“…In this case, differential considerations for the unattached, calcific mass eroding through the lateral nasal wall and involving the nasolacrimal apparatus included internal, excessive growth of dacryolithiasis 3 ; external, metaplasia of inflammatory secretions secondary to sinusitis, 16 rhinitis, 16 or periapical tooth root abcessation 17 ; or neoplasia 18 . Foreign body 11,12,19 or previous surgery 20 resulting in calcifying, chronic inflammatory accumulations were considered unlikely. Topical instillation of epinephrine solution was not reported 15 .…”

A 12-year-old Paso Fino mare was evaluated for a chronic nasal and ocular discharge. A calcification was identified eroding through the nasal mucosa of the middle meatus. Differential considerations for this mass included dacryolith, nasal calculus, or calcified tooth root abscess. Anatomical location and case history and progression supported a dacryolith. Following removal, the calculus was submitted for mineralogic analysis. The calculus was primarily carbonate hydroxylapatite (Ca10(PO4)3(CO3)3(OH)2) with a minor NaCl halite constituent. Dacryoliths, or nasolacrimal calculi, are an uncommon occurrence in animals, and sparsely reported in humans. The etiopathogenesis of dacryolith formation is unknown. The objective of this article was to report the first case report of an equine nasolacrimal system dacryolith and its mineralogic composition.

“…3 The middle nasal duct, ethmoid sinus, and maxillary sinus have been reported as possible drainage sites for lacrimal fluid in the treatment of patients with nasolacrimal duct obstruction. 4 The most common treatment for nasolacrimal duct obstruction is dacryocystorhinostomy (DCR), [5][6][7] which drains into the middle nasal duct. There are two types of DCR: endonasal DCR, which is performed using an endoscope, and external DCR, which is performed through a skin incision under direct vision.…”

Background: Dacryocystorhinostomy (DCR) is the standard treatment for nasolacrimal duct obstruction, but it has the disadvantage of creating a raw surface, which may lead to reocclusion due to the development of postoperative granulation tissue. In this study, we developed and evaluated an ideal new surgical method, dacryocystorhinostomy-anastomosis (DCR-A), involving end-to-side anastomosis under microscopic visualization that does not result in raw surfaces. Methods: In DCR, the lateral aspect of the dacryocyst and the nasal mucosa are incised, and the mucosal valves are sutured together. In DCR-A, the occluded section of the dacryocyst or nasolacrimal duct was trimmed and anastomosed by circumferential suturing through a hole in the nasal mucosa. The success rate and the requirement for postoperative therapy were compared between 21 sides of DCR patients and 11 sides of nasal DCR-A patients. Results: DCR-A was significantly better than conventional DCR. No additional postoperative therapy was required for DCR-A. Conclusion: DCR-A improves symptoms of nasolacrimal duct obstruction to a greater extent than conventional DCR and does not require additional postoperative treatment.

“…Idiopathic or primary acquired nasolacrimal duct obstruction (NLDO)1 is a syndrome of unknown aetiology and accounts for the majority of NLDO found in adults. It is postulated that inflammation of unknown cause results in possible occlusive fibrosis2 of the nasolacrimal system (NLS) causing obstruction and subsequent epiphora3 4 or “watering eye”.…”

Aims-To determine the eYcacy of probing in the initial treatment of epiphora and the symptom free period in adults with blocked nasolacrimal ducts. Methods-The results of probing in 85 eyes with epiphora due to nasolacrimal duct obstruction were studied retrospectively after a mean follow up of 7.4 months (SD 11.6) by a questionnaire and interview survey of patients. Results-35% of the eyes had an outcome of no watering after probing, 17% mild watering, 35% moderate watering, and 11% severe watering. The patients' satisfaction (watering subjectively improved) after undergoing this procedure was 82%, which is higher than previously reported. The mean symptom free period in eyes with no watering was 11.25 months, in eyes with mild watering 8.20 months, in eyes with moderate watering 5.35 months, and in eyes with severe watering 0.95 months. There was a significant diVerence (p=0.001) in the symptom free period between the no watering and severe watering groups. Conclusions-Probing in adults with confirmed nasolacrimal duct obstruction can be recommended as an initial treatment procedure because of its relatively good eYcacy and high patient satisfaction without compromising subsequent surgical treatment if unsuccessful.
