Abstract
Purpose: to identify the prevalence and factors associated to olfaction disorders and describe the quality of life after total laryngectomy.
Methods: cross-sectional study to evaluate the olfactory acuity and quality of life of total laryngectomized patients in the Instituto Nacional de Cancer through the application of The University of Pennsylvania Smell Identification Test, The University of Washington Quality of Life Questionnaire and the Olfactory Acuity Pre-Rehabilitation of Smell Questionnaire.
Results: 48 total laryngectomized were evaluated, 39 males and 9 females, mean age of 62 years and mean time of 5,6 years after total laryngectomy. In the smell identification test the mean score was 17,9. According to the classification of smell in the test, most participants had some degree of olfaction disorders, only 2 subjects had their smell considered normal. In the The University of Washington Quality of Life Questionnaire, the composite score was 80.47. The domains that had the lowest scores were taste, saliva and speech. In the Olfactory Acuity Pre-Rehabilitation of Smell Questionnaire, most participants considered their smell bad to reasonable. 21 individuals reported having some degree of difficulty in daily life activities related to olfaction disorders.
Conclusion: the total laringectomized patients showed high prevalence of olfaction disorders, with impairments in their daily life activities.

Resumo
Objetivo: identificar a prevalência e os fatores associados às alterações do olfato e descrever a qualidade de vida após a laringectomia total.
Métodos: estudo transversal para avaliar a acuidade olfatória e a qualidade de vida de laringectomizados totais no Instituto Nacional de Câncer por meio da aplicação do Teste de Identificação do Olfato da Universidade da Pensilvânia, do Questionário de Qualidade de Vida da Universidade de Washington e do Questionário sobre a Acuidade Olfatória Pré-Reabilitação do Olfato.
Resultados: foram avaliados 48 laringectomizados totais, sendo 39 do sexo masculino e 9 do sexo feminino, com idade média de 62 anos e tempo médio de 5,6 anos desde a laringectomia total. No Teste de Identificação do Olfato a pontuação média foi de 17,9. De acordo com a classificação do olfato no teste, a maioria dos participantes apresentou algum grau de alteração, sendo que apenas 2 indivíduos tiveram o olfato considerado dentro da normalidade. No Questionário de Qualidade de vida da Universidade de Washington, o escore composto foi 80,47. Os domínios que apresentaram as médias de pontos mais baixas foram paladar, saliva e fala. No questionário sobre a acuidade olfatória pré-reabilitação do olfato, a maioria dos participantes consideraram seu olfato de ruim a razoável. 21 indivíduos relataram apresentar algum grau de dificuldade em suas atividades de vida diária em decorrência de alterações do olfato.
Conclusão: os laringectomizados totais apresentaram alta prevalência de alterações do olfato, com comprometimentos relacionados às suas atividades de vida diária.
