A reappraisal of the salpingo-pharyngeus muscle.
Closure of the eustachian tube has been studied as a function of the salpingo-pharyngeal muscle. The muscle was dissected in ten cadavers and examined histologically. Its elastic fibres and anatomic relations especially during swallowing, together with other data, all confirm that the muscle is active at rest and relaxes during deglutition.
