[Laryngeal Papillomatosis In Niamey: Epidemiological, Diagnostic And Therapeutic Aspects].

Abstract

Objective: to present the epidemiological, diagnostic, therapeutic and progressive aspects of laryngeal papillomatosis.

Patients and method: This was a retrospective study over a period of 6 years (January 2016 to December 2021), covering cases of laryngeal papillomatosis collected at the Oto-Rhino-Laryngology department of the Niamey National Hospital.

Results: A total of 36 cases of laryngeal papillomatosis were recorded. The average age of the patients was 19 years. Children aged 0 to 15 were the most represented with 23 cases (63.89%). The symptomatology was dominated by dysphonia in all patients, associated with dyspnea in 97% of cases. The average duration of progression of these symptoms was 16 months. Direct suspension laryngoscopy made it possible to make the diagnosis in all cases and to proceed with surgical excision of the papillomatous tufts using micro-instruments. The tracheotomy preceded that endoscopy in 7 cases (19,44%). The evolution was marked by recurrence observed in 17 cases (48.57%).

Conclusion: Laryngeal papillomatosis is a rare condition in ENT in Niamey. It is characterized by a delay in diagnosis. Endoscopic micro-tweezer peeling was the therapeutic modality used, the evolution of which remains punctuated by recurrences.
