Utilizing electromyography and electrical muscle stimulation, the muscle responsible for opening the Eustachian tube was examined im 12 dogs. Different time values for tubal opening and levator activity indicate little contribution of the levator in the functioning of the tube. By relatively low stimulation of the tensor, the tube opened consistently, while the levator failed to produce any dilation of the tube, regardless of the amount of stimulation, in 6 dogs. Thus, it is concluded that the sole muscle responsible for tubal opening is the tensor, while the levator does not participate in the functioning of the tube.

“…The POP and PCP were determined by the forced-response test initially described by Flisberg et al 14 Time-pressure schematic demonstrates pressure changes within each eustachian tube function test session. After induction of anesthesia, we placed the rats in the right lateral recumbent position in order to visualize their left tympanic membrane (TM) with the operating microscope.…”

Gastroesophageal reflux is a common problem in the newborn and preschool periods. Recent research suggests that it may be related to eustachian tube dysfunction and otitis media with effusion. The purpose of this experiment was to investigate the relationship between simulated gastroesophageal reflux and eustachian tube dysfunction. Rat middle ears were repeatedly exposed (transtympanically) to pepsin in hydrochloric acid or to phosphate-buffered saline solution. Their eustachian tube function was evaluated by assessing passive opening and passive closing pressures, and active clearance of positive and negative pressure. The passive pressure function tests showed variable results. The rats exposed to pepsin in hydrochloric acid had an impaired ability to clear positive and negative pressure from the middle ear as compared to the rats exposed only to phosphate-buffered saline solution. The results demonstrate that multiple middle ear exposures to pepsin in hydrochloric acid leads to eustachian tube dysfunction in rats.

“…These include manometry [3,4], tympanometry [5], eustachian tube endoscopy [6,7], dye studies with fl uorescein [7,8] and saccharin [9] and sonotubometry [10]. The infl ation-defl ation test was fi rst reported by Flisberg et al [11]. It has been adapted for routine clinical use by Bluestone et al [5].…”
