Differences in Average Angle of Eustachian Tubes in Chronic Suppurative Otitis Media Patients with and Without Cholesteatoma Based on Temporal CT-Scan at H. Adam Malik Hospital Medan

Introduction

Chronic Suppurative Otitis Media (CSOM) is a significant health problem affecting various populations worldwide, resulting in high morbidity and mortality rates. One of the contributing factors to the occurrence of CSOM is dysfunction in the Eustachian tubes. The more horizontal Eustachian tubes can cause dysfunction and cleaning disorders of the middle ear. This study aims to evaluate the average tubal angle of the Eustachian and check the difference in angle in CSOM patients with and without cholesteatoma.

The Importance of Eustachian Tubes in CSOM

The Eustachian tubes play a crucial role in maintaining the middle ear's homeostasis by regulating the pressure and ventilation of the middle ear. Dysfunction of the Eustachian tubes can lead to the accumulation of fluid in the middle ear, resulting in CSOM. The angle of the Eustachian tubes is a critical factor in determining their function. A more horizontal angle can lead to dysfunction and cleaning disorders of the middle ear.

Research Methods

This study uses a case-control study design involving 54 patients, of which 27 patients are CSOM sufferers with cholesteatoma, and 27 other patients are controls suffering from CSOM without cholesteatoma. All patients undergo examination using temporal CT-scan, and the Eustachian tube angle is measured by multiplanar reconstruction techniques using the Osirix program.

Research Results

The results showed that the average tubal angle of Eustachius in CSOM patients with cholesteatoma was 28.32 °, whereas in CSOM patients without cholesteatoma was 33.03 °. In more detail, in the group of CSOM patients with cholesteatoma, the average tubal angle of Eustachius in female patients is 28.79 °, while in male patients are 27.88 °. On the other hand, in the CSOM group without cholesteatoma, the average tubal angle of the Eustachian in female patients is 34.65 ° and in men is 31.91 °.

Analysis using an independent T test shows a significant difference (p <0.05) between the average tubal angle of the Eustachian in CSOM patients with and without cholesteatoma.

Discussion

This finding shows that modern technology, such as CT-Scan, has facilitated the measurement of the Eustachian tubal angle with high accuracy. Interestingly, this study also found that in men, the corner of the Eustachian tubes tends to be more horizontal than in women. This may be caused by differences in anatomy and physiology between men and women, which can affect the way and effectiveness of the function of Eustachian tubes.

The difference in the tubal angle of the eustachian between patients with and without cholesteatoma can provide additional insights on pathogenesis and CSOM management. It also shows the need for more appropriate treatment for patients with cholesteatoma to prevent further complications that can endanger the health of the middle ear.

The Significance of Cholesteatoma in CSOM

Cholesteatoma is a type of skin cyst that can occur in the middle ear, leading to destruction of the surrounding bone and tissue. The presence of cholesteatoma can lead to further complications, such as hearing loss, vertigo, and facial paralysis. The difference in the tubal angle of the eustachian between patients with and without cholesteatoma can provide additional insights on the pathogenesis of cholesteatoma and its management.

Conclusion

This study revealed a significant difference in the corner of the Eustachian tube between CSOM patients with and without cholesteatoma. This finding provides a basis for further research and developing more effective handling strategies in dealing with this health problem. As a step forward, it is essential to continue broader studies to explore the factors that influence the function of the Eustachian tubes and their implications for CSOM.

Recommendations for Future Research

Future studies should focus on exploring the factors that influence the function of the Eustachian tubes, such as anatomy, physiology, and genetics. Additionally, studies should investigate the relationship between the tubal angle of the Eustachian and the development of cholesteatoma. Furthermore, studies should aim to develop more effective treatment strategies for patients with cholesteatoma to prevent further complications.

Limitations of the Study

This study has several limitations, including the small sample size and the use of a case-control study design. Future studies should aim to recruit a larger sample size and use a more robust study design, such as a cohort study or a randomized controlled trial.

Implications for Clinical Practice

This study has several implications for clinical practice. Firstly, it highlights the importance of accurate measurement of the Eustachian tubal angle using modern technology, such as CT-Scan. Secondly, it emphasizes the need for more appropriate treatment for patients with cholesteatoma to prevent further complications. Finally, it suggests that the tubal angle of the Eustachian may be a useful predictor of the development of cholesteatoma.

Conclusion

In conclusion, this study revealed a significant difference in the corner of the Eustachian tube between CSOM patients with and without cholesteatoma. This finding provides a basis for further research and developing more effective handling strategies in dealing with this health problem. As a step forward, it is essential to continue broader studies to explore the factors that influence the function of the Eustachian tubes and their implications for CSOM.
