There was no evidence of this in the left drum-head. On the other hand, the wax may have acted to protect the right ear. The use of Politzer's method did not improve the hearing; boiler-makers' deafness cases are discussed, including one where a boiler-maker had great impairment of hearing but no prior earache or discharge. Tuning-fork tests and membrana tympani examinations revealed varying degrees of hearing loss and wax accumulation. In another case, exposure to cannonading led to tinnitus and some impairment of hearing, though the membrana tympani appeared normal.

The chapter also covers experiments on the effects of quinine on the ear, showing that it may lead to congestion in the auditory apparatus. These findings suggest a need for caution when using quinine in treating ear conditions.

Syphilis is discussed as a remote cause of disease in the internal ear. The pathology of syphilitic aural disease is not fully understood but may involve hyperemia, periostitis, gummata, and lesions of the meatus auditorius internus or nerve-trunk itself.
Key Takeaways
- Large doses of quinine can cause temporary auditory issues such as tinnitus and impaired hearing.
- Boiler-makers often suffer from significant hearing impairment due to prolonged exposure to noise in the shop.
- Syphilis is a prominent remote cause of disease in the internal ear, though its pathology remains unclear.
Practical Tips
- Use caution when administering quinine for treating ear conditions; it may exacerbate existing auditory issues.
- Wear protective earplugs or earmuffs to prevent hearing damage from loud noises like those found in boiler-making shops.
- Regularly check the health of your ears if you work in noisy environments.
Warnings & Risks
- Excessive use of quinine can lead to tinnitus and hearing loss, even without pre-existing ear conditions.
- Syphilitic aural disease may not present with pathognomonic symptoms, making diagnosis challenging.
Modern Application
While the historical context provides valuable insights into the effects of quinine on auditory health, modern medicine has developed safer alternatives for treating infections. However, understanding these risks is crucial for anyone using quinine or similar medications today.
