[Laryngeal papillomatosis: A rare cause of dysphonia in the child. Case series].

Juvenile laryngeal papillomatosis is an uncommon disease caused by human papilloma virus, mainly types 6 and 11. It is the most common benign laryngeal tumor in children. This condition should be suspected in any children with persistent and progressive dysphonia with or without stridor and respiratory distress. Flexible laryngoscopy under local anesthesia allows to visualize the typical wart-like lesions. The diagnosis is confirmed by pathological anatomy. Existing treatment is palliative and consists mainly of the surgical excision of the papillomas to maintain the airway without obstruction and to improve the quality of the voice, but it has a high rate of relapse. We present 20 patients with juvenile laryngeal papillomatosis. We describe the clinical manifestations, the diagnostic methods and the treatment of this pathology.
