Topical Anesthesia Versus Submucosal Injection for Radiofrequency Turbinoplasty: Same Benefit but without Patient's...

This study aimed at comparing the anesthetic efficacy of lidocaine injection versus pledgets soaked in lidocaine and epinephrine during radiosurgery of inferior turbinates. The study prospectively enrolled 120 outbound patients, who were randomly assigned to group 1 -anaesthesia with tampon soaked in lidocaine and adrenaline- or group 2 -anesthesia with tampon followed by lidocaine and adrenaline injection. The following parameters were evaluated by a visual analogue scale 1 h after surgery: pain, anxiety, chocking sensation and difficulty swallowing. Nasal obstruction, rhinorrhea, sneezing, headache and inferior turbinate size were evaluated preoperatively (T0), after 1 (T1), 2 (T2) and 3 months (T3) to surgery. The data collected were analyzed by statistic tests. Group 1 showed lesser pain than group 2 during the procedure (p < 0.01); no statistically significant differences were observed for anxiety, chocking sensation and difficulty swallowing. All patients, independently from the belonging group, significantly improved the nasal symptoms comparing T0 and T1 (p < 0.01), T2 (p < 0.01) and T3 (p < 0.01), without statistically significant differences among the groups. Radiofrequency turbinoplasty allowed to all patients to reduce the turbinates hypertrophy. Local anaesthesia with tampon allowed to obtain the same results the injective anaesthesia in term of surgical outcomes; the use of tampon allowed patients did not experience pain.
