Pathology of the Eustachian Tube

Distribution of Mucus-Secreting Cells in Normal Middle Ear Mucosa

“…When these "glands" (cystic formations) are numerous, the lamina propria are, without exception, extremely thick, indicating previous inflammation. 39 Since the middle ear cavity is always open to the air through the eustachi¬ an tube, the middle ear epithelium is expected to be inflamed on numerous occasions. Therefore, this "gland" formation should be looked upon as evidence of past inflammation.…”

Rapid cell population identification in flow cytometry data

“…Elimination of turbulent flow in the posterior nasal cavity by turbinectomy, as previously described, may also contribute to the restoration of normal mucosal function. Additionally, the fibrocartilage histology of the ET differs from the hyaline cartilage found in other anatomic lumens such as the laryngotracheal airway 22. This tissue may possess unique properties that allow it to retain a new configuration after dilation.…”

Tympanometry, a Prognostic Indicator of Myringoplasty with Assessment of Eustachian Tube Function

“…The tubal dysfunction is one of the most important factors responsible for the failure of reconstructive middle ear surgery-Zollner, 1963 [1], wullstein, 1963 [2], Farrior, 1965 [3], Schuknecht, [4] and Kerr, 1967 [4]. Even recently Toss [5] and Biswas [6] 1999 have emphasized the importance of Eustachian tube function in the middle ear surgery. The Eustachian tube function has been implicated in tympanoplasty failure both primarily via middle ear pressure dynamics and secondarily via recurrent otitis media Scott et al [7].…”
