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.

Methodology: 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.
