title: [Endoscope-assisted repair of pediatric blowout fractures of orbital floor with autologous bone fragment].
abstract: OBJECTIVE
  To explore the clinical efficacy of endoscopic repairing pediatric blowout fracture of orbital floor with autologous bone fragment.
  
  
  METHODS
  A total of 12 cases with blowout fractures of orbital floor between March 2010 and June 2012 at Third Hospital of HeBei Medical University were reviewed. They underwent nasal endoscopic reconstruction of autologous bone fragment in situ. Medicinal biomaterial glue was used for fixation. A 6-month follow-up was performed and the therapeutic efficacies of anatomic and functional recovery were evaluated.
  
  
  RESULTS
  No further vision loss or infection occurred postoperatively. Diplopia disappeared over a period of 3 days to 6 months. At 3 months post-operation, diplopia vanished completely (n = 9), and peripheral vision diplopia persisted (n = 3). Only 1 case had still peripheral vision diplopia at 6 months. Enophthalmos: ≥ 2 mm (n = 1), 1 mm (n = 3) for one week after surgery and only 1 mm (n = 1) at one month follow-up. Passive traction test was negative in all cases and computed tomograph (CT) revealed no bone redislocation postoperatively.
  
  
  CONCLUSIONS
  Endoscopic repair of pediatric blowout fracture of orbital floor with autologous bone fragment in situ is both effective and safe.
