RESUMO
Objective To explore the therapeutic effect and significance of nasopharyngeal cystectomy by nasal endoscopy.Methods According to the digital table,100 patients with nasopharyngeal cyst were randomly divided into the control group (conventional nasopharyngeal cyst excision) and observation group (endoscopic treatment),each group 50 cases.The cyst complete resection rate,infection rate,hospitalization time,postoperative recurrence rate of 2 years of follow-up were compared between the two groups.Results The cysts complete resection rate,infection rate,hospitalized time,2-years follow-up recurrence rate of the observation group were 90％,4％,(10.0 ± 1.2)d,4％,respectively,which were better than those of the control group [70％,18 ％,(20.0 ± 4.2) d,16％] (χ2 =4.34,6.11,t =5.12,χ2 =6.55,all P ＜ 0.05).Conclusion The nasopharyngeal cystectomy by nasal endoscopy has relia-ble effect,low recurrence rate,fewer complications.
