title: [Preliminary clinical research with thoracic deformities in microtia].
abstract: OBJECTIVE
  To investigate the characteristics and incidence of the thoracic deformities in patients with microtia.
  
  
  METHODS
  In Plastic Surgery Hospital, we conducted a retrospective study of the clinical and radiographical data of 300 patients with microtia from March 2013 to October 2014. Pearson χ2 test was used to analyze the relationship among deformities of ribs and spine, as well as microtia.
  
  
  RESULTS
  A total of 78 (26.0%) patients were documented with rib deformities, 26 patients (8.7%) had spinal deformities, and 17 patients (5.7% )had both. The incidence of rib deformities in microtia I, II, and III was 7.1% (2/28), 26.7% (62/232) and 35.0% (14/40) respectively. The incidence of spinal deformities in microtia I, II, and III was 3.6% (1/28), 6.5% (15/232) and 25.0% (10/40 respectively. The patients with microtia III were found to have a higher incidence of ribs and spinal deformities than those with microtia II, patients with microtia II were found to have a higher incidence of ribs and spinal deformities than those with microtia I (P < 0.05).
  
  
  CONCLUSIONS
  The incidence of ribs and spinal deformities is high in patients with microtia. The poorer one auricle developed, the higher the incidence of thoracic deformities.
