On Pressure Regulation of the Middle Ear

Ventilation and Gas exchange in middle ear ( R 716 ) ID : 716 . 2 The role of the mastoid in middle ear pressure regulation Presenting

Learning Objectives: Recent studies on the mastoid structure and function has pointed to an important role in middle ear physiology. The normal function of the middle ear depends on regulation of its pressure relative to ambient pressure, and traditionally gas exchange between the middle ear mucosa and gas pocket has been focused on together with the function of the Eustachian tube. However, re...

Effect of Suctioning of the Middle Ear Effusion on Hearing Condition Before Ventilation Tube Insertion

Abstract OME is a Common disease in children. over than 90% of children in preschool ages experienced this disease once at least. Despite medical therapy about 10% of the OME patients won't improved and these are the group of patients who referred to as chronic OME patients. Insertion of VT in TM is an accepted therapy for these patients and during surgery for insertion of VT, suctioning of mi...
