title: Surgical management of osteomas of the frontal recess and sinus: extending the limits of the endoscopic approach.
abstract: Osteomas are among the most common benign tumors of the paranasal sinuses. Symptomatic osteomas are most often found in the frontal recess and the frontal sinus. While the extranasal approach is still a part of the treatment concept for removing osteomas at this localization, over the last years the endoscopically controlled endonasal approach has greatly gained in importance due to the improved surgical equipment. We retrospectively analyzed the surgical indication, surgical approach and outcome of the removal of osteomas of the frontal recess and the frontal sinus performed at our hospital between 1996 and 2010. The exact surgical technique, intra- and postoperative complications, the duration of the hospital stay and the follow-up and subjective contentment of the patients were evaluated. With a total of 24 patients being included, the study comprises one of the largest groups of patients with osteomas of the frontal recess and sinus. Over the study period, the frequency of the endoscopic approach clearly increased. Previously suggested guidelines for the endoscopic resection of a frontal sinus osteoma turned out to be superseded. Endoscopically controlled resection even of large, adversely located osteomas of the frontal recess and the frontal sinus is becoming increasingly possible, but is still naturally limited by the individual anatomic conditions and the need for experienced surgeons.
