Background: Plantar keratoma are common hyperkeratinized, deep-seated lesions, often located on weightbearing areas of the foot. Such lesions are frequently associated with pain and disability. Intractable plantar keratomata (IPK) are highly recurrent and, in most patients, require regular, palliative treatment visits with a significant impact on patient time, cost, and quality of life.
Methods: We undertook a retrospective chart review of 9 patients (with a total of 21 lesions) who underwent a minimum of two treatments using microwave therapy to their IPK. Pain levels were assessed at each of their treatments using a 10-point scale and patients were invited for review for follow-up in the following year. A total of seven patients undertook four treatments and were included in the final analysis.
Results: Mean baseline pain scores significantly dropped with each subsequent treatment, equating to a 90.4% mean reduction in pain between the first and fourth visits, with 71.4% of patients reporting a zero-pain rating at their final treatment visit.
Conclusions: The use of microwave therapy has been shown to be effective in producing significant and prolonged pain reduction in a cohort of patients with painful IPK.
