Clinical use of acoustic rhinometry guiding radiofrequency to treat nasal obstruction / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

OBJECTIVE@#To investigate the value of acoustic rhinometry in treating patients with nasal obstruction by radiofrequency(RF).@*METHOD@#The clinical results of 46 nasal obstruction cases treated by RF were analyzed. The therapy area were determined by acoustic rhinometry.@*RESULT@#Pretherapy mean nasal cross-sectional area (NMCA) (0. 37+/-0. 16)cm(2) , the front part of inferior nasal concha minimal cross-sectional area (MCA) (1. 10+/-0. 17)cm(2) , volume of nasal cavity(NV) (5. 76 +/-2. 81) cm(3), nasal resistance(NR) (5. 96 +/- 2. 24) kPa x s/L. Post therapy NMCA(0. 68+/-0. 18)cm, MCA(1. 76+/-0. 19)cm(2), NCV (9. 10+/-2. 10)cm(3), NR(2. 42+/-0.86) kPa x s/ L. For 46 cases, there were remarkable improvements between pretherapy and post therapy ( P <0. 05). Twenty-seven cases were cured, 19 cases were improved, total effectiveness rate were 100%.@*CONCLUSION@#RF therapy guided by acoustic rhinometry may help determine the therapy area and improve the effectiveness.
