Surgical suture

Surgical sutures are classified into different types based on their structure, materials, and biodegradability:

Absorbable Sutures: These sutures are naturally absorbed by the body after a period of time and do not need to be removed. They are ideal for tissues that heal quickly. Absorbable sutures are usually made of materials such as polyglycolic acid, polydioxanone, or natural substances like catgut.

Non-Absorbable Sutures: These sutures are not absorbed over time and are used for tissues that require long-term support. Non-absorbable sutures are typically made from nylon, polyester, or silk, and may need to be removed after the wound has healed.

Monofilament vs. Multifilament Sutures: Monofilament sutures are made of a single strand and have a smooth surface, resulting in less friction with tissue. Multifilament sutures, on the other hand, are made of several braided strands, offering greater strength but a higher risk of infection.

Surgical sutures are available in various sizes, typically indicated by numbers and letters. The higher the number, the thinner the suture; for example, sizes 0, 2-0, and 3-0 are thicker and used for stronger tissues, while sizes 6-0 and 7-0 are very thin and are used for delicate surgeries such as eye or plastic surgeries. The choice of suture size depends on the type of surgery, the location of the wound, and the amount of pressure exerted on the tissue.

Surgical sutures, with their various types and sizes, are essential tools in every surgical procedure. They assist surgeons in closing wounds with precision and confidence, helping to expedite the healing process. Sutures are selected based on the type and location of the wound and play a critical role in the success of the surgery and reducing complications afterward.
