What blade size is used for excision, trimming, and dissecting tissue?

• A. #10
• B. #3
• C. #11
• D. #15

Answer: (D)

For precise excision, trimming, and tissue dissection, you want a blade designed for fine control. The small curved blade provides a narrow, sharp edge that follows contours and margins smoothly, letting you remove a lesion cleanly, trim excess tissue, and dissect delicate layers with minimal collateral damage. Its compact size and curved tip give you tactile feedback and better visibility in tight spaces, which is essential for precise work around delicate structures.

Other blades are suited to different tasks: a larger general-purpose blade makes quicker, broader skin incisions but is less precise for small margins; a stab-type blade excels at quick entry incisions but isn’t ideal for controlled dissection or trimming; and blades with mid-sized or straight geometry lack the finesse needed for delicate tissue work.
