Abstract
AimTo compare a composite technique of Endoscopic Dacrocystorhinostomy with the conventional technique. MethodsA randomised prospective study was carried in the department of Otolaryngology Maulana Azad Medical College. Thirty patient selected for Endoscopic DCR were divided into two groups, one of which underwent conventional Endoscopic DCR and the other group were treated with a newer technique using cautery, cold instrumentation and laser at different steps of Endoscopic DCR. The patients were followed up for Nine months. Results/ConclusionBy using cautery, cold instrumentation and laser at different steps of Endoscopic DCR we were able to achieve a success rate of around 94% with this composite technique as compared to 83.3% in conventional Endoscopic DCR surgery.
Highlights
Epiphora or abnormal tearing occurs because of blockage in the lacrimal drainage system, which impairs normal tear channelling into the nose
Thirty patients who were planned for Dacryocystorhinostomy (DCR) procedure were divided into two group. 15 underwent surgery by conventional method described above while the other 15 underwent surgery by the composite technique described above
Most of the studies conducted of Endoscopic DCR have a recorded a success rate of around 80%7-10 which is lower than External DCR success rate of which are around 90%11-14
Summary
Epiphora or abnormal tearing occurs because of blockage in the lacrimal drainage system, which impairs normal tear channelling into the nose. The dacryocystorhinostomy operation, which involves fistulization of the lacrimal sac into the nasal cavity, may alleviate the symptoms. It was first described via an external approach by Toti in 19041. In 1989, McDonogh & Meiring[3] described the endoscopic transnasal DCR. A transcanalicular approach with the Neodymium: YAG laser has been described[6]. All these techniques have their advantages and disadvantages. We in this study have tried to use the best of each technique to come up with a composite technique for endoscopic DCR, using cautery, cold instrumentation and laser at various steps, which in our prospective would give better results with least number of complications for the patient
