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 postprocedural 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.
