“…Subjects with cholesteatoma also had a shorter ET length than subjects with retraction pockets. Paltura et al [11] evaluated 232 subjects with unilateral COM. The mean width of the ET isthmus was 19.47±0.52 mm for healthy ears and 17.88 ±0.53 mm for diseased ears, which showed a significant difference.…”

Objective: To compare intact and diseased ears for Eustachian tube (ET) length and width in patients with unilateral chronic otitis media (COM), and to assess the relationship between cholesteatoma spread, stapes erosion, lateral semicircular canal (LSCC) fistula and ET width and length retrospectively. Methods: Subjects with unilateral COM (122 subjects with 244 ears) who underwent surgery for cholesteatoma were evaluated retrospectively for this study. The width of the distal orifice of the bony segment and the length of the bony segment of the ET for both the diseased and healthy ear were measured. Subjects' healthy and diseased ears were compared for ET length and width. The diseased sides were compared to assess the relationship between ET dimensions and cholesteatoma spread, stapes erosion and LSCC fistula. Results: The mean ET length and width in healthy and diseased ears was 11.38±1.7 and 1.43±0.37 mm, and 10.99±1.6 and 1.27±0.35 mm, respectively; the difference was statistically significant (p<0.001). No significant differences were found in terms of ET length and width between the subjects with and without stapes erosion and LSCC fistula (p=0.765, p=0.573, and p=0.436, p=0.790, respectively). No significant relation was found between cholesteatoma spread and ET length and width (p=0.647). Conclusion: ET dysfunction is frequently associated with COM. Chronic otitis media with cholesteatoma is significantly related to ET length and width. Measurement of ET length and width in CT scans is a basic method that can be used in clinical practice.

“…We reviewed cases of nasopharyngeal localized amyloidosis in the literature from 1980 till today. We found 5 cases of patients with reported Eustachian tube dysfunction or middle ear effusion [6][7][8][9][10]. Interestingly, cases of (massive) nasopharyngeal amyloidosis without tube dysfunction have also been described [14,15].…”

“…In most cases, dilatory tube dysfunction is a continuous problem [7]. The underlying factors for a dilatory tube dysfunction can be extrinsic, such as a nasopharyngeal mass obstruction of the pharyngeal Eustachian tube orifice or obstruction of the bony portion of the Eustachian tube [8]. Dilatory tube dysfunction can also be caused by intrinsic factors, e.g., an acute or chronic mucosal swelling in the nasopharynx, pharyngeal Eustachian tube orifice and mucosa due to an allergic reaction, gastroesophageal reflux disease, and chronic inflammation [9].…”

“…It has previously been suggested that a decrease in junction diameter might be an independent factor in the development of chronic otitis media. 9 Another study claimed that the thickened mucosa of the bony segment and Eustachian tube orifice in the middle ear may act as a barrier to middle ear ventilation and thus, might be the key factor in Eustachian tuboplasty failure and this view has been supported by other studies. 7,10,11 However, radiological studies have stated that the osseous portion of the ET is not frequently and obviously involved in this process.…”
