Debulking of free myocutaneous flaps for head and neck reconstruction using an arthroscopic shaver

Flap Debulking and Secondary Revisions in Head and Neck Reconstruction: A Systematic Review with Clinical Applications

Flap debulking and secondary revisions are an integral factor in providing optimum outcomes to reconstructive patients. This review article summarizes systematically the available literature on flap debulking in head and neck reconstruction. The clinical applications of debulking techniques are discussed, including fractional direct excision, liposuction, and single-stage excision or planning with skin grafting. New technologies are also discussed.

Improving aesthetic outcomes after head and neck reconstruction

PURPOSE OF REVIEW

Tremendous advancements have been made in head and neck reconstruction following oncologic resection. Despite this, many patients are left with disfiguring postoperative changes. The focus of this review highlights various techniques aimed at improving aesthetic outcomes following head and neck cancer therapy, with a focus on liposuction and fat augmentation.

RECENT FINDINGS

Over the past decade, the use of liposuction in treating lymphedema after head and neck cancer therapy has showed promising results. Owing to great improvements in harvesting and purification techniques, fat augmentation has been effectively utilized in correcting a wide array of defects. Although free tissue transfer is frequently used in head and neck reconstruction, there is a scarcity of literature on the indications for flap revision procedures.

SUMMARY

Head and neck reconstructive surgery can lead to significant cosmetic and functional morbidity. Several tools are available to help improve aesthetic outcomes in this patient population. A thorough understanding of the various techniques and their indications is essential for achieving optimal results.Video abstract available: See the Video Supplementary Digital Content 1, http://links.lww.com/COOH/A34.

Secondary contouring of flaps

Perforator flaps are becoming increasingly common, and as primary thinning techniques are being developed, the need for secondary contouring of flaps is decreasing. However, many reconstructive flap procedures still incorporate secondary debulking to improve the functional and aesthetic outcomes. Direct excision, liposuction, tissue shaving with an arthroscopic cartilage shaver, and skin grafting are the four major methods used for secondary debulking. Direct excision is primarily applied in flaps where the skin is redundant, even though the volume is not excessive. However, due to the limited range of excision, performing a staged excision is recommended. Liposuction can reduce the amount of subcutaneous tissue of the flap and protect the vascular pedicles. However, the main drawback of this method is its limited ability to remove fibrotic tissues, for which the use of a shaver may be more convenient. The main drawback of using a shaver is that it is difficult to simultaneously remove excess skin. Skin grafting enables the removal of sufficient excess tissue to recover the contour of the normal limb and to improve the color match, facilitating excellent aesthetic results.

Principles of head and neck reconstruction: an algorithm to guide flap selection

Advances in head and neck reconstruction have resulted in improved outcomes with single-stage repair of defects ranging from intraoral to pharyngoesophageal to skull base defects. Key to success of surgery is choosing an appropriate reconstructive option based on the patient's wishes and fitness for major surgery. Where possible, free tissue transfer provides the best functional and aesthetic outcomes for the vast majority of defects. In this article, we present an algorithm to guide choice of flap selection and review principles of reconstruction and secondary surgery for head and neck defects.
