Primary Lacrimal Canaliculitis with clinically detected concretions: One-snip punctoplasty with lateral canaliculotomy vs. punctum sparing canalicular curettage.

Purpose: To compare two distinct surgical techniques in the management of chronic Primary Lacrimal Canaliculitis (PLC) with clinically detectable concretions.

Materials And Methods: Inclusion criteria: Patients presenting with symptoms consistent with the diagnosis of primary lacrimal canaliculitis (PLC) with ocular involvement were gathered. Gomori-Grocott Methenamine Silver test was used for concretion staining.

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.

Pediatric endonasal dacryocystorhinostomy and operative standardization.

Objective: The objective of this study was to confirm that the standardized endonasal dacryocystorhinostomy (DCR) technique routinely performed in adults can be used in children.

Materials And Methods: A consecutive series of children undergoing endonasal DCR between 2003 and 2017 was analysed. The surgical procedure consisted of: preoperative CT scan, anatomical localization of the ideal surgical zone, access to the nasal cavity via an optional planned enlargement, creation of a mucoperiosteal flap, osteotomy with rongeurs and equatorial resection of the medial wall of the lacrimal sac.

Insertion of a preloaded Monoka™ stent for congenital nasolacrimal obstruction: Intraoperative observations. A preliminary study.

Study Objective: To study the intraoperative deployment of a pre-loaded probe for a "pushed" monocanalicular nasolacrimal intubation.

Study Design: Non-randomized study of consecutive cases.

Materials And Methods: Description: A classical Monoka™ silicone stent with the silicone tube attached at right angles to the punctal plug is contained entirely inside an introducer connected to a piston.

Complex Bony Congenital Nasolacrimal Duct Obstruction Caused by an Adjacent Canine Tooth Bud.

The authors report the case of a 7-year old child with failed probing with stent intubation, who was found to have an unusual curvature of the nasolacrimal duct on the symptomatic side. CT imaging revealed a permanent maxillary canine tooth adjacent to the duct. It appeared that the relationship of the tooth bud to the curved nasolacrimal duct was most likely responsible for the symptoms of epiphora on this anomalous side.

Intralacrimal migration of Masterka stents.

Background: Tearing and conjunctivitis in children are commonly due to lacrimal drainage system obstruction. Congenital nasolacrimal obstruction is a common pathology treated by probing with or without silicone stent insertion, depending upon the age of the child. The silicone stent is self-retaining and placed for at least one month.

Acquired fistula of the lacrimal sac and laisser-faire approach. Description of the natural history of acquired fistulas between the lacrimal sac and the skin occurring before planned endonasal dacryocystorhinostomy (DCR) and without any treatment of the fistula.

Introduction: The formation of a fistula between the lacrimal sac and the skin is a classic outcome of resistant lacrimal sac abscesses. There is currently no consensus about treatment in such cases. The goal of this study was to describe the natural history of acquired fistulas between the lacrimal sac and the skin, occurring before planned endonasal dacryocystorhinostomy (DCR) and without any treatment of the fistula.

Endoscopic dacryocystorhinostomy: the keys to surgical success.

Purpose: To describe a surgical technique for endoscopic endonasal dacryocystorhinostomy.

Methods: A consecutive case series of adult endoscopic dacryocystorhinostomy surgery was reviewed. The specific surgical approach of uncinectomy with or without septoplasty and anterior middle turbinectomy was noted.

Pushed monocanalicular intubation: an alternative stenting system for the management of congenital nasolacrimal duct obstructions.

Purpose: To present our experience with a "pushed" monocanalicular nasolacrimal intubation device in the management of nasolacrimal duct obstruction in children.

Methods: The cases of consecutive patients with nasolacrimal duct obstruction who were treated with primary probing and intubation with the Masterka were reviewed retrospectively. The Masterka includes a metal guide placed inside a silicone tube for "pushed" intubation as opposed to material attached at the distal end of the silicone for intranasal retrieval ("pulled" intubations).

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 in children under general anesthesia with spontaneous ventilation. A preliminary report.

Purpose: We studied the possibility of placing a new type of monocanalicular nasal intubation under general anesthesia with spontaneous mask ventilation in congenital nasolacrimal duct obstruction.

Patients And Method: This was a non-randomized study of consecutive cases using a monocanalicular stent called the "pushed Monoka". The benefits of anchoring with meatus fixation are similar to the original Monoka device, but the probe guide or introducer is inside the silicone tube.

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).

[Neonatal pathologies of the lacrimal system].

Neonatal obstruction of the distal part of the lachrymal system can lead to dilatation of the lachrymal sac if associated with a canaliculus problem. Clinical presentation is a blue tumor of the internal canthus. This external expansion of the lachrymal sac communicates with a nasal expansion under the inferior nasal turbinate.

[Foreign body granuloma resulting from a lacorhinostomy tube's migration associated with actinomycosis of the lacrimal sac].

Introduction: Lacorhinostomy is a surgical procedure that establishes a permanent communication between the caruncular region and the nasal fossa using a fixed tube. The main complications involve the biotolerance of this tube.

Observation: Fifteen years after lacrimal surgery, a patient presented with repeated canthal inflammation associated with epistaxis on the same side.

Cerebrospinal fluid leakage after endonasal dacryocystorhinostomy.

An endonasal dacryocystorhinostomy (DCR) was followed by cerebrospinal fluid leakage and pneumoencephalocele in an 80-year-old female patient presenting four independent risk factors for an ethmoidal breach: severe septal deviation requiring forced reclining, a cranial insertion of the perpendicular plate of the ethmoid directly onto the cribriform plate, meningeal prolapse, and extensive osteoporosis of the skull base. The use of a Killian valve speculum to recline the nasal septum was probably the main cause of the anterior skull base fracture. The defect was repaired by a composite patch of septal cartilage, abdominal fat grafts, Surgicel, and inferior turbinate mucosa.

[Mastering endonasal dacryocystorhinostomy].

A persistent, symptomatic lacrimal duct stenosis is treated by dacryocystorhinostomy (DCR), with external (EX) or endonasal (EN) access. The basic indication is the same in all cases and either route can be used. The EX route seems better in terms of speed of surgery, learning curve and cost.

Surgical anatomy of the lacrimal fossa a prospective computed tomodensitometry scan analysis.

Purpose: To establish the accurate surgical anatomy of endonasal dacryocystorhinostomy (DCR) based on the radiological analysis of underlying bony structures.

Design: Prospective noncomparative observational case series study.

Participants: Fifty-nine patients with complete nasolacrimal stenosis underwent a computed tomodensitometry (CT) scan before endonasal DCR.
