Articulatory speech performance in patients with salivary gland dysfunction: A pilot study
Rhodus / Moller / Colby / Bereuter
Difficulty with speech is a common complaint of patients with xerostomia resulting from salivary gland dysfunction. The purpose of this pilot study was to assess and compare speech tasks in three patient groups with salivary gland dysfunction arising from different etiologies (primary Sjogren's syndrome, secondary Sjogren's syndrome with systemic lupus erythematosus, and irradiation therapy for head and neck cancer) and a matched control group. Diadochokinetic speech tasks were quantified clinically and videofluoroscopically. The results indicated that significantly fewer speech tasks were completed, with or without water, but the groups with salivary gland dysfunction than by the control group. Videofluoroscopy provided excellent quantitative analysis, yielding results similar to those of the clinical measurement. In a subjective self-assessment, subjects with salivary gland dysfunction reported more problems with speech than did control subjects.
