Comparison of Phenol and Trichloroacetic Acid Chemical Matricectomies in the Treatment of Unguıs Inkarinatus

Unguis inkarinatus are a common condition that cause inconvenience,pain and limit daily functioning.Unguis inkarinatus are most frequently seen in adolescents and young adults [1,2].Unguis inkarinatus are reviewed in 3 stages.Stage 1 unguis inkarinatus are characterized by erythema, slight edema, and pain with pressure to the lateral nail fold.Stage 2 is marked by increased symptoms of stage 1 as well as drainage and infection.Stage 3 unguis inkarinatus display magnified symptoms of stage 1 accompanied by lateral wall thickening and granulation tissue [1,2].Partial nail plate avulsion and chemical matricectomy is the most successful method for the treatment of ingrown toenails [1,4].Phenol, sodium hydroxide and TCA were used for chemical matricectomy [1,2].Chemical matricectomy with phenol has a low recurrence rate and good cosmetic results, but it produces extensive tissue destruction and can result in drainage and a delayed healing time [1,2,4,5].These side effects have brought forward the use of chemical agents including sodium hydroxide and TCA for chemical matricectomy [1,2,4,5].It has been reported in that phenol and TCA chemical matricectomies have success rates of about 95% [2-5].There are no studies in the literature, comparing the efficacy and postoperative morbidity rates of both chemical matricectomy methods.The aim of our study was to compare the efficacy and postoperative morbidity of phenol and Trichloroacetic Acid (TCA).
