Objective: To explore the clinical efficacy of sinus perfusion fluid for secondary treatment on rhinogenic chronic pharyngitis after endoscopic sinus surgery. Method: The sinus perfusion fluid topical decoction (Astragali Radix

Epimedii Folium leaf

Cinnamomi Ramulus

Angelicae Sinensis Radix

Carthami Flos

Magnoliae Flos

Chrysanthemi Indici Flos

Angelicae Dahuricae Radix

Gardeniae Fructus

Menthae haplocalycis Herba) were used to study its impact on the postoperative effects. The seventy-four patients were divided into treatment group (n=37) and control group (n=37)

the treatment lasted 2 months. Result: The total effective rate of treatment group was better than that of control group (89.2% vs. 72.9%

P<0.05). For nasal normalized transfer process

treatment group was faster than control group on surgical cavity clean-up time and epithelialization time (P<0.05). Conclusion: Sinus perfusion fluid topical decoction effectively improved the clinical efficacy of endoscopic sinus surgery

and was regarded as a widely used adjuvant therapy proposal for rhinogenic chronic pharyngitis after surgery.
