Application of the tragus cartilage ring with perichondrium for tympanoplasty in chronic otitis suppurative media in the period of infection / 中国组织工程研究

ABSTRACT

Recently, the annulus cartilaginous-perichondrium made from tragus cartilage-perichondrium were successfully used as grafts in open tympanoplasty and myringoplasty, which showed distinctly better effect than that of fascia temporalis with no drum retract or ossicular chain conglutination and stable hearing. The article retrospectively analyzed long term effect of 150 patients which received tragus cartilage ring with perichondrium as grafts in myringoplasties and mastoidectomy with ? period tympanoplasty, and summarized the superiority and application value of the tragus cartilage ring with perichondrium for tympanoplasty in chronic otitis suppurative media in the period of infection.
