Poly-p-dioxanone, commonly abbreviated as PDO, PDS or PPDO, is a synthetic biodegradable polymer. It is used in various medical applications, particularly in the field of surgery and sutures. PDO sutures are known for their strength and flexibility, making them ideal for use in surgeries that require long-term support for tissues or organs.

Here are some key points about PDO:

  • Biodegradable: PDO is designed to break down in the body over time. This property reduces the need for suture removal in many cases, as the material naturally degrades.
  • Tensile Strength: PDO sutures are known for their high tensile strength, which means they can hold tissues together securely during the healing process.
  • Flexibility: PDO is a flexible material, which is beneficial when suturing tissues that need to move or stretch as part of their normal function.
  • Absorption Rate: The rate at which PDO is absorbed by the body depends on factors like the thickness of the material and the location of the sutures. Typically, PDO sutures can provide support for several weeks to months before they are absorbed.
  • Biocompatible: PDO is generally well-tolerated by the body and does not cause significant inflammation or adverse reactions.
  • Applications: PDO sutures are commonly used in plastic surgery, ophthalmic surgery, and various other surgical procedures where long-lasting support is required.


Polydioxanone (PDO) is considered to be safe for medical use. It is a biocompatible and biodegradable material commonly used in surgical sutures due to its excellent tensile strength and low risk of tissue damage.

Polydioxanone suture is commonly used for surgical procedures as it is a biodegradable material that is absorbed by the body over time. It is typically utilized for closing surgical incisions or wounds

The lifespan of PDS suture can vary depending on various factors such as the location of the suture, the individual patient’s healing process, and the specific type and size of the suture used.

Generally, PDS (Polydioxanone) sutures are absorbable and are designed to dissolve within a certain timeframe, typically ranging from several weeks to a few months.

The cost of a PDO thread lift can vary depending on various factors such as the location, the experience and expertise of the practitioner, and the number of threads needed. On average, a PDO thread lift can range from $1,500 to $4,500.

Polydioxanone is a synthetic material. It is a biodegradable polymer that is made through the polymerization of dioxanone monomers.

Yes, there are risks associated with PDO (Polydioxanone) threads. Some of the potential risks include infection, bruising, swelling, pain, asymmetry, and the thread becoming visible or palpable under the skin. 

Polydioxanone is absorbable, meaning that it can be broken down and absorbed by the body over time.
