Stents

Some surgeons do not insert a stent, while others leave a stent in for several months. In our hands, the success rate of a laser DCR has been worse if we have removed the stents within 8 weeks. If we leave the stents in for longer than 3 months, the incidence of granulations around the tube is increased. In an endoscopic DCR using conventional instruments, the rhinostomy requires no stents if it is wide open.
