What types of suture material are there?

Suture material comes in many different forms. Some threads are broken down by the body over time. These are called absorbable materials. They dissolve on their own and do not need to be removed. They are often used for internal stitches, for example on organs or beneath the skin. There are also non-absorbable threads, which either stay in the tissue permanently or need to be removed by a doctor after a set amount of time. These threads are usually used for skin stitches or in areas where a particularly strong hold is needed.

The material itself can also vary. Some threads are made from natural substances such as silk or gut, while others are made from modern synthetic materials such as polyamide or polypropylene. The choice depends on the type of wound, the part of the body affected, and the requirements for strength and tolerability.

How does stitching a wound work?

When closing a wound, the tissue is sewn together using a needle and the chosen suture material. There are different techniques, and the right one is chosen depending on the size, shape, and position of the wound. For small, clean cuts, a simple continuous stitch is often enough. For larger or more complex wounds, several layers may be stitched one after another to connect the inner and outer areas securely.

After stitching, the suture material either stays in the body if it dissolves on its own, or it is removed after a few days to weeks. How long the stitches need to stay in depends on the location and how quickly the wound heals. On the face, for example, skin stitches are usually removed after five to seven days. On other parts of the body, it may take longer.

What should you be aware of after stitches?

After a wound has been stitched, it is important to keep the area clean and dry to avoid infection. Depending on the advice given, the wound should be checked regularly and dressed if needed. With absorbable material, there is no need to have the stitches removed, as the threads break down on their own. Non-absorbable stitches are removed by agreement once the wound has healed securely.

Sometimes there may be redness, swelling, or mild pain around the stitched area. This is usually nothing to worry about in the first few days after the procedure. However, if the wound becomes very red, throbs, produces pus, or if a fever develops, it is advisable to see a doctor.

Why is a particular suture material chosen?

The decision to use a certain suture material depends on many factors. In sensitive areas such as the face, very fine threads are usually used to keep scarring to a minimum. In the abdomen or on internal organs, dissolvable materials are preferred so that a second procedure to remove the stitches is not needed. For parts of the body under a lot of strain, or for people with certain existing health conditions, a particularly strong, non-absorbable material may be the better choice.

Allergies or intolerances can also play a role. In very rare cases, the body may react to certain threads. In that situation, a different material is used instead.

Other methods for closing wounds

As well as traditional threads, there are other ways to close wounds. Metal staples are often used for larger surgical cuts because they hold quickly and securely. For smaller, clean wounds in areas that are not under much strain, special adhesive strips or medical glue may sometimes be used. These methods are particularly gentle and often leave very little visible scarring.

Suture material is an important tool in helping wounds heal safely and in preventing complications. The choice and use of suture material is always individual, adapted to the specific situation and how healing is progressing.
