Background: The eustachian tube (ET) is a connection between the nasopharynx and the middle ear behind the inferior nasal concha. It plays an important role in regulating air pressure across the tympanic membrane for proper transmission of sound. The pharyngeal opening of the tube is an important landmark for endoscopic evaluation in patients suffering from chronic otitis media and is also an important anatomical landmark for the transnasal approach to the infratemporal fossa. Hence, the study was done to locate the position of the pharyngeal opening of the ET in relation to various important anatomical landmarks. Methodology: Hundred (50 right and 50 left sides) adult (60-80 years) formalin-fixed sagittal sections of head and neck specimens were taken for the study, which was obtained during the undergraduate teaching program. The shape, size, and position of the pharyngeal opening of the ET were noted. The distance between the pharyngeal opening of the ET and various anatomical landmarks was measured with the help of the digital Vernier caliper. The mean and standard deviation of all the parameters were calculated and tabulated. Results: In the present study, a slit-like shape was the most common shape of the pharyngeal opening, present in 62 out of 100 specimens. The difference between the anteroposterior length and vertical height of the two sides showed a statistically significant difference. Conclusion: The present study will help to locate the position of the pharyngeal opening of the ET during otorhinolaryngological evaluation for performing various surgeries in the middle ear.

“…Triangular shape was more common on both right and left side. Very few authors like Bluestone [2] have worked on pharyngeal opening but have taken only vertical length [3]. According to the study done by Mohite et al, the vertical height was recorded to be 0.92cm on right side and 0.81cm on left side.…”

Auditory tube extends from the anterior wall of middle ear to the lateral wall of the nasopharynx at the level of inferior turbinate. It plays an important role in maintaining the equilibrium of air. In the patients suffering from chronic otitis media, the auditory tube plays an very important landmark for the endoscopic evaluation and for transnasal approach to the infratemporal fossa. The present study was aimed to locate the pharyngeal orifice of the auditory tube in relation to the important anatomical landmarks. The study was carried out on 50 sagittal head and neck sections of formalin fixed cadavers. The pharyngeal opening of auditory tube was looked for its shape, size and position. The anatomical landmarks with reference to the pharyngeal opening of auditory tube taken were posterior end of inferior turbinate, perpendicular distance from the clivus, from the roof of nasopharynx, from the posterior end of hard palate and from the anterior arch of atlas. The distance from these anatomical landmarks to the pharyngeal orifice of auditory tube were measured using digital vernier calipers. The mean and standard deviations of the distances were calculated and tabulated. The measured distances were slightly higher on the right than the left side. These differences were not statistically significant. The present study is useful for otorhinolaryngologists to locate the position of pharyngeal opening of auditory tube endoscopically and evaluate patients with diseases of middle ear.
