Surgical removal of a vocal fold cyst
In this case, surgical removal is recommended to restore voice function to normal. In other locations, a cyst is often only noticed as an incidental finding and only leads to problems in the event of a significant increase in size. In contrast to changes in the vocal fold epithelium, such as nodules and polyps, a vocal fold cyst is localized under the epithelium. Depending on the size of the cyst, it bulges with the epithelium. Sometimes only a slight convexity of the vocal fold is recognizable but the voice sound is clearly worse than visually (laryngoscopically) to suspect. One can only see the „tip of the iceberg“, so to speak. Voice therapy cannot change the organic findings in the case of a cyst. However, spontaneous rupture of the cyst may occur in the course of the procedure, so that the voice may temporarily improve as a result. This effect is usually only temporary, as the cyst can fill up again.
We primarily recommend surgery under general anesthesia. Since the origin of the cyst lies in deeper layers under the epithelium, its permanent removal requires opening the vocal fold and exposing and completely excising the cyst. Even with careful and correct surgery, the cyst may recur.
