In institutions for the deaf and dumb in Berlin, Vienna, and Groningen, this operation was frequently performed. In Groningen, eighty-one deaf-mutes were operated upon, seventeen received temporary improvement. Hubert Valleroux warned of two deaths from it in 1843. Wilde defended the procedure under proper indications, citing cases where death resulted from puncturing the membrane. The treatises on diseases of the ear by Kramer, Rau, Bonnafont, Toynbee, and Von Troltsch add little to our knowledge. Closure of the Eustachian tube was once an indication for perforation but is no longer recognized as correct since catheters became available. Thickening of the membrana tympani was another old indication dismissed today. A collection of blood, pus, or mucus in the cavity of the tympanum remains a valid indication.
Schwartze revived the operation to remove accumulations that could not find an exit through the Eustachian tube. His one hundred cases showed it effective for acute disease but less so for chronic conditions. Bougies and gold tubes were used to maintain openings, though Politzer's eyelet proved beneficial only in exceptional cases. Wreden excised a portion of the malleus handle, but this operation was dangerous and abandoned. Voltolini made incisions with galvano-cautery, which could be kept open longer than those made by knife.
Gruber’s myringotomy involved forming a flap in the membrana tympani, though it proved difficult and dangerous. F.E. Weber recommended dividing the tensor tympani muscle to relieve pressure on the labyrinth from retraction of this muscle. He had operated on about fifty cases with promising results, reducing tinnitus aurium and vertigo.

Key Takeaways
- Paracentesis is indicated for removing blood, pus, or mucus from the tympanum cavity.
- Proper indications and skilled surgeons are crucial to avoid complications.
- Modern techniques have improved upon historical methods but some principles remain relevant.
Practical Tips
- Ensure proper diagnosis before considering paracentesis.
- Use modern imaging techniques for better assessment of ear conditions.
- Consult an otolaryngologist experienced in chronic ear infections.
Warnings & Risks
- Improper indications can lead to severe complications, including death.
- Maintaining a permanent opening with foreign objects is risky and rarely beneficial.
- Excision of the malleus handle has been abandoned due to high risks.
Modern Application
While historical methods like paracentesis have evolved, understanding their principles remains valuable. Modern imaging and surgical techniques offer safer alternatives for chronic ear infections but recognizing proper indications and seeking expert care is still crucial.
Frequently Asked Questions
Q: What are the critical indications for performing paracentesis?
Paracentesis should only be performed when there is a collection of blood, pus, or mucus in the tympanum cavity that cannot exit through the Eustachian tube.
Q: Why was the operation abandoned by many after its initial popularity?
The operation was often risky and resulted in complications such as severe otitis suppurativa, which could destroy hearing power. It also proved dangerous to patients' lives.
Q: What modern alternatives are available for maintaining a permanent opening in the tympanum?
Modern techniques have moved away from using foreign objects like gold tubes or eyelets due to their risks and instead focus on safer surgical methods under proper indications.
