QUANTIFYING NASAL WALL CARTILAGE STIFFNESS: THE DEVELOPMENT OF A NASAL CARTILAGE CALIPER

Nasal obstruction is a widespread issue in the US, with dynamic collapse during inspiration being a common cause. Current treatment methods using radiofrequency lack precise quantification of nasal cartilage strength and rely on subjective measures such as QOL surveys. This study introduces a novel approach employing custom-designed nasal cartilage calipers with off-the-shelf electronics, offering a lightweight, accurate measurement of nasal cartilage stress-strain relationships based on force and distance. The graphical representation of real-time deformation and pressure provides a specific assessment compared to traditional rhinomanometry, aiding physicians in evaluating nasal cartilage strength and assessing post-procedural changes. Future iterations should address limitations and include comparisons with rhinomanometry, enhancing the device's utility in clinical settings. This innovative device addresses a critical gap in current medical practices by contributing to treatment decision-making and advancing nasal cartilage research.
