RESUMEN
The aim of this study was to systematically review the alterations in smell and taste functions in individuals who underwent total laryngectomy, as well as to identify in the literature some aspects involved in the evaluation of these functions in this population. We performed a systematic review on the databases Medline, LILACS and SciELO, and this data search occurred in October/2010. The search used keywords and free terms, and retrieved 84 articles, 79 from Medline, via Pubmed, and five form LILACS and SciELO. Sixteen of these articles were selected. Most studies in this review attested decline in sensory of smell and taste functions in individuals who underwent total laryngectomy and, although there is consensus regarding the damage caused to these functions by the nasal airflow interruption, it is not yet possible to evidence details in the mechanisms and structures involved, especially regarding the modifications in the olfactory mucous.

O objetivo desse estudo foi rever de forma sistemática as alterações nas funções do olfato e do paladar em indivíduos submetidos à laringectomia total, bem como identificar na literatura os aspectos envolvidos na avaliação dessas funções nesta população. Foi realizada uma revisão sistemática a partir das bases de dados MedLine, LILACS e SciELO, tendo a busca de dados ocorrida em outubro/2010. Foram encontrados 84 artigos a partir da busca de descritores e termo livre, sendo 79 da Medline, via Pubmed, e cinco da LILACS e da SciELO. Destes, foram selecionados 16 artigos. A maioria dos estudos, nesta revisão, atestou diminuição das funções sensoriais do olfato e do paladar em indivíduos submetidos à laringectomia total e, embora haja consenso com relação aos prejuízos causados a essas funções pela interrupção do fluxo aéreo nasal, ainda não é possível evidenciar minuciosamente os mecanismos e estruturas envolvidas, principalmente no que se refere às alterações da mucosa olfatória.
