Conclusions
Rh-bFGF nasal-sprays and drops quickly relieve postoperative symptoms and reduce L-K scores through promoting nasal epithelialization and cilia growth. In addition, the therapeutic effect of nasal-drops is better than that of nasal-sprays. Rh-bFGF nasal-sprays and drops can also improve long-term prognosis of patients with CRSwNP. Moreover, rh-bFGF nasal-drops are an effective method of administration in postoperative patients with eosinophilic CRSwNP.
