Brief summary

The purpose of this post-market clinical investigation is to assess in a real-life setting, the effectiveness, usage, tolerance, safety and satisfaction of 4 isotonic and hypertonic seawater-based CE-marked nasal sprays. The main questions it aims to answer are: * Efficacy, * Safety, * Usage, * Satisfaction, in real-life usage among infants, children, adults and pregnant or breastfeeding women suffering from acute and chronic sinonasal pathologies. The 4 medical devices under investigation will be used in accordance with their intended use, target populations and medical indications.
