A COMPARISON BETWEEN SURGICAL TECHNIQUES AND RESULTS OF ENDOSCOPIC DACRYOCYSTORHINOSTOMY VERSUS EXTERNAL DACRYOCYSTORHINOSTOMY
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2018, Vol 7, Issue 38
Abstract
BACKGROUND Dacryocystorhinostomy (DCR) has been touted as the standard procedure for acquired Nasolacrimal Duct Obstruction (NLDO). It can be performed through a cutaneous incision, traditionally referred to as external DCR or via a transnasal approach under either direct visualisation or endoscopic guidance. In both approaches, the lacrimal sac mucosa is connected to the nasal mucosa above the level of the mechanical obstruction at the nasolacrimal duct. Toti’s technique of external dacryocystorhinostomy (DCR) has been the treatment of choice for epiphora due to nasolacrimal duct obstruction, since 1904. With the introduction of rigid nasal endoscopes in the 1970s and the advent of endoscopic sinus surgery using powered instruments, microdebrider intranasal endoscopic dacryocystorhinostomy has been done by many otorhinolaryngologists. MATERIALS AND METHODS This study compares the stepwise procedure and outcome of external dacryocystorhinostomy with endoscopic endonasal dacryocystorhinostomy. 50 patients who were diagnosed with nasolacrimal duct obstruction or chronic dacryocystitis were included in the study. They were randomised into two groups. Group I included 25 patients who underwent external dacryocystorhinostomy and Group II included the rest of the 25 patients who underwent endoscopic endonasal dacryocystorhinostomy. RESULTS Although, both the procedures had a success rate of above 90%, endoscopic DCR was helpful in avoiding a scar on the face and injury to the neighbouring structures like the medial palpebral ligament and the angular facial vessels. The surgical duration for endoscopic DCR was short as compared to that of the external approach. CONCLUSION Our study concludes that endoscopic DCR is as good as external DCR for the treatment of nasolacrimal duct obstruction and chronic dacryocystitis.
