The fusiform incision is a foundational surgical technique used to excise round, oval, or irregular cutaneous and subcutaneous lesions while converting the resulting defect into a linear wound suitable for primary closure. Designed in a spindle or elliptical shape with tapered apices, the incision aligns with relaxed skin tension lines to minimize closure tension and reduce the risk of contour deformities such as standing cones or "dog ears." This method is frequently employed in dermatologic, plastic, and oncologic surgery to facilitate complete lesion removal, precise margin control, and cosmetically favorable outcomes. Geometric principles such as proper length-to-width ratios, apex angles, and incision orientation are essential to maintaining skin biomechanics, promoting efficient healing, and optimizing scar appearance. The fusiform incision offers functional and aesthetic advantages across various therapeutic and diagnostic procedures by minimizing wound tension and improving tissue apposition. This educational activity enhances clinicians’ procedural competence by providing a detailed understanding of fusiform incision planning and execution. Participants learn to evaluate lesion type, anatomical location, and patient-specific factors to determine appropriate modifications in technique. Instruction focuses on accurate geometric design, tissue handling, layered closure, and complication prevention to ensure optimal results. Emphasis is also placed on interprofessional collaboration with dermatologists, surgical specialists, wound care nurses, and pathologists to promote comprehensive care. Coordinated teamwork improves surgical precision, ensures timely postoperative management, and supports patient-centered outcomes, especially in complex or cosmetically sensitive areas. By integrating evidence-based principles and interdisciplinary communication, clinicians are better equipped to achieve superior clinical and aesthetic results. Objectives: Identify appropriate clinical indications and anatomical locations where a fusiform incision is the preferred technique. Implement best practices in incision design, including the use of appropriate length-to-width ratios and alignment with relaxed skin tension lines. Differentiate between common variations in fusiform incision geometry and their impact on wound closure and scar formation.

The fusiform incision is a fundamental technique in surgical practice, particularly in the excision of cutaneous and subcutaneous lesions. This incision is frequently employed in dermatologic surgery, plastic and reconstructive procedures, and oncologic excisions due to its ability to convert round, oval, or irregular defects into linear closures, resulting in favorable cosmetic and functional outcomes. By removing tissue in a spindle-shaped or elliptical configuration with tapered ends, the fusiform incision facilitates direct primary closure while minimizing the risk of puckering, standing cones, or "dog ears" at the wound margins. This geometric approach is critical for complete lesion excision and promoting healing along lines of minimal tension. Proper planning of the incision concerning relaxed skin tension lines, as well as accurate execution of width-to-length ratios and apex angulation, is essential to achieving optimal wound eversion, tension distribution, and scar aesthetics. This review discusses the principles of fusiform incision design, including key anatomic and biomechanical considerations, common pitfalls, and strategies for preventing contour deformities. Emphasis is placed on integrating sound surgical technique with aesthetic planning to ensure oncologic efficacy and patient satisfaction.

As with other forms of incisional surgery, the main risks include bleeding, hematoma/seroma formation, scar formation (including hypertrophic or keloid scars), and infection. Other risks include damage to underlying structures such as nerves or major vessels, aesthetic disfigurement, and functional impairment. Wound dehiscence and tissue necrosis are less common but can occur, particularly in high-tension closures or in patients with compromised healing. Careful preparation and meticulous surgical technique minimize these risks.

Effective performance of a fusiform incision requires surgical precision and interprofessional collaboration to ensure patient-centered care, optimal outcomes, and procedural safety. Physicians and advanced clinicians must possess strong skills in clinical decision-making, lesion assessment, and geometric planning to design incisions that align with relaxed skin tension lines and anatomical landmarks. Proper tissue handling, incision technique, and layered closure during the procedure are essential to minimize scarring and complications. Nurses play a crucial role in preoperative preparation, intraoperative assistance, and postoperative wound care, encompassing patient education and the early identification of infections or dehiscences. Pharmacists contribute by reviewing medication histories, optimizing perioperative pain control, and preventing adverse reactions, especially in patients with allergies to topical antibiotics or local anesthetics. Interprofessional communication and coordinated workflows are critical throughout the care continuum. Preoperative discussions between clinicians help assess surgical risk and clarify procedural goals. Intraoperatively, real-time coordination between the surgical provider and assisting staff—such as medical assistants or scrub nurses—ensures sterile technique, efficient instrument handling, and accurate specimen labeling. Postoperatively, coordinated discharge instructions and follow-up planning assure continuity of care and reinforce wound management practices. When histologic analysis is needed, collaboration with pathologists supports accurate diagnosis and margin assessment. This team-based approach improves safety, enhances patient satisfaction, and promotes shared accountability across disciplines.

The healthcare team collaborates to ensure patient safety and procedural success. Key interventions include: Preoperative Verifying the correct patient, procedure, and site Reviewing allergies and medications Preparing the sterile field and equipment Intraoperative Assists with tissue retraction and hemostasis, passing instruments, and cutting sutures Ensures the correct handling, labeling, and submission of the surgical specimen Postoperative Applies the final dressing Provides clear verbal and written wound care instructions and schedules the follow-up appointment

Vigilant monitoring by the entire team is crucial for identifying complications early. Key monitoring tasks include: Intra- and postoperative Observe for excessive bleeding, patient discomfort, or vasovagal symptoms. Check the final dressing for any immediate bleed-through before discharge. Postdischarge and follow-up Triage patient calls to screen for early signs of infection (eg, purulent drainage, fever) or hematoma (eg, severe pain, swelling). During follow-up, the team assesses the wound for proper healing and reports any concerns, such as dehiscence or infection, to the physician.
