Relationship Between the Electromyographic Activity of the Paratubal Muscles and Eustachian Tube Opening Assessed by Sonotubometry and Videoendoscopy

Abstract

The mTVP activity had a shorter duration but greater amplitude than the mLVP activity and was associated with peak ET opening by sonotubometry. The mLVP activity occurred before that of the mTVP, the submental muscle group, and peak ET opening. The mLVP contractions were associated with movements of the soft palate, anterior ET orifice, and rotation of the ET cartilage.
