title: [Surgery of paranasal sinuses: evaluation and follow-up of 239 patients operated on by microendoscopy].
abstract: Endoscopic surgery has progressed in the 90's, improving many surgical procedures in several specialties, among which, the ENT has been one of the most favored. In the present work we review the clinical features, surgical results and follow up of 239 patients who underwent microsurgery and endoscopic surgery of paranasal sinuses. All the patients were treated with a combined microscopic/endoscopic surgical procedures for recurrent or chronic sinusitis and/or nasosinusal polyposis. We performed 349 surgical procedures in 239 patients: 140 etmoidectomies, 194 procedures in the maxillary sinuses, 12 in the frontal sinuses and 3 in the sphenoidal sinuses. All the patients received previous medical treatment without positive results. Minor complications were present in 2% of the patients and major complications in 1.4% of the patients, that were solved in the immediate postoperatory. Follow up was made in 83% of the cases for a mean period of 20 months (range 12 to 48 months). Good results were obtained in 94% of the patients with chronic or recurrent sinusitis and in 82% of the patients with nasal polyposis.
