AB AT-A-GLANCENail  surgery  requires  careful  patient  selection  to  prevent  unnecessary  complications.The  technique  used  for  anesthesia  depends  on  the  type  of  surgery.  Distal  digital  block  with  ropivacaine  2  mg/mL  is  usually  the  best  option.Partial  nail  avulsion  allows  the  exploration  and/or  the  treatment  of  a  subungual  lesion  or  the  removal  of  a  pathologic  nail  plate.  Total  nail  plate  avulsion  should  be  discouraged  to  prevent  nail  bed  shrinking  and  distal  embedding.Nail  biopsies  are  performed  to  determine  the  histopathologic  features  of  a  lesion  or  to  clarify  an  uncertain  clinical  diagnosis.Lateral  longitudinal  biopsy  is  the  best  technique  for  inflammatory  disorders  or  lateral  longitudinal  melanonychia.Punch  biopsy  less  than  3  mm  in  the  distal  matrix  does  not  produce  serious  dystrophy.Tangential  shave  excision  is  the  best  option  for  superficial  matrix  tumors  such  as  wide  longitudinal  melanonychia  or  superficial  epithelial  benign  tumors.
