Extranasal Transposition Flaps
Description
In this presentation on extranasal transposition flaps, June Zhang discusses the versatile application, design, and execution of these surgical flaps, emphasizing their utility in altering tension vectors and accessing tissue reservoirs. Transposition flaps are highlighted for their adaptability in various scenarios, such as closing horizontally oriented defects or minimizing incision lines in dynamic areas. Key concepts include proper flap design based on the primary tension vector determined by the last lobe's closure and the significance of favorable tissue reservoirs for optimizing flap movement. The theory is illustrated using the Limburg rhombic flap, highlighting design principles and execution strategies, including incision and lifting techniques to preserve blood supply while avoiding nerve damage. The presentation also covers various surgical cases demonstrating the effective use of simple and multi-lobe transposition flaps, emphasizing the importance of selecting appropriate vectors, ensuring minimal distortion of free margins, and accounting for secondary motion. Finally, the role of tacking sutures in securing the flaps is underlined, along with the nuances in flap sizing and design adjustments tailored to the specific anatomy of the region involved.

- Transposition flaps are highly versatile and applicable in various surgical scenarios.
- These flaps are particularly effective for altering tension vectors, protecting free margins, and filling defects using adjacent tissue reservoirs.
- Designing transposition flaps should prioritize understanding tension vectors and optimal placement within tissue reservoirs.
- Key design concepts include ensuring the last lobe of the flap is placed in favorable tissue for optimized movement and minimal distortion of free margins.
- Secondary motion must be accounted for when closing defects, as it influences flap movement and closure efficacy.
- Using tacking sutures effectively can reduce tension on primary defects and aid flap positioning.
- Flap design and execution, including techniques for incising and lifting, are crucial for successful outcomes, emphasizing the need for blood supply preservation and motor nerve protection.
- The choice of flap size, take-off point, and angle is critical, as they determine how well a flap will adapt to its new location and meet functional and aesthetic needs.
