Why Surgeons Blamed the Tongue
Stuttering is heard in the mouth: a speaker may repeat a sound, stretch it, or struggle to begin a word. Before speech could be studied in detail, that visible difficulty made the tongue seem like a plausible source. If it appeared to seize or move incorrectly, surgeons could interpret the problem as a spasm in the organ itself—and imagine that removing part of it might stop the obstruction.
That reasoning treated speech as a mechanical action with a faulty part to cut away. But fluent speech depends on tightly timed cooperation among the brain, breathing, voice, and movements of the tongue and lips. A visible struggle at the tongue did not mean the tongue alone was causing it.
When the “Cure” Damaged Speech
Removing a wedge could not correct the coordination behind stuttering. Instead, it risked injuring an organ essential for forming sounds. Severe bleeding was one danger; lasting damage could make speaking harder or even leave a patient unable to speak. The attempt to fix a disruption in speech could therefore create a permanent physical barrier to speech.
The operation is a stark example of what happens when a complicated function is reduced to the body part where its difficulty appears. The tongue was involved in speaking, but that did not make it the source of every speech problem.
