Purpose Few studies have focused on the intranasal localization of the lacrimal sac during endoscopic dacryocystorhinostomy: landmarks in order to find the medial wall of the lacrimal sac have been described, but there is a lack of description of methods for the verification of the complete marsupialization of the lacrimal sac during surgery. In this report, we propose an easy and effective method for certain intraoperative identification of lacrimal sac. Methods A method in order to verify the effective marsupialization of the lacrimal sac is applied and described: to ensure that the opening of the sac in the nasal cavity is complete, the surgeon should identify the Rosenmuller valve, which is the end of the common canaliculus in the lacrimal sac. Continuous irrigation with saline solution through the inferior canaliculus can be useful to obtain a clean surgical area and to permit easy intraoperative identification of the valve. Results Between 2007 and 2015, 193 endoscopic dacryocystorhinostomies were performed in our institutions. Postoperative surgical success at last follow-up (minimum 12 months) was 93.8% (181 out of 193 of cases). No major complications were observed. Conclusions Correct and complete exposure of the lacrimal sac during surgery is crucial for a good outcome: when the opening of the common canaliculus is identified, the surgeon is assured that the sac has been correctly and completely marsupialized inside the nasal cavity.

Common Canalicular Obstruction

AbstractWe report the case of a 40-year-old woman who developed left common canalicular obstruction following insertion of a lacrimal plug. The patient underwent endoscopic dacryocystorhinostomy, revealing the presence of the lacrimal plug occluding the common canaliculus. The patient experienced symptomatic improvement of her epiphora post-operatively.

Lacrimal Drainage

The aim of this work is to study the etiological factors of failures after endonasal endoscopic dacryocystorhinostomy (EEDCR). We retrospectively studied the case reports of 485 patients (521 cases) with a relapse after EEDCR performed for primary dacryocystitis. The obtained data allowed us to reveal that the largest number of cases of relapse after EEDCR was a consequence of partial or complete obliteration of dacryocystorhinostomy (DCR) ostium (278 cases), which amounted to 53.3% of all analyzed cases. In 127 cases, the reason of recurrence after EEDCR was stenosis or obliteration of the common canaliculus ostium (24.4%). In 116 cases (22.3%), relapse after EEDCR was caused by a combination of several etiological factors. Of these, in 86 cases, synechiae and granulation in the area of dacryostomy were revealed. The retrospective analysis carried out within the framework of this work, based on the study of the results of the applied diagnostic methods, including multislice computed tomography with contrast enhancement of lacrimal drainage system, made it possible to determine and systematize the etiological factors of the development of repeated obstruction of the lacrimal drainage system after EEDCR. Key words: relapse, dacryocystitis, DCR, common canaliculus ostium, DCR ostium, synechiae.

Abstract Purpose: To investigate the therapeutic effectiveness and safety of endoscopic dacryocystorhinostomy (EN-DCR) to treat congenital nasolacrimal canal dysplasia (CNCD). Methods: Forty children (50 eyes) with congenital nasolacrimal duct obstruction (CNLDO) and lacrimal bony dysplasia, including 8 with bony atresia (10 eyes) and 32 with bony stenosis (40 eyes), were recruited in this retrospective study. Standardized EN-DCR was performed in all cases. The post-operative observations included relief of symptoms, fluorescein dye disappearance test (FDDT), syringing of lacrimal passages and anastomotic patency under nasal endoscopy. Patients were followed up for 8-18 months. Results: The standardized EN-DCR surgery had a success (cure and improvement) rate of 100%, including a cure rate of 82% and an improvement rate of 18%. The cure rate of 40 bony nasolacrimal duct stenosis was 82.5% and 10 bony nasolacrimal duct atresia was 80%. Statistical analysis showed that nether the receipt of other treatments before surgery nor the type of bony nasolacrimal duct dysplasia affected the cure rate. No significant complications were observed during the post-operative follow-up, except for four cases (4 eyes) that suffered middle turbinate and nasal mucosal adhesion and two cases with sinusitis. Conclusions: CNCD is a type of CNLDO that does not respond to conservative and conventional treatment. EN-DCR provides a safe and effective treatment for children with CNCD. It has a high success rate with a low incidence of complications.

Abstract Background: Many current literatures have described that the lacrimal sac is located just anterior to the anterior attachment (axilla) of the middle turbinate. However, there was no data on the exact boundary of the sac, especially the distance related with a permanent landmark such as the middle turbinate attachment. Objective: Determine the intranasal location of the lacrimal sac related to the middle turbinate attachment in Thai fresh cadavers. Methods: The study was performed in 26 Thai fresh cadavers, donated to Khon Kaen University, Thailand between July 2006 and July 2007. The height and width of the lacrimal sac were recorded, as well as the distances from the upper, lower, anterior and posterior border of the lacrimal sac to the axilla of the middle turbinate were measured. Results: The mean height and width of 52 lacrimal sacs were 11.2 and 6.2 mm. The mean distances from the upper, lower, anterior, and posterior border of lacrimal sac to the axilla of the middle turbinate were 4.9 mm (95%CI=4.4-5.4), 5.6 mm (95%CI=5.1-6.1), 3 mm (95%CI=2.4-3.6), and 2.9 mm (95%CI=2.3-3.5), respectively. The upper border of all lacrimal sacs were located superior to the axilla of the middle turbinate (95%CI=93.1-100), and posterior border of 44 sacs (85%, 95%CI=72.5-92.0) were located posterior to the axilla. Additionally, the anterior wall did not extend anterior to the anterior attachment of the middle turbinate in 21% of the sac. Conclusion: This study revealed the more exact intranasal location of lacrimal sacs. This is useful for surgeons to perform adequate endoscopic dacryocystorhinostomy to prevent postoperative lacrimal sump syndrome.
