title: Chronic aspiration and laryngeal competence.
abstract: Aspiration into the lower respiratory tract can be detrimental to life. Ten patients, suffering from neurological dysphagia with aspiration, were studied. Neurological disorders can cause inadequate glottic closure resulting in aspiration. It has not been well recognized however, that even patients who have full glottic closure are still capable of aspirating in the pre- and post-deglutition stages of swallowing. The combined techniques of videofibrolaryngoscopy and videofluoroscopy are found to be the best methods for demonstrating these abnormalities. Development of new techniques, in the prevention of aspiration, should also take into account silent, pre- and post-deglutitional aspiration.
