Objective To investigate the efficacy of endoscopic dacryocystorhinostomy(En-DCR)and suture anastomosis in treatment of chronic dacryocystitis.Method Clinical data of 79 cases(79 eyes)of chronic dacryocystitis were enrolled retrospectively and divided into suture group and seamless group.In the seamless group,the En-DCR valve was fixed with simple gelatin sponge,and in the suture group,the En-DCR valve suture was used.The total clinical effective rate,postoperative complication rate,anastomotic repair time and granulation hyperplasia of the two groups were analyzed and compared.Results There was no statistically significant difference in total effective rate between the two groups after operation(χ2 = 4.36,P = 0.137),there was no statistically significant difference in the incidence of complications(P = 0.705).The healing time of stoma mucosa epithelium in suture group was shorter than that in seamless group,the difference was statistically significant(t = 0.57,P = 0.032);The stoma granulation hyperplasia suture group was less than the seamless group,the difference was statistically significant(P = 0.037).Conclusion The combination of valve suture does not improve its clinical efficacy and safety,but can shorten the healing time of mucosal epithelium and reduce the granulation hyperplasia of stoma.

AIM:To analyze the effectiveness and safety of upper eyelid combined fascia sheath(CFS)suspension and levator muscle(LM)shortening surgery in correcting severe ptosis.METHODS:Retrospective study. A total of 80 cases(84 eyes)of severe ptosis treated in our hospital from June 2018 to June 2022 were divided into two groups based on the surgical method, including 40 cases(41 eyes)underwent CFS suspension + LM shortening surgery in CFS group, and 40 patients(43 eyes)underwent frontal muscle flap suspension surgery in frontal muscle group; the clinical total effective rate, postoperative complications, and patient satisfaction rate of both groups of patients were compared.RESULTS:At 12 mo postoperatively, the clinical effective rates of the two groups of patients were 98% and 91%, respectively(P>0.05). The incidence of complications was 26%(11/43)in the frontal muscle group and 7%(3/41)in the CFS group(P=0.024). The satisfaction rate of the frontal muscle group was 80%(32/40), while the CFS group was 98%(39/40; P=0.029).CONCLUSION:The use of CFS+LM surgery can effectively correct severe ptosis, with fewer complications and a more natural appearance.
