The purpose of this study was to determine whether an in vitro model could be developed to assess TT plug formation with results consistent with human trials. STUDY DESIGN An ear chamber was designed to mimic middle ear air and mucus flow conditions in post-TT otorrhea. TT occlusion was tested and ...
