Usefulness of post-operative endoscopic score for optimal treatment selection in recurrent eosinophilic chronic rhinosinusitis

This study retrospectively analysed post-operative endoscopic scores to determine the optimal post-operative treatment in patients with eosinophilic chronic rhinosinusitis undergoing functional endoscopic sinus surgery.

In total, 339 adults who underwent initial bilateral functional endoscopic sinus surgery for eosinophilic chronic rhinosinusitis were enrolled. Patients were divided into group A, which required no additional post-operative treatment; group B, which required local/systemic steroids post-operatively; and group C, which further required dupilumab and/or revision surgery.

Sixty-five per cent of patients could be treated with initial functional endoscopic sinus surgery (group A). Post-operative steroids were required in 35 per cent of patients with a post-operative endoscopic score of 30 per cent (group B). Further advanced treatments with dupilumab and/or revision functional endoscopic sinus surgery were required in 10 per cent of patients with a post-operative endoscopic score of 65 per cent (group C).

The post functional endoscopic sinus surgery endoscopic score can be used as an index to determine treatment at the time of eosinophilic chronic rhinosinusitis recurrence.
