This study was conducted to determine the deferential impact of cartilage myringoplasty on hearing thresholds at different frequencies. (juniperpublishers.com)
there is scarcity in researches that precisely analyze the impact of every method and graft on the different frequencies of hearing thresholds. (juniperpublishers.com)
Detailed analysis of hearing results of cartilage plate myringoplasty at each frequency is very important because it will reveal many facts about biomechanics of the middle ear and mechanisms of hearing loss such as the impact of mass loading and change of stiffness of middle ear mechanics on hearing thresholds at different frequencies [ 4 ]. (juniperpublishers.com)
In literature, mass loading o the tympanic membrane affects the low frequency air conduction hearing thresholds up to 1000 Hz while increasing stiffness of the middle ear mechanisms makes the high frequency air conduction hearing thresholds to increase [ 5 ]. (juniperpublishers.com)
Consequently, neither the mass nor the stiffness of the graft in cartilage myringoplasty has any effect on hearing thresholds [ 6 ]. (juniperpublishers.com)
So that it is very important to analyze hearing results of cartilage myringoplasty in details, using highly sensitive pure tone audiometer to determine which frequencies are maximally corrected by this heavy and stiff graft. (juniperpublishers.com)
