Endoscopic diode laser assisted inferior dacryocystorhinostomy with mitomycin C

ABSTRACT

To assess the efficacy of using diode laser and intraoperative mitomycin C in increasing the success rate of endoscopic DCR and to minimize the bone work by constituting a surgical window in the area of ultra thin lacrimal bone. Twenty-three patients diagnosed as having nasolacrimal duct obstruction were included in this study. Endoscopic diode laser assisted DCR with minimal bone work and with the use of MMC was done for all cases .At the end of six months 18 out of 23 patients [78.2%] were relieved of their symptoms completely, 2 patients showed incomplete improvement, while 3 patients [13.1%] continued to have persistent epiphora. The success rate was 86.9%. Turbino-nasal synechia formation occurred in one case [4.4%], Turbino-septal synechia formation and granulation tissue occurred in one case [4.4%] and granulation tissue only in one case [4.4%] endoscopic diode laser assisted DCR with minimal bone work and with the use of MMC in this series compares favorably with other techniques described in the literatures. This technique has the advantages of shortening operative time, decreasing the incidence of complications and good rate of success
