Nylon Sutures

Purpose & Use

• Nylon sutures are synthetic, non-absorbable sutures used for closing skin, soft tissue, or surgical wounds.

• Common in general surgery, plastic surgery, and minor procedures.

• Often chosen for their high tensile strength and minimal tissue reaction.

Material & Properties

• Made of nylon (polyamide), which is strong, smooth, and flexible.

• Monofilament or braided forms:

  • Monofilament: single strand, less tissue drag, lower infection risk.

  • Braided: multiple fibers twisted together, stronger knot security but slightly higher infection risk.

• Non-absorbable — stays in tissue until removed.

Sizes & Classification

• Nylon sutures come in various sizes, typically ranging from 6-0 (very fine, used in delicate tissue like the face) to 5 or 4 (thicker, used in heavy tissue like fascia).

• Size selection depends on tissue type, wound location, and desired cosmetic outcome.

Needles

• Supplied pre-attached to surgical needles.

• Needle types:

  • Curved needles (most common for internal tissues).

  • Straight needles (used in skin or minor procedures).

• Needle shapes vary: reverse cutting, taper point, or cutting, depending on tissue type.

Packaging & Sterility

• Usually individually sterile-packed, ready for use.

• Available in single units or boxes containing multiple sutures of the same or mixed sizes.

Safety & Handling

• Handle with sterile technique to avoid contamination or infection.

• Non-absorbable — must be removed after wound healing (typically 5–14 days for skin, depending on location).
