Efficacy of inferior turbinate coblation for treatment of nasal obstruction.
OBJECTIVE
To determine the efficacy of inferior turbinate coblation for the treatment of nasal obstruction.


METHODS
Twenty patients awaiting submucosal diathermy to the inferior turbinates were recruited into the study. All underwent inferior turbinate coblation. Pre-operative and post-operative nasal function was investigated using posterior rhinomanometry and subjective symptom scales.


RESULTS
There was no significant increase in nasal conductance two weeks after inferior turbinate coblation (p = 0.159). However, three months after inferior turbinate coblation, median nasal conductance had increased significantly, from 203 to 324 cm3/s (p = 0.004). The median increase in nasal conductance was 73 cm3/s or 43.5 per cent. Post-operative visual analogue patients' reported post-operative visual analogue scales scores for nasal obstruction decreased significantly, both two weeks (p = 0.006) and three months after inferior turbinate coblation (p = 0.001) when compared to Pre-operative values. There was no change in the reported severity of rhinorrhoea, nasal itching or sneezing. There was a significant relationship (rho = -0.57, p = 0.014) between pre-operative nasal conductance and change in nasal conductance after inferior turbinate coblation.


CONCLUSIONS
This study confirms the short-term efficacy of inferior turbinate coblation for the treatment of nasal obstruction. The benefit was greatest in patients with lower pre-operative nasal conductance. Objective measures of nasal obstruction may be important when selecting patients for inferior turbinate coblation.
