Nasal obstruction in children with sleep-disordered breathing

Abstract

Introduction: Nasal obstruction secondary to pathological enlargement of inferior nasal turbinates contributes to sleep-disordered breathing (SBD) in prepubertalchildren, but treatments designed to address turbinate enlargement are often not performed. The aims of these studies are: (1) to appreciate the contribution to SDB of untreated enlarged nasal turbinates in prepubertal children; and (2) to report our experience with treatment of enlarged nasal turbinates in young children with SDB. Materials and Methods: Children with enlarged nasal turbinates who underwent adenotonsillectomy (T&A) had significantly less improvement in postoperative apnoea-hypopnoea index (AHI) compared to those treated with concomitant turbinatereduction. Children in theuntr eated turbinate hyper trophy group subsequently under went radiofrequency ablation of the inferior nasal turbinates; following this procedure, AHI was no different than AHI of those without hyper trophy. Results: In an analysis of safety and effectiveness of radiofrequency treatment of the nasal turbinates, we found the procedure to be a well-tolerated component of SDB treatment. Conclusions: We conclude that radiofrequency (RF) treatment of inferior nasal turbinates is a safe and effective treatment in young prepubertal children with SDB. When indicated, it should be included in the treatment plan for prepubertal children with SDB. However, the duration of effectiveness is variable and therapy may need to be repeated if turbinate hypertrophy recurs.
