Nasal Endoscopic Assessment of Failure after External Dacryocystorhinostomy

Abstract

Nasal endoscopy is very important in diagnosing causes of failure of external DCR. Nasal endoscopy is essential before and after external DCR. DCR should be done by a team work of rhinologist and ophthalmologist. Study of mucociliary clearance of lacrimal pathway will help to improve our surgeries and whether to do small or large fenestra technique.

Evaluation of dacryocystorhinostomy failure with computed tomographic dacryocystography

“…10 Elmorsy SM et al also found that out of their 65 patients of failed external DCR 6 patients had rhinosinusitis as a cause of DCR failure. 31 The results of our study with regards to ethmoidal sinusitis as a cause of failure are in accordance with Gokcek et al and Elmorsy SM et al…”

“…28 In our study we also found bilateral concha bullosa in two patients as a cause of failure and supports the Gokcek et al, Mohd Ebrahim Yar Mohammadi et al and Elmorsy SM et al in regards to choncha bullosa being a cause of DCR failure. 10,28,31 We also found that out of the 38 patients two patients had ethmoidal sinusitis and one patient had faulty passage in ethmoid sinus. Gokcek et al also found that out of their 18 patients 3 patients had ethmoidal sinusistis which contributed to failure of DCR.…”

“…10 Elmorsy SM et al also found out of their 65 patients of failed external DCR 8 patients had choncha bullosa which contributed to cause of DCR failure. 31 Mohd Ebrahim Yar Mohammadi et al also found that out of their 50 failed DCR patients 22 (44%) patients had a concha bullosa which contributed to cause of DCR failure. 28 In our study we also found bilateral concha bullosa in two patients as a cause of failure and supports the Gokcek et al, Mohd Ebrahim Yar Mohammadi et al and Elmorsy SM et al in regards to choncha bullosa being a cause of DCR failure.…”

Evaluation of Epiphora

“…Examination of the nasal cavity and nasal endoscopy are important part of evaluation of any patient with lacrimal outfl ow pathway obstruction [ 19 ]. Anterior rhinoscopy with nasal speculum might not be able to provide a complete information about any underlying nasal pathology and an endoscopic evaluation is a must to diagnose pathologies if any.…”

External Repeat Dacryocystorhinostomy with Modified Silicone Intubation for Failed DCR: Analysis of Efficacy and Patient Tolerability

“…1,4 Development of scar tissue at the osteotomy site, seen endoscopically, is considered to be the main cause of failure. 5 Kao et al 6 have shown that the area of the osteotomy site gets reduced from 65.55 mm2 to 10.83mm2.…”
