ABSTRACT
BACKGROUND@#Hasner valve incision has been recently introduced as a new treatment for ophthalmic patients with epiphora symptoms. 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, 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.

The extensive application of transnasal endoscopy for the treatment of rhino-orbital related diseases re-quires ophthalmologists to master the skill in lacrimal surgery. Unlike other ocular surgeries,endoscopic endonasal procedures needs a well understanding of the anatomical structures inside the nose as well as the skilled use of en-doscopes,which makes the training more specialized and difficult. The step-by-step mode combined with other learning methods is designed to enhance surgical skills and shorten the learning time during residency and fellowship training. It is anticipated to back up the minimally invasive and precise targeting therapy for lacrimal dis-eases.
ABSTRACT
<p><b>BACKGROUND</b>Rupture 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.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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.</p><p><b>CONCLUSIONS</b>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.</p>
