Treatment of congenital bilateral choanal atresia by low temperature plasma ablation and fully degradable sinus drug stent:a case report
To investigate the application of low temperature plasma ablation combined with fullly degradable sinus stent system in the treatment of congenital choanal atresia mainly menbranous atresia.A child with mem-branous bilateral choanal atresia admitted in April 2023 was analyzed.This case underwent endoscopic ablative posterior nostriplasty and placed a fully degradable drug stent in bilateral operative cavities.The case's nasal venti-lation was effectively improved after operation and the profile of postnaris was well formed.No restenosis oratre-sia was found under electronic nasopharyngoscope and the drug stent was completely degraded after 8 months fol-low-up.Low temperature plasma ablation has the advantages of reducing surgical trauma,protecting normal tis-sue and avoiding complications in the treatment of congenital choanal atresia.At the same time,combined with the application of the fully degradable sinus drug stent,it can achieve remarkable efficacy by alleviating mucosal e-dema,reducing granulation tissue hyperplasia,accelerating wound mucosification,and effectively reducing the in-cidence of nasal adhesion,restenosis or even atresia.
