What are permanent stitches?
Permanent stitches, also known as non-absorbable sutures, are used in surgical procedures to close wounds or incisions. Unlike absorbable stitches, which dissolve on their own over time within the body, permanent stitches do not degrade and must typically be removed by a healthcare professional after the wound has sufficiently healed.
Permanent sutures are made from materials that are not broken down by the body's enzymes or hydrolysis. These materials may include:
- Silk: Although natural, it is treated to be non-absorbable for surgical use.
- Nylon (polyamide): Synthetic nylon sutures are commonly used for skin closures.
- Polyester: Synthetic polyester sutures can also be used for various tissue repairs.
- Polypropylene: Known for its high tensile strength, it is often used in cardiovascular and neurological surgeries.
- Stainless steel: Used in orthopedic surgery and for sternum closure after cardiac surgery due to its high tensile strength and minimal tissue reaction.
The choice of using permanent stitches depends on the type of surgery, the rate of healing, the necessity for long-term tissue support, and the likelihood of infection, among other factors. The usage of these non-absorbable sutures is often critical in tissues that take an extended period to heal or where added strength and support are required for longer durations.
It's important to follow your healthcare provider's advice for the care and eventual removal of permanent stitches to minimize scarring and ensure proper healing.
