Comparison of a microsliced modified chondroperichondrium shield graft and a temporalis fascia graft in primary type I tympanoplasty: A prospective randomized controlled trial.

We conducted a prospective, randomized, controlled trial to compare outcomes in type I tympanoplasty patients who received an autologous microsliced modified cartilage perichondrium shield graft (cartilage group) and those who received an autologous temporalis muscle fascia graft (fascia group). Our three outcomes measures were (1) anatomic success rates at 3 months, (2) hearing results at 6 months, and (3) rates of morphologic success (i.e.
