Electrical activity of the masseter during swallowing after total laryngectomy.

ABSTRACT:

Unlabelled

Total laryngectomy is a surgical procedure that can change swallowing biomechanics, including muscle activity of the masseter; this muscle stabilizes the mandible.

Aim

To characterize the electrical activity of the masseter muscle during swallowing after total laryngectomy. Series study.

Material and methods

An electromyographic evaluation of swallowing was carried out; three different volumes of water (14.5 ml, 20 ml and 100 ml) were swallowed, and there was a rest condition. The electromyographic signal was normalized by Maximum Resisted Voluntary Activity - considered as 100% of electrical activity of muscles. All other values were calculated as a percentage of this parameter.

Results

There is moderate electrical activity of the masseter during sw
