The Treatment of Chronic Non-Suppurative Inflammation—Concluded. Operations upon and through the membrana tympani have assumed a new importance within the past few years, in both chronic and acute aural disease. It is generally believed that more can be accomplished for chronic aural inflammation by such procedures. The reader will find an extensive history of this subject, starting with Cheselden's experiments on dogs and ending with Weber's operation on the tensor-tympani muscle. This chapter aims to provide a comprehensive overview of these operations as they have developed over time.
Johannes Riolanus in 1500 suggested that perforating the tympanic membrane might improve hearing, inspired by an accidental rupture caused by an ear-spoon. In 1722, T. Cheselden operated on dogs and described cases where a man smoked through his ears without losing hearing.
Dienert recommended perforation in 1748 for evacuating blood or pus from the tympanic cavity. Eli performed the first operation to improve hearing in 1760, though he was considered a charlatan. Dr. Peter Degravers incised the membrana tympani and observed some ossicles.
Sir Astley Cooper proposed the operation for Eustachian tube closure in 1800, reporting four cases with varying success. Karl Hiinly also performed the operation successfully on a patient with syphilitic ulcers of the pharynx. Despite initial enthusiasm, results were often poor and led to abandonment by many surgeons.

In France, Itard successfully removed mucus from a deaf-mute's ear after perforation. However, permanent suppuration could occur even with careful performance.

Key Takeaways
- Perforating the membrana tympani was initially proposed to improve hearing in chronic cases.
- Early experiments and case studies showed mixed results, with some success but also significant risks.
- The operation gained popularity briefly before being abandoned due to poor outcomes.
Practical Tips
- Consult an otolaryngologist for any persistent ear issues rather than attempting home remedies.
- Use modern diagnostic tools like the otoscope to assess ear conditions accurately.
Warnings & Risks
- Perforating the tympanic membrane can lead to permanent hearing loss or infection if not performed correctly.
- Historical methods may be dangerous and should never be attempted without professional medical guidance.
Modern Application
While historical techniques like membrana tympani perforation have largely been abandoned due to risks, understanding their development provides insight into the evolution of ear surgery. Modern otolaryngology uses safer and more effective methods for treating chronic ear conditions.
Frequently Asked Questions
Q: What was the first recorded suggestion regarding perforating the tympanic membrane?
Johannes Riolanus in Paris around 1500 suggested that perforating the tympanic membrane might improve hearing, inspired by an accidental rupture caused by an ear-spoon.
Q: Who were some of the early practitioners who experimented with this procedure?
Early practitioners included T. Cheselden in 1722, Eli in 1760, and Dr. Peter Degravers around 1788, each contributing to the understanding but also facing skepticism due to mixed results.
Q: What were some of the risks associated with early perforation procedures?
Early perforations could lead to permanent hearing loss or infection if not performed correctly. Additionally, there was a risk of permanent suppuration even when carefully performed.
