PURPOSE: This article describes a speech assessment protocol for patients using either obturator prostheses or speech aid prostheses for surgically acquired defects due to cancer of the maxilla and/or soft palate. METHODS: This protocol is structured according to the executive summary of "Disability in America: Toward a National Agenda For Prevention" a report formulated by the Institute of Medicine that describes four levels of disorder: (1) pathology, (2) impairment, (3) functional limitation, and (4) disability. Assessment instruments included (1) the Sentence Intelligibility Test to measure the rate and understandability of speech, (2) a speech physiology system to measure appropriate separation of the nasal/nasopharyngeal and oral compartments, (3) a 13-point interval scale to rate speech nasality, and (4) a scale to rate self-perceptions of communication effectiveness. RESULTS: The results from two patients are reported to illustrate the outcome assessment protocol.
