Introduction
Corn can be treated with corn plaster. The specific method involves soaking the foot in warm water first to soften the local keratinized layer, then carefully trimming off the hyperkeratotic surface of the corn. After that, place the red medicated portion in the center of the corn plaster directly over the core of the corn and secure it firmly, changing the plaster regularly. Alternatively, physical treatments such as liquid nitrogen cryotherapy, carbon dioxide laser, or electrocautery can also be used for removal.
Generally, corns are localized, conical hyperkeratosis of the skin on the feet caused by prolonged pressure and friction. Treatment options include medication, physical therapy, or surgery as advised by a physician. Specific approaches are as follows:
1. Medication
Topical medications can be used for treatment, with corn plasters being the most common. The procedure typically involves soaking the foot in warm water to soften the local keratinized layer, then carefully trimming away the surface thickened portion of the corn. Next, the red medicated core of the corn plaster is precisely positioned over the center of the corn and securely applied. The dressing should be changed regularly, gradually corroding the keratin plug so that the corn eventually falls off.
2. Physical Therapy
If medication proves ineffective, physical treatments may be performed under medical supervision, such as liquid nitrogen cryotherapy, carbon dioxide laser ablation, or electrocautery to remove the corn.
3. Surgical Treatment
For patients who do not respond to conventional treatments, surgical removal of the corn may be performed. Surgery allows rapid elimination of the corn and achieves therapeutic results.
After removing the corn's keratin plug, preventive measures are essential. Avoid wearing shoes that are too hard or tight, prevent local pressure, and correct any foot deformities to reduce the likelihood of recurrence.
