Investigation and endoscopic treatment for functional and anatomical obstruction of the nasolacrimal duct system.

The purpose of this study was to assess the results of endonasal DCR in patients with a functional obstruction of the nasolacrimal system. The study design was a prospective non-randomized interventional case series. A prospective series of 102 consecutive endoscopic DCRs were evaluated with preoperative dacrycytography (DCG) and lacrimal scintillography. Evaluation of the DCG and scintillography allowed the patients to be classified as either having an anatomical or functional obstruction of the nasolacrimal system. The powered endoscopic DCR was performed between January 1999 and December 2001. Patients were followed up for a minimum of 12 months after surgery. In the 70 powered endoscopic DCRs for anatomical obstruction, 68 (97%) have remained asymptomatic with a free flow of fluorescein from the conjunctiva to the nose. In the patients who were classified as having a functional obstruction, 27 of 32 were asymptomatic (84%) with a free flow of fluorescein into the nose. To conclude, powered endoscopic DCR produces excellent results in patients with anatomical obstruction and good results in patients with functional obstruction of the nasolacrimal system.

[Comparison of anatomy and imaging of the orbital area and the nasolacrimal duct].

The orbit and its appendages were analysed on anatomical sections, CT scans and magnetic resonance imaging in order to define the various constituents of the orbitonasolacrimal apparatus in the various planes. The series of sections presented should enable surgeons to define the landmarks in this region, especially in the approach to deep structures.

Dacryocystitis associated with nasolacrimal duct cyst.

An infant presented with persistent epiphora after successful probing of the lacrimal system. Examination of the nose showed a cystic structure occluding lower portion of the lacrimal drainage system. In cases of recurrent obstruction, nasal examination and endoscopic marsupialization may help guide the clinician towards the most appropriate treatment.

[Complications following temporary occlusion of the nasolacrimal duct with tissue adhesive (Histoacryl)].

This paper presents 4 cases in which the punctum had been temporarily occluded with tissue adhesive, still showing toxic tissue reaction years later. Abscess, dacryocystitis, dacryocystitis with dacryolithiasis, dacryocellulitis and polyposis were found. In the light of these findings and the relevant literature-especially with regard to late injuries-it is not advisable to use tissue adhesive, at least not for the purpose of punctal occlusion.

[Pathological changes found in the lacrimal sac during nasolacrimal duct surgery].

In the course of 489 external dacryocystorhinostomies one found: 19 pseudotumors (granulomas and inflammatory granulations), 6 true tumors (1 papilloma, 1 congenital cyst, 1 lymphoma), 6 cases of calcium deposits and stones and 1 case of epithelial metaplasia. The author points to a great number of pseudotumors which are the effect of a long-standing process of dacryocystitis treated conservatively without effect. She thinks that the surgical treatment should be undertaken as fast as possible.

[Catheterization of the nasolacrimal duct].

A technique is described for passing a guide wire through the lacrimal duct into the nose following catheterisation of the duct. The wire is passed into the pharynx, a 7 F feeding tube is passed through the nose into the pharynx and these are then pulled out of the mouth with a Magill forceps. The tip of the feeding tube is then cut off and the guide wire introduced into a side hole of the catheter. By removing the catheter, the tip of the guide wire is pulled along and can be removed from the nose.

Migration and apparent disappearance of silicone tube following treatment of nasolacrimal duct obstruction.

PURPOSE: To describe the unusual complication of migration and apparent disappearance of silicone tubes following intubation of the lacrimal drainage system. DESIGN: Interventional case reports. METHOD: Report of two patients with an unusual tube migration process. RESULTS: Silicone stents migrated nasally, with healing of the erosion tract in the wake of the migrating tube. One tube became completely internalized. CONCLUSIONS: Meticulous inspection of the medial canthal area in patients with suspected spontaneous extrusion of silicone stents from the lacrimal drainage system is warranted. Examination under anesthesia and nasal endoscopy may help locate tubes in cases of suspected nasal migration.

[Effect of tonometry and nasolacrimal duct irrigation on bacterial flora of the conjunctiva].

This study was undertaken to assess the influence of preoperative ophthalmological examinations on the microbial flora of the conjunctiva. For this purpose, 112 patients awaiting ocular surgery were included in the study. Conjunctival swabs for microbiological investigation were taken by nurses on the day of admission. In addition, specimens were taken before an ophthalmological examination, after applanation and impression tonometry, after irrigation of the lacrimal duct and 2 h after the end of all examinations. A last swab was taken preoperatively. Comparison of the microbiological results of the first two specimens only showed an agreement in 53% of the cases. The increase after tonometry and irrigation of the lacrimal duct in the number of swabs that were positive was not permanent. Swabs that were primarily germ-free and those that were mostly contaminated also showed strong bacterial fluctuation. Based on the present results, there is no strong evidence that the microorganisms found at the preoperative examinations correlate with a higher risk of postoperative infection. Disinfection of the conjunctival sac and the application of antibiotic drops are necessary on the day before the operation and immediately before it.

Granular cell tumor of the lacrimal sac and nasolacrimal duct: no invasive behavior with incomplete resection.

OBJECTIVE: Granular cell tumors are rare tumors of the periorbital region, and we present the second such case in the lacrimal sac. The natural history and clinical behavior of these tumors is reviewed. DESIGN: Case report. METHODS: The clinical presentation, workup, surgical approach, and pathology of a case of granular cell tumor of the lacrimal sac are presented. RESULTS: There has been no recurrence of the lacrimal sac tumor with incomplete resection. CONCLUSIONS: This case history further adds to the understanding of the biologic behavior of granular cell tumors in the periorbital region.

Bilateral nasolacrimal duct mucocele, a rare cause of respiratory distress: CT findings in two newborns.

Two newborns presented with severe respiratory distress caused by nasal obstruction. CT showed bilateral soft-tissue masses located under the inferior turbinates at the level of the inferior meatuses. Histologic examination showed the lesions to be compatible with nasolacrimal mucoceles. The embryology and radiographic features of this rare anomaly are discussed.
