Abstract

This clinical pilot study aimed to assess the clinical effectiveness of a newly developed device, Smart Naso^TM, for resonance disorders and compare its performance with that of the Nasometer II 6450. A group of 18 total participants (nine each in normal and hypernasality groups) were examined using the VIP inspection and K SNAP Test while wearing Nasometer II 6450 or Smart Naso^TM, and the reliability of the new device and similarity of both devices were evaluated. When the newly developed Smart Naso™ and Nasometer II 6450 were applied to the hypernasality group, similarity was observed (Smart Naso^TM: 0.776–0.989, Nasometer II: 0.922–0.996). In the test–retest reliability evaluation, both devices were found to be highly effective and reliable in the hypernasality group (Smart Naso^TM: 0.948, Nasometer II: 0.953); the Smart Naso^TM was found to be similarly effective and reliable for clinical applications. Smart Naso™ exhibited comparable effectiveness to that of Nasometer II 6450 and exhibits clinical utility for patients with hypernasality and those diagnosed with cleft lip and palate, cleft palate, and submucosal cleft palate.
