In patients with a history of acute paralytic poliomyelitis (APP), late progressive muscle weakness may arise, known as the progressive postpoliomyelitis muscular atrophy (PPMA). In 43 patients with PPMA, 8 were evaluated for recent or late progressive dysphagia. The mean interval between APP and onset of swallow symptoms was 27.1 years (range 23-45); the mean age of the patients was 45.4 years (range 35-52). Initial videofluorography showed signs of slight-to-moderate oropharyngeal dysfunction in 6 patients (delayed swallow reflex, diminished peristalsis of constrictor pharyngeus muscle, diminished laryngeal elevation, retention of bolus). In 2 patients, no abnormalities were found. Seven patients were reexamined after 12-36 months (mean 18). All reported subjective progression of symptoms. Videofluorography showed minor changes in 1 patient and unaltered findings in 6. No signs of aspiration were found either clinically or by video. We conclude that patients with PPMA complaining of late dysphagia do not show a significant loss in oropharyngeal function on 1-3 years follow-up.
