Absorbable sutures are used to close lacerations where stitches do not need to be removed later, as they dissolve naturally in the body over time. They are often made from materials such as polyglycolic acid, polylactic acid, or catgut, which are broken down by enzymes or hydrolysis. These sutures are commonly used for deep tissue layers, mucosal surfaces (like inside the mouth), or pediatric wounds where removal would be difficult. Healing usually occurs as the sutures gradually lose strength over 7 to 60 days, depending on the material. Absorbable sutures reduce the need for a follow-up visit for removal and help minimize patient discomfort.
