    The nasal tip occupies important position in rhinoplasty in Asian because Asian tip has features of round or bulbous shape, lower height and wider base compared with that of Caucasian. The hardness of the nasal tip may increase during the course of a routine rhinoplasty by maneuvers such as incising or excising cuts into the lower lateral cartilage, suturing, and grafting of cartilages. Also, change of hardness may be a component of postoperative dissatisfaction. But, there is no device to measure hardness of nasal tip. We developed "nasal tip durometer" using Teclock Durometer GS series 701 G. The spring rate of Teclock Durometer was converted from 0.223kgf/mm to 0.036kgf/mm to apply to human body. After the remote air switch was fixed to apply with the same speed in patient's nose, we manufactured frame so that can attach to surgical operation table. The reliability, validity, and responsiveness to clinical change of our durometer were evaluated in a clinical study to 20 patients. Our durometer was highly reliable(Spearman correlation coefficient, r=0.95), valid(Spearman correlation coefficient, r=0.85), and responsible(effect size=11.37). We concluded that nasal tip durometer was useful to measure the hardness of the nasal tip objectively.
