The examination of aural patients involves using a tuning fork to diagnose potential obstructions or lesions within the ear. The examiner alternates between two branches of the tuning fork while compressing one with a finger to determine if there is an obstruction on either side. If the sound is heard more distinctly through one branch, it suggests an issue in the middle ear of that side. Dr. Politzer's triple-armed diagnostic tube can be used for this purpose but requires careful application and may not always yield reliable results due to its complexity. The tuning fork test helps diagnose slight impairments in the Eustachian tube, often accompanied by catarrh of the tympanic cavity. In cases of perforation of the membrana tympani, the tuning fork is heard better on the affected side because it reduces the mobility of ossicula auditus and increases resonance from a larger air chamber.

Dr. August Lucse proposed an interference otoscope to examine ears by reflecting sound waves and measuring their intensity, which can indicate disease of peripheral parts of the hearing organ. The practical value of this apparatus depends on its ability to detect increased reflection from the worse ear, suggesting peripheric disease.

Von Conta recommended using a tuning fork and an elastic tube for testing hearing distance, noting that this method is valuable but does not yet provide accurate estimation of hearing loss.

The examination of the auditory canal and membrana tympani involves using aural specula, concave mirrors or reflectors, and angular forceps. These tools help dilate the canal and provide clear views for diagnosis.

Frequently Asked Questions
Q: What is the purpose of Dr. Politzer's triple-armed diagnostic tube?
Dr. Politzer's triple-armed diagnostic tube helps diagnose obstructions or lesions within the middle ear by comparing sound intensity through different branches.
Q: How does Lucse's interference otoscope work in diagnosing ear diseases?
Lucse's interference otoscope measures the reflection of sound waves to detect disease in peripheral parts of the hearing organ, indicating increased reflection from the worse ear suggests peripheric disease.
Q: What is Von Conta's method for testing hearing distance?
Von Conta recommended using a tuning fork and an elastic tube to test hearing distance, noting that this method provides valuable insights but does not yet offer accurate estimation of hearing loss.
