Abstract
We investigated the usefulness of mesh-type nebulizers in nasal diseases. This experiment was conducted in two adults with no nasal diseases. We used two mesh type nebulizers (OMRON Micro Air NE-U22®, and PARI eMotion®) with attached nasal nozzles in this nuclear medicine study. Aerosols nebulized by the OMRON Micro Air NE-U22® were widely distributed in the nasal cavity, whereas aerosols nebulized by the PARI eMotion® were distributed in the throat and trachea in addition to the nasal cavity. Based on this experiment, it appeared that differences in the distribution of aerosols were due to the total output rate. As this experiment used a nasal nozzle, the deposition rate of the aerosols may have differed. When a nasal nozzle is used on a mesh-type nebulizer, the shape of the nozzle needs to be considered.
