Mechanical debridement involves carefully shaving or trimming away the thickened skin and hard central core of a corn using sterile instruments, typically performed by a podiatrist or trained clinician. This offers immediate relief of pressure and pain, especially when the corn is deep or causing discomfort with walking. Debridement does not remove the underlying friction or pressure that caused the corn, so recurrence is common without footwear modifications or offloading. It is a useful option for patients who cannot safely use chemical treatments like salicylic acid, including those with diabetes, neuropathy, or poor circulation. Regular follow-up and proper shoe fit are key to preventing the corn from growing back.
