title: Treatment of severe sinus infection after sinus lift procedure: a case report.
abstract: Maxillary sinus floor augmentation may have a variety of postoperative complications including infection, sequestration of bone, and maxillary sinusitis. Complications can also occur due to a preexisting sinus condition called ostium stenosis. This case report presents a complication after sinus lift and grafting procedure due to an unrecognized ostium stenosis.
  
  
  METHODS
  A 50-year-old male patient had sinus augmentation on his right side. However, postoperatively, his symptoms were protracted. A CT scan showed thickening of the Schneiderian membrane and scattered graft material. Management included endoscopic nasal examination and ostium enlargement, antibiotic coverage, and full enucleation of the graft and diseased tissue.
  
  
  CONCLUSIONS
  Patency of the sinus ostium should be carefully evaluated before sinus lift/grafting procedure using CT technology. Radiology and otolaryngology consultations may be necessary to rule out ostium stenosis before surgery.
