in our ENT department for a squamous cell carcinoma of the three laryngeal stages, anteriorly very extensive and requiring total laryngectomy extended to the skin and subcutaneous planes opposite, followed by reconstruction with a flap of the pectoralis major muscle. Post-surgical outcome was excellent.

CLINICAL DISCUSSION

Aryan was the first person to describe the use of the pectoralis major muscle flap. Since then, several studies have demonstrated the great value of this flap in face and neck reconstruction, thanks to its wide indications and excellent viability rate.

CONCLUSION

The pectoralis major muscle flap represents a valuable reconstructive option for substance loss in the cervicofacial region despite the great development of microsurgery and free flaps.

Prophylactic pectoralis major flap to compensate for increased risk of pharyngocutaneous fistula in laryngectomy patients with low skeletal muscle mass (PECTORALIS): study protocol for a randomized controlled trial

BACKGROUND

Total laryngectomy (TL) is a surgical procedure commonly performed on patients with advanced laryngeal or hypopharyngeal carcinoma. One of the most common postoperative complications following TL is the development of a pharyngocutaneous fistula (PCF), characterized by a communication between the neopharynx and the skin. PCF can lead to extended hospital stays, delayed oral feeding, and compromised quality of life. The use of a myofascial pectoralis major flap (PMMF) as an onlay technique during pharyngeal closure has shown potential in reducing PCF rates in high risk patients for development of PCF such as patients undergoing TL after chemoradiation and low skeletal muscle mass (SMM). Its impact on various functional outcomes, such as shoulder and neck function, swallowing function, and voice quality, remains less explored. This study aims to investigate the effectiveness of PMMF in reducing PCF rates in patients with low SMM and its potential consequences on patient well-being.

METHODS

This multicenter study adopts a randomized clinical trial (RCT) design and is funded by the Dutch Cancer Society. Eligible patients for TL, aged ≥ 18 years, mentally competent, and proficient in Dutch, will be enrolled. One hundred and twenty eight patients with low SMM will be centrally randomized to receive TL with or without PMMF, while those without low SMM will undergo standard TL. Primary outcome measurement involves assessing PCF rates within 30 days post-TL. Secondary objectives include evaluating quality of life, shoulder and neck function, swallowing function, and voice quality using standardized questionnaires and functional tests. Data will be collected through electronic patient records.

DISCUSSION

This study's significance lies in its exploration of the potential benefits of using PMMF as an onlay technique during pharyngeal closure to reduce PCF rates in TL patients with low SMM. By assessing various functional outcomes, the study aims to provide a comprehensive understanding of the impact of PMMF deployment. The anticipated results will contribute valuable insights into optimizing surgical techniques to enhance patient outcomes and inform future treatment strategies for TL patients.

Perioperative Factors Aggravating Pharyngocutaneous Fistula After Total Laryngectomy: A Single-Center Retrospective Analysis Using the Clavien-Dindo Classification

BACKGROUND

Pharyngocutaneous fistula formation represents a major postoperative complication following total laryngectomy. We aimed to investigate the risk factors for pharyngocutaneous fistula development after total laryngectomy and to identify factors that lead to severe cases of pharyngocutaneous fistula.

METHODS

Patients who underwent total laryngectomy between January 2013 and February 2021 were included in the study and were divided into 2 groups: Those with and without pharyngocutaneous fistula. The severity of pharyngocutaneous fistula was graded using the Clavien-Dindo classification.

RESULTS

Patients with pharyngocutaneous fistula experienced longer operative time, greater intraoperative blood loss, greater decrease in perioperative hemoglobin level, and longer postoperative hospitalization. Unlike in lower-severity cases, patients with grade IIIb pharyngocutaneous fistula underwent preoperative radiotherapy or chemoradiotherapy; preoperative treatment was thus a risk factor for higher severity of pharyngocutaneous fistula (odds ratio, 35; P = 0.004).

CONCLUSION

Salvage laryngectomy was found to be a predictor of severe pharyngocutaneous fistula development. Prolonged operative time, increased intraoperative blood loss, and decreased postoperative hemoglobin level were found to be predictors of postlaryngectomy pharyngocutaneous fistula formation.

Predictive Value of Risk Factors for Pharyngocutaneous Fistula After Total Laryngectomy

OBJECTIVES

To assess the predictive value of various risk factors for pharyngocutaneous fistula (PCF) after total laryngectomy.

METHODS

The characteristics of each study were collected from six databases up to January of 2022. Risk for bias was assessed using the QUADAS-2 tool.

RESULTS

A total of 58 studies in 9845 patients were included in the analysis. The incidence of PCF was 21.69%, 95% confidence intervals (CI) [0.20; 0.24] in the included studies. Age (OR = 1.33, 95% CI [1.12; 1.58]), postoperative anemia (OR = 2.29, 95% CI [1.47; 3.57]), diabetes mellitus (OR = 1.81, 95% CI [1.20; 2.71]), tumor site (above or below the glottis) (OR = 1.47, 95% CI [1.15; 1.88]), previous radiation therapy (OR = 2.06, 95% CI [1.56; 2.72]), previous tracheostomy (OR = 1.26, 95% CI [1.04; 1.53]), surgery timing (salvage vs. primary) (OR = 2.08, 95% CI [1.46; 2.97]), extended total laryngectomy (including pharyngectomy) (OR = 1.96, 95% CI [1.28; 3.00]), primary tracheoesophageal puncture (OR = 0.61, 95% CI [0.40; 0.93]), and postoperative hypoproteinemia (OR = 9.98, 95% CI [3.68; 27.03]) were significantly associated with the occurrence of PCF. In view of predictive ability, postoperative hypoproteinemia showed the highest accuracy (sensitivity = 51%, specificity = 90%, area under the curve = 0.84).

CONCLUSION

Multiple patient-, disease-, and surgery-related factors are risk factors for PCF. In particular, postoperative hypoproteinemia could be a good predictive factor for PCF in patients undergoing total laryngectomy. Laryngoscope, 133:742-754, 2023.

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.

Pectoralis major muscle flap use in a modern head and neck free flap practice

PURPOSE

Pectoralis major muscle flaps (PMMF) are a commonly used reconstructive modality to repair head and neck defects. As the use of free flap reconstruction is increasingly practiced in the head and neck, the role of the PMMF may be changing as well. This study sought to analyze indications and outcomes for PMMF following head and neck resections from one surgeon's experience.

MATERIALS AND METHODS

Retrospective review from December 1, 2013 through September 30, 2017 at a tertiary care academic medical center. Indications for the PMMF were examined as well as surgical outcomes. Basic demographic data, patient head and neck cancer history, history of radiation and/or chemotherapy, and history of previous reconstructive procedures were obtained and compared across all subjects.

RESULTS

Forty patients underwent a PMMF within the designated time frame. The majority of patients were male (83%) and the average age was 65 years (range 55.4-74.6 years). Of the 40 cases, 9 of the PMMFs were performed as primary reconstruction of the defect. In the remaining 31 cases, these flaps were utilized as a secondary reconstructive option following fistula formation (13), dehiscence (6), need for an additional flap for recurrent disease (6) infection (4), or major bleeding (2). In every case that it was utilized, the PMMF was the definitive reconstruction. Within the same time frame, 429 free flaps were performed by the same surgeon, with an average of 125 free flaps performed yearly. The rate of total flap failure overall was 3.9%. The other failed free flap reconstructive options used besides a PMMF were secondary free flaps (11), local wound care (4), or obturator placement (2). The secondary pectoralis flaps occurred following 7.2% of free flaps with total or partial failure that were performed within the same time range. The indications for the PMMF did not change or evolve during the time frame of the study.

CONCLUSIONS

Although free flaps were performed with far greater frequency than PMMFs at our institution, the PMMF demonstrated continued utility as a secondary reconstructive option. For a surgeon who performs a high volume of free flaps, preservation of the pectoralis muscle and associated vasculature for possible later secondary reconstruction should be considered due to its strong efficacy.

Salvage total laryngectomy: is a flap necessary?

Introduction

Pharyngocutaneous fistula is the most significant complication after salvage total laryngectomy in patients who have received previous treatment with radiotherapy with or without chemotherapy.

Objective

Our purpose is to review the fistula rate in radiated patients undergoing salvage total laryngectomy, to determine if the use of pectoralis major flap interposition reduces the incidence and duration of fistula and to examine other risk factors.

Methods

We made a retrospective review of patients undergoing salvage total laryngectomy for exclusively larynx cancer after failure of primary curative radiotherapy between 2000 and 2017. General data from patients, risk factors and other complications were analyzed.

Results

We identified 27 patients whose mean age was 66.4 years, mainly male (92.5%). The primary closure group without pectoralis major flap included 14 patients, and the group with pectoralis major flap closure included 13 patients. Pharyngocutaneous fistula was present in 15 patients (55.5%). Global pharyngocutaneous fistula rate was higher in the group of patients without pectoralis major flap comparing with those were the flap was interposed (78.6% versus 30.8%, p = 0.047). Also the pharyngocutaneous fistulas which need to be repaired with surgery (64.3% versus 7.7%, p = 0.03) and large pharyngostomes (64.3% versus 0%, p = 0.0004) were present in a higher rate in the group closed primary without pectoralis major flap. We did not find other risk factors with statistical significance. Oral diet initiation (84 days versus 21.5 days, p = 0.039) and the duration of hospitalization (98.3 days versus 27.2 days, p = 0.0041) were much lower in patients with a preventive pectoralis major flap. Two patients died as a consequence of complications of large pharyngostomes.

Conclusions

Prophylactic pectoralis major flap reduced the incidence, severity and duration of fistula and should be considered during salvage total laryngectomy.

Post-operative complications due to salvage total laryngectomy for recurrent laryngeal cancer after radiotherapy - a multicentre retrospective study

Background: Few studies have demonstrated the utility of pharyngeal interposition graft (PIG) applying pectoralis major myocutaneous flap (PMMCF) by comparing pharyngocutaneous fistula (PCF) rates.Objective: The objective of this retrospective study was to clarify the utility of PIG applying PMMCF in reducing post-operative complications due to salvage total laryngectomy (STL).Material and methods: STL was performed in 59 patients with recurrent laryngeal cancer after radiotherapy, comprising 37 non-PMMCF patients and 22 PMMCF patients. The primary endpoint was PCF rate. Comparisons were made between two groups: a group with simple closure not using PMMCF (non-PMMCF group), and the other with PMMCF used in a PIG (PMMCF group).Results: PCF occurred in 15 of the 59 subjects (25.4%), including 13 of the 37 patients in the non-PMMCF group (35.1%) and 2 of the 22 patients in the PMMCF group (9.1%). PCF rate was significantly lower in the PMMCF group than in the non-PMMCF group (p = .033).Conclusions and significance: We demonstrated that PIG applying PMMCF significantly reduced the PCF rate due to STL. In the future, surgeons need to conduct research focused on additional innovations to reduce post-operative complications as much as possible.

Risk factors of pharyngocutaneous fistula after total laryngectomy: a systematic review and meta-analysis

OBJECTIVE

The purpose of this study was to systematically evaluate the risk factors of pharyngocutaneous fistula (PCF) after total laryngectomy.

METHODS

We systematically searched Pubmed, Web of Science, Cochrane Library, and Embase databases and included the literature according to the inclusion and exclusion criteria.

RESULTS

A total of 52 studies with 8605 patients were included in the meta-analysis. The total incidence of PCF was 21% (1808/8605). Meta-analysis results indicated that age (OR = 1.29, 95% CI 1.06-1.58, P = 0.01), smoking (OR = 1.62, 95% CI 1.27-2.07, P < 0.01), COPD (chronic obstructive pulmonary disease) (OR = 1.62, 95% CI 1.19-2.22, P < 0.01), CAD (coronary atherosclerotic heart disease) (OR = 1.82, 95% CI 1.36-2.45, P < 0.01), T-stage (OR = 0.81, 95% CI 0.67-0.98, P = 0.03), previous radiotherapy (OR = 2.41, 95% CI 2.00-2.90, P < 0.01), preoperative albumin (OR = 2.95, 95% CI 1.47-5.91, P < 0.01), preoperative hemoglobin (OR = 1.97, 95% CI 1.28-3.03, P < 0.01), tumor site (OR = 0.28, 95% CI 0.22-0.36, P < 0.01), and treatment method (OR = 1.85, 95% CI 1.44-2.38, P < 0.01) were risk factors associated with PCF.

CONCLUSIONS

In our study, age, smoking, COPD, CAD, T-stage, previous radiotherapy, preoperative albumin, preoperative hemoglobin, tumor site, and treatment method were risk factors of PCF.

The Pectoralis Major Island Flap: Short Scar Modified Muscle-Sparing Harvesting Technique Improves Aesthetic Outcome in Reconstructive Head and Neck Surgery

BACKGROUND

Pectoralis major flap reconstruction is often associated with large unappealing scars in head-neck surgery. We recently established an alternative harvesting technique that improves aesthetic outcome.

OBJECTIVES

The objective of this study was to demonstrate a modified surgical technique that harvests the pectoralis major muscle as an island flap and focuses on minimizing incision lines and applying a muscle-sparing approach.

METHODS

A retrospective analysis covering the period 2008-2018 was conducted. Patients who underwent pectoralis major island flap reconstruction for fistula prophylaxis after salvage laryngectomy at the Medical University of Innsbruck were included. Flap harvesting was performed subcutaneously using two small incision lines, thereby sparing the clavicular and upper sternocostal aspects of the pectoralis muscle.

RESULTS

Twenty-three patients with squamous cell carcinoma of the larynx (n = 19) or pharynx (n = 4) underwent salvage laryngectomy and consecutive reconstruction using a pectoralis major island flap and our muscle-sparing technique. Mean overall operation time was 147 ± 48.6 min. The majority (70%) of patients had an uneventful course of recovery and showed satisfying aesthetic results and low donor site morbidity as compared to traditional harvesting techniques. Six (26%) patients had major complications that required surgical revision. Three (13%) cases were complicated with fistulas.

CONCLUSION

The pectoralis major island flap is shown to be reliable in otolaryngeal surgery. This surgical technique minimizes scarring and preserves thoracic wall architecture by taking a less invasive approach, thereby improving aesthetic outcome and reducing overall patient morbidity.

Use of pectoralis major myofascial flap on the prevention of pharyngocutaneous fístula in salvage laryngectomy after chemoradiotherapy

Background: Pharyngocutaneous fístula (PCF) is a major complication of salvage laryngectomies, mainly secondary to the effect of radiotherapy. Aims/objectives: Our main objective is to study the effect of pectoralis major myofascial flap (PMMF) on the prevention of PCF. Materials and methods: We studied all total laryngectomies (TL) performed between 2001 and 2018, noting the use of previous chemoradiation, the type of suture and the use of flaps. We recorded and compared the incidence of PCF in all groups. Results: A total of 146 patients were included, divided into a primary TL group (117 patients) and salvage TL (29 patients). PMMF was used in 62% of salvage TLs. The rates of PCF were 5.98% in primary TL and 17.2% in salvage procedures. Among the salvage TL group, in patients with pharyngeal closure alone, a PCF developed in 36.4% of cases, compared to 5.56% in the PMMF group. We found a similar rate of fistulae when comparing primary TL and salvage TL with PMMF, highlighting the protective effect of the flap. Conclusions and significance: The use of PMMF in salvage TL reduces the incidence of PCF, achieving a rate similar to that attained with primary TL.

Defining the low-risk salvage laryngectomy-A single-center retrospective analysis of pharyngocutaneous fistula

Objectives

Salvage total laryngectomies (STL) are not a homogeneous group. Most will fall into two groups: i) Patients with previous AJCC stage I/II larynx cancer who have had radiotherapy to the larynx only (STL‐LOR), or ii) Patients who have had previous AJCC stage III/IV larynx cancer and subsequent radiotherapy to the larynx and draining nodal basins with concurrent cisplatin chemotherapy (STL‐CRT). We aimed to compare PCF rates following STL in these two groups.

Methods

A retrospective review of the department's cohort between January 2010 and August 2015 was conducted.

Results

Seventy‐seven patients underwent total laryngectomy for larynx cancer between January 2010 and August 2015. There were 10 post‐laryngectomy fistulas (13.0%). Three of these occurred in the 38 patients undergoing primary total laryngectomy (PTL), and seven in the 39 patients undergoing STL, rates of 7.9% and 17.9%, respectively. Twenty‐two patients had received radiation to the larynx alone without chemotherapy (STL‐LOR) for initial Stage I/II disease. Eleven patients had received laryngeal and neck irradiation plus cisplatin chemotherapy (STL‐CRT) for initial stage III/IV disease. Of the 22 STL‐LOR patients, two developed PCF (9.1%). Of the 11 STL‐CRT patients, five developed PCF. There was no difference in the rate of PCF between PTL and STL‐LOR. There was a statistically significant increase in PCF in STL‐CRT versus PTL (p = .009) and in PCF in STL‐CRT versus STL‐LOR (p = .027).

Conclusion

Salvage laryngectomies are often treated as a homogenous group. We demonstrate that PCF rates vary significantly depending on preoperative radiation fields and the use of chemotherapy.

Prevention of pharyngocutaneous fistula in salvage total laryngectomy: role of the pectoralis major flap and peri-operative management

OBJECTIVE

This study aimed to evaluate the impact of an onlay pectoralis major flap in reducing the incidence of pharyngocutaneous fistula after salvage total laryngectomy and determine the complications of pectoralis major flap reconstruction.

METHODS

A retrospective study was conducted of consecutive patients who underwent salvage total laryngectomy between 1995 and 2016. The pharyngeal defects were primarily closed with or without the pectoralis major flap.

RESULTS

Of 64 patients, 34 had primary pharyngeal closure alone (control group) and 30 received an onlay pectoralis major flap (pectoralis major flap group). The overall fistula rate was 15.6 per cent, with 17.6 per cent occurring in the control group and 13.3 per cent in the pectoralis major flap group (p = 0.74). The incidence rates of voice failure (p = 0.02) and shoulder disability (p < 0.001) were significantly higher in the pectoralis major flap group.

CONCLUSION

The pectoralis major flap in salvage total laryngectomy did not decrease the pharyngocutaneous fistula rate, and the incidence of flap-related complications was high. Appropriate surgical technique and post-operative care may reduce the incidence of pharyngocutaneous fistula.

Hypothyroidism and Wound Healing After Salvage Laryngectomy

BACKGROUND

Patients undergoing salvage laryngectomy are predisposed to radiation-induced hypothyroidism and impaired wound healing secondary to the tissue effects of prior treatment. The impact of hypothyroidism on postoperative wound healing is not established.

METHODS

A single-institution retrospective case series was performed. The inclusion criteria specified preoperatively euthyroid adults who underwent salvage laryngectomy with concurrent neck dissection between 1997 and 2015 for persistent or recurrent laryngeal squamous cell carcinoma after radiation or chemoradiation therapy (n = 182). The principal explanatory variable was postoperative hypothyroidism, defined as thyroid-stimulating hormone (TSH) higher than 5.5 mIU/L. The primary end points of the study were pharyngocutaneous fistulas and wounds requiring reoperation. Multivariate analysis was performed.

RESULTS

The fistula rate was 47% among hypothyroid patients versus 23% among euthyroid patients. In the multivariate analysis, the patients who experienced hypothyroidism in the postoperative period had a 3.6-fold greater risk of fistula [95% confidence interval (CI) 1.8-7.1; p = 0.0002]. The hypothyroid patients had an 11.4-fold greater risk for a required reoperation (24.4 vs 5.4%) than the euthyroid patients (95% CI 2.6-49.9; p = 0.001). The risk for fistula (p = 0.003) and reoperation (p = 0.001) increased with increasing TSH. This corresponds to an approximate 12.5% incremental increase in the absolute risk for fistula and a 10% increase in the absolute risk for reoperation with each doubling of the TSH.

CONCLUSION

Postoperative hypothyroidism independently predicts postoperative wound-healing complications. The association of hypothyroidism with fistula formation may yield opportunities to modulate wound healing with thyroid supplementation or to provide a biomarker of wound progression.

Methods to reduce postoperative surgical site infections after head and neck oncology surgery

Head and neck cancer surgery is often a complex multi-step procedure that includes major resections, vascularised tissue reconstruction, and extensive neck dissection. The upper aerodigestive tract mucosal lining is often disrupted during surgery, which requires the management of a clean-contaminated field and the need to reconstruct the mucosal lining. With bacterial contamination, surgical site infections (SSI) are a serious complication that can result in delayed wound healing, wound breakdown, fistula formation, and compromised tissue reconstruction. Methods to reduce SSI in patients with head and neck cancer have been intensely researched, yielding evolving and varied practice patterns. In this Review, we outline the data supporting perioperative antibiotic prophylaxis for clean-contaminated surgeries, which suggest that clindamycin is an inadequate prophylactic antibiotic therapy in the reduction of SSI, and that prolonged antibiotic courses have no established benefit. For salvage laryngectomy after radiotherapy with or without chemotherapy, reconstruction with vascularised tissue reduces the frequency and severity of pharyngocutaneous fistula formation. These evidence-based recommendations have been shown to reduce the chance of SSI after head and neck surgery.

Role of the pectoralis major myofascial flap in preventing pharyngocutaneous fistula following salvage laryngectomy

Objective:

This study aimed to assess the utility of onlay pectoralis major myofascial flap in preventing pharyngocutaneous fistula following salvage total laryngectomy.

Methods:

A retrospective analysis was performed of 172 patients who underwent salvage laryngectomy for recurrent carcinoma of the larynx or hypopharynx between 1999 and 2014. One hundred and ten patients underwent primary closure and 62 patients had pectoralis major myofascial flap onlay.

Results:

The overall pharyngocutaneous fistula rate was 43 per cent, and was similar in both groups (primary closure group, 43.6 per cent; onlay flap group, 41.9 per cent; p = 0.8). Fistulae in the onlay flap group healed faster: the median and mean fistula duration were 37 and 55 days, respectively, in the primary closure group and 20 and 25 days, respectively, in the onlay flap group (p = 0.008).

Conclusion:

Use of an onlay pectoralis major myofascial flap did not decrease the pharyngocutaneous fistula rate, although fistula duration was shortened. A well-designed randomised-controlled trial is needed to establish parameters for its routine use in clinical practice.

Using a sternocleidomastoid muscle flap to prevent postoperative pharyngocutaneous fistula after total laryngectomy: a study of 88 cases

Complications of total laryngectomy can have serious implications for the final outcome of treatment, including pharyngocutaneous fistula. We conducted a retrospective study of surgical techniques to determine how to best prevent or decrease the incidence of pharyngocutaneous fistula following total laryngectomy. We reviewed the hospital records of all patients who had undergone total laryngectomy for laryngeal carcinoma at Ghaem Hospital in Mashhad, Iran, from March 1989 through February 2005. We identified 88 such patients-80 men and 8 women. We divided this cohort into two groups according to the type of pharyngeal defect closure they received. A total of 37 patients-31 men and 6 women (mean age: 61.4 ± 5.9 yr) underwent primary closure along with a sternocleidomastoid muscle (SCMM) flap (flap group). The other 51 patients-49 men and 2 women (mean age: 61.3 ± 4.4 yr)-underwent standard primary closure without creation of an SCMM flap (nonflap group). Overall, postoperative pharyngocutaneous fistula occurred in 9 of the 88 patients (10.2%)-1 case in the flap group (2.7%) and 8 cases in the nonflap group (15.7%). The difference between the two groups was statistically significant (p < 0.001; odds ratio = 0.612, 95% confidence interval = 0.451 to 0.832), independent of other factors. We found no correlation between fistula development and age (p = 0.073), sex (p = 0.065), or tumor location (p = 0.435). Likewise, we found no correlation between tumor location and either sex (p = 0.140) or age (p = 0.241). We conclude that including an SCMM flap in the surgical process would significantly decrease the development of fistula, regardless of age, sex, and tumor site.

Pharyngoesophageal Suturing Technique May Decrease the Incidence of Pharyngocutaneous Fistula following Total Laryngectomy

Objectives. A pharyngocutaneous fistula (PCF) following total laryngectomy is associated with increased morbidity and severe life threatening complications. We aimed to review our experience with the PCF following total laryngectomy and determine the impact of previously reported risk factors on the development of PCF in our patients. Methods. The medical records of 20 patients who had a total laryngectomy operation were retrospectively analyzed. The association between the proposed risk factors and the incidence of the PCF was investigated. Results. Comparison of the suture techniques used for the closure of the pharynx (either continuous Cushing type or interrupted) yielded that primary interrupted sutures had a significantly higher incidence of PCF formation (p < 0.05). Although it was not statistically significant, diabetes mellitus was also associated with increased PCF formation (p > 0.05). No significant difference was observed between the PCF and non-PCF groups in terms of other proposed risk factors (p > 0.05).  Conclusions. The main risk factor associated with PCF was found to be the type of pharyngeal closure technique. A vertical closure with a Cushing type continuous suture may be more successful than interrupted sutures in preventing a PCF.

Pharyngocutaneous fistula after total laryngectomy: a single-institution experience, 2001-2012

PURPOSE

The purpose of this study was to determine the incidence of and risk factors for pharyngocutaneous fistula in patients undergoing total laryngectomy at a single institution.

MATERIALS AND METHODS

The records of 59 patients undergoing primary or salvage total laryngectomy at our institution from 2001 to 2012 were retrospectively reviewed. Data collected included patient, tumor and treatment characteristics, and surgical technique. Risk factors were analyzed for association with pharyngocutaneous fistula formation.

RESULTS

Twenty patients (34%) developed fistulas. Preoperative tracheostomy (OR 4.1; 95% CI 1.3-13 [p=0.02]) and low postoperative hemoglobin (OR 9.1; 95% CI 1.1-78 [p=0.04]) were associated with fistula development. Regarding surgical technique, primary sutured closure of the total laryngectomy defect had the lowest fistula rate (11%). In comparison, primary stapled closure and pectoralis onlay flap over primary closure had nonsignificantly increased fistula rates (43%, OR 6.0; 95% CI 1.0-37.3 [p=0.06] and 25%, OR 2.7; 95% CI 0.4-23.9 [p=0.38], respectively). Pectoralis flap incorporated into the suture line had a significantly increased fistula rate (50%, OR 7.1; 95% CI 1.4-46 [p=0.02]). After stratification for salvage status, patient comorbidities were associated with fistula in non-salvage cases whereas disease-related characteristics were associated with fistula in salvage cases. Fistula development was associated with increased length of hospital stay (p<0.001) and increased time before oral diet initiation (p<0.001).

CONCLUSIONS

Pharyngocutaneous fistula is a common complication of total laryngectomy. Preoperative tracheostomy, postoperative hemoglobin, and surgical technique are important in determining the risk of fistula.

Predictive factors for pharyngocutaneous fistulization after total laryngectomy

OBJECTIVES

Postoperative complications, especially pharyngocutaneous fistulization (PCF), are more frequent after total laryngectomy (TL) performed for salvage after (chemo)radiotherapy than after primary TL. The aim of this study was to identify the incidence of PCF, predictive factors for PCF, and the relationship of PCF to survival.

METHODS

We performed a retrospective chart review of 217 consecutive patients treated with TL between 2000 and 2010. Univariate and multivariable analysis with logistic regression was used to identify factors associated with PCF. We used a Kaplan-Meier survival analysis.

RESULTS

The overall incidence of PCF was 26.3% (57 of 217 cases). The incidence of PCF after primary TL was 17.1% (12 of 70), that after salvage TL was 25.5% (25 of 98), that after TLE for a second primary was 37.5% (9 of 24), and that after TL for a dysfunctional larynx was 44.0% (11 of 25). The predictive factors for PCF were hypopharynx cancer (odds ratio [OR], 3.67; 95% confidence interval [CI], 1.74 to 7.71; P = .001), an albumin level of less than 40 g/L (OR, 2.20; 95% CI, 1.12 to 4.33; P = .022), previous chemoradiotherapy (OR, 3.38; 95% CI, 1.34 to 8.52; P = .010), more-extended pharyngeal resection (P = .001), and pharynx reconstruction (P = .002). The median duration of survival was 30 months (95% CI, 17.5 to 42.5); the 2-year overall survival rate was 54%. The median duration of survival of patients with PCF was 23 months (95% CI, 9.4 to 36.6), and that of those without PCF was 31 months (95% CI, 15.0 to 47.0; P = .421). The 2-year overall survival rate was 48% in patients with PCF and 57% in those without PCF (P = .290).

CONCLUSIONS

Incidence of PCF after TL is significantly higher in patients with hypopharynx cancer, previous chemoradiotherapy, a low albumin level, more-extended pharyngeal resection, or pharynx reconstruction. The occurrence of PCF does not influence the rate of survival.

Pectoralis major myofascial onlay and myocutaneous flaps and pharyngocutaneous fistula in salvage laryngectomy

OBJECTIVES/HYPOTHESIS

To review the fistula rate in irradiated patients undergoing salvage laryngectomy, compare the effect of closure type on fistula rate, and examine possible perioperative risk factors that might contribute to an increased fistula rate.

STUDY DESIGN

Case series with chart review.

METHODS

We conducted a retrospective review of the University of Pittsburgh head and neck tumor registry and identified 73 patients from 1998 to 2011 who had received prior radiation before total laryngectomy or salvage laryngectomy and who had either primary closure, pectoralis major myofascial (PMMF) flap onlay, or pectoralis major myocutaneous (PMMC) flap.

RESULTS

Fistula was more common in patients who underwent initial primary closure (45%) than in patients who had immediate PMMF onlay (10.5%). The fistula rate for patients who underwent immediate PMMC flap was 28.6%, intermediate to primary closure and PMMF flap. Several factors were evaluated for relationship to fistula, but no significant associations were identified. However, patients with fistula tended to have longer inpatient stays and may have been more likely to have a history of cardiovascular or hypoxic disease.

CONCLUSION

Pharyngocutaneous fistula is a well-established complication of total laryngectomy and is especially a concern in patients with a previous history of radiation. Our retrospective review demonstrates that PMMF onlay flap appears to be more effective in reducing the rate of fistula compared to primary closure in these patients. Myocutaneous augmentation flaps, in contrast, have a fairly high fistula rate and may be better replaced with alternative closures such as free flaps.

Pectoralis major myofascial flap in salvage laryngectomy

Objective:

The main purpose of this study was to evaluate the effect of the pectoralis major myofascial flap on pharyngocutaneous fistula formation and time to oral feeding.

Methods:

This retrospective study reviewed 155 total laryngectomies. Patients were divided into two main groups. Group 1 included 110 patients who were treated primarily by total laryngectomy and group 2 comprised 45 patients who were treated by salvage laryngectomy with or without a pectoralis major myofascial flap.

Results:

The use of a pectoralis major myofascial flap did not have a significant effect on pharyngocutaneous fistula formation in the salvage group (p = 0.376). When comparing the oral feeding day of patients with pharyngocutaneous fistula, a significant difference was observed between the salvage group with pectoralis major myofascial flap reinforcement and the salvage group without pectoralis major myofascial flap reinforcement (p = 0.004).

Discussion:

Our study demonstrated that pectoralis major myofascial flap reinforcement did not decrease the rate of pharyngocutaneous fistula formation. Instead, it prevented the formation of large fistulas that would require surgical management, and showed a similar time to oral feeding and length of hospital stay to primary laryngectomy.

Management of advanced laryngeal cancer

Squamous cell carcinoma of the larynx continues to be the commonest head and neck cancer in many Western countries. The larynx plays a key role for many essential functions, including breathing, voice production, airway protection, and swallowing. The goals of laryngeal cancer treatment are thus to provide best possible oncologic control, while optimizing functional outcomes. In recent decades, the treatment paradigm for advanced laryngeal cancer has shifted from one of primary surgery (total laryngectomy) as gold standard, toward non-surgical organ-preserving treatment using radiotherapy or chemoradiotherapy. However, concerns have emerged regarding functional outcomes after chemoradiotherapy, as well as possible decreased overall survival in patients with laryngeal cancer. The purpose of the present review is to review surgical and non-surgical options for treatment of advanced laryngeal cancer, as well as the evidence supporting each of these.

Vascularized tissue to reduce fistula following salvage total laryngectomy: a systematic review

OBJECTIVES/HYPOTHESIS

Pharyngocutaneous fistulae (PCF) are known to occur in nearly one-third of patients after salvage total laryngectomy (STL). PCF has severe impact on duration of admission and costs and quality of life and can even cause severe complications such as bleeding, infection and death. Many patients need further surgical procedures. The implications for functional outcome and survival are less clear. Several studies have shown that using vascularized tissue from outside the radiation field reduces the risk of PCFs following STL. This review and meta-analysis aims to identify the evidence base to support this hypothesis.

DATA SOURCES

English language literature from 2004 to 2013 REVIEW METHODS: We searched the English language literature for articles published on the subject from 2004 to 2013.

RESULTS

Adequate data was available to identify pooled incidence rates from seven articles. The pooled relative risk derived from 591 patients was 0.63 (95% CI: 0.47 to 0.85), indicating that patients who have flap reconstruction/reinforcement reduced their risk of PCF by one-third.

CONCLUSION

This pooled analysis suggests that there is a clear advantage in using vascularized tissue from outside the radiation field in the laryngectomy defect. While some studies show a clear reduction in PCF rates, others suggest that the fistulae that occur are smaller and rarely need repair.

Predictors of Salivary Fistulas in Patients Undergoing Salvage Total Laryngectomy

Background. Salivary fistula is a common complication after salvage total laryngectomy. Previous studies have not considered the number of layers of pharyngeal closure and have not classified fistulas according to severity. Our objective was to analyze our institutional experience with salvage total laryngectomy, categorize salivary fistulas based on severity, and study the effect of various pharyngeal closure techniques on fistula incidence. Methods. Retrospective analysis of 48 patients who underwent salvage total laryngectomy, comparing pharyngeal closure technique and use of a pectoralis major flap with regard to salivary fistula rate. Fistulas were categorized into major and minor fistulas based on whether operative intervention was required. Results. The major fistula rate was 18.8% (9/48) and the minor fistula rate was 29.2% (14/48). The overall (major plus minor) fistula rate was 47.9%. The overall fistula and major fistula rates decreased with increasing the number of closure layers and with use of a pectoralis major flap; however, these correlations did not reach statistical significance. Other than age, there were no clinicopathologic variables associated with salivary fistulas. Conclusion. For salvage total laryngectomies, increasing the number of closure layers or use of a pectoralis major flap may reduce the risk of salivary fistula.

A comparison between free gracilis muscle flap and pedicled pectoralis major flap reconstructions following salvage laryngectomy

INTRODUCTION

Muscle flaps are often used in the prevention and treatment of pharyngocutaneous fistula following total salvage laryngectomy in the setting of chemo-radiated neck for laryngeal carcinomas. We report our experience with the gracilis free muscle flap compared to the pedicled pectoralis major for the prophylaxis of fistula formation.

METHODS

Forty-nine patients with radio-recurrent laryngeal carcinoma over ten years who underwent salvage laryngectomy and either immediate free gracilis (22 patients) or pedicled pectoralis major muscle flap (27 patients) reconstruction were reviewed.

RESULTS

There were 12 complications in pectoralis major flap group and eight in gracilis flap group. Most of these occurred early in the post-operative period. These were related to poor wound healing with the pectoralis major flap reconstructions. Fistulation rates were similar in the two groups (Pectoralis major: 6/27, gracilis: 5/22).

CONCLUSIONS

In our experience, the gracilis free muscle flap is a good reconstructive option in the prevention of pharyngocutaneous fistula formation following salvage laryngectomies. It is at least equivalent to a pectoralis muscle flap in the prevention of fistulae, but we prefer the gracilis for many reasons, including ease of harvest and preservation of the pectoralis major flap for future reconstructions.

The role of pectoralis major myofascial flap in salvage laryngectomy: a single surgeon experience

CONCLUSIONS

These results support the use of a pectoralis major myofascial flap (PMMF) in patients undergoing salvage surgery.

BACKGROUND

Pharyngocutaneous fistula (PCF) is the most common major complication following laryngectomy. Preceding chemoradiotherapy increases the incidence and severity of PCF formation. The aim of this study was to determine whether the use of a PMMF reduces the incidence and severity of PCF formation in patients undergoing salvage surgery.

METHODS

This was a retrospective cohort analysis.

RESULTS

A total of 33 patients were identified, including 10 patients who underwent salvage surgery after chemoradiotherapy. In all, 80% of salvage surgery patients underwent PMMF reinforcement of the pharyngeal closure. A PCF rate of 50% was recorded for salvage surgery patients without PMMF reinforcement. Identical PCF rates (25%) were recorded for patients who underwent primary total laryngectomy and salvage surgery patients treated with PMMF reinforcement. Mean duration to fistula closure was 57.16 days in the primary laryngectomy group compared with 20.5 days in salvage surgery patients with PMMF reinforcement.

Prevention of wound complications in salvage pharyngolaryngectomy by the use of well-vascularized flaps

CONCLUSIONS

We successfully reduced the incidence of pharyngocutaneous fistulas (PCFs) in high-risk patients undergoing surgery by using pectoralis major myocutaneous flaps (PMMCFs) and deltopectoral flaps (DPFs) to cover suture lines.

OBJECTIVES

We used coverage of suture lines with PMMCFs and DPFs in patients with high risk of PCFs undergoing total laryngectomy (TL) or total pharyngolaryngectomy (TPL) to determine whether coverage of suture lines during salvage surgery can reduce the incidence of PCFs.

METHODS

This retrospective study was based on a review of 52 patients who underwent salvage TL or TPL between 2001 and 2011; we have been using PMMCFs or DPFs during salvage surgery since 2008. Details of postoperative complications including PCFs were analyzed.

RESULTS

The incidence rate of PCF was lower in the flap group (7.7%) than that in the non-flap group (30.1%). No carotid ruptures were observed in the flap group (0%) as contrasted with patients in the non-flap group (7.7%).

[Pharyngocutaneous fistula as a complication after total laryngectomy--clinical study and literature review]

Pharyngocutaneous fistula is an important therapeutic problem. It occurs in approximately 20% of cases as a complication after total laryngectomy, performed due to the larynx and/or hypopharynx cancer. The process of fistulas' conservative treatment is very long and sometimes reconstructive surgery of the pharynx and esophagus is necessary. Clinically, it is desirable to isolate a group of patients with risk factors of this complication. Numerous pathologies implicated in fistula formation are mentioned in the literature: wound infection, radiotherapy prior to surgery, hypoalbuminaemia, concomitant general diseases, postoperative anemia, location of the cancer in larynx and many others.

OBJECTIVE

This paper analyzes the incidence and etiology of cutaneous fistulas after total laryngectomies as well as overall characterization of risk factors on the basis of the material collected by the Department of Otolaryngology Medical University of Warsaw between the years 2006-2011. Furthermore, an analysis of the literature on cutaneous fistula after total laryngectomy of the last 10 years was performed.

MATERIAL AND METHODS

A retrospective analysis of medical records of patients with laryngeal and hypopharyngeal cancer, treated with total laryngectomy was performed. 12 patients developed cutaneous fistula in the early postoperative period.

RESULTS

The mean time of appearance of fistula after total laryngectomy was 19.3 days. In most cases, conservative management was used to obtain fistulas' closure - after an average of 32.5 days. For two patients operative closure was needed. Microbiological study confirmed the infection in the region of the fistula in 10 patients. There were identified different pathogens, both aerobic and anaerobic bacteria and fungi. 3 patients with a fistula were preoperatively irradiated. The most common location of the cancer in this group was supraglottic area and piriform recessus (8/12 patients).

CONCLUSIONS

The pathogenesis of cutaneous fistula as a complication after total laryngectomy seems to be complex. The most significant risk factors for fistula formation are: radiotherapy, supraglottic location of the tumor, extension of the surgery to the pharynx and malnutrition of the patient. Postoperative wound infection favors the formation of fistulas and extends their healing time. It seems reasonable to plan the surgery with the reconstruction of the pharynx for patients with several risk factors of fistulas' onset.

Multivariate analysis of wound complications after surgery for laryngeal and hypopharyngeal cancers

PURPOSE

The aim of this study was to identify the factors leading to postoperative complications following surgical management of laryngeal and hypopharyngeal cancers.

PROCEDURES

Between 2001 and 2008, the medical records of 107 laryngeal and hypopharyngeal cancer patients requiring laryngectomy or pharyngolaryngectomy at our hospital were reviewed. The incidence of wound complications and correlation of complications with clinicopathological factors were investigated by univariate and multivariate analysis.

RESULTS

The overall incidence of wound complication was 33.6%. The complication incidence was 35.2, 21.7 and 46.2% for the primary surgery, radiation and chemoradiation groups, respectively. Diabetes mellitus and bilateral paratracheal node dissection were significantly correlated and were independent risk factors according to multivariate analysis. Bleeding from a large vessel occurred in 4 patients, and there were significant correlations with chemoradiation.

CONCLUSION

Preoperative chemoradiation was not a significant risk factor for wound complication in this study. However, once postoperative wound complications occurred, they tended to produce lethal outcomes.

The pectoralis major myocutaneous flap revisited: a reliable technique for head and neck reconstruction

The pectoralis major myocutaneous flap (PMMF) remains a useful flap for head and neck reconstruction. Although free-tissue transfer is often preferred, the benefits of the PMMF should not be overlooked. A retrospective chart review was performed on all PMMFs used at Emory for head and neck reconstruction from 1992 through 2008. A total of 139 PMMF were performed in 136 patients with an average age of 65 years. Eighty-six patients were males. All patients except one had a history of Head and Neck Cancer. A smoking history was present in 92% of the patients. Defect location included oral cavity (n = 59), pharyngeal/fistulae (n = 48), temporal bone and cheek (n = 24), oropharyngeal (n = 4), and esophageal (n = 2). The PMMF was used in 4 occasions as a salvage procedure. The survival of the flap was 99.2% (138/139). The PMMF provided definitive closure of the defect in 100% of the cases. The overall average follow-up was 10.5 months. Eighteen patients (13%) developed complications after the procedure. Patients who had radiation therapy had significantly higher complication rates. The PMMF flap remains a very versatile technique with proven reliability for soft tissue coverage of many head and neck defects.

Pectoralis myofascial flap during salvage laryngectomy prevents pharyngocutaneous fistula

OBJECTIVE

To determine the rate of pharyngocutaneous fistula after salvage laryngectomy and assess if pectoralis myofascial flap reinforcement over primary pharyngeal closure prevents pharyngocutaneous fistula.

STUDY DESIGN

Case series with chart review.

SETTING

Tertiary-care public hospital.

SUBJECTS AND METHODS

This study included 43 patients undergoing total laryngectomy between 2003 and 2008. Pectoralis myofascial flap reinforcement of the pharyngeal closure during salvage laryngectomy was performed on patients after June 2006. The main outcome measure was pharyngocutaneous fistula after primary laryngectomy, salvage laryngectomy, and salvage laryngectomy with pectoralis flap reinforcement.

RESULTS

Of the 43 patients, 26 were treated with primary total laryngectomy while 17 received salvage laryngectomy. Seven of 26 patients (27%) undergoing primary total laryngectomy developed pharyngocutaneous fistula. All patients in this group were closed primarily with no flap reinforcement. For salvage laryngectomy, four of seven patients (57%) with primary pharyngeal closure developed pharyngocutaneous fistula; however, none of 10 patients (0%) undergoing salvage laryngectomy with pectoralis myofascial flap reinforcement developed fistula (P<0.02; 0%-23%; 95% CI).

CONCLUSIONS

With pectoralis myofascial flap reinforcement, pharyngocutaneous fistula rate after salvage laryngectomy dropped to 0 percent in this study (0%-23%; 95% CI). This is a simple, reliable technique that prevents postoperative pharyngocutaneous fistula and its associated morbidity after salvage laryngectomy.

Complications with forehead flaps in nasal reconstruction

OBJECTIVES/HYPOTHESIS

To determine what characteristics and comorbidities are associated with a higher rate of complications in patients undergoing nasal reconstruction with a forehead flap.

STUDY DESIGN

Retrospective chart review.

METHODS

Chart review was completed on all patients undergoing nasal reconstruction with forehead flap from 1995 to 2008. Three pre-existing comorbidities were tracked: diabetes, smoking, and vascular disease. Major complications (flap necrosis, nasal obstruction, alar notching) and minor adverse outcomes (partial nasal obstruction, epidermolysis, and alar asymmetry) were recorded.

RESULTS

Two hundred five patients with a median age of 66 years had forehead flap reconstruction between October 1995 and July 2008. Sixty-two patients (30.2%) had full-thickness defects. Forty-eight patients (23.4%) were smokers, 17 (8.3%) were diabetics, and 90 (43.9%) fell into our category of vascular disease. Thirty-three (16.1%) developed a major complication at some point in their postoperative course, with 11 (5.4%) having some degree of flap necrosis, 10 (4.9%) nasal obstruction, and 20 (9.8%) alar notching. Full-thickness defects were significantly associated with higher incidences of any major complication, and had higher odds of flap necrosis and alar notching. Smokers had higher odds of developing flap necrosis. Neither the presence of diabetes, increased age, nor vascular disease was significantly associated with higher rates of major complications.

CONCLUSIONS

Smokers with full-thickness defects are shown to be at greater odds for developing a postoperative complication. Laryngoscope, 2009.
