A total of 16 patients underwent implantation by techniques previously described.3 Two patients had concurrent septoplasty, whereas 5 had turbinate reductions. Nine patients were followed for a 6-month period. Valve collapse was diagnosed by way of physical examination, acoustic rhinomanometry (Rhinometrics; Interacoustics AS, Assens, Denmark), inspiratory nasal base view photographs, and a subjective questionnaire. The patients' mean age was 66 years. Data were obtained before surgery and at 1-month intervals after surgery.
