title: [The treatment method and effect of orbital floor defects repaired with autologous tragus cartilage through Cald-well-Luc approach under nasal endoscope].
abstract: OBJECTIVE
  To explore the operative method and effect of fracture of orbital floor defects repaired with tragus cartilage through Cald-well-Luc approach under nasal endoscope.
  
  
  METHODS
  Fifteen cases suffered fracture of orbital floor defects(blow out fracture) were analyzed retrospectively. Oral vestibular incision were done directly to tip teeth kennel, maxillary sinus anterior forewall was chiseled with 2 cm x 2 cm size, orbital floor fracture defect size was probed under nasal endoscope, and the fracture of orbital floor defects was repaired with tragus cartilage.
  
  
  RESULTS
  Fifteen cases were successfully operated and no cases showed vision loss,diplopia, enophthalmos obviously after operation,while 3 case were a little eyeball limitation of activity and restored basically after one month. With two years of follow up, there were no spurious eyelid drooping, up-eyelid lacuna deepen, eyelid diameter shorten and facial deformity were found. Both eye-balls were basical symmetry and no complications were happened.
  
  
  CONCLUSIONS
  It is a satisfactory, effective and aminimally invasive surgical method without facial scars and eyelid ectropion for fracture of orbital floor defects repaired with tragus cartilage through Cald-well-Luc approach under nasal endoscope.
