Can Sinus Surgery Change your Voice?

The sound of your voice is created by air flowing across the vocal cords. In order to make the sound of our voice, the vocal cords are brought together as we exhale, this causes very fast vibrations, giving rise to sound waves. In order to create the many different intonations and pitches of our voice, the vocal cords are constantly adjusting their movements to give our rise our own, particular voice.

Changes in the sound of our voice occur when vocal cord motions are altered. For example, if you have a cold, the sound of your voice changes due to the swelling of the vocal cords.

But it is not just the vocal cords that have a role in speech. The throat is very involved in amplifying and adjusting the sound of our voice, the tongue, palate (roof of the mouth) and throat muscles are also active in the creation of the unique sound of our own voice. When we have a cold or throat infection, the sound of our voice is altered as well, usually causing a lower pitch.

The sound of our voice is also affected by the sinus cavities in the facial bone. The sinuses are air filled spaces within the bones of the face and skull, these spaces lighten the skull so the head is less heavy. If the sinus tissue becomes inflamed due to an infection or injury. the resonance of our voice is dramatically changed and easily apparent to anyone who is familiar with your voice.

Occasionally, sinus surgery may lead to persistent swelling and thickening of the lining tissues of the sinuses, resulting in a change of resonance the sound of a person’s voice. Fortunately, the alteration of the voice usually improves over time.
