Abstract
To provide a thyroid cartilage fixation device with a novel configuration that can suppress fracture. [Solution] The thyroid cartilage fixation device is a thyroid cartilage fixation device used in type 2 thyroplasty, and comprises an anterior piece positioned from the cut end surface of the incised thyroid cartilage to the anterior surface and a posterior piece positioned on the posterior surface of the thyroid cartilage, and comprises a plurality of clamping parts that fit onto the respective cut ends of the thyroid cartilage facing each other, and a bridging part that connects the plurality of clamping parts, and the bridging part has a plurality of pores that are dispersed substantially uniformly so as not to form clusters among adjacent pores, and the porosity of the pores formed in the bridging part when viewed from the entire bridging part is 0.5 to 4.5%.
