Successful Treatment of Plantar Hyperkeratosis in the Form of Recurrent Corns With Split-Thickness Sole Skin Graft

Ann Plast Surg. 2018 Feb;80(2S Suppl 1):S55-S58. doi: 10.1097/SAP.0000000000001304.


Introduction: Plantar hyperkeratosis, such as corns and calluses, is common in older people and associated with pain, mobility impairment, and functional limitations. It usually develops on the palms, knees, or soles of feet, especially under the heels or balls. There are several treatment methods for plantar hyperkeratosis, such as salicylic acid plaster and scalpel debridement, and conservative modalities, such as using a shoe insert and properly fitting shoes.

Methods: We present an effective method of reconstructing the wound after corn excision using a split-thickness sole skin graft (STSSG). We harvested the skin graft from the arch of the sole using the dermatome with a skin thickness of 14/1000th inches.

Results: Because the split-thickness skin graft, harvested from the sole arch near the distal sole, is much thicker than the split-thickness skin graft from the thigh, it is more resistant to weight and friction. The healed wound with STSSG coverage over the distal sole was intact, and the donor site over the sole arch had healed without complication during the outpatient follow-up, 3 months after surgery.

Conclusions: The recovery time of STSSG for corn excision is shorter than that with traditional treatment. Therefore, STSSG can be a reliable alternative treatment for recurrent palmoplantar hyperkeratosis.
