A Comprehensive Review on the Supraclavicular Flap for 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.

Safe and reliable use of supraclavicular flaps for head and neck reconstruction

The supraclavicular flap is a regional flap in the supraclavicular area nourished by the transverse cervical or supraclavicular arteries. This flap gained popularity in the 2000s as it requires less surgical time than free flap reconstruction and has minimal donor-site morbidity. However, a high rate of postoperative complications has been reported. Moreover, there is ongoing debate regarding the indications and limitations of this flap. In this study, we confined the flap design to the supraclavicular fossa, considering flap vascularity and in an effort to minimize donor site morbidity. Between 2014 and 2023, we performed supraclavicular flap reconstruction in 3 cases of cervical skin defects and 1 case of a pharyngeal mucosal defect. The average defect and flap sizes were 7×3.9 cm and 11.5×4.4 cm, respectively. The lower border of the flap remained above the clavicle, and the lateral border did not exceed the acromioclavicular joint. When the flaps were transferred using the transposition method, the angle of transposition was limited to <90 degrees. When the VY advancement or turnover method was selected, we paid attention to the tension-free flap inset. We successfully reconstructed the defects without flap-related complications, and donor site scars were inconspicuous in all patients. In conclusion, we believe that confining the flap design to the supraclavicular fossa, limiting the indications of this flap to the reconstruction of medium-sized defects, and using tension-free flap insets are important for the successful application of this flap.

Concealed Tracheal Angiosarcoma Beneath a Large Thyroid Mass-An Unexpected Cause of Intractable Hemoptysis

Angiosarcoma is a rare primary tracheal-bronchus origin tumor which was only reported in a few cases. The diagnosis and treatment for such a rare tumor has long been a challenge. In this case, a male hemoptysis patient who was initially misdiagnosed with thyroid carcinoma with tracheal invasion was finally diagnosed with tracheal angiosarcoma. A thick-walled cystic nodular mass was found preoperatively in the right thyroid lobe overlying the tracheal angiosarcoma, which contributed to our initial misdiagnosis. Flap bleeding and necrosis occured after the surgery and patient continued to cough blood even when we excised the whole flap, which suggested the intramural growth and local invasion of the angiosarcoma. This study also reviewed previous literactures on airway angiosarcoma and discussed the treatment strategy.
