Journal of Evolution of Medical and Dental Sciences 2014; Vol. 3, Issue 09, March 03; Page: 2121-2125, DOI: 10.14260/jemds/2014/2113 ABSTRACT: AIM: To focus on difficulties in endoscopic endonasal DCR, to improve the final outcome of endoscopic endonasal DCR. To elaborate the steps this will avoid recurrence. MATERIAL AND METHODS: This article presents retrospective study of 861 cases that underwent Endoscopic endonasal DCR between Oct 2004 and Nov 2011. The patients operated were in the age group from 5 years to 94 years. The cases of lacrimal abscesses were tackled by endo DCR which gave a substantial advantage over the conventional external approach by avoiding a scar. The stenting of the canalicular system was restricted to the situations where the patency of the lacrimal canaliculi was absent and the sac syringing done on operation table showed no fluid coming from the new stoma due to the blocked canaliculi or fibrosis of lacrimal sac. The stent used was silicon bicanalicular lacrimal intubation set. CONCLUSIONS: Local anaesthesia preferred over general anaesthesia as it has less bleeding and less morbidity. Endoscopic DCR avoids scar of external approach. Coexistent sinonasal disease can be tackled at same sitting. Adequate marsupialization of sac mucosa is key for avoiding recurrence. KEYWORDS: Dacryocystorhinostomy, Endoscopic DCR, Lacrimal abscess, Stenting. INTRODUCTION: Epiphora due to blockage of the lacrimal drainage system is the most common symptom of chronic dacryocystitis. Dacryocystorhinostomy is done to provide alternative lacrimal pathway into the nose. The operative procedure can be done intranasally (Endoscopic Dacryorhinostomy - Endo DCR) or extra nasally (Conventional DCR). Different techniques have been described for the Endo-DCR such as different flaps 1 , but in our study we have restricted to refashioning of the stoma with wide opening in the medial wall of the lacrimal sac. Here the surgical procedure do not interphere the sphincter action of the lower punctum which in turn establishes the post-op function of the lacrimal system and these results in the satisfactory recovery of the patient with no facial scar. Reduction in the morbidity, reduction in time taken for the surgical procedure and restoration of the physiological function are the prime features of the Endo nasal DCR. MATERIAL & METHODS: 861 cases between the age group of 5 years to 94 years with congenital or acquired NLD block visiting our hospital that underwent Endo nasal DCR were included in our study. The general check up with fitness for anaesthesia was done for every patient. The patients with systemic diseases as Diabetes Mellitus, Hypertension, and heart disease were thoroughly investigated for fitness for surgery. The patients on anticoagulants were assessed and the anticoagulant medication was stopped before surgery.
