Novel device superior to traditional rinse bottle for nasal irrigation in sinonasal diseases

The key findings of this study were as follows:

1. The irrigation flow of a long nozzle with a side aperture differed from the irrigation stream of the nasal vestibule exit.

2. The innovative gadgets demonstrated a continuous water stream directed directly upwards to the anterior region of the olfactory cleft. When the cast was watered with 120 ml or 175 ml water, the new devices easily achieved an irrigation efficiency of 100 percent depending on different head locations.

3. When the cast was irrigated with 240 ml water beneath each head position for the rinse bottle, there was still a minor bit of yogurt remaining in the olfactory cleft.

4. The irrigation efficiency was volume-dependent, with the rinse bottle's average irrigation efficiency at 240 ml only reaching 69.1%.

In conclusion, Nasal irrigation efficiency is enhanced by a continuous water stream directed upwards to the anterior region of the olfactory cleft, paired with an expanded nozzle that overcomes the flow-limiting effect of the nasal valve. More research is needed to evaluate therapy efficacy, patient comfort, and safety in the clinical context.
