RESUMO
Objective To study the efficacy of chitosan on rehabilitation treatment after sinuses open surgery .Methods Fifty-six cases patients after sinuses open surgery were collected during June 2013 to October 2014 and divided into experimental group and control group by random sampling method, 28 cases in each group.The experimental group were smeared with chitosan on surface after cleaning by normal saline, while control group cleaned by normal saline alone.The efficacy, adhesion of nasal mucosa and time of mucosa complete epithelialization in two groups at three and six months were analysed while out-patient review.ResuIts After three and six months, the total effective rate of experimental group was significantly higher than that of control group[85.71% vs.60.71%(χ2 =4.46,P<0.05);92.86% vs.67.86%(χ2 =5.54,P<0.05)].The time of mucosa complete epithelialization in experimental group was (50.4 ±6.5)d, which was shorter than (62.3 ±7.5)d of control group (t=6.34,P<0.05).After three and six months, the nasal mucosa without adhesion in experimental group was better than that in control group (χ2 =5.60, χ2 =5.49;P<0.05). ConcIusion Chitosan can promote nasal mucosa epithelialization, reduce adhesion of nasal mucosa, improve the postoperative curative effect of chronic nasal-sinusitis.
