RESUMO
PURPOSE: To report a series of 15 new cases of nasopharyngeal angiofibroma treated with presurgical embolization along with a review of the literature. MATERIALS AND METHOD: Retrospective review of 15 cases of nasopharyngeal angiofibroma treated with presurgical embolization. The clinical, CT and MR features as well as postsurgical follow-up are reviewed. RESULTS: Presurgical embolization reduced surgical difficulties, especially hemorrhage, allowing complete tumor resection in most cases. Two cases of recurrent disease and 1 case of residual tumor were noted and treated by repeat embolization. CONCLUSION: Presurgical embolization reduces intraoperative hemorrhage and allows complete resection of these highly vascularized tumors.

Le kyste de la vallecule est une malformation laryngee rare pouvant parfois mettre en jeu le pronostic vital. Diagnostique et traite a temps; le risque de complications et de morbidite peut etre ecarte. Les auteurs rapportent 2 cas de kystes de la vallecule. La tomodensitometrie a confirme la presence d'une formation kystique prenant origine au niveau de la vallecule. Une laryngoscopie directe a ete faite pour les 2 patients sous anesthesie generale. Le premier malade a eu une resection endoscopique complete du kyste et le 2eme une large marsupialisation au Laser. L'examen anatomopathologique a confirme la benignite de la formation kystique dans les 2 cas
