TI  - Hearing results with cartilage tympanoplasty.
PG  - 1094-9
AB  - Cartilage has shown promise as a graft material to close perforations in the 
      tympanic membrane (TM), particularly in cases of advanced middle ear pathology. 
      Although it is similar to fascia, its more rigid quality tends to resist 
      resorption and retraction. However, it is this rigid quality that has led many to 
      anticipate a significant conductive hearing loss when using cartilage to 
      reconstruct the TM. Because little has been reported in the literature comparing 
      hearing results using cartilage with results using other grafting materials, this 
      retrospective study was conducted to compare the hearing results of patients with 
      cartilage tympanoplasty with results in patients who underwent revision 
      tympanoplasty using perichondrium. Both series of patients had undergone type I 
      tympanoplasty, and the middle ear pathology was considered to be similar between 
      the two groups. TM closure was achieved in all 22 patients undergoing cartilage 
      reconstruction, but three of the 20 patients undergoing perichondrium 
      reconstruction had a recurrent perforation during the follow-up period 
      (approximately 1 year). The average pre- and postoperative pure-tone average 
      air-bone gap (PTA-ABG) was 21.1 dB and 6.8 dB for the cartilage group and 17.9 dB 
      and 7.7 dB for the perichondrium group, respectively. These gains in hearing were 
      statistically significant (P < 0.001 in each case), but there was no 
      statistically significant difference in hearing results between the two groups. 
      Analysis of the PTA-ABG as a function of percentage of TM reconstructed showed no 
      statistically significant difference in hearing results due to percentage of 
      cartilage used. These results indicate that cartilage tympanoplasty offers the 
      possibility of a rigorous TM reconstruction with excellent postoperative hearing 
      results.
