Abstract
Tympanoplasties were performed on 107 blast-induced tympanic membrane ruptures. An air-bone gap of less than 10 dB, or a speech reception threshold of less than 30 dB was obtained on 80.6% of cases. An intact tympanic membrane was achieved in 86.9% of cases.

The most frequent form of ossicular abnormality was disruption of the incudomalleolar joint and adhesion of the malleus tip to the promontory. This occurred in approximately 25% of cases. Incudostapedial joint abnormality occurred in 8.4% of cases. Medial placement of graft material had both lower graft failure rate and better hearing result than lateral placement.
