title: Endonasal endoscopic excision of a rare tumor: nasal bone osteoid osteoma.
abstract: BACKGROUND
  Osteomas are slow-growing, benign tumors that frequently occur in paranasal areas; are detected by their symptoms, depending on their location and size, or incidentally on radiologic examination; and rarely arise from the nasal bone. We present an isolated nasal bone osteoma--which has not, to our knowledge, been reported previously--that was excised using an endoscopic endonasal approach via intercartilaginous incision and reconstructed with MEDPOR.
  
  
  METHODS
  A 21-year-old male patient attended the Mardin State Hospital ENT Clinic with the complaint of a slowly enlarging mass on the left side of the nose. The clinical, radiologic, and histologic findings pointed to a diagnosis of nasal bone osteoma.
  
  
  RESULTS
  An endoscopic-assisted endonasal approach was performed, and defect was reconstructed with MEDPOR. At postoperative 6-month evaluation, no recurrence was observed, and the cosmetic result was satisfying in both external and intranasal views.
  
  
  CONCLUSIONS
  In the removal of rare nasal bone osteomas, endoscopic endonasal surgery could be preferred over an external approach because of its favorable cosmetic results, comfort for the patient, and graft viability.
