- The length of time the sutures remain. The longer the sutures are in, the more reactivity occurs.
- The size of the sutures used. The larger the caliber of the suture, the more reactivity. The increase of one suture size results in a 2- to 3-fold increase in tissue reactivity.
- The type of suture material used. Synthetic or wire sutures are much less reactive than natural sutures (eg, silk, cotton, catgut). Monofilament suture is less reactive than a braided suture.
- The region of the body the suture is used affects tissue reactivity. The chest, back, extremities, and sebaceous areas of the face are more reactive.
