[Fungal otitis in Libreville. Study of 83 cases].

83 cases of mycotic otitis of external ear are reported during a period of 27 months from three departments of otorhinolaryngology in Libreville (Gabon, Central Africa) Prevalence is estimated at about 25% among all infectious otitis. The main functional signs are pruritus, otorrhea, pain and hypoacousia. The physical examination shows masse of white, grey, black or creamy caseous debris, invading the external auditory meatus (EAM) which is sometimes inflammatory. Fungal species responsible of otitis are Aspergillus (54%), yeasts (45%) mainly Candida, infrequently Fusarium (1%). A niger (26%), A. flavus (17%), Candida parapilosis (18%), Candida albicans (9%) are predominant species isolated (70%) among all the 21 species of identified fungi from otomycosis in Gabon. Therapy, done by thorough washing of the ear followed by insertion into the EAM of a wick soaked in Econazole or Amphotericin B, is quickly effective.
