title: Congenital aural sinuses: clinical study and application of microsurgery.
abstract: METHODS
  The authors studied 45 cases of congenital aural sinuses.
  
  
  RESULTS
  Aural sinuses were observed on both sides in 17 cases (37.8%) and in girls (24 cases, 53.3%). Family history was positive in 12 cases (26.6%), and history of local infection was present in 40 cases (88.9%). The opening of aural sinuses was located most frequently in the marginal helicine region (36 cases, 80%).
  
  
  CONCLUSIONS
  Microsurgery was extremely effective for accurate determination of the margins of intricately ramified aural sinuses, their detachment from surrounding tissues, and their total resection. Complete resolution without postoperative complications was achieved in 43 cases (95.6%).
