cryotherapy explained

How Cryotherapy Works

     1.  Mechanism of Action:

​

• Cryogens: Substances like liquid nitrogen, argon gas, or carbon dioxide are used to create extremely low temperatures.

​

• Cellular Damage: The rapid freezing and thawing of tissues cause ice crystals to form inside cells, leading to cellular damage and death. This is particularly effective for destroying abnormal or diseased tissues.

​

• Vascular Stasis: Freezing also causes blood vessels to constrict, reducing blood flow to the treated area, which can help minimize bleeding and swelling.

​​

​

     2.  Delivery Methods:

​

• ​Topical Application: Directly applying a cryogen to the skin using a cotton swab or spray.

​​

​

     3.  Cryoprobe:

​

• A device inserted into or applied to the tissue to deliver controlled freezing.

​

Medical Applications of Cryotherapy

​

     1.  Dermatology

​

• Wart Removal: Effectively removes common and plantar warts.

​

• Actinic Keratosis: Treats precancerous skin lesions.

​

• Skin Tags and Moles: Removes benign skin growths.

​​

​

     2.  Oncology

​

• Prostate Cancer: Cryoablation can be used to freeze and destroy cancerous prostate tissue.​

​

• Liver Cancer: Treats certain types of liver tumors.

​

• Breast Cancer: Sometimes used for small, localized breast tumors.

​

     3.  Pain Management and Rehabilitation

​

• Cryotherapy Chambers: ​Whole-body cryotherapy involves short exposure to extremely cold air, which can reduce inflammation, pain, and muscle soreness.

​

• Localized Cryotherapy: Targeted treatment for injuries such as sprains, strains, and postoperative pain.

     4.  Rheumatology

• Rheumatoid Arthritis: Reduces joint inflammation and pain.

​

• Psoriatic Arthritis: Helps manage symptoms by reducing inflammation.

Veterinary Applications of Cryotherapy

     1.  Dermatology

​

• Warts and Skin Tumors: Similar to human applications, cryotherapy can remove warts and benign skin tumors in animals.

​

• Equine Sarcoids: Treats common skin tumors in horses.

     2.  Oncology

​

• Oral Tumors in Pets: Cryotherapy can be used to treat certain types of oral tumors in dogs and cats.

​

• Mammary Tumors: Sometimes used for small, localized mammary tumors in pets.

     3.  Pain Management

• Postoperative Pain: Reduces pain and inflammation following surgical procedures in animals.

​

• Musculoskeletal Injuries: Helps manage acute injuries in pets and horses.

Benefits of Cryotherapy

• Minimally Invasive:  Often performed as an outpatient procedure with minimal recovery time.

​

• Targeted Treatment: Precisely targets abnormal or diseased tissues, sparing surrounding healthy tissues.

​

• Reduced Bleeding and Swelling: The vasoconstrictive effects help minimize bleeding and swelling during and after treatment.

​

• Versatility: Effective for a wide range of conditions in both human and veterinary medicine.

Considerations and Contraindications

• Patient Suitability: Not all patients are suitable candidates for cryotherapy. Contraindications include certain cold intolerance conditions, severe cardiovascular or respiratory diseases, and cryoglobulinemia.

​

• Side Effects: Common side effects include temporary pain, redness, swelling, and blistering at the treatment site.

​

• Professional Guidance: Should be performed by a trained healthcare or veterinary provider to ensure safety and effectiveness.

Cryotherapy is a versatile and effective treatment option for various medical and veterinary conditions, leveraging the therapeutic effects of extreme cold to promote healing and manage disease.
