“…On the other hand, according to an animal study, the obstruction of the eustachian tube alone does not cause OME (9,10). For example, Proud et al (10) experimentally ligated the eustachian tube of cats, yet no cat suffered from OME.…”

“…The MIW of the maxillary sinus lies in close proximity to the natural ostium 3 ; any mucosal swelling or polypoid change in this area can result in partial or complete ostial occlusion. Complete obstruction of a mucous membrane‐lined space results in gas resorption and negative pressure formation 5‐8 . Low‐compliance walls collapse inward, and the remaining dead space is filled by an acellular transudate 9 .…”

Manometric Study of Complete Ostial Occlusion in Chronic Maxillary Atelectasis

1996

The effect of complete ostial occlusion on static pressure within the human maxillary sinus has not been previously studied. In this study, a novel way to directly determine maxillary sinus pressure is described. Maxillary sinus pressures were measured in five patients with chronic maxillary atelectasis (CMA); these values were compared to values obtained from the contralateral side and from patients with chronic sinusitis. Measurements were made by introducing an 18-gauge needle probe through the membranous fontanel of the maxillary sinus and recording the pressure value with an amplified, pressure-sensitive transducer. The average value recorded in five patients with atelectasis of the maxillary sinus and complete ostial occlusion was -8.4 +/- 2.6 cm H20 (mean +/- standard deviation). Static pressure measurements of the contralateral antrum were isobaric, as were measurements found in patients with chronic sinusitis. This study reports for the first time the sinus pressure of completely occluded maxillary ostia in patients with CMA. These results may improve our understanding of the development of ostial occlusion and its role in the pathogenesis of CMA and sinusitis.

“…The predominant findings were: (1) the loss of ciliated cells in the early stages (eight days) and (2) an increase in the number of dark-granulated cells. Histologic sections, however, indicated that only an incomplete occlusion of the tube was present.…”
