“…The only significant association found in this study was the higher success rate when the upper canaliculus was affected; this could be because the presence of functioning lower canaliculus makes the symptoms less. Although most recent studies[ 24 25 ] indicated that the rate of tear flow through either upper or lower canaliculus is similar, some reported that more outflow occurs through the lower canaliculus. [ 26 27 28 ] However, a study observed that lower canalicular involvement, present a unique problem in maintaining good wound closure because of the horizontal tension of the orbicularis muscles on the lacerated portion of the canaliculus and because of gravity, this could explain our results.…”

PURPOSE: To report the epidemiological data, clinical profile, management, and outcomes of canalicular lacerations in the pediatric age group in a tertiary eye care hospital in Saudi Arabia. METHODS: This retrospective study evaluated pediatric patients who underwent canalicular laceration repair in the last 15 years at King Khalid Eye Specialist Hospital (KKESH), Saudi Arabia. Demographics, causes of injury, type of trauma, surgical approach, and outcomes were analyzed. The success of repair was defined as the absence of epiphora after canaliculus repair with negative dye disappearance test (DDT). Success within subgroups was compared. P < 0.05 was considered statistically significant. RESULTS: The study sample was comprised of 43 patients, with a median age of 6.35 years (range, 1.77–17.96 years). Most of the patients were males (69.8%). Sharp objects were the most common cause of canalicular laceration (46.5%), being 9 (20.9 %) caused by a metallic clothing hanger. Lower canaliculus was involved in 65.1%, upper canaliculus in 32.6%, and both canaliculi in 2.3% of patients. Canaliculus repair was performed with a bicanalicular stent in 58.1 % and monocanalicular stent in 41.9 % of patients. The success rate and risk of complications using bicanalicular or monocanalicular stent did not differ (P = 0.065). Functional success was achieved in 87.5% of patients. CONCLUSION: Canalicular laceration is common in male children, mainly affecting the lower canaliculus. There was no difference in success rate between monocanalicular and bicanalicular stent. As canalicular laceration could be related to social determinants, the main causes should be highlighted in community health education initiatives.

“…Dacryoendoscopy (DEN) guided canalicular recanalization has focused mainly on common canaliculus obstructions, as it may obviate the need of DCR ). However, endocanalicular laser surgery is a rather expensive technique, and success rate is related to the length of canalicular obstruction, which is unknown preoperatively (Athanasiov et al 2009;Liarakos et al 2009;Ali & Paulsen 2020). Canaliculodacryocystorhinostomy (CDCR) is indicated when 8 mm of the lateral upper or lower canaliculi or both are patent, aiming to reconstruct rather than bypass the lacrimal drainage system (Hurwitz & Archer 1988).…”

Purpose: The aims of the review are to summarize the aethiopathogenesis, management and outcomes of different treatments of proximal lacrimal obstructions. Methods: An electronic database (PubMed, MEDLINE and Google Scholar) search of all articles written in English and non-English language with abstract translated to English on proximal lacrimal obstructions was performed. The articles were reviewed along with their relevant cross references. Data reviewed included demographics, presentations, investigations, management, complications and outcomes. Results: Punctoplasty is as effective as punctal dilatation with monocanalicular or bicanalicular stent in case of punctal stenosis. Dacryocystorhinostomy with retrograde intubation is more effective in case of proximal canalicular obstructions than in case of mid-canalicular obstructions. Trephination and intubation is effective in both mid and distal canalicular obstructions in patients with no associated nasolacrimal duct obstruction. Canaliculodacryocystorhinostomy has a specific indication in case of proximal common canalicular obstruction. Bypass surgery is the preferred treatment if there is no residual patency, however surgical success may not match patient satisfaction. Conclusion: Optimal choice of surgical method depends on identification of the site of obstruction. Mini-invasive techniques should be avoided in cases that would only benefit from standard surgical treatment.

“…Lacrimal recanalization surgery includes endoscopic-guided trephination dacryocystorhinostomy, dacryorhinotomy, microdrill dacryoplasty, laser dacryoplasty, and anterograde balloon dacryoplasty. [3][4][5][6][7][8][9][10] Silicone intubation or anterograde balloon dacryoplasty with a silicone tube intubation is commonly employed to treat a partial obstruction or stenosis of the lacrimal duct. [11][12][13] In Northeast Asia, silicone intubation has been proposed as an alternative to DCR in the treatment of post-saccal obstruction.…”

This study was designed to compare the postoperative outcomes of bicanalicular intubation using different diameters of silicone tubes to treat post-saccal nasolacrimal duct obstruction. A total of 130 patients diagnosed with post-saccal obstruction who underwent endoscopic-assisted silicone tube intubation were included in the study. The patients were divided into two groups; those intubated with a 1.5-mm large diameter tube (Group LD) and those with a 1.0-mm normal diameter tube (Group ND). The patency rates of the two groups at one year after tube removal were compared using the Kaplan–Meier's curve and Restricted mean survival time (RMST) method with τ = 365 days. Results showed that the recurrence rate after tube removal was significantly lower in the LD group compared to the ND group (p = 0.001). The patency rates at one year after removal in the LD and ND group were 0.857 (0.754-0.919) and 0.739 (0.617-0.828), respectively. When comparing the patency rates by the RMST method at τ = 365 days, the RMST difference, RMST ratio, and RMTL ratio were higher in the LD group at p = 0.045, 0.052, and 0.046, respectively.
