Compare Between Temperature-controlled and Nontemperature-controlled Radiofrequency Nose

2014-07-23 21:11:01 | BioPortfolio


Both chronic rhinitis and obstructive sleep disordered breathing (OSDB) are very common and have a relatively strong association to each other. Treatment of rhinitis will have at least some benefits on OSDB patients. Currently, there are several alternative treatments for these patients including radiofrequency (RF) inferior turbinate reduction. Although, most of the researches have been focusing on temperature-controlled RF (TCRF), the cost is a major limitation for applying it worldwide. The investigators objective of this study is to compare the effectiveness and safety of non-temperature-controlled RF (NTCRF) with the more popular TCRF. The investigators hypotheses that both have equal effectiveness and safety. However, the investigators believe that NTCRF have a lot less cost and faster to apply for OSDB patients in Thailand and other developing countries.


We will include around 100 patients, 50 for TCRF and 50 for NTCRF) and follow up for 1 year. We will compare both VAS, mucociliary test, ARM, RMM on all patients.
