ABSTRACT
INTRODUCTION:
The olfactory sense is of paramount importance for the adequate development of a child. Olfactory loss in children might have different origins. One of the most common is conductive, when nasal obstruction prevents odorants from reaching the olfactory epithelium. Rhinitis and turbinate enlargement have been proven to diminish the sense of smell in pediatric patients. A common treatment for resistant rhinitis in these patients is turbinate radiofrequency ablation (TRA). However, despite an increasing research effort in this field, there are no studies instrumentally assessing olfaction in children undergoing turbinate surgery to date. This study was designed with the aim of assessing changes in olfaction through validated instrumental tools in pediatric patients undergoing TRA for the first time.METHODS:
A prospective uncontrolled intervention clinical trial design was conducted. Two cohorts of children ranging 4-15 years old were consecutively selected from a third level referral Hospital and subjected to the universal sniff test (U-Sniff), alcohol sniff test (AST), and sniffin sticks threshold test (SST) before and 1, 3 and 6 months after surgery. Cohort A consisted of children solely undergoing TRA. Cohort B consisted of children on whom adenoidectomy and TRA had been performed. Additionally, a cohort of Spanish healthy controls, paired by sex and age, were asked to perform the U-Sniff.RESULTS:
A total of 81 participants with a mean age of 10.31 ± 2.56 years were included. Fifty-three patients underwent TRA exclusively and 28 were subjected to associated adenoidectomy. Despite a tendency toward improvement in the U-sniff scores, there were no statistically significant differences after surgery. However, statistically significant differences were obtained for threshold tasks measured with SST and AST, revealing differences at 1, 3 and 6 months after surgery compared to preoperative scores.CONCLUSIONS:
In summary, this research demonstrated adequate levels in the sense of smell regarding identification tasks, but decreased olfactory threshold scores in pediatric patients suffering from TE. TRA, alone or with adenoidectomy, improved smell threshold scores, but had no significant effect on identification tasks.Palavras-chave
