What is the typical maximum depth of penetration achievable with cryotherapy?

• A. 2 to 3 cm.
• B. 4 to 5 cm.
• C. 6 to 8 cm.
• D. 10 cm.

Answer: (B)

Cryotherapy mainly cools tissue through conduction, with the deepest reliable cooling reaching only a few centimeters beneath the surface. In typical clinical practice, the greatest depth you can expect to affect with standard cold modalities is about 4 to 5 cm. This depth is enough to influence superficial to mid-level tissues, like nearby muscle layers, without risking injury to deeper structures. Shorter or shallower cooling, such as 2–3 cm, is possible but does not represent the usual maximum depth achieved. Going deeper than roughly 5 cm would require more aggressive or specialized methods and increases the risk of tissue damage, which is why 4 to 5 cm is the commonly cited maximum.
