title: [Meliorated surgical procedure of Winograd for recurrent onychocryptosis].
abstract: OBJECTIVE
  To explore the improvement of surgical procedure in recurrent onychocryptosis and evaluate its efficacy.
  
  
  METHODS
  The meliorated procedure was designed based on the Winograd surgical protocol. A total of 145 cases of recurrent onychocryptosis were recruited into this retrospective study. The recurrence rate and the difference between recurrent duration and follow-up period were analyzed statistically.
  
  
  RESULTS
  In this series, onychocryptosis was categorized into type I (n = 86), type II (n = 19) and type III (n = 40) respectively. The average follow-up period was 28.72 ± 9.58 months. No recurrent case was found. The outcomes were significant in both statistical analysis and clinical aspects.
  
  
  CONCLUSIONS
  This modified surgical procedure is effective in the treatment of recurrent onychocryptosis.
