title: Partial matricectomy with a CO2 laser for ingrown toenail after nail matrix staining.
abstract: BACKGROUND
  Ingrown toenail is a common nail disease that causes pain, discomfort, and difficulty in walking. It is treated with either conservative therapy or surgery.
  
  
  OBJECTIVE
  To present a new surgical approach to ingrown toenail.
  
  
  METHODS
  For 19 ingrown toenail borders of 14 toes in 14 patients (1 male and 13 females), the nail matrix was stained with methylene blue and then partial matricectomy was performed with a CO2 laser.
  
  
  RESULTS
  There was no recurrence at 18 nail borders after a mean follow-up period of 13.4 months, whereas a spike grew at one border but caused no walking pain. No serious complications occurred. Cosmetic improvement was also satisfactory.
  
  
  CONCLUSIONS
  Partial nail matricectomy with a CO2 laser after staining the nail matrix with methylene blue allows visual confirmation of the completeness of cauterization.
