“…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.

Nasolacrimal Duct Reconstruction With Nasal Mucoperiosteal Flap

Surgical repair of lacrimal drainage apparatus may be quite difficult in patients with maxillofacial injuries involving extensive structural damage. When the primary tear tract has become nonamendable or inaccessible, it would then be necessary to set up an alternate draining route for tear passage. Conjunctivorhinostomy with a Jones tube is an effective diversionary treatment method, and yet this procedure might be plagued with problems related to alloplastic device usage. Autologous tissue is therefore best suited for nasolacrimal conduit restoration.A superiorly based mucoperiosteal flap, 11 to 13 mm in width and 20 to 25 mm in vertical length, is mobilized from lateral nasal wall and fashioned into a tubelike conduit. This construct is then turned superior-laterally and connected to the conjunctival sac. The fistula tract thus formed has a sufficiently large caliber and is lined entirely with normal mucosal epithelium. Such a feature may exert a favorable influence upon the long-term patency of the tear passage. This approach is applied successfully in 3 consecutive patients of lacrimal system obstruction, one of whom even had experienced 2 failed attempts of Jones tube insertion beforehand. The tactics and experiences in managing these 3 cases form the basis of this report.

The extranasal method of dacryocystorhinostomy, which totally incorporates the lacrimal sac into the nasal cavity, is described, and the primary and late results of this method are presented in 57 patients with chronic epiphora caused by stenosis of the nasolacrimal duct. Immediately after the operation, the results were satisfactory in all patients. At late follow-up, with a median observation period of 5 years, 80% of the patients were completely free of epiphora and 15% had periodic epiphora, which was a considerable improvement over the preoperative condition. The described method could become a rhinologic routine procedure in patients with chronic epiphora.
