Abstract Introduction: Nasal obstruction is a frequent complaint in otorhinolaryngology outpatient clinics, and nasal valve incompetence is the cause in most cases. Scientific publications describing surgical techniques on the upper and lower lateral cartilages to improve the nasal valve are also quite frequent. Relatively few authors currently describe surgical procedures in the piriform aperture for nasal valve augmentation. We describe the surgical technique called pyriform plasty and evaluate its effectiveness subjectively through the NOSE questionnaire and objectively through the rhinomanometry evaluation. Objective: To compare pre- and post-pyriform plasty nasal airflow variations using rhinomanometry and the NOSE questionnaire. Methods: Eight patients submitted to pyriform surgery were studied. These patients were screened in the otorhinolaryngology outpatient clinic among those who complained of nasal obstruction, and who had a positive response to Cottle maneuver. They answered the NOSE questionnaire and were submitted to preoperative rhinomanometry. After 90 days, they were reassessed through the NOSE questionnaire and the postoperative rhinomanometry. The results of these two parameters were compared pre- and postoperatively. Results: Regarding the subjective measure, the NOSE questionnaire, seven patients reported improvement, of which two reported marked improvement, and one patient reported an unchanged obstructive condition. Regarding the rhinomanometry assessment, of 96 comparative measurements between the preoperative and postoperative periods, we obtained 68 measurements with an increase in nasal airflow in the postoperative period, 26 negative results, and two cases that remained unaltered between the preoperative and postoperative periods. Conclusion: When analyzing the results obtained in this study, we can conclude that the piriform plasty surgical procedure resulted in nasal airflow improvement in most of the obtained measurements.
Resumo Introdução: A obstrução nasal é queixa frequente nos ambulatórios de otorrinolaringologia, e a incompetência da válvula nasal é responsável em grande parte dos casos. São bastante frequente também as publicações de trabalhos científicos descrevendo técnicas cirúrgicas sobre as cartilagens laterais superiores e inferiores para melhorar a válvula nasal. Relativamente poucos autores descrevem atualmente procedimentos cirúrgicos na abertura piriforme para incremento da válvula nasal. Descrevemos a técnica cirúrgica chamada piriformeplastia e avaliamos a sua eficácia de forma subjetiva através do questionário NOSE e de forma objetiva através do exame rinomanometria. Objetivo: Comparar as variações do fluxo aéreo nasal pré e pós-piriformeplastia através da rinomanometria e do questionário NOSE. Método: Foram estudados 8 pacientes submetidos à piriformeplastia. Estes pacientes foram triados no ambulatório de otorrinolaringologia, pacientes estes que se queixavam de obstrução nasal, e que apresentavam resposta positiva a manobra de Cottle. Responderam ao questionário NOSE e foram submetidos a rinomanometria no pré-operatório. Após 90 dias foram reavaliados pelo questionário NOSE e pela rinomanometria pós-operatória. Os resultados desses dois parâmetros foram comparados pré e pós-operatoriamente. Resultados: Em relação a medida subjetiva, questionário NOSE, sete pacientes referiram melhora, sendo que dois deles referiram melhora acentuada, e um paciente referiu quadro obstrutivo inalterado. Em relação ao exame rinomanometria, de 96 medidas comparativas entre o pré e o pós-operatório, obtivemos 68 medidas com incremento ao fluxo aéreo nasal no pós-operatório, 26 resultados negativos, e dois casos inalterados entre pré e pós-operatório. Conclusão: O procedimento cirúrgico piriformeplastia conferiu melhoria do fluxo aéreo nasal na maioria das medidas obtidas.
