What is the purpose of the Uvula? Does it assist in swallowing?
Reply: --------------------
Many physicians feel that the uvula is somewhat of a vestigial anatomic structure without highly significant function. Others feel that it has a role in speech and swallowing in that it participates in the sealing off of the nasopharynx during these activities. In the majority of humans, the sealing off of the nasopharynx is accomplished by the palate itself, with or without the presence of a uvula. The uvula is often surgically removed in treatments for snoring or sleep apnea as the uvula may be the primary source of the noise of snoring, or it may be a major component in the obstruction in obstructive sleep apnea. Extensive experience with such surgery has shown that the uvula can be safely removed without adverse effects. This does not mean that there is no potential for adverse consequence in removal of the uvula. If surgery on the uvula is felt to be indicated for heroic snoring or sleep apnea, then the benefits likely outweigh the potential risks, but surgery must be done judiciously so as not to disturb the normal function of the palate in sealing of the nasopharynx during swallowing and speech.
