Osteoma most often occurs in young people in the second and third decades, mostly in men. Osteoma can be treated surgically with an external approach or with an endoscopic approach. The surgical technique with an incision technique open rhinoplasty with transcolumella incision extensions is effective, because it can minimize surgical scars post-operative and correct the esthetic problems.
