The Nasal Obstruction Symptom Evaluation (NOSE) scale is a reliable and valid instrument used widely in otorhinolaryngology to evaluate nasal obstruction symptoms in patients with nasal disorders. The purpose of this study was to assess nasal obstruction symptoms prospectively in patients undergoing surgically assisted rapid maxillary expansion (SARME) using the NOSE scale. Sixteen patients were studied (mean age 31±7.7 years), 10 women and six men, all with a transverse maxillary deficiency and an indication for SARME. Hyrax type devices were placed preoperatively and SARME was performed using Kraut's technique. The NOSE scale was applied prospectively to assess nasal obstruction symptoms. The results were recorded for each score on a scale ranging from 0 to 4, and these scores were multiplied by 5, generating a balanced scale from 0 to 100. Data were stratified according to NOSE scores, and nasal obstruction was categorized as mild (0-25), moderate (26-50), or severe (>50). The questionnaire was administered twice, first preoperatively and then at 6 months after surgery, and the results compared. Data were analyzed statistically using SAS statistical package software and showed that patients experienced a subjective improvement or did not have a worsening of nasal obstruction symptoms after SARME.
Este estudo avaliou prospectivamente os sintomas de obstrução nasal em pacientes submetidos à expansão rápida da maxila cirurgicamente assistida (ERMCA) usando a escala NOSE (Nasal Obstruction Symptom Evaluation). Foram estudados dezesseis pacientes (idade média 31 ± 7,7 anos), dez mulheres e seis homens, que necessitaram de ERMCA. Os pacientes receberam no pré-operatório, aparelhos do tipo Hyrax e os procedimentos de ERMCA foram executados pela técnica de Kraut (1984), sob anestesia geral. O questionário (NOSE) foi aplicado no pré-operatório e aos seis meses de pós-operatório e os resultados foram comparados. Os resultados para cada indicador foram obtidos em uma escala que variou de 0 a 4 e multiplicados por 5, gerando uma escala de 0 a 100. Os dados foram estratificados de acordo com os índices NOSE e a obstrução nasal foi categorizada como LEVE (0 a 25), MODERADA (26 a 50) e GRAVE (> 50). Os dados foram submetidos ao tratamento estatístico utilizando-se o pacote estatístico SAS ® , e o teste de Wilcoxon foi utilizado para comparação entre os grupos, com nível de significância de 5%. Todos os pacientes mantiveram ou melhoraram dos sintomas de obstrução nasal seis meses após a ERMCA, quando avaliados por meio da escala NOSE.Concluiu-se que a avaliação por meio da escala NOSE demonstrou que a ERMCA pode melhorar a sintomatologia de obstrução nasal.
