Pectoralis major musculocutaneous flap in oropharyngeal reconstruction: revisited

FAMM flap in oral cavity and tongue defect reconstruction: A systematic review and meta-analysis

BACKGROUND

The facial artery musculomucosal (FAMM) flap is a versatile flap based on the facial artery. It can be used to reconstruct the floor of the mouth, palate, tongue and alveolar ridge. The flap can be designed in various orientations and modified as an islanded or tunnelised flap. This study aimed to review the application of FAMM flap in the reconstruction of defects of the tongue and oral cavity, with specific focus on success rates and total complications.

METHODS

A literature search was conducted by 2 independent reviewers on PubMed, Dynamed, DARE, EMBASE, Cochrane and British Medical Journal (BMJ) electronic databases (Registry CRD42024529989).

RESULTS

Twenty-seven studies fulfilled the search criteria and data on 407 FAMM flaps performed on 402 patients were extracted for analysis. Overall, 1.7% (n=7) of flaps failed because of total necrosis (n=3), partial necrosis requiring surgical intervention and flap abandonment (n=2), total failure (n=1) and fistula formation (n=1). Overall, 26.0% (n=106) of patients experienced non-functional complications. The most reported complications were partial necrosis (n=23, 5.7%), wound dehiscence (n=18, 4.4%) and venous congestion (n=13, 3.2%). The pooled success rate in all studies using FAMM flaps for oral cavity and tongue reconstruction was 99.47% (95% CI, 98.26 to 100.00, P = 1.00; I2 = 0%;). Pooled total complication rates were 30.18% (95% CI, 16.97 to 43.38, P < 0.01; I2 = 91%). Only 35 flaps required re-operation.

CONCLUSIONS

With low complication and failure rates, FAMM flaps are a safe and versatile option to consider in oral cavity and tongue reconstruction.

Free Flap Reconstruction of the Oropharynx

Reconstruction of the oropharynx plays a critical role in preserving quality of life after surgical resection of oropharyngeal carcinoma. Free tissue is one of several reconstructive options, which can closely approximate native oropharyngeal anatomy and lead to favorable functional outcomes in carefully selected patients. Here, the authors provide an overview of the indications, treatment options, functional outcomes, potential complications, and future considerations for free flap reconstruction of the oropharynx.

Infrahyoid myocutaneous flap for reconstruction in head and neck cancer patients

Background

Reconstruction of head and neck defects following tumor excision is one of the most challenging surgeries due to multiple reasons, such as associated cosmetic and functional impairments. The three-dimensional aspect of the defect makes it more difficult. Although in modern settings, microvascular surgery is preferred in many conditions, it requires the presence of resources and expertise. Locoregional flaps are workhorse flaps in head and neck reconstruction. In this article, we present an uncommonly used flap with high acceptability and success rate in head and neck reconstruction.

Aim

To find outcomes of using infrahyoid flap reconstruction in head and neck defects following cancer excision.

Materials and Methods

The retrospective study was conducted in the surgical oncology department of our institute. Patients with squamous cell carcinoma of the oral cavity, clinically T1-T3 and N0-N1 stage, with anticipated defects of small to medium defects were included in the study. The study was conducted from July 2020 to June 2022, including a follow-up of 1 year. A total of 14 patients were included in the study. All patients had squamous cell carcinoma of the oral cavity involving different subsites. Patients were operated on by a single surgeon, using the same technique.

Result

A total of 14 patients were included with a male-to-female ratio of 11:3 and age between 45 and 60 years. None of the patients underwent revision surgery, and none of the patients had total flap loss. Four patients had minor flap complications, of which three patients had partial, superficial skin necrosis of the flap which was managed conservatively and epithelized later. None of the patients developed major complications, oro-cutaneous fistula, or radiation necrosis. None of the patients developed recurrence after 1 year of surgery.

Conclusion

The infrahyoid myocutaneous flap (IHF) is a fairly reliable and easy-to-perform flap for small- and medium-sized defects of the oral cavity, without requiring additional incisions and donor site reconstruction.

Oropharyngeal reconstruction after transoral robotic surgery

PURPOSE OF REVIEW

Transoral robotic surgery (TORS) has experienced an evolution in recent years. This technique has proved to be a safe and effective method for extirpation of select oropharyngeal tumors. Advances in technology as well as improved surgeon experience allow for the resection of larger, more complex cancers. Although healing by secondary intention remains the current standard for limited oropharyngeal defects, larger resections demand reconstruction with vascularized tissue to minimize morbidity and optimize functional outcomes. The objective of this review is to evaluate recent literature regarding oropharyngeal reconstruction after TORS.

RECENT FINDINGS

A variety of reconstructive options to manage oropharyngeal defects exist. Several reconstructive algorithms have been suggested; however, careful consideration must be used to select the most ideal flap type. Locoregional flaps have shown excellent functional outcomes with limited morbidity. An increase in free flap reconstruction has been demonstrated, particularly among patients with larger TORS defects and following chemoradiation therapy. Despite limited data, robotic-assisted flap inset and microvascular anastomosis has recently shown promise.

SUMMARY

Reconstruction and flap selection following TORS should be tailored to the patient and unique oropharyngeal defect. Functional outcomes are promising with low complication rates among these patients.

Lateral Thoracic Artery Can Stabilize Circulation in the Pectoralis Major Myocutaneous Pedicle Flap: Single-center, Prospective, Uncontrolled Case Series

Background

Head and neck reconstructions using the pectoralis major myocutaneous pedicle flap (PMMF) with thoracoacromial artery alone are prone to hemodynamic instability, possibly leading to infection, prolapse, hematoma, seroma, and partial or total flap failure (6%-71%). Aside from unstable blood circulation, reported risk factors for these complications include feminine gender, smoking, and having diabetes mellitus. Preservation of the lateral thoracic artery in addition to the thoracoacromial artery has been suggested as a way to improve unstable blood circulation in the PMMF.

Methods

This is a single-center, prospective, uncontrolled case series. Circulation to the PMMF was studied intraoperatively with and without lateral thoracic artery clamping after harvest. Indocyanine green (ICG) angiopathy, a quantitative hemodynamic assessment method, was used to analyze three parameters: maximum intensity (Imax), time from start of ICG to maximum intensity (Tmax), and slope of intensity (Smax = Imax/Tmax). Hemodynamic parameters, such as pulse rate and blood pressure, were all within normal ranges. Allergy to contrast media was criterion for exclusion.

Results

Six patients all had oral cancer as their primary disease. Their background was characterized by established risk factors: four patients had a history of smoking, two had diabetes mellitus, and two were women. Postoperatively, no patients had complications at the recipient or donor sites. Mean results of the analysis were Imax: 60 ± 47, Tmax: 91 ± 55, Smax: 0.8 ± 0.5 in the clamped group and Imax: 85 ± 40, Tmax: 73 ± 42, Smax: 1.8 ± 1.5 in the un-clamped group. Significant difference was observed in Imax (P = 0.03) and Smax (P = 0.03).

Conclusion

Lateral thoracic artery preservation appears to be useful for stabilizing blood circulation to the PMMF, including in patients considered to be at high-risk for complications, such as women, smokers, and patients with diabetes mellitus.

Contralateral Pectoralis Flap for Repair of Spinal Hardware-Associated Fistula

We report a case of a recurrent hypopharyngeal fistula following spinal hardware placement that required multiple procedures. The course was complicated by a medication error and ultimately the fistula resolved after contralateral pectoralis muscle flap.

Secondary Cervicofacial Soft Tissue Reconstruction With Upper Trapezius Myocutaneous Flap in "Frozen Neck" With Bone Flap and Reconstructive Plate Exposure

ABSTRACT

A frozen neck is a scarred neck with severe fibrosis with a loss of tissue planes secondary to prior irradiation with or without surgery. The purpose of this study was to evaluate the outcomes of cervicofacial reconstruction in patients with soft tissue defects and bone flap and reconstruction plate exposure with the upper trapezius myocutaneous flap. Fifteen oncologic patients with prior surgery and radiotherapy developed soft tissue dehiscence with bone and osteosynthesis material exposure. All patients had either a frozen neck or a vessel-depleted neck. The soft tissue defects were reconstructed, the osteosynthesis material was removed and the bone flap exposure was covered in all patients. One patient developed a seroma and 1 patient reported wound dehiscence. In terms of esthetic results, 6 patients referred a good esthetic result, whereas 8 patients referred a fair result and 1 patient a poor result. Two patients with prior radical neck dissection reported a poor functional result in the ipsilateral shoulder, previously to secondary reconstruction. Functional neck dissection was performed in 10 patients, 8 patients referred a good functional outcome and 2 patients reported a fair result. The upper trapezius flap is an extremely reliable source for secondary cervicofacial soft tissue reconstruction in "frozen neck." In comparison with other locoregional flaps, the upper trapezius flap fulfills all aesthetic and functional criteria for secondary cervicofacial soft tissue reconstruction.

A Modified Design of the Pectoralis Major Myocutaneous Flap for Reconstruction of Head and Neck Defect

ABSTRACT

Even though the pectoralis major myocutaneous flap (PMMF) still has an important role in the free flaps ear, it is reported to have drawbacks such as the limited cephalad extension and high incidence of total or partial flap necrosis. Various modifications have been attempted to augment the limited cephalad extension and a stable blood supply.The aim of this study is to describe a modified design of the skin paddle and preparation of the PMMF, to achieve stable blood circulation and sufficient pedicle length. The priority skin paddle is the medial part for its stable blood supply, and the lateral margin should be adjusted as needed. During the harvesting, the lateral thoracic artery (LTA) is preserved to protect the perforating branches, and the anterior sheath of the rectus abdominis muscle is used as a suture margin to prevent damage of the thin muscle of the PMMF. The skin paddles in this study are larger than those previously reported. All of the 21 patients in our study, the skin paddles show complete survival with no partial necrosis of skin paddle, fistula, or wound dehiscence.It is worthwhile to consider and preserve the LTA as a major contributor to a lateral and distal PMMF. This study would be useful in future and preparation of the PMMF in head and neck reconstruction.

Reconstruction of a Pharyngeal Cutaneous Fistula Using a Bi-Paddled Pectoralis Major Flap for a Patient with a Possibility of Future Postoperative Radiotherapy

BACKGROUND Pharyngocutaneous fistulas are often difficult to treat because pharyngeal contents tend to leak into the cervical layer causing wound infections or abscesses. If reconstruction with free flaps is difficult, pedicled pectoralis major flaps are an option. CASE REPORT A 51-year-old male patient who had undergone radiation and chemotherapy for laryngeal cancer was scheduled for total laryngectomy with combined skin resection for local tumor recurrence. Reconstruction with a left deltopectoral (DP) flap was performed. However, a pharyngocutaneous fistula constructed due to cervical soft-tissue infection required reconstruction using a right bi-paddled pectoralis major muscle. The anterior pharyngeal wall was reconstructed with the medial skin island, and the lateral skin island was folded back to reconstruct the soft tissues. Since this was the patient's third recurrence, the possibility of subsequent local recurrences, and hence of the need for radiation therapy, were high. In such cases, the pedicle of the pectoralis major muscle flap is normally closed using a DP flap. However, in the present case, the DP flap had already been used on both sides. We therefore utilized a right bi-paddled pectoralis major flap for cervical reconstruction. CONCLUSIONS We successfully reconstructed the cervical skin and soft tissue thickly, and primarily-closed the donor site, by creating a second skin island from surplus areas of the existing skin island. This method is particularly useful for the reconstruction of cervical skin and soft tissues due to the possible need for future radiation therapy, when the use of free flaps and DP flap is unfeasible.

A decade of reconstructive surgery: outcome and perspectives of free tissue transfer in the head and neck. Experience of a single center institution

PURPOSE

Free flaps have become the standard option in reconstructive surgery of the head and neck. Even though many authors have outlined the reliability of free transplants, there is an ongoing discussion about treatment options for patients bearing particular risks as previous irradiation treatment. In this analysis, we aim to address these patients with particular risk profiles by comparing different flap entity outcome parameters.

METHODS

We retrospectively analyzed a cohort of 494 patients who underwent flap surgery between 2009 and 2018 in our department. Focusing on free microvascular transplants, we additionally analyzed the pectoralis major myocutaneous flap as the most frequently used vascular pedicled flap. Data analysis was performed by uni- and multivariate statistics.

RESULTS

Overall flap success rate was 90%, with the radial forearm flap occurring to be most reliable (93%) in head and neck reconstruction. Previous radiation therapy (RT) and intraoperative revision of vascular anastomosis during primary surgery significantly resulted in impaired transplant outcome with a success rate of 91.8% (no RT) vs. 83.7% (RT), respectively. There was a negative linear correlation between incision to suture time and number of flaps per year (R² = 0.67).

CONCLUSIONS

Preoperative radiation therapy and intraoperative revision of anastomosis significantly impair outcome of microvascular flaps in the head and neck and oral cavity, whereas patient's age is not a predictor of flap failure. Increasing case number and experience reduces time of flap surgery as well as rate of complications and flap failure.

Effectiveness of pectoralis major myocutaneous flap in the surgical management of oral cancer: A retrospective study

INTRODUCTION

Over 80,000 oral cancer cases get diagnosed each year in India, majority undergoing extensive resections owing to their late presentation. Pectoralis major myocutaneous (PMMC) flap is a pedicled axial pattern flap which is based on thoracoacromical artery. It is readily available as a viable alternative to free flap reconstruction, especially for the economically poor and malnourished patients. Its proximity to head and neck structures gives added advantage to reconstruct complex and large volume oral and maxillofacial defects. It provides a relatively good possibility of functional and aesthetic restoration providing both mucosal lining and skin cover.

MATERIALS AND METHODS

This was a prospective observational study of 29 PMMC flap reconstructions, conducted between 2013-2016. The reconstruction outcomes assessed in this study were divided into two categories namely "success" and "failure" based on certain functional parameters observed during follow-up of 1 year. The complications were broadly classified as major/minor and flap related/non-flap related. We assessed the feasibility of using a PMMC flap for reconstructing various subsites of oral cavity cancer. Further, the association of patient variables with complication rates and outcome of reconstruction were analysed.

RESULTS

Out of 29 patients overall complications were noted in 15 (51.7%) cases with a female preponderance. Flap-related complications were noted in 9 whereas non-flap-related complications were seen in 6 patients. Major and minor complications were noted in 2 (both flap related) and 13 cases respectively. Complete full thickness flap necrosis was not encountered in any patient. Patients with flap skin paddle size ≤ 36 cm² (n = 12) had significantly increased overall complication rates. Despite complications a high success rate (93.1%, n = 27) was achieved with this mode of reconstruction.

CONCLUSION

The PMMC flap reconstruction is a versatile, reliable and an affordable single staged procedure with a high success rate in terms of achieving treatment goals. Although it has moderately high complication rates, but PMMC flap proved to be a workhorse in locally advanced cases of head and neck cancer at the end of 1 year follow-up.

Comparison of outcomes with extensive segmental pectoralis major myocutaneous flap via the anterior axillary line and the conventional technique in oral and oropharyngeal cancer

BACKGROUND

This study compared the outcomes of an extensive segmental pectoralis major myocutaneous flap (esPMMF) and a conventional pectoralis major myocutaneous flap (PMMF).

METHODS

The study enrolled 91 patients with primary oral and oropharyngeal squamous cell carcinoma (SCC) who underwent radical resection followed by reconstruction of the defect using either an esPMMF via the anterior axillary line or a PMMF. The pedicle lengths of the esPMMF and PMMF were 22-28 and 18-22 cm, respectively. The esPMMF and PMMF had skin paddle dimensions of 5 × 8 to 7 × 14 cm and 6 × 7 to 8 × 17 cm, respectively.

RESULTS

The esPMMF pedicle was longer than that of the PMMF. The range of shoulder abduction was significantly greater in the esPMMF group and the donor-site aesthetic results were better.

CONCLUSION

The esPMMF has a longer pedicle flap, enables a greater range of shoulder abduction, and has a better aesthetic result than the conventional technique.

Infrahyoid flap in oropharyngeal reconstruction following carcinoma resection: A study of 6 patients and literature review

The present study aimed to describe the techniques used and the results obtained with the infrahyoid flap for the reconstruction of medium-sized oropharyngeal defects following resection for advanced squamous cell cancer. During a period of 1 year, six patients with oropharyngeal defects were reconstructed using the infrahyoid flap. The tumor characteristics, location and size of the defect, resective and reconstructive techniques employed and the complications and outcomes of the speech and swallowing functions, as identified in the follow-up visits every 3 months, were evaluated. All flaps were performed simultaneously in association with tumoral excision and ipsilateral supraomohyoid neck dissection. The mean size of the skin paddle was 7.0×3.5 cm. The donor site was primarily sutured. The postoperative course was uneventful and all flaps were viable. One case of marginal skin paddle loss occurred without affecting the survival of the flap. Five patients received postoperative radiotherapy and one patient received concurrent postoperative chemotherapy. During the follow-up period (mean, 63 months), all patients showed excellent oral swallowing. Speech was excellent in five patients and in one patient speech was classified as good. The aesthetic results of the cervical donor site were good. Based on the present case report and the literature review, the infrahyoid flap is a simple and safe procedure for the reconstruction of the oropharynx, with a high success rate, minimal donor site morbidity and good aesthetic and functional results. The infrahyoid flap is a valid surgical option that may be considered in selected oncological patients undergoing reconstruction of medium-size oropharyngeal defects.

Predictive factors of dysphagia after lateral and superior oropharyngeal reconstruction with free flap transfer

BACKGROUND AND OBJECTIVES

Lateral and superior oropharyngeal reconstruction is technically challenging and can be complicated by postoperative dysphagia. The aim of this retrospective study was to identify the predictive factors of dysphagia after lateral and superior oropharyngeal reconstruction with free flap transfer and to establish better management for cases with these predictive factors.

METHODS

We performed a retrospective chart review of 109 patients who had undergone lateral and superior oropharyngeal reconstruction with free flap transfer for oropharyngeal cancer. Preoperative, operative, and postoperative variables were examined, and possible predicative factors for dysphagia were subjected to univariate analysis and multivariate logistic regression analysis.

RESULTS

Dysphagia occurred in 16 patients (14.7%). Multivariate logistic regression analysis identified extensive tongue base resection, postoperative radiotherapy, and history of radiotherapy to the head and neck region as independent factors contributing to dysphagia after lateral and superior oropharyngeal reconstruction. Of these factors, extensive tongue base resection was the most important.

CONCLUSIONS

Early intervention to minimize the risk of dysphagia should be performed for patients identified with these predictive factors.

Regional Myocutaneous Flaps for Head and Neck Reconstruction: Experience of a Head and Neck Cancer Unit

Background:

Pectoralis major myocutaneous pedicle flap and other regional myocutaneous pedicle flaps (RMF), despite the superiority shown by free flaps, have remained relevant in the reconstruction of major head and neck oncologic defects. It has continued to find relevance as the preferred reconstruction of choice in some general head and neck reconstructive applications. While its role has been defined in developed environment, the same cannot be said for developing environment. The aim thus, was to review our experiences with RMFs in head and neck reconstructions, with a view to evaluating the indications and outcomes in a limited opportunity environment with some free flaps expertise.

Materials and Methods:

This was a retrospective cohort study from records of RMF cases performed for head and neck reconstruction, at the study institution. Eligibility for study inclusion comprised case cohorts with advanced head and neck diseases requiring ablative surgery and reconstruction with pectoralis major flaps and other RMFs.

Results:

A total of 17 cases were treated with RMFs. 10 were pectoralis major flaps while 7 were other RMFs. The main indications were failed free flaps and financial constraints. No regional pedicle flap failure was recorded; however, complication rate was 35.5% (6/17).

Conclusion:

Pectoralis major flaps and other RMFs were very reliable option for head and neck reconstruction. Free flap failure and financial constraints were the main indications for RMF reconstruction indications in head and neck reconstruction in a developing environment with some free flap expertise.

Extended vertical lower trapezius island myocutaneous flap versus pectoralis major myocutaneous flap for reconstruction in recurrent oral and oropharyngeal cancer

BACKGROUND

The purpose of this study was to compare the use of an extended vertical lower trapezius island myocutaneous flap (TIMF) and a pectoralis major myocutaneous flap (PMMF).

METHODS

A total of 39 patients with advanced recurrent oral and oropharyngeal squamous cell carcinoma (SCC) underwent salvage surgery followed by placement of either an extended lower vertical TIMF or PMMF for reconstruction. Twenty-one patients received extended lower vertical TIMFs, whereas 18 received PMMFs.

RESULTS

The pedicle length of the TIMF was longer than that of the PMMF, and the skin paddle of the TIMF was both wider and longer than the PMMF. No major complication developed in any of the patients. The TIMF group experienced a lower rate of minor flap failure than did the PMMF group.

CONCLUSION

Use of an extended vertical lower TIMF, which has a longer pedicle flap and a larger skin paddle than a PMMF, is optimal for reconstruction of major defects. © 2015 Wiley Periodicals, Inc. Head Neck 38: E159-E164, 2016.

Esophagus and hypopharyngeal reconstruction

This article reviews the literature on esophageal reconstruction. The most common methods used are gastric pull-up, pectoralis major flap, colon interposition, fasciocutaneous flaps (radial forearm free flap or anterolateral thigh flap), and free jejunum and colon flaps. The stricture rates, fistula rates, morbidity, and mortality of each flap are reviewed.

Salvage for pectoralis major myocutaneous flap failure in head and neck reconstruction by microvascular flap

The pectoralis major myocutaneous pedicled flap (PMMPF) - the "workhorse" for head and neck reconstruction - is associated with a high incidence of complications in certain cases. This study presents free tissue transfer as an alternative salvage technique after PMMPF failure in head and neck reconstruction. It includes seven consecutive patients who underwent free tissue salvage after PMMPF failure in head and neck reconstruction from January 2008 to September 2010 at Kaohsiung Medical University Hospital, Taiwan. Four vertical rectus abdominis myocutaneous (VRAM) flaps were applied for tongue and mouth floor defects, while three anterolateral thigh (ALT) flaps were used for mouth floor, buccal, and cheek defects. All flaps survived uneventfully, and normal oral feeding was achieved without major complications. Free tissue transfer has several advantages and can be successfully employed in head and neck reconstruction, and it is also a reliable salvage procedure after PMMPF failure in such cases.

Analysis of 120 pectoralis major flaps for head and neck reconstruction

BACKGROUND

A pectoralis major flap is one of the standard tools for the reconstruction of defects of the head and neck. Despite the technical advancement in free tissue transfer in head and neck reconstruction, the benefits of a pectoralis major flap should not be overlooked. The purpose of this study is to evaluate our 17 years of experience in reconstructing defects of the head and neck region using the pectoralis major flap.

METHODS

We retrospectively reviewed the medical records of 112 patients (120 cases) who underwent pectoralis major flap operations for head and neck reconstruction during a period ranging from 1994 to 2010.

RESULTS

In our series, no total necrosis of the flap occurred. Of the total cases, 30.8% presented with flap-related complications. Major complications occurred in 20% of all of the cases but were then all successfully treated. The male sex was correlated with the occurrence of overall complications (P=0.020) and major complications (P=0.007). Preoperative albumin levels of <3.8 g/dL were correlated with the formation of fistula (P=0.030). Defects of the hypopharynx were correlated with the occurrence of major complications (P=0.019) and the formation of fistula (P=0.012). Secondary reconstructions were correlated with the occurrence of overall complications (P=0.013) and the formation of fistula (P=0.030).

CONCLUSIONS

A pectoralis major flap is still considered to be a safe, versatile one-stage reconstruction procedure in the management of the defects of head and neck and the protection of the carotid artery.

Pectoralis major flap for head and neck reconstruction in era of free flaps

The aim of this study was to evaluate factors affecting the selection of pectoralis major flap in the era of free tissue reconstruction for post ablative head and neck defects and flap associated complications. The records of patients who underwent various reconstructive procedures between July 2009 and December 2010 were retrospectively analysed. 147 reconstructive procedures including 79 free flaps and 58 pectoralis major flaps were performed. Pectoralis major flap was selected for reconstruction in 21 patients (36%) due to resource constrains, in 12 (20%) patients for associated medical comorbidities, in 11 (19%) undergoing extended/salvage neck dissections, and in 5 patients with vessel depleted neck and free flap failure salvage surgery. None of the flaps was lost, 41% of patients had flap related complications. Most complications were self-limiting and were managed conservatively. Data from this study suggest that pectoralis major flap is a reliable option for head and neck reconstruction and has a major role even in this era of free flaps. The selection of pectoralis major flap over free flap was influenced by patient factors in most cases. Resource constraints remain a major deciding factor in a developing country setting.

Clinical outcome of reconstruction of the lateral oropharyngeal wall with an anterolateral thigh free flap

The anterolateral thigh (ALT) free flap is widely used for various reconstructions in the head and neck. However, its use in the oropharynx has not been widely evaluated, so we have reviewed our experience. We retrospectively reviewed the medical records of 28 patients with oropharyngeal cancer, who were treated with immediate reconstruction with an ALT free flap after excision. We recorded history, stage of tumour, course of operation, postoperative period, oncological treatment, clinical outcome, and follow-up. The mean age of the patients was 61 years (range 44-83). Ten of the patients had clinically relevant coexisting conditions. Most of the patients had T3-4 tumours and involved neck nodes. The operations included resection of the tumour, neck dissection, and reconstruction of the oropharynx with an ALT free flap. All donor sites were closed primarily. Eight patients (29%) developed early local complications that required reoperation. Ten patients (36%) had postoperative cardiopulmonary problems. Twenty-seven flaps succeeded; one was lost. There were no other complications or late problems of the donor site except one seroma. Twenty-one patients were given postoperative radiotherapy. After the mean follow-up period of 40 months (range 13-68) 20 patients (71%) were disease-free. Three patients required a permanent gastrostomy and one a permanent tracheostomy. We conclude that the ALT free flap can be used successfully for reconstruction of a lateral oropharyngeal defect with manageable postoperative morbidity.

Pectoralis major myocutaneous flaps for head and neck reconstruction: factors influencing occurrences of complications and the final outcome

CONTEXT AND OBJECTIVE

Pedicled flaps play an important role in cancer treatment centers, particularly in developing and emerging countries. The aim of this study was to identify factors that may cause complications and influence the final result from reconstructions using pectoralis major myocutaneous flaps (PMMFs) for head and neck defect repair following cancer resection.

DESIGN AND SETTING

Cross-sectional study at the Hospital de Ensino Padre Anchieta of Faculdade de Medicina do ABC (FMABC).

METHODS

Data on 58 patients who underwent head and neck defect reconstruction using PMMFs were reviewed. The final result from the reconstruction (success or failure) and the complications observed were evaluated in relation to the patients' ages, area reconstructed, disease stage, previous oncological treatment and need for blood transfusion.

RESULTS

There were no total flap losses. The reconstruction success rate was 93.1%. Flap-related complications occurred in 43.1% of the cases, and half of them were considered major. Most of the complications were successfully treated. Defects originating in the hypopharynx were correlated with the development of major complications (p = 0.02) and with reconstruction failure (p < 0.001). Previous oncological treatment negatively influenced the reconstruction success (p = 0.04).

CONCLUSIONS

Since the risk factors for developing major complications and reconstruction failure are known, it is important to heed the technical details and provide careful clinical support for patients in a more critical condition, so that better results from using PMMFs can be obtained.

Transaxillary-subclavian transfer of pedicled latissimus dorsi musculocutaneous flap to head and neck region

Free-tissue transfer is the reconstruction of choice for most head and neck defects. However, pedicled flaps are also used, especially in high-risk patients and after failure of a free flap. The aim of this study was to compare transaxillary-subclavian pedicled latissimus dorsi musculocutaneous (PLDMC) flap, pectoralis major musculocutaneous flap, and free-tissue transfer for head and neck reconstruction in American Society of Anesthesiologists grades II and III patients. During the last 4 years, PLDMC flap with a modified transaxillary-subclavian route for transfer to the neck was used in 8 patients, pectoralis major musculocutaneous flap was used in 7 patients, and free flaps were used in 12 patients for head and neck reconstructions. These 3 methods were compared regarding the flap dimensions, complications, flap outcome scores, hospitalization time, and cost of the treatment. Mean age of the patients, mean American Society of Anesthesiologists scores, mean dimensions of the flaps, and mean hospitalization time did not differ significantly among the 3 groups. Regarding the operation time, flap complications, outcomes, and cost of total treatment, although statistically not significant, PLDMC group offered the fastest reconstruction with highest flap outcome scores and minimum cost. Free-tissue transfer is the procedure of choice especially for functional reconstruction of head and neck region. Occasionally, there exist cases in whom a pedicled flap could offer a safer option. The PLDMC flap transferred via the transaxillary-subclavian route may be preferred than, with advantages including increased arc of rotation, safer pedicle location, shorter duration of the procedure, and reduced complication rates and costs.

Reconstruction of the esophagus and voice

BACKGROUND

Esophageal defects are reconstructed using a variety of methods and tissue types. The choice depends on the location of the defect, the condition of the patient, and the flaps that are available for reconstruction. Often, patients with esophageal defects also lack a mechanism for voice production following a total laryngectomy procedure.

METHODS

A review of the literature was performed for esophagus reconstruction and voice rehabilitation following laryngectomy. Methods of voice restoration using intestinal transfers are presented based on the authors' experience.

RESULTS

Several methods of esophagus and voice restoration can achieve excellent functional outcomes.

CONCLUSION

Esophagus reconstruction and voice rehabilitation following esophageal resection and total laryngectomy are possible using a variety of flaps with good functional outcomes.

Free tissue transfer versus pedicled flap reconstruction of head and neck malignancy defects

BACKGROUND

With the advent of microsurgery the pedicled flap is considered by many to be an outdated surgical option.

AIMS

To explore the relationship between flap survival and pre-morbid risk factors, conduct a comparative analysis of flap and systemic morbidities and complete a cosmesis and functionality assessment for oral and oropharyngeal reconstruction patients.

METHODS

114 patients, over a 13-year period, who had a one-stage reconstructive procedure employing the pectoralis major myocutaneous flap (PMMF) or radial forearm-free flap (RFFF).

RESULTS

Variables, including age, smoking and radiation exposure were not statistically significant predictors of flap survival probability. Atelectasis was a significant post-op finding of RFFF patients. Flap dehiscence of >50% was a significant morbidity of PMMF. No statistical difference in cosmetic deformity, diet and socialisation was noted.

CONCLUSIONS

Pectoralis major myocutaneous flap remains an enduring and safe flap; however, the RFFF has markedly improved speech performance over the PMMF.

[Applicable methods of reconstruction for the replacement of soft tissue after the radical resection of oral tumors]

In Hungary the number of oral and pharyngeal cancers is alarmingly high. While the mortality rate in 1955 was 282, by 2005 it rose to 1567. However, in the last 1-2 years stagnation can be observed. Nevertheless, even now significant proportions of men and women are involved. Alcohol consumption and smoking are invariably the leading causes, but one cannot disregard the shortcomings of oral cancer screenings, either. Unfortunately, drastic changes in this field are not likely to occur in the near future. Numerous solutions have been developed for the replacement of soft tissue. In our article, we describe and evaluate four of them. When using these techniques, we were often successful in replacing soft tissue deficiencies.

Tongue reconstruction: recent advances

PURPOSE OF REVIEW

To examine the recent literature concerning advances in tongue reconstruction after tumor resection.

RECENT FINDINGS

Reconstruction following resection of malignant tongue tumors remains one of the most difficult problems in head and neck oncology. Recent trends in tongue reconstruction have focused on optimizing speech and swallowing function and maximizing quality of life. In the recent literature, several new reconstructive strategies including omohyoid musculocutaneous and myofascial flaps overlayed with radial forearm free flaps have been described. In addition, several older reconstructive options, such as trapezius and pectoralis rotational flaps, have been revisited. There has also been a trend toward restoring innervation to these flaps rather than leaving them insensate.

SUMMARY

Tongue cancer resection and subsequent reconstruction pose interesting challenges to the surgeon to maximize postoperative function and quality of life. Attention to the principles of tongue reconstruction and knowledge of the range of available reconstructive options can result in more favorable functional outcomes.
