Abstract
Summary and conclusion
Background:
Tympanic perforation is associated with high morbidity rate to the affected cases, although many types of grafts were used for tympanoplasty, however cartilage graft widely used especially in patient with the atelectatic tympanic membrane and recurrent perforations due to The rigid nature of cartilage that effective in preventing retraction.
This study was done to evaluate hearing after cartilage tympanoplasty.
Conclusion
1. The anatomical success rate of cartilage tympanoplasty among our patients was 82.5%, this is somewhat low percentages compared with what written in literature, due to small number in our series.
2. 87.5% of our patients showed improvement in their air bone gap with a mean of 8.43 dB.
This study reveals that tragal cartilage shield tympanoplasty is a reliable technique, in fact it has a high degree of graft take and hearing results are satisfactory. Furthermore, the cartilage is a satisfactory grafting material because it is easily accessible, easy to adapt, resistant to negative middle ear pressures, stable, elastic, well tolerated by the middle ear, resistant to resorption
from the above we can say there is obvious improvement in the anatomical and functional outcome after cartilage tympanoplasty.
