Device Study to Evaluate the Detection and Characterization of Middle Ear Fluid in Children


The study has three objectives: 1. To determine if the device can detect if middle ear fluid is present in children who are scheduled for tube placement (myringotomy) 2. If fluid is present to characterize the fluid as thick or thin 3. Evaluate the safety of the device
