Introduction: To describe the epidemiological profile of patients with laryngeal papillomatosis, to identify diagnostic aspects and evolution after treatment.

Method: This was a retrospective study over 16 years, from May 1995 to April 2011, in the ear nose throat in Hubert Koutoukou Maga, National Teaching Hospital of Cotonou. It was based on descriptive analysis of medical record together with operation report of patients.

Results: We have sampled 18 patients, 1.12 case/year. The sample included 10 males and 8 females with a frequency of 0.55 in favor of males. The average age was 6.95 year old and children in school or about to be in school were 14. The time-frame between the beginning of symptoms and consultation was 1.17 years. During the endoscopy, the lesions in grains or clusters sometimes obstructive acting as seat on the larynx were confirmed at pathologic check-up. The treatment consisted of peeling all of them with an average of 4.6 (1-23) associated with the local whitewashing by mitomycin in 3 cases. A tracheotomy rescue had to be performed urgently (12 cases). The monitoring was effective in 14 cases over an average of 14.85 months (3 months-175 months). Ten (10) patients had both normal voice and breathing. In 3 cases the patients had suprasternal draw supine and intermittent dysphonia after decanulation. In a case the weaning could not be achieved. The complications were related to the peeling, to tracheotomy, and to the presence of the cannula.

Conclusion: Laryngeal papillomatosis is a common pathology in children. It is easy to diagnose this pathology, but this raises recurrent therapeutic problems such as education disrupti
