The primary cause of otitis<unk>  is bacterial; the majority of cases result from Pseudomonas aeruginosa or Staphylococcus aureus infections. Otomycosis can cause otitis<unk>  with primary infectious fungi including Candida albicans and Aspergillus niger.

Contact dermatitis can cause otitis<unk>  from allergic reactions to cosmetic chemicals and metals. Rarely, psoriasis therapy secukinumab can cause otitis<unk>  as an adverse reaction.
