BACKGROUNDRupture of the medial canthal ligament can be caused by many events. It remains a challenge to rebuild the drainage system and restore the function. The aim of this study was to evaluate the clinical efficacy of medial canthoplasty combined with conjunctivodacryocystorhinostomy (CDCR) in patients with medial telecanthal deformities and lacrimal drainage system damage.

METHODSTwenty-two patients (22 eyes) treated with medial canthoplasty and CDCR during June 2012 to June 2014 were included in this retrospective study. For all patients, a self-tapping, titanium, low-profile head microscrew was drilled into the solid bone on the posterior aspect of the anterior lacrimal crest at the attachment position of the medial canthal ligament. Medpor-coated tear drainage tubes were applied. Distance of patient's lateral displacement before and after operation was recorded and compared. The complications of CDCR were described.

RESULTSBefore the surgery, distance of patient's canthal displacement was 4-6 mm. The canthal distance between two eyes of patients with surgery was 1 mm or less. Among patients with CDCR, four patients had proximal obstruction and two patients had distal obstruction. Five patients had tube malposition, for example, tube extrusion 1-3 months after surgery.

CONCLUSIONSMedial canthoplasty combined with CDCR is an effective surgical method for treatment of patients with medial telecanthal deformity and lacrimal drainage system obstruction. The study indicates that medial canthoplasty combined with CDCR surgery rebuilds normal appearance of eyelid and contour of the medial canthus and successfully repairs the function of the lacrimal drainage system.

OBJECTIVETo evaluate the effect of annular electrode lacrimal duct reconstruction in improving the safety and efficacy of nasolacrimal duct stent implantation for treatment of nasolacrimal duct obstruction.

METHODSThis randomized clinical trial was performed to compare the efficacy, success rate of intubation, time used for stent implantation, intraoperative pain, and extubation-assciated complications between nasolacrimal stent implantation with and without annular electrode lacrimal duct reconstruction.

RESULTSA total of 119 eligible patients were enrolled in this trial. The total curative rate at 6 months of follow up after extubation was 70.9% (83/117) in these patients, and was significnatly higher in pateinets with lacrimal duct reconstruction than in those without [80.6% (54/67) vs 58.0% (29/50); χ(2)=7.093, P<0.05]. The total success rate of stent implantation was 98.3% (117/119) in all the patients initially enrolled, and two patients experienced failure of stent implantation and were excluded; the success rate was signfiicantly higher in patients initially enrolled in the lacrimal duct reconstruction group (χ(2)=6.282, P<0.05). The median time required for intubation was shorter in lacrimal duct reconstruction group (12 s vs 33 s; Z=-36.722, P<0.05). The intendity of intraoperative pain was comparable between the two groups (t=0.833, P=0.405). The total rate of puncta injury was 43.6% (51/117) in these patients and similar between the two groups (χ(2)=1.459, P=0.227). The total rate of extubation difficulty was 9.4% (11/117) in all the patients, and was lower in lacrimal duct reconstruction group [4.5% (3/67) vs 16% (8/50); χ(2)=4.463, P<0.05]. Stent breakage in extubation occurred in 4.3% (11/117) of the patients with similar rates between the two groups (χ(2)=2.964, P=0.085). Spearman bivariate correlation analysis showed that the time required for intubation was inversely correlated with the treatment efficacy (r=-0.584, P<0.05) and positively with the occurrence of extubation difficulty (r=0.491, P<0.05); extubation difficulty was inversely correlated with the curative effect (r=-0.511, P<0.05).

CONCLUSIONAnnular electrode nasolacrimal duct reconstruction can increase the safety and efficacy of nasolacrimal duct stent implantation for treatment of nasolacrimal duct obstruction.

OBJECTIVES: Endonasal dacryocystorhinostomy (DCR) is a well-established treatment method in patients with nasolacrimal duct obstruction. However, there are a few reports about the overall management of failed endonasal DCR. We investigated the causes and management strategies of failed endonasal DCR. METHODS: This retrospective review included 61 patients (61 eyes) who had undergone revision surgery by the same surgeon after failed endonasal DCR between January 2008 and December 2012. The appropriate revision method was determined after analysis of the etiology of failure by the fluorescein dye disappearance test, nasal endoscopy, lacrimal irrigation, and probing. The criteria for success of the revision surgery were defined by the passage of fluid without resistance upon lacrimal irrigation and normalization of the tear meniscus height. RESULTS: The mean duration between the primary endonasal DCR and revision surgery was 15.3 months. The average follow-up period after revision surgery was 12.2 months. The most common cause of endoscopic revision surgery was membranous obstruction. Endoscopic revision surgery was performed in 48 patients, while lacrimal silicone tube intubation under endoscopy was performed in 13 patients. The most common indication for lacrimal silicone tube intubation was functional epiphora. The overall success rate of the revision surgery was 89%. CONCLUSION: The most common cause of failed endonasal DCR was membranous obstruction. When patients with failed endonasal DCR presented at the clinic, it is important to identify the cause of the failure. Revision surgery could increase the final success rate of endonasal DCR.
