“…The impact of this is probably small as other studies have shown that the main tubal function improvement in healthy individuals takes place at an early age [5,6,8,21,23]. In earlier studies of healthy adults, the distribution of tubal function groups was in accordance with that found in our controls [14,23].…”

“…In this group of young adults with earlier chronic SOM the tubal function seems not to have improved as much with age, as has been reported earlier in studies of healthy individuals [23]. The present study shows that, in spite of meticulous follow-up and appropriate treatment with transmyringeal ventilation tubes, tubal function problems may persist into adulthood, despite the fact that the patient is clinically healthy.…”

“…Interestingly, 13% of the ears in the SOM group had patulous tubes (compared to none in the control group), thus constituting a possible habitual sniffing group. In spite of the fact that some of those with patulous tubes may have good active tubal function, it was a remarkable contrast to the only 2-4% patulous tubes seen in studies of healthy adults [14,23]. It seems likely that the development of chronic SOM is related more to poor active pressure equilibration of the ME although the increased frequency of patulous tubes might give some support to the habitual sniffing theory.…”

Objective. Balloon eustachian tuboplasty (BET) has entered clinical use as a treatment for eustachian tube dysfunction. Some surgeons perform myringotomy prior to BET due to concerns that the increase in middle ear (ME) pressure caused by BET may cause otic barotrauma. We investigated the ME pressure changes occurring during BET in cadavers. Study design. Human cadaver investigation of a surgical techniqueSetting. Laboratory study at a tertiary referral center.Subjects and Methods. ME pressures were recorded from fresh-frozen cadavers, and BET was performed with the Bielefeld balloon catheter inflated to 10 bar. Peak ME pressures were recorded during catheter insertion, inflation, deflation, and removal. A second pressure measurement was taken 15 seconds after each stage to assess the residual pressures. All BET procedures were repeated at least once. Where transmastoid recordings were made, BET was repeated, measuring pressure via a myringotomy to ensure equivalence.Results. Data from 25 procedures in 13 ears (9 heads) were analyzed. A consistent pattern of ME pressure change was observed in all cases. Positive pressures occurred on insertion (maximum, 26 daPa) and inflation (maximum, 99 daPa) and negative pressures on deflation (maximum, -46 daPa) and removal (maximum, -42 daPa). There were no significant pressure differences between first and second procedures, except at 15 seconds after insertion (P = .04).Conclusion. In adult cadaveric specimens, BET induces ME pressures within the normal physiologic range. On this basis, routine myringotomy prior to BET in adults is not necessary.

“…The continuous absorption of oxygen through the mucosal lining in the middle ear space together with the variation of ambient barometric pressure constitutes the basic need for intermittent air exchange through the eustachian tube. This is accomplished by opening the tube and admitting air either from or into the middle ear space [1,2].…”

Eustachian tube is a bony and fibrocartilagenous tube extending from the antero-inferior part of middle ear cleft to lateral wall of the nasopharynx. Its main functions are ventilation of middle ear to equalize the middle ear pressure with atmospheric pressure and mucociliary clearance. The functioning of eustachian tube has a direct impact on normal middle ear function. As a corollary, dysfunction of eustachian tube inevitably leads to retraction of the tympanic membrane initially and sterile effusion and subsequent conductive deafness later. Secretory otitis media today is the most common cause of conductive deafness in children with an intact ear drum.
