M is for Maggot Therapy

November 25, 2022

Maggots are sometimes used to help heel wounds.

Maggot therapy, also known as larval therapy or maggot debridement therapy (MDT), involves the controlled application of medical-grade maggots to assist in the healing of certain types of wounds, including diabetic wounds. While it may sound unconventional, maggot therapy has been used for centuries and has gained acceptance as an effective treatment option for specific cases. Here’s an explanation of why maggots are used in diabetic wound care:

  1. Debridement: Diabetic wounds, especially those with poor blood circulation, can develop non-healing or necrotic (dead) tissue. Maggots have a unique ability to selectively feed on dead or necrotic tissue while leaving healthy tissue intact. This process is known as debridement, which helps to clean and remove the non-viable tissue from the wound, promoting the growth of healthy tissue.
  2. Wound cleansing: Maggots secrete enzymes that break down the necrotic tissue, liquefying it and making it easier to remove. Their movement also stimulates the release of wound-cleansing substances, such as antimicrobial agents and growth factors, which can help combat infection and promote healing.
  3. Antibacterial properties: Maggots produce antimicrobial substances that have been shown to be effective against various types of bacteria, including drug-resistant strains. By reducing bacterial burden, maggots can help prevent infection and create a more favorable environment for wound healing.
  4. Stimulation of granulation tissue: Maggots promote the formation of granulation tissue, which is essential for wound healing. Granulation tissue consists of new blood vessels, fibroblasts, and connective tissue that fill in the wound and support the growth of new skin cells.
  5. Increased blood flow: The movement of maggots within the wound can stimulate blood flow to the area. Improved circulation helps deliver oxygen and nutrients to the wound site, which are crucial for the healing process.

It’s important to note that maggot therapy is not a first-line treatment for all diabetic wounds. It is typically considered when other conventional wound care approaches have been unsuccessful. The decision to use maggot therapy is made by healthcare professionals specializing in wound care, and the treatment is performed using medical-grade sterile maggots in controlled settings to ensure safety and effectiveness.
