When conventional wound closure methods, whether for cosmetic or functional reasons, prove impractical, the need arises for additional tissue reconstruction. This necessitates the use of grafts or flaps. Grafts, like split-thickness skin or mucosal grafts, serve as non-vascularized tissue patches. In contrast, flaps are vascularized, contributing to high success rates in healing. Flaps can originate from distant body sites, requiring microsurgical blood vessel anastomosis near the wound site, earning them the label microvascular "free" flaps. "Regional" flaps involve tissue transfer from non-adjacent areas without such microsurgical connections, while "local" flaps move tissue immediately neighboring the primary defect. Local flaps are further classified into transposition, rotation, advancement, and interpolation, with the latter sometimes categorized as a hallmark of regional flaps by different authors.[1][2][3] Advancement flaps are conceptually the simplest local flaps and, along with rotation flaps, are sometimes known as "sliding" flaps.[4][5][6] For sliding flaps, the tissue is moved or "slid" directly into the adjacent defect without crossing over or under normal tissue, as is seen in transposition and interpolated flaps. Local flap advancement is a versatile cornerstone in cutaneous surgery for several compelling reasons. Firstly, these flaps boast a straightforward conceptual framework, demanding far less spatial reasoning or geometric finesse in their design compared to transposition flaps like z-plasties and bilobed flaps.[7][8] Secondly, they possess the distinct advantage of not leaving secondary defects that necessitate subsequent closure at the flap's initial elevation or harvesting site, a challenge common to transposition, interpolated, regional, and free flaps. Moreover, tissue advancement techniques find utility beyond wound closure scenarios. For instance, V to Y advancement aids in lengthening the columella of the nose in cleft lip cases, restoring the position of the lobule in post-rhytidectomy pixie ear deformities, correcting partial syndactyly, and releasing scar bands that distort anatomical structures such as the eyelid. Furthermore, these techniques extend their utility to cosmetic or gender-affirming procedures like lowering the hairline with scalp advancement and forming the basis of facelift surgery through cheek advancement.

The most common complication of local flap reconstructive surgery is either partial or total flap necrosis, leading to wound dehiscence (see Image. Local Flap Complication).[22] Flap loss may result from several causes, but vascular compromise is the most common. Venous congestion is more common than arterial inflow obstruction. Still, both may result from a flap design with insufficient width relative to its length, stretching the flap excessively, which narrows the lumina of small caliber vessels, or excessive flap thinning, which disrupts the subdermal vascular plexus. Vascular compromise may also be caused by extrinsic factors, such as pressure, resulting from compression due to a hematoma or edema due to inflammation or infection. Changes in the color and turgor of the flap will be the first indication of vascular compromise: a dusky, ecchymotic flap that is swollen and firm is likely to suffer from venous insufficiency. In contrast, arterial insufficiency will result in a pale and cool flap. Venous insufficiency, while far more common than arterial insufficiency, will ultimately result in enough congestion to obstruct arterial inflow. If identified early, vascular compromise may be alleviated by releasing some closing sutures, thereby decreasing tension on the flap. If a hematoma has formed under the flap, draining it will promote improved circulation. Infections should be treated with drainage, irrigation, and antibiotics to reduce inflammation. If none of these options are appropriate, applying nitroglycerin paste may improve flap perfusion. Medicinal leeches may also be helpful, as they remove congested blood directly and promote circulation by administering a natural anticoagulant, hirudin. However, antibiotic prophylaxis with a fluoroquinolone should be provided when leeches are employed due to the risk of infection with Aeromonas hydrophila.

After flap necrosis, infection is the most common complication of local flap transfer.[22] In many instances, infection occurs at the site of flap necrosis, either as a cause or a result of the necrosis. Bleeding with potential hematoma formation is the next most common complication. Even in patients taking multiple blood thinners, though, hematomas with appropriate intraoperative hemostasis are rare. Excessive use of electrocautery can, however, contribute to flap necrosis. Lastly, displacement of free margins, such as the eyelid, lip, eyebrow, and nasal ala, are predictable results from flap designs that place tension on these freely mobile structures. To avoid traction on a free margin, the primary tension vector for closure should be parallel to the free margin rather than perpendicular.[23][24] Corticosteroid injections may be employed if scarring causes an untoward cosmetic outcome, particularly within the first few postoperative weeks. If injections do not produce the desired effect, skin resurfacing with dermabrasion or laser treatments may be required. If those options fail, revision surgery may be considered.

Advancement flaps require a multidisciplinary healthcare team with specific roles and responsibilities to ensure optimal patient-centered care. Physicians, including plastic surgeons and dermatologists, need the skills to assess wound characteristics, choose the most suitable flap type, and perform precise surgical techniques. They must also possess a strong ethical foundation, ensuring informed consent and considering patients' preferences. Nurses are critical in preoperative and postoperative care, monitoring patients for complications, wound healing, and infection prevention. Nurses and surgeons must educate patients in proper aftercare as advancement flaps must be monitored until complete healing occurs.[25][26] Pharmacists contribute by providing medications and ensuring proper pain management, prophylactic antibiotics, and any necessary wound care supplies. Surgeons must collaborate with nurses, pharmacists, and other healthcare professionals to ensure a smooth surgical process. They must convey the patient's history, surgical plan, and specific care requirements. Nurses and pharmacists, in turn, should communicate any concerns or changes in the patient's condition to the surgeon promptly. This coordinated approach enhances patient safety, prevents complications, and improves outcomes. Furthermore, a shared sense of responsibility among the healthcare team members is paramount. Each professional must understand their role in the patient's care and adhere to best practices. Ethical considerations, such as respecting patient autonomy and ensuring informed consent, are non-negotiable. Beyond individual responsibilities, the team should collectively strategize and plan each stage of the surgical procedure and postoperative care, considering patient preferences and safety measures. Team performance is further enhanced through regular training and skill development, staying updated with advancements in flap techniques, and embracing a culture of continuous learning. In summary, for advancement flap procedures, effective teamwork, ethical conduct, skillful execution, and clear communication among healthcare professionals are essential components in delivering patient-centered care that improves outcomes, enhances safety, and optimizes team performance.
