Abstract
A randomized prospective trial was conducted to compare the efficacy of laser cautery against sub-mucosal diathermy to the inferior turbinates in 29 patients with rhinitis. Laser diathermy was performed using an arthroscopic fitment to a CO2 laser. Subjective and objective measurement of airway obstruction were performed, using a linear analogue scale and a nasal peak inspiratory flow meter, before operation and at 3 days and 6 weeks afterwards. In both groups there was a similar and significant improvement in subjective scores at 6 weeks (SMD from 3.6 to 1.8, P less than 0.01; laser from 3.9 to 2.1, P less than 0.001), but only the laser group was significantly better at Day 3 (SMD from 3.6 to 3.5, n.s.; laser from 3.9 to 3.0, P less than 0.05). In addition, there was significantly more general subjective morbidity at Day 3 in the SMD group (P less than 0.01). The objective scores improved equally in both groups but were not significant. We conclude that laser cautery of the inferior turbinate is a superior alternative to SMD for the treatment of rhinitis.
