Supraclavicular artery island flap in head and neck reconstruction

The Versatility of the Supraclavicular Flap for Head and Neck Reconstruction

Study Design

Descriptive study of 17 patients with primary or secondary reconstruction using a supraclavicular flap.

Objective

Describe the different options for primary and secondary reconstruction using the supraclavicular flap, as well as the complications that may arise.

Methods

The present study analyzed the outcomes of 17 patients who underwent reconstruction using the supraclavicular artery island flap at the Maxillofacial Department of Hospital Universitario Virgen de las Nieves (Granada, Spain) from November 2017 to June 2023.

Results

The SCAIF served as the primary reconstructive option in 9 cases, covering skin defects in the parotid region (4 patients), cervical area (1 patient), partial tongue defects (3 patients), and cheek defects (1 patient). Additionally, the flap was used as a secondary reconstructive option in 8 patients affected by osteoradionecrosis (ORN) with bone and plate exposure. Complications included a single case of shoulder joint septic arthritis and 3 patients who experienced cervical fistula and neck infection.

Conclusions

The supraclavicular flap represents a highly effective option for oncological reconstruction within the head and neck region. This flap is particularly useful in patients with significant clinical concerns and contraindications, both local and systemic, for microsurgical free flap procedures due to its reliability, versatility, and safety.

Versatility of the supraclavicular artery island flap for head and neck reconstruction

Objective

To present our experience using the supraclavicular artery island flap (SCAIF) for head and neck reconstruction.

Methods

We performed a retrospective chart review to identify patients who underwent head and neck reconstruction with SCAIF at our institution. The following data were collected: age, sex, surgical indications, flap harvest time, flap dimensions, length of hospital stay, complications, and clinical outcomes.

Results

Thirty-three patients underwent SCAIF reconstruction, of whom four underwent pectoralis major myocutaneous flap reconstruction simultaneously. Twenty flaps were used to repair pharyngeal or esophageal defects following resection for tonsillar, hypopharyngeal, laryngeal, and cervical esophageal cancers. Five flaps were used for tracheal reconstruction following resection for tracheal or thyroid gland cancer. Seven flaps were used for reconstruction of cervical skin defects or fistulas related to a previous treatment. One flap for tracheal stenosis following tracheotomy. The mean age of the patients was 60.69 ± 11.47 years. The mean flap harvest time was 32.00 ± 4.44 min. The mean flap size was 10.16 ± 3.91 × 5.78 ± 0.68 cm. The mean length of hospital stay is 24.84 ± 13.78 days. Three patients had partial necrosis of the distal portion of the flap, which resolved with anti-infection therapy and local wound care. One patient developed a fistula that was resolved with wound care and further surgical intervention. Complete flap loss or major complications were not observed. No donor site complication or compromised shoulder function was observed.

Conclusion

The SCAIF can be successfully used to reconstruct head and neck defects with good outcomes and limited morbidity.

Application of supraclavicular island flap in oral and maxillofacial reconstruction

Several surgical modalities are available for maxillofacial reconstruction as locoregional or microvascular free flaps.

PURPOSE

(a) Evaluate the reliability of the supraclavicular flap in cervico-orofacial region; (b) investigate the role of computed tomography angiography (CTA) in predicting the post-operative viability of the flap; (c) assess the speech, feeding, and esthetics after reconstruction using this flap.

METHODS

Eleven patients included in this study underwent either conventional or delayed harvesting of the supraclavicular flap (SCF). All the patients had diagnostic computed tomography angiography (CTA) of the supraclavicular flap before the surgery.

RESULTS

The mean harvesting time of the flap was 45.45 ± 4.16 min. The average length of the flap was 22.64 ± 1.12 cm, whereas the mean width of the flap was 6.14 ± 1.14 cm. The flap survived in 9 patients, while two patients had complete flap loss. After the surgery, three patients complained of speech difficulties. Two patients had swallowing problems. After the surgery, three patients complained of speech difficulties. Two patients had swallowing problems. Only two patients complained of weakness in the donor site. None of the patients reported that the weakness or pain at the donor site affected their daily activities or quality of life.

CONCLUSION

The pedicled SCF represents a safe and feasible option that can be used to reconstruct a wide array of maxillofacial oncologic defects. However, a study with a larger sample size is recommended to achieve more reliable clinical results for the modified delayed technique modification in terms of their effect on the survival of the supraclavicular flap.

Supraclavicular Artery Island Flap for Treatment of Cervical Wound Defects and Persistent Cerebrospinal Fluid Leaks: A Technical Note and Systematic Review of the Literature

BACKGROUND

Soft tissue defects and persistent cerebrospinal fluid (CSF) leaks can create complications after cervical spinal surgery. The supraclavicular artery island (SAI) flap is useful in closing tissue defects, particularly in these complex surgeries and multiple reinterventions. However, technical reports in this context are scarce. We describe application of the SAI flap technique to control persistent CSF leak in the first documented instance (to our knowledge) of a low-grade fibromyxoid sarcoma (LGFMS) in the cervical epidural space. Additionally, we conducted a comprehensive review of PubMed, Embase, and Google Scholar from their earliest records through December 17, 2023 using combined terms, "supraclavicular artery island flap AND spine" and "supraclavicular AND flap AND spine".

TECHNICAL NOTE

A 56-year-old woman with arm pain and weakness presented with a cervical epidural mass extending from C4-C6 and associated spinal cord compression. She underwent a 3-level corpectomy and tumor resection. Primary dural closure was impossible due to the dural invasion, and reintervention with an SAI flap and definitive lumboperitoneal shunting were required to control and seal the CSF leak.

SYSTEMATIC LITERATURE REVIEW

Seven case reports describing SAI flap for spinal surgery complications were identified. The indications in those cases were correcting esophageal and hypopharyngeal perforations after cervical fusion and discectomy and persistent soft tissue coverage after cervical instrumentation.

CONCLUSIONS

The SAI flap technique provided wound defect coverage in this case and is suitable for addressing issues such as persistent CSF leaks or soft tissue coverage after cervical spine surgery.

Clinical Analysis of Supraclavicular Flaps for the Repair of the Pharyngeal Fistula

Objectives: We explored the value of supraclavicular flaps in repairing pharyngeal fistula. Methods: Patients treated with supraclavicular flaps were included. Data on preoperative radiotherapy, surgical modality, flap size, postoperative healing, and other clinical outcomes were collected. Techniques, indications, and postoperative complications after repairing with supraclavicular flaps were described. A total of 16 male patients aged 58 to 79 years were involved, including 10 cases of postoperative pharyngeal fistula after hypopharyngeal cancer, 5 cases of postoperative pharyngeal fistula after laryngeal cancer, and 1 case of postoperative pharyngeal fistula after laryngeal and esophageal cancer. In 12 patients, the pharyngeal fistula was repaired by double island folding of the supraclavicular flap; in the remaining 4 patients, the pharyngeal fistula was repaired by the supraclavicular flaps combined with the pectoralis major flaps. The supraclavicular flap was 6 to 8 cm in width and 6 to 15 cm in length. Results: One patient developed partial necrosis at the distal end of the flap, which was successfully treated with debridement and dressing. The flaps grew well in the remaining 15 patients. Among them, a patient with a postoperative pharyngeal fistula after hypopharyngeal carcinoma was implanted with radioactive particles for tumor recurrence at the esophageal entrance, and died in the 11th month after surgery. Conclusions: The supraclavicular flap can achieve excellent results in the repair of pharyngeal fistula.

Bilateral variation in the branching pattern of the subclavian artery: an unusual finding with clinical implications

Abstract The subclavian artery is a significant branch of the aortic arch. We present a rare case of a bilateral variation in the branching pattern of the subclavian artery, observed in an adult male cadaver aged 70 years. On both the sides of the neck, all the branches of the subclavian artery took their origin from its first part. There was a rare occurrence of a cervicodorsoscapular trunk, which gave rise to superficial cervical, suprascapular, and dorsal scapular arteries. The same branching pattern was observed on the left side of the neck, with the presence of another cervicodorsoscapular trunk. Thyrocervical trunk and transverse cervical artery were both absent from the cervical region bilaterally. The inferior thyroid artery was a direct branch from the subclavian artery. Knowledge regarding variations of the subclavian artery is very important as lateral cervical region arteries are important for flap harvesting in plastic and reconstruction surgery. Preoperative radiologic evaluation of pedicles might help in choosing the optimal flap design, prevent ischemic complications, and help to improve overall treatment outcomes.

A Comprehensive Review on the Supraclavicular Flap for Head and Neck Reconstruction

ABSTRACT

The supraclavicular artery flap (SCF) is a highly vascularized fasciocutaneous flap overlying the shoulder. The flap was first described in 1979 by Lamberty but did not gain popularity until much later due to lack of a reliable technique. The main advantages of using the SCF include avoiding microsurgical techniques, requiring only a single-stage operation, shorter operative time compared with alternative options, and a wider patient population including those with comorbidities who may be excluded from more extensive operations including free flaps surgeries. The SCF has been successfully performed on individuals with advanced age, poor nutrition, cachexia, obesity, diabetes, tobacco use, severe chronic obstructive pulmonary disease, hypertension, coronary artery disease, peripheral vascular disease, supraventricular tachycardia, atrial fibrillation, heart failure, asthma, and steroid use. The largest disadvantages of the SCF include the possibility of distal tip necrosis, size limitation without pre-expansion, and a moderately visible donor site scar. The following review and meta-analysis of the SCF details its use historically as both an island and a pedicle flap, and its application in head and neck reconstruction.

A simple option added for reconstruction of posterior neck defects

Background:

Posterior neck defects are uncommon and are mainly caused by infections or tumors. Consequently, the reconstruction options are limited in the literature. They vary according to the size and type of the defect, and options range from grafts to free flaps. In this article, we present a series of cases where we used a transpositional locoregional flap as a simple and effective way for the coverage of posterior neck defects.

Materials and Methods:

In a series of 11 patients, we designed locoregional transpositional flaps unilaterally or bilaterally, according to the defect size. Dissection was carried on a subfascial plane.

Results:

All flaps survived without necrosis. We had two incidents of minimal wound gaping that healed without any intervention.

Conclusion:

In this series, we introduce a new option and its algorithm to reconstruct moderate-sized posterior neck defects using locoregional transpositional flaps, either unilaterally or bilaterally. It is simple, easy to conduct, and has a better color match and less complication rate than other options mentioned in the literature.

A twostep supraclavicular flap method in head and neck reconstruction for refractory osteoradionecrosis

Techniques of reconstructive surgery of the head and neck region have existed since Antiquity, with the pedicled forehead flap of Susruta as a reference. These methods are constantly evolving, with the introduction of free flaps in the 1980s, and more recently new technologies such as CAD-CAM. However, the surgical management of patients treated by radiotherapy for upper airway cancers remains a challenge in terms of functional and aesthetic results. Indeed, cervical irradiation, which alters the quality of skin and vascular tissue, jeopardizes good healing after head and neck reconstructive surgery. In this article, the authors proposed to revisit the standard technique of the pedicled supraclavicular flap. Flap design inspired from the known and described technique of the two-stage forehead flap, for the management of a fragile patient with refractory mandibular osteoradionecrosis.

Potential Benefits from the Use of the Supraclavicular Artery Island Flap for Immediate Soft-Tissue Reconstruction During the COVID-19 Pandemic

Introduction

The coronavirus disease 19 (COVID-19) pandemic has placed significant strains on healthcare resources including staff, theatre, high dependency and intensive care availability. Surgery remains the optimal treatment for the majority of oral malignancies, and primary reconstruction is often necessary to avoid significant morbidity as a result of ablative procedures.

Description

The supraclavicular artery island flap (SCAIF) is increasingly finding a place as an alternative to free flap reconstruction of soft-tissue defects and has several specific advantages when compared to use of a soft-tissue free flap during the COVID-19 pandemic. It can be used for a range of head and neck defects.

Results

We describe our experience with the SCAIF during the pandemic in five patients with a variety of tumour types and locations. All five patients had a successful outcome with none requiring further reconstruction and all had a functional swallow postoperatively, including a patient who underwent a total pharyngeal reconstruction with a SCAIF.

Discussion

The use of a SCAIF during the current COVID-19 pandemic has significant advantages and is a reliable alternative to a soft tissue free flap.

Vascularized Lymph Node Transfer: A Primer for the Radiologist

Lymphedema, the accumulation of lymphatic fluid in the tissues, is a chronic disease and a major cause of long-term morbidity and disability. Lymphedema is usually a secondary condition, often caused by prior oncologic therapy, such as surgery for cancers, radiation therapy, and chemotherapy. Treatment for lymphedema has traditionally been conservative and limited, but new surgical and microsurgical procedures have arisen in recent years. Vascularized lymph node transfer (VLNT) is one of the most promising new microsurgeries. VLNT involves the transfer of functional lymph nodes (LNs) from a healthy donor site to an area of the body with damaged or diseased lymphatic drainage. The goal of the transplant is to restore physiologic LN drainage and improve lymphedema. Donor LNs are commonly found in the groin, axilla, neck, omentum, or submental region. Imaging can be used for preoperative planning to identify donor sites with the richest number of LNs. This can help identify those patients who may be candidates for VLNT and can help identify the best anatomic site for surgical harvest in those candidates. Imaging can be performed with US, CT, or MRI. VLNT preoperative imaging often requires acquisition techniques and reconstruction parameters that differ from those used in routine diagnostic imaging. Furthermore, to properly identify target LNs, the radiologist must be aware of surgical anatomic landmarks. Online supplemental material is available for this article. ^©RSNA, 2020.

Versatility and Reliability of Islanded Pedicled Nasolabial Flap in Head and Neck Cancer Reconstruction

OBJECTIVES

Reconstruction of head and neck cancer ablative defects is challenging. A modification of the nasolabial flap (islanded pedicled nasolabial flap [ipNLF]) is an easy and reliable option for reconstruction of small- to medium-sized defects of the head and neck, especially in resource-constrained and high-volume centers.

STUDY DESIGN AND METHODS

We present the retrospective analysis of 27 consecutive patients reconstructed with ipNLF at two high-volume cancer centers, Homi Bhabha Cancer Hospital, Varanasi, India; and Army Hospital Research and Referral, New Delhi, India. The functional outcomes measured were duration of weaning of feeding and tracheotomy tubes and speech assessment (speech intelligible rating score [SIR]) postsurgery. Complications assessed were flap loss, orocutaneous fistula, donor site wound dehiscence, oral incompetence, and angle of mouth deviation.

RESULTS

The most common ablative defect was of the oral cavity (22 patients), followed by the oropharynx (4 patients) and hypopharynx (1 patient). The mean operating time for flap harvesting and insetting was 57.7 minutes. The mean durations for postoperative feeding tube and tracheotomy removal were 10 and 5 days, respectively. Twenty-four subjects had SIR scores of I or II. None of the subjects had flap loss, orocutaneous fistula, or donor site wound dehiscence. Twenty-five subjects had no oral incompetence, and 26 subjects had no or minimal angle of mouth deviation.

CONCLUSION

This is the largest series of ipNLF to date and emphasizes the versatility, reliability, reproducibility and excellent functional and acceptable cosmetic outcomes of this flap for the reconstruction of judiciously chosen head and neck ablative defects.

Head and neck reconstruction: The supraclavicular flap: technical note

INTRODUCTION

Defects reconstruction after oncologic resection is challenging and complex in head and neck tumors. The aim of this retrospective study is to evaluate the use of the supraclavicular artery island flap (SCAIF) in head and neck reconstruction, in particular, when traditional free flaps is not recommended.

METHODS

We reviewed our two years' experience of the use of SCAIF on a total of 15 cases. In 10 cases, it was used as an alternative to free flaps after head and neck tumors resection. In 5 cases, SCAIF was used for revision surgery after a free flap failure. The indications for flap use have been defects due to resection of stage II-IV cancer in the head and neck region. The operative site, time, complications and functional outcomes were assessed.

RESULTS

We identified 15 patients with a total of 16 SCAIF. One patient had received bilateral SCAIF. Out of the patients, 10 were men and 5 were women. Head and neck oncologic patients underwent tumor resection followed by immediate reconstruction using SCAIF. Among those 15 patients, 10 received previous radiotherapy in the head and neck region. All the patients had undergone multiple surgical procedures. Mean flap dimensions were 6.0cm (range, 5-7cm) wide and 22.0cm (range, 14-26cm) long. The proximal part of the flap was de-epithelialized to match the defect, resulting in a mean skin paddle length of 8.0cm (range, 5-12cm). After an average follow-up duration of 13 months (range 3-20 months), the flap survival rate was 90%. Two patients had had a partial loss of the flap. All the flaps were harvested in less than one hour. The donor sites were closed primarily and did not require any additional surgery. No donor site wound dehiscence had been reported. No infection or cellulitis were observed. None of the patients reported any functional donor site morbidity.

CONCLUSIONS

The supraclavicular flap provides a safe option for head and neck reconstruction of oncologic defects when traditional free flap is not recommended. It is also an excellent alternative to radial forearm free flap (RFFF) in head and neck soft tissue reconstruction, especially in vessel-depleted neck.

Vascularized dermal autograft for the treatment of irreparable rotator cuff tears

BACKGROUND

Irreparable rotator cuff tears (IRCTs) are a challenging problem with diverse treatment modalities. We propose a technique for the treatment of IRCTs in which a vascularized dermal autograft is transferred to the posterosuperior region of the rotator cuff using the supraclavicular artery (SCA) island flap.

MATERIALS AND METHODS

Dissection of 11 fresh cadavers (19 shoulders) was performed, and the SCA island flap was harvested in all specimens. A full-thickness posterosuperior rotator cuff defect was created, and the flap was tunneled under the acromion and secured into position over the defect using multiple suture anchors. Simulated flap perfusion was then assessed, and flap measurements were recorded.

RESULTS

There were 4 male and 7 female cadavers (19 shoulders). Flap perfusion was assessed in 10 shoulders. On average, the flap thickness was 4.7 mm (range, 3.5-7.1 mm); width, 32.6 mm (range, 25.5-38.0 mm); and length, 169.2 mm (range, 132.0-235.0 mm). The average distance from the flap tip to the Neviaser portal was 76.2 mm (range, 48.0-99.6 mm), and that from the flap tip to the anterolateral acromial edge was 54.1 mm (range, 29.5-75.1 mm). The pedicle-to-footprint distance was 113.7 mm (range, 88.5-147.0 mm). The average flap length exceeded the pedicle-to-footprint distance by 55.5 mm (range, 43.5-88.0 mm), indicating adequate excursion of the flap. All flaps demonstrated adequate simulated perfusion after fixation.

CONCLUSION

The SCA island flap may be an option for a vascularized dermal autograft for IRCTs, as shown in this cadaveric study. This illustrates a possible technique with vascular viability.

Sandwich Fascial Anterolateral Thigh Flap in Head and Neck Reconstruction: Evolution or Revolution?

Supplemental Digital Content is available in the text.

Introduction:

The anterolateral thigh perforator flap (ALT) represents the workhorse for most reconstructive efforts in the head and neck regions. The main advantages of this flap are its versatility, the length of the pedicle, and the low morbidity of the donor site. The major drawback is the bulkiness of this flap with the frequent need for secondary revisions. To overcome this, we have developed a novel way to harvest and inset the ALT, called the sandwich fascial ALT flap (SALT).

Methods:

All patients undergoing head and neck reconstruction using the SALT flap from January 2013 to March 2016 were included in this retrospective analysis. The SALT flap was harvested as a composite flap including the superficial fascia, the subscarpal fat, and the deep fascia. At the recipient site, the flap was inset with the deep fascia facing out. A split thickness skin graft (± dermal substitute) was used to cover the deep fascia and the pedicle.

Results:

Eleven patients were included: 8 cases of orbital exenteration, 1 case of forehead reconstruction, and 2 cases of palatal reconstruction after radical maxillectomy. Flap survival was 100%. One patient required an early take back for venous thrombosis. The reconstruction was effective in all cases, allowing a prosthetic rehabilitation when required. Donor-site morbidity was minimal.

Conclusions:

The reconstruction of head and neck defects with a bulky fasciocutaneous ALT flap might not be the best option in every case. The SALT flap could represent a valid alternative for selected cases, with encouraging functional and cosmetic outcomes.
