The presence of normal nasal and nasopharyngeal saprophytic flora is fundamental to maintaining the good health of the upper respiratory tract and the body. Disruption of the saprophytic flora can lead to the development of serious diseases in this area such as: frequent otitis media, rhinosinusitis, adenoiditis and predispose to complications of the lower respiratory tract. Various environmental factors, physical or chemical, can affect the composition of this delicate microbial ecosystem. Rinogermina is a medical device with mechanical action, designed to restore the natural biological barrier formed by the saprophytes living there and to reduce the surface tension of nasal secretions. Rinogermina is recommended: For the treatment and prevention of nasopharyngeal and tubal infections, such as: otitis media, adenoiditis, rhinosinusitis; after local nasal and/or frequent antibiotic treatments, to help restore normal nasopharyngeal
