Introduction & Objective: Nasolacrimal duct obstruction (NLDO) is the most common cause of epiphora in adults. Our purpose was the evaluation of efficacy and complications of NLD probing with adjunctive MMC in the treatment of partial NLDO in adults. Materials & methods: This clinical trial study without control group (quazi experimental) was carried out in adult patients with symptom of epi...
injection of mitomycin-c in nasolacrimal duct for treatment of partial nasolacrimal duct obstruction
purpose: to determine the safety and efficacy of mitomycin-c injection into the lacrimal duct for treatment of partial nasolacrimal duct obstruction in adults. method: this is a before-after clinical trial performed on 20 patients with partial primary acquired nasolacrimal duct obstruction. we injected 1.5 ml of mitomycin-c 0.2 mg/ml into the lacrimal duct and repeated it with concentration of...
. PURPOSE Dacryocystorhinostomy (DCR) is the standard surgical treatment for adult nasolacrimal duct obstruction. There have been relatively few studies of closed nasolacrimal duct intubation in adults. The aim of this study was to determine rates of anatomic patency following this procedure. METHODS The authors carried out a survey of all patients undergoing closed nasolacrimal duct intuba...
developmental midline perinasal masses in children are rare lesions specifically in association with choristomas. we encountered a 3-year-old boy with epiphora, a striking mass on the nasal bridge and ipsilateral nasal hypoplasia. ct scan imaging showed multiple calcified areas within the tumor in addition to linear defect in frontal bone, hypoplastic left ethmoidal sinus and left nasal cavity,...
The rabbit’s anatomy of the nasolacrimal system is unique, with a single lacrimal punctum and a tortuous nasolacrimal duct. Inflammation of the nasolacrimal duct, dacryocystitis, can be caused by primary infection with bacteria from the respiratory tract, secondary to infectious conjunctivitis or nasolacrimal duct obstruction. The latter can occur due to the rabbit’s anatomy features, the tears...
purpose : rhinoplasty is one of the most common cosmetic surgeries. lateral osteotomy is one of the surgical steps used in rhinoplasty. there are several procedures to determine the tear passage time through nasolacrimal duct (nld) such as dacryocystography, dacryoscintigraphy, taste test, etc. one of the useful tests which can be used for determination of tear passage through nld is dripping o...
AIM To report the outcomes of endoscopic guided anterograde 3 mm balloon dacryoplasty with silicone intubation in patients with acquired partial nasolacrimal duct obstructions in adults. METHODS Retrospective case series, included 21 eyes with partially obstructed nasolacrimal ducts of 12 patients. All the 21 ducts were initially probed and the probe confirmed with an endoscope in the inferio...
Background: To report the clinical experience and analysis of our results with Ritleng intubation system in patients with congenital and acquired nasolacrimal duct obstruction. Methods: Silicone intubation with the Ritleng lacrimal system was performed in 17 patients (20 eyes) from March 2001 to March 2003 to relieve nasolacrimal duct obstruction following the failure of nasolacrimal duct probi...
External dacryocystorhinostomy (DCR) is the gold standard surgical technique for the treatment of nasolacrimal duct obstruction (1). Since its introduction by Gibbs in 1967, intubation with silicone tubes has been widely used in lacrimal duct surgery (2). However, effect of silicone intubation on patency of lacrimal system during external DCR in cases of primary nasolacrimal duct obstruction (N...
CASE DESCRIPTION An 8-year-old Hanoverian mare was presented for chronic mucopurulent discharge in the left eye, which was responsive to topical antibiotic therapy. CLINICAL FINDINGS The nasolacrimal orifice was absent in the left nasal meatum, and anterograde irrigation of left nasolacrimal duct was not possible. Dacryocystorhinography was performed and revealed about 4-6 cm of distal nasola...
