title: [Scalp surface skin grafts in reconstruction of external auditory meatus in congenital aural atresia].
abstract: OBJECTIVE
  To investigate the clinical application of scalp skin grafts in reconstruction of external auditory meatus in congenital aural atresia.
  
  
  METHODS
  We conducted a retrospective study on 85 patients of congenital aural atresia, all of whom were unilateral, operated from March of 2008 to December of 2010 in ENT department of the Sun Yat-Sen Memorial Hospital. The patients enrolled in the study were between 6 to 37 years old (median age 12 years), 55 male and 30 female. Scalp surface graft in ipsilateral temporal region was harvested to cover the bony external auditory meatus.
  
  
  RESULTS
  All of these scalp split-thickness skin grafts survived without necrosis, no restenosis was found in these external auditory meatus. Neither scar nor alopecia was found in the skin-harvesting region, and hairs grew well. Granulations occurred in 27 cases in the first to sixth month posteroperatively, 20 cases recovered after local treatment. In the first year, 30 cases obtained hearing improvement more than 15 dB, 36 cases gained more than 25 dB and 19 cases gained more than 35 dB. Totally 8 patients were lost in the 4 to 5 years of follow-up, 70 cases (70/77, 90.9%) developed new external auditory meatus, 7 cases (7/77, 9.1%) suffered from stenosis in different degrees, but no atresia was found in these patients.
  
  
  CONCLUSIONS
  Scalp split-thickness skin grafts has significant clinical advantage in meatoplasty of congenital aural atresia.
