[Long-term effect of the modified type-III tympanoplasty].
Tympanoplasty using reconstructed ossicular chain from auto and foreign rib cartilages were performed on 264 ears with missing malleus. The postoperative follow-ups have been made in 102 ears with auto cartilage for 5-6 years and in 162 ears with foreign cartilage more than 4 years. The hearing level of 79 ears in the former (77.4%) and 124 ears in the latter (76.5%) have been enhanced by 15 dB or to applied hearing level. Long-term hearing improvement was satisfactory. The characteristics of the surgical methods was discussed.
