RESUMEN
Nasal obstruction due to inferior turbinate hypertrophy is a common complaint. Radiofrequency-induced thermotherapy of the inferior turbinates (RFITT) under local anesthesia is now a widely used treatment, however reports of assessment of the long-term self-reported benefits and patient satisfaction of the treatment are scarce. This study focuses on the self-reported long-term effects of treatment and experience of RFITT. A questionnaire was sent to 441 patients who underwent RFITT in our clinic to treat symptoms of impaired nasal passage due to enlarged inferior turbinates. All patients had enlarged inferior turbinates on nasal examination. Patients were included if RFITT was done under local anaesthesia, was performed more than a year before the questionnaire was forwarded and on the indication-significant nasal obstruction because of enlarged inferior turbinates. Improvement of nasal breathing (by means of a Visual Analog Scale, VAS), changes in use of nasal spray (VAS), usage of pain medication, patient friendliness of the treatment, complaints reported after treatment, permanent effect of treatment during day and night time and willingness to recommend treatment to others were analyzed. No significant post-operative complications were observed. There was a significant reduction in use of nasal spray and the majority of patients interviewed reported long-term positive effects of RFITT during the daytime. This study shows that RFITT performed under local anesthesia is a valuable, minimally invasive, patient-friendly and well-tolerated treatment in patients with impaired nasal passage due to inferior turbinate hypertrophy.
