title: Correction of septal and midface hypoplasia in maxillonasal dysplasia (Binder's syndrome) using high-density porous polyethylene.
abstract: BACKGROUND
  Maxillonasal dysplasia (Binder's syndrome) is a congenital malformation characterized by an extremely flat and retruded nose.
  
  
  METHODS
  This report describes an 18-year-old woman with maxillonasal dysplasia (Binder's syndrome). The septal deficiencies and maxillary retrusion of the patient were corrected by using an L-shaped implant and a crescent-shaped high-density porous polyethylene implant through the oral vestibular sulcus via an external rhinoplasty approach.
  
  
  RESULTS
  After the operation, the tip of the nose had moved 5.5 mm anteriorly in the sagittal plane and 11.9 mm coronally in the vertical plane. Also, the nasolabial angle had increased after the surgery. Follow-up evaluation at 24 months showed good correction of the nasal and midface projection.
  
  
  CONCLUSIONS
  High-density porous polyethylene implants are a good alternative for patients with Binder's syndrome, especially those who will not accept costal cartilage grafts or orthognathic surgery and who have tendency for hypertrophic scarring.
