“…In the literature, ET structure (length, width and angle) has been investigated in different studies. Dinç et al [10] evaluated the ET angle and length of diseased and healthy ears of 125 subjects. Diseased ears were those with different kinds of chronic suppurative otitis media (CSOM) (retraction pockets, central perforation, tympanosclerosis and cholesteatoma).…”

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 detected no significant difference between the patient and control groups according to age and gender. In the literature, there are studies investigating the ET length and angle [16][17][18], ETC amount according to age groups [16], cartilage cell density in relation to age [19], and cartilage elastin amount and volume [20][21][22]. Most similar to our work related to the measurement of the ET medial laminal thickness is the study undertaken by Amoodi et al [23].…”

Purpose: The purpose of this study was to prospectively assess the Eustachian tube (ET) cartilage using 3 Tesla (3T) magnetic resonance imaging (MRI) and compare the results between healthy ears and those with a middle ear disease. Material and methods: The study included 56 ears with a middle ear disease as the patient group and 100 ears without a middle ear disease as the control group. The patients' age ranged from 18 to 65 years. The axial three-dimensional (3D) multiple echo recombined gradient echo (MERGE) sequence and oblique parasagittal planes were obtained. Visualisation of the ET cartilage was assessed on the MR images using a three-point numerical rating score. In the axial plane, the ET lumen's diameter was measured from the mid-portion of the cartilage. Results: There was no significant difference between the patient group and the control group according to patients' age and gender, and the medial laminal thickness of the ET cartilage. In the patient group, the diameter of the ET cartilage was significantly smaller than in the control group. The ET lumen diameter was significantly lower according to each of the three scoring systems. Conclusions: 3T MRI provides an evaluation of the ET cartilage and isthmus level, which are small but important anatomical localisations and surgical landmarks. MR imaging has the potential to provide essential information on ET prior to new surgical treatments, such as balloon dilation for middle ear diseases.

“…The same results were also obtained in this study, where the angle of Eustachian tube in men is more horizontal than in women and the number of patients with CSOM in men more than women. Dinc (2015) in Turkey reported the Eustachian tube angle was significantly more horizontal in men than in women. This causes more men suffer from CSOM with cholesteatoma.…”

“…A more horizontal angle of the Eustachian tube causes otitis media to occur frequently in children. Recurrent acute otitis media (AOM) or otitis media effusions (EOM) that last a long time in childhood will cause the CSOM in adulthood (Dinc, 2015).…”

The Diffrentiation of the Angles of Eustachian Tubes In the Patient Chronic Suppurative Otitis Media With and without Cholesteatoma

Background: Chronic Suppurative Otitis Media (CSOM) is one of the major health problems found in many populations in the world and a cause of high morbidity and high mortality. However, there is no single theory that explains how and why chronic otitis media occurs. There are many studies on the function of Eustachian tube. However, the role of the Eustachian tube angle and the relationship with the occurrence of CSOM has not been widely studied. This study aimed to evaluate the mean of Eustachian tube angle and to examine the diffrentiation between angle of Eustachian tube in Chronic Suppurative Otitis Media (CSOM) patient with and without cholesteatoma. Subjects and Methods:This research is a case-control study. Study group consist of 27 patients of CSOM with cholesteatoma and 27 patients of CSOM without cholesteatoma included as controlling. All patients are examined by using CT temporal and measured the angle of Eustachian tube using Multiplanar Reconstruction (MPR) technique on osirix program. The data was analyzed using independent T test Results: The mean of the Eustachian tube angle in CSOM with cholesteatoma in female patients was 28.69 0 and male 27.78 0 whereas in the CSOM group without cholesteatoma in female patients was 33.81 0 and men 31.87 0 . The mean of Eustachian tube angle in CSOM patients with cholesteatoma is 28.22 0 and CSOM without cholesteatoma is 33.00 0 . In independent T test, the result showed significant differentiation (p= 0.001) between the angle of Eustachian tube in patients CSOM with and without cholesteatoma. Conclusion: The advance of technology makes easier to measure of Eustachian tube angle. In men found that the Eustachian tube angle is more horizontal than women. There is diffrence between the angle of the Eustachian tube with the occurrence of cholesteatoma in CSOM.
