Impacts of Recurrent Tonsillitis on the Outcome of Powered Intracapsular Tonsillectomy in Children

ABSTRACT

Background and Objectives@#To investigate the effects of recurrent tonsillitis on postoperative outcomes after powered intracapsular tonsillectomy and adenoidectomy (PITA) in children with obstructive sleep-disordered breathing (oSDB). @*Materials and Methods@#Children who underwent PITA in Kyung Hee University Hospital at Gangdong from 2016 to 2018 were classified into two oSDB groups according to comorbid chronic/recurrent acute tonsillitis (CHT). To evaluate the efficacy of the PITA technique, quality of life (QoL) was measured using the obstructive sleep apnea questionnaire (OSA-18) for 3 months after surgery. To evaluate the disadvantages of the PITA technique, we followed complications such as throat pain, otalgia, nausea, vomiting, and postoperative bleeding for 1 week after surgery. Finally, we compared the pre- and postoperative QoL and analyzed the incidence of postoperative complications in the oSDB with CHT (SDBwCHT) and oSDB without CHT (SDBsCHT) groups. @*Results@#Of the 802 enrolled patients, 135 were classified as SDBwCHT and 667 as SDBsCHT. Both groups exhibited marked improvements in QoL after PITA. The SDBwCHT group showed a change of OSA-18 score from 70.7±17.0 to 31.2±11.4. The SDBsCHT group showed a change of OSA-18 score from 70.0±17.1 to 31.0±9.9. The groups did not demonstrate statistical differences in complication rates and severity of symptoms during the first postoperative week. @*Conclusion@#Although comorbid CHT delayed improvement in postoperative symptoms, PITA is a useful technique to treat children with oSDB, regardless of CHT.
