Preloaded Monoka (Lacrijet) and congenital nasolacrimal duct obstruction: Initial results.

Study Objective: To study the performance of a pre-loaded Monoka stent in the management of congenital nasolacrimal duct obstruction (CNLDO).

Study Design: Non-randomized study of consecutive cases.

Materials And Methods: A preloaded classic Monoka silicone stent contained entirely inside its introducer (Lacrijet) was used to treat a consecutive series of subjects with CNLDO over an 11-month period (May 2019-March 2020).

Complex Stenoses and CT Features of the Nasolacrimal Canal in Congenital Nasolacrimal Duct Obstruction.

Purpose: To study the CT appearance of the nasolacrimal canal (NLC) in cases of congenital nasolacrimal duct obstruction (CNLDO) where there is a tactile sensation of a hard contact (HC) stop in the duct preventing stent intubation.

Methods: The authors retrospectively reviewed all consecutive cases of chronic CNLDO observed between 2003 and 2018 in which an apparent HC obstruction prevented nasolacrimal intubation. CT scans were reviewed to determine the cause of probing failure: distal stenosis, loss of parallelism of the NLC walls, abnormal angulations or an adjacent obstacle blocking tear outflow.

Pushed monocanalicular intubation. Pitfalls, deleterious side effects, and complications.

Purpose: To present our experience with pushed monocanalicular nasolacrimal intubation in the management of 90 consecutive cases of nasolacrimal outflow obstruction.

Materials And Method: This paper reports a non-randomized study of 90 consecutive cases treated with a pushed Monoka intubation system (Masterka™). A metal guide is placed inside a silicone tube rather than being attached at the distal end of the tube, as done with traditional pulled intubations.

Pushed monocanalicular intubation: a preliminary report.

Objective: To study the behavior of a "pushed" monocanalicular stent by means of nasal endoscopy.

Patients And Methods: Four children (six affected sides) with congenital nasolacrimal duct obstruction were treated with monocanalicular intubation with an anchoring plug. The children's mean age at the time of the operation was 33 months (range, 30-37 months).

Complications of standardized endonasal dacryocystorhinostomy with unciformectomy.

Purpose: To report the nature and frequency of complications occurring with endonasal dacryocystorhinostomy (DCR) based on routine unciformectomy.

Design: Prospective, noncomparative interventional consecutive case series study.

Participants: Endonasal DCR was performed on 300 patients with complete nasolacrimal stenosis.
