Comparitive study of prolene wire stents and silicon tube stents used in 150 cases of endonasal dacryocysto-rhinostomies

ABSTRACT

Closure of the rhinostomy opening is a major factor for surgical failure in endonasal dacryocystorhinostomy. Silicone tube stent improves surgical outcomes of endoscopic dacryocystorhinostomy. We used 1-0 prolene suture wire stent which is a cheaper alternative. A comparative case series analysis study with random patient allocation done in Department of ENT, Head and Neck Surgery, KVG Medical College, Sullia. Endonasal dacryocystorhinostomy [EnDCR] were done in 150 patients who were randomly allocated into 3 groups with 50 patients each. Silicon tube stents were used in group B and prolene wire stents were used in group C. No stents were used in group A and were taken as control. In our study, 90% success in syringing patency was seen in group A, 92% success in syringing patency was seen in group B and 90% success in syringing patency was seen in group C. No significant difference in success rates were recorded in patients where no stent was used when compared with those with groups with silicon or prolene stent used. 1-0 prolene suture wire is commonly available in all operation theaters and is used as a possible substitute for silicon tube stents
