I’m sure those of you who have been following my series discussing the features of vocal fold polyps and cysts have been itching for me to get to my final point . You’re asking, What does this mean for my voice? If I get a vocal fold polyp or cyst, what is the prognosis for returning to full, normal function? What about singing? The answer to these questions is based on the information I’ve discussed in my previous posts. So, let’s break down some of the considerations.
First, the bottom line in terms of voice recovery is going to be determined by how close to normal the shape and flexibility of your vocal folds are after treatment for your vocal fold lesion. The characteristics of the lesion will influence this recovery.
Size
Vocal fold lesions distort the vibrating cover of the vocal fold. The larger the lesion, the more distortion there will be. This may come in the form of stretching of the cover or hardening of portions of the vocal fold cover, for example. In this sense, the larger the lesion, the greater the possibility of residual scarring. Generally, larger lesions are considered less likely to resolve with voice therapy alone. Therefore, surgery is more likely to be recommended.
Shape
I’ve mentioned that some vocal fold lesions are broad-based, while others are pinched together at the base or are connected to the vocal fold with a stalk. These shape characteristics influence the treatment that will be recommended. With broad-based polyps (that are smaller in size), voice therapy may be recommended before surgery is considered. Polyps that are pinched at the base or on a stalk are often recommended for surgical removal as they are unlikely to be able to be resolved with therapy alone.
Depth
Vocal fold lesions may be found at the outer vibrating edge of the vocal fold, or they may be embedded in the vibrating cover of the vocal fold. Polyps are more likely to be found at the surface, while cysts may form either in the outer edge of the vocal fold or embedded into the vibrating cover. When a cyst is located at the outside of the vocal fold, it is more easy to remove without permanent voice damage.
Sometimes, a cyst is located deep in the tissue of the vocal fold. This is much more challenging for the surgeon to treat, as removal of the cyst may leave a gap in the vibrating tissue of the vocal fold. When there is a gap, then the vocal fold cover will not vibrate well and voice after the surgery may be poor. There may be similar concerns in removing a polyp if the contents of the polyp are pushing in toward the deeper layers of the vocal fold cover.
Encapsulation
In a previous post, I discussed the issue of encapsulation. Cysts are encapsulated fluid in a ballon-type structure, polyps do not have a capsule. Generally speaking, cysts will be recommended for surgical removal. There are cases where the cyst spontaneously deflates, but this is often not ideal as it sets the stage for it to sporadically reinflate. Therefore, the problem is not truly solved.
Bottom Line?
Size, shape, depth and encapsulation all impact the type and amount of damage there may be to the vocal folds. Issues regarding chronic or acute phonotrauma, as discussed in Part 3 of this series, should also be addressed however as vocal hyperfunction (muscle strain) may leave you at risk for recurrence of a voice injury.
Many patients are so eager to get rid of their vocal fold lesion, that they pressure their medical team toward immediate surgical intervention. This is not always wise. While modern surgical techniques are quite good, a risk of surgical scarring still exists. Some would say there is always some surgical scarring in the vocal fold cover, even if it is very small. If there is a reasonable chance that your vocal fold lesion can be treated with therapy alone, it is worth trying that option. What is “reasonable” will be determined by all of the factors I have discussed in this series…and more. A good voice-focused medical team will help you sort through them all.
