title: First results of frontal sinus obliteration with a synthetic, resorbable and osteoconductive bone graft of ß-tricalcium phosphate.
abstract: BACKGROUND
  Despite advances in endoscopic sinus surgery, frontal sinus obliteration is still indicated in some cases. Current options for obliteration include autologous and synthetic materials. The use of ß-tricalcium phosphate as a resorbable bone graft substitute is a good alternative for frontal sinus obliteration. This study aimed to report our experience with this material.
  
  
  METHODS
  A retrospective chart review of patients who underwent frontal sinus obliteration at our clinic between 2008 and 2013 was performed. Demographic data, indications, previous surgery, and immediate and late complications were examined. Information on persisting symptoms and patient outcomes was collected using a telephone questionnaire in February 2016.
  
  
  RESULTS
  None of the patients underwent further surgery for frontal sinus disease. All of them reported a good cosmetic result and symptom improvement.
  
  
  CONCLUSIONS
  ß-tricalcium phosphate is a good, safe and cost-effective material for frontal sinus obliteration.
