Myotonic dystrophy revealed at videoradiography of deglutition and speech in adult patients with velopharyngeal insufficiency: presentation of four cases.
Patients with velopharyngeal insufficiency (VPI) without cleft palate, who appear for the first time in adulthood for treatment, will probably reveal a high percentage of undiagnosed myotonic dystrophy (MD). Videoradiography of deglutition and speech reveals the diagnosis. Eleven adult noncleft palate patients with VPI were studied with videoradiography of the pharynx and esophagus. Three exhibited functional radiographic manifestations of MD during deglutition and speech. The diagnosis confirmed by neurologic examination was not known or suspected prior to videoradiography. An additional patient with VPI and suspected MD displayed the same constellation of radiographic findings. Follow-up examinations confirmed the diagnosis of MD. Three of the four patients had had symptoms of VPI since childhood, but none had complaints of deglutition problems except for accidental nasal regurgitations.
