A 3-year, single-center, prospective study was undertaken to measure the effect and long-term results of using the Monarch Nasal Implant to surgically correct nasal valve dysfunction. Thirty-nine patients were implanted, with follow-up lasting 36 months for 9 of the patients. Implant effectiveness and maintenance of effectiveness were determined through acoustic rhinomanometry and a subjective patient questionnaire. Rhinomanometry studies and patient questionnaires revealed a significant initial improvement in internal nasal valve areas and patient symptoms; the improvements were maintained or had even increased at 36 months. The cosmetic changes were acceptable to the patients. The Monarch Nasal Implant provides a consistent and lasting correction of nasal valve dysfunction with minimal drawbacks when properly used.

Because the nasal valve represents the smallest segment of the respiratory tract in cross-sectional area,1even small changes in size or wall support can have a profound effect on nasal airflow and a significant impact on quality of life.2
