“…Although several international studies have described aspects of the assessment and rehabilitation of olfaction in total laryngectomized patients, for decades 9,29,36 , few Brazilian studies have been giving attention to this theme 27,37 . It is necessary to assess and rehabilitate such function, since its alteration causes negative impacts on quality of life, nourishment and even on the patients' safety.…”

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.

Objective: To evaluate the characteristics of post-laryngectomy patients, including nasal endoscopy findings, that affect subjective smell improvement in the post-surgical period.Methods: Thirty patients who had undergone total laryngectomy participated in at least three sessions of a smell rehabilitation programme involving the nasal airflow-inducing manoeuvre, under the supervision of a speechlanguage pathologist. Patient characteristics and nasal endoscopy findings were evaluated.Results: Participants experienced a mean improvement in sense of smell of 61 per cent ( p < 0.001) and a significant improvement in appetite ( p = 0.002). Male patients and patients with a nasal discharge had a significantly better outcome.Conclusion: The nasal airflow-inducing manoeuvre is an effective method for improving smell perception and appetite in laryngectomy patients. There was no relationship between nasal endoscopy findings and outcome of the nasal airflow-inducing manoeuvre rehabilitation programme in our case series.

To examine the olfactory function in patients with laryngectomy and to assess the results of the Nasal Airflow-Inducing Maneuver (NAIM) odorrehabilitation technique. Design: A prospective intervention study. Setting: University hospital. Patients: Twenty-four patients, 21 men and 3 women, mean age 68 years, who underwent laryngectomy at least 5 months prior to intervention. Intervention: Speech therapists trained patients in the NAIM technique: simultaneous lowering of the jaw, floor of the mouth, tongue, base of the tongue, and soft palate while the lips are closed. Three interventions were given within 6 weeks. Main Outcome Measure: Olfactory testing with semistructured interview, the Questionnaire on Olfaction, Taste, and Appetite (QOTA), and the Scandinavian Odor-Identification Test (SOIT). Quality of life was measured with European Organization for Research and Treatment of Cancer QLQ-C30 and QLQ-H&N35 questionnaires. The patients were categorized as smellers or nonsmellers based on the SOIT results. Results: Before the treatment, 10 patients (42%) were smellers (ie, 6 had normosmia and 4 hyposmia), while 14 patients (58%) were nonsmellers (ie, all had anosmia). Thus, 18 patients had impaired olfaction. Using the NAIM technique, 13 (72%) of 18 patients with impaired olfaction showed improvement. Of the 14 nonsmellers, 7 converted to smellers after only 1 intervention session, giving us a success rate of 50% in anosmic patients after 1 session. Conclusions: Olfactory impairment is common in patients who underwent laryngectomy. The NAIM method is easy to learn and rapidly improves smell and taste. A single intervention session is sometimes sufficient, but many patients benefit from repeated training. The SOIT test is an effective and simple test for the assessment of olfaction acuity after laryngectomy.
