In order to provide subsidies to the analysis of the speech-language and hearing pathologist work in Primary Care, specifically in the Nucleus of Support for Family Health (NASF), this study conducted a literature review on the subject using the search tools of Medline, SciELO and LILACS, through the simultaneous advanced database search of the Virtual Health Library - Bireme. The study briefly recovered the history of Speech-Language and Hearing Pathology on the Brazilian's national health system (Unified Health System - SUS), and emphasized the importance of the Family Health Strategy related to Speech-Language and Hearing Pathology services in the NASFs. The literature review indicates that the performance of Speech-Language and Hearing Pathology within the health system is quite extensive, spanning different levels of assistance, which requires the development of different technologies of health work. Actions developed by NASFs necessarily require the performance of interdisciplinary teams, involved in interdisciplinary work processes and in the creation/invention of therapeutic strategies. The analysis of Speech-Language and Hearing Pathology's experiences in Primary Health Care, in Family Health Care and, more recently, in NASFs, deserves to be closely monitored and evaluated, so the production and systematization of health care practices can advance to attend the population needs, and can be able to face the serious effects of language, voice, oral motor and hearing disorders. Thus, it is necessary to monitor and to systematize the limits and potentials of this model, aiming its improvement and ownership as a strategy for the integration of Speech-Language and Hearing Pathology in the SUS.
