The aim of this study was to examine whether surgical outcomes of Hasner valve incision for inferior nasolacrimal duct obstruction were different between pediatric and adult patients.Methods:A total of 53 eyes of 52 patients who underwent Hasner valve incision in the Beijing Tongren Hospital from October 2016 to November 2019 were retrospectively observed. Patients were divided into two groups, including pediatric group (23 eyes of 22 patients, <18 years old) and adult group (30 eyes of 30 patients, ≥18 years old). Success rate of surgery was determined by both subjective measure (complete resolution of epiphora) and objective measure (lacrimal passage irrigation and tear meniscus height). Fisher exact test was conducted.Results:By conducting Fisher exact test and comparing complete resolution of epiphora ( P = 0.627), lacrimal passage irrigation ( P = 0.663), measurement of Tear Meniscus Height ( P = 0.561), and appearance of complication ( P = 0.339), there was no statistically significant difference of surgical outcomes between pediatric and adult patients ( P > 0.05). Conclusion:Hasner valve incision was effective for both adult and children with inferior nasolacrimal duct obstruction, with no difference in surgical outcomes between the two groups.展开更多

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. Methods: Twenty-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. Results: Before 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. Conclusions: Medial 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.展开更多
