Reconstruction of cervical scar contracture using axial thoracic flap based on the thoracic branch of the supraclavicular artery

Cervico-acromial flap for large defects in face and neck reconstruction: 34-year experience

BACKGROUND

Extensive cervicofacial defects often lead to functional and aesthetic impairments. The pre-expanded cervico-acromial flap technique is reliable and cost-effective for addressing such defects.

OBJECTIVE

To introduce our 34 years' experience on pre-expanded cervico-acromial flap technique, emphasizing key surgical techniques.

METHOD

The supraclavicular artery and its main branches were evaluated with Doppler ultrasound preoperatively. Pre-expansion was performed in most cases to optimize flap dimensions, with the tissue expander placed at the subfascial level to preserve adequate blood supply. Once fully expanded, the cervico-acromial flap was raised and rotated to cover the cervicofacial defects. The pedicle was divided three weeks postoperatively.

RESULTS

A total of 19 patients (5-57 years) were finally included in this retrospective study. They all accepted the above-mentioned technique by the same senior surgeon from October 1990 to October 2024. The expanded flap sizes ranged from 15 × 7 cm to 35 × 15 cm. The follow-up lasted from 6 months to 9 years. All flaps survived without necrosis or infection. Patients expressed high satisfaction with functional and cosmetic outcomes in both donor and recipient areas.

CONCLUSIONS

The pre-expanded cervico-acromial flap is safe and effective for repairing the extensive cervicofacial defects. Thorough understanding of this flap's blood supply and careful design based on the vascular anatomy help to improve the flap's survival rate.

Subclavicular flap: A valid reconstructive option among anterior chest flaps in oral cancer patients

BACKGROUND

The subclavicular pedicled flap is based on the thoracic branch of the supraclavicular artery, and it represents a versatile reconstructive option for low-middle third face defects. Since its use in head and neck surgical oncology has not been popularized yet, we propose its application for oral cavity reconstruction after cancer resection by showing favorable results.

METHODS

Eighteen subclavicular pedicled flaps were used to treat intraoral defects after oral squamous-cell cancer resection between June 2015 and December 2018. Tumor dissection type, complications, donor and reconstructed area results, and functional and aesthetic outcomes were assessed.

RESULTS

No major complications were observed and all of the flaps survived. Adjuvant therapy was administered without delay when needed, and all of the patients had normal functional outcomes and good aesthetic results.

CONCLUSIONS

The subclavicular flap is an excellent choice for the reconstruction of oral cavity defects. Selection of patients should exclude positive lower-third neck node and include appropriate informed consent for women due to the possibility of deformity of the breast. In our opinion, this flap has the potential for common application given its consistent anatomy and donor site advantages, including long pedicle, high pivot point, and relatively unlimited flap width.

Supraclavicular flap practice patterns and outcomes: A survey of 221 AHNS surgeons

OBJECTIVES

To describe American Head and Neck Society (AHNS) surgeon supraclavicular flap (SCF) practice patterns and to identify variables associated with SCF complications.

METHODS

The design is a cross-sectional study. An online survey was distributed to 782 AHNS surgeons between November 11, 2016, and December 31, 2016. The primary outcome was frequency of SCF complications. Independent variables included demographics, training, practice patterns, and SCF techniques.

RESULTS

Adequate survey responses were obtained from 221 AHNS surgeons. Among these, 54.3% (n = 120) performed supraclavicular flaps (SCFs). Most surgeons used the SCF for cutaneous (n = 85; 78.7%) or parotid-temporal bone (n = 59; 54.6%) defects. Nearly one-third (n = 31; 29.8%) of surgeons experienced more than a "few" SCF complications. Surgeons experienced fewer pectoralis major flap (P < 0.001) and radial forearm free flap (P < 0.001) complications compared to SCF complications. Univariate analysis demonstrated no association between surgeons with "few" SCF complications and Doppler use in SCF design (P = 0.90), harvest location (P = 0.51), and pedicle skeletonization (P = 0.25). Multivariable logistic regression revealed that surgeons performing more than 30 SCFs compared to less than or equal to 30 SCFs had a greater odds of having "few" SCF complications (odds ratio 7.1, 95% confidence interval [1.1-43.9], P = 0.04).

CONCLUSION

A majority of surgeons performing SCFs use the flap to reconstruct cutaneous and parotid-temporal bone defects. The significance of relatively higher SCF complications compared to other routine flaps should be explored further. Surgeon experience with the SCF appears to be significantly associated with SCF success, whereas training characteristics, practice patterns, and technical variations may not be associated with SCF outcomes.

The neck burn scar contracture: a concept of effective treatment

A neck scar contracture can severely and negatively affect the function of mastication, phonic, or breathing and result in neck pain and issues with esthetics. The best way is of course to avoid such contracture by means of non-surgical treatment such as use of a growth factor. The basic fibroblastic growth factor is clinically well proven in decreasing scar formation and improving healing. There are numerous reconstructive methods for neck contracture, especially when the lesions are relatively limited in part of the neck. However, a very severe and full circumferential scar contracture requires extensive reconstruction. The thin groin flap is one of the answers and well matches with the tissue texture and maintains the flexibility. Even with extensive burns and delayed reconstructions due to resuscitation first, the groin area is well preserved and can be safely harvested by dual vasculature systems of the superficial circumflex iliac artery and superficial epigastric artery, which warrant more reliability compared to the perforator flaps in this area. More demanding and stringent forms of the neck burn scar contracture are the sequelae of radiation. A radiation burn or radiation injury can be progressing and hard to heal. Adipose-derived stem cells can reverse the scar contracture as the surrounding tissue is softened and can accelerate wound healing. In this review, different types of neck burn scar contracture and reconstructive methods are summarized, including innovative use of bFGF and ADSCs in the management of difficult wound healing and scar contracture.

The pre-expanded subclavicular island flap: A new tool for facial reconstruction

BACKGROUND

The anterior chest is an excellent donor site for cervicofacial reconstruction. Studies of chest flaps began as early as 1988 at our institution. We identified a new branch of the supraclavicular artery that nourishes the anterior chest, and on the basis of this finding, we created a new flap called the subclavicular flap. Unlike the supraclavicular flap, which is pedicled by the deltoid branch, this flap is primarily pedicled by the thoracic branch, and it shares similar vascular territory with the deltopectoral flap. In China, this flap has been widely used for neck reconstruction since our first publications on it in 1993. However, reports of its application are limited. To popularize the use of this flap, we present our experiences with pre-expanded subclavicular island flaps for the repair of facial scars.

METHODS

Fifteen patients with facial scars underwent reconstruction with these flaps. All flaps underwent pre-expansion before being transferred to the face through a subcutaneous tunnel. The pivot point was in the supraclavicular region and allowed the flap to reach the mid-face without compulsive positioning. Donor sites were closed primarily.

RESULTS

Flaps sizes ranged from 4 cm × 5 cm-10 cm × 17 cm. Fourteen flaps survived completely with satisfactory colour and texture. Total flap loss occurred in one patient, who was then treated by harvesting a skin graft from the dying flap. One patient experienced venous congestion, and the flap was successfully salvaged by pure vein anastomosis.

CONCLUSION

Pre-expanded subclavicular island flaps have similar benefits to supraclavicular and deltopectoral flaps, and they may emerge as one of the best choices for cervicofacial reconstruction globally.
