Abstract
Fifty-one patients suffering from inverted papillomas of the nose and paranasal sinuses were reexamined in a retrospective study. Thirty-five had undergone surgery by an intranasal endoscopic approach and 16 had undergone surgery by an extranasal approach. The recurrence rate following endoscopic interventions was 17% (6/35), as compared to 19% (3/16) after extranasal operations. Endoscopic surgery proved to be successful even in the treatment of large lesions affecting the posterior ethmoidal sinus, the nasofrontal duct, or the sphenoidal sinus. Its indication thus no longer needs to be restricted to limited lesions of the anterior nasal cavity. Patients with inverted papillomas will benefit from this surgical technique which remains minimally invasive and thus retains the paranasal bony framework, preserves unaffected mucosa capable of recovery, and prevents damage to the patients' cosmetic features.
