A 31-year-old man with epiphora and mucous discharge from a traumatic lacrimal fistula underwent a computed tomographic dacryocystogram, revealing a fistula extending from the anterior ethmoid air cells through the lacrimal sac to the overlying skin with coexisting nasolacrimal duct obstruction. Endoscopic dacryocystorhinostomy enabled complete marsupialization of the lacrimal sac and agger nas...

BACKGROUND Dacryocystorhinotomy (DCR) is a common procedure used to treat nasolacrimal duct obstruction. The modern external DCR, in which the lacrimal sac is opened directly into the nasal cavity, was first described in 1904 by Toti. Since that time, DCR techniques have evolved, including a transnasal endoscopic approach that has gained popularity in parallel with the growth of endoscopic sinu...

Lacrimal scintigraphy (LS) was performed on asymptomatic lacrimal drainage systems and the results were evaluated to understand the physiology of lacrimal drainage. It was found that a physiological obstruction can exist at the level of the nasolacrimal duct in normal asymptomatic individuals, and it is suggested that this obstruction is due to the resistance offered by the valve of Hasner, whi...

OBJECTIVE To determine whether there is a relationship between congenital nasolacrimal duct obstruction (CNLDO) and subsequent refractive error disorders in children. METHODS The medical records of children 5 years and younger diagnosed as having CNLDO between January 1, 2000, and December 31, 2007, were retrospectively reviewed. RESULTS Three hundred five consecutive children were diagnose...

A review of endoscopic dacryocystorhinostomy (EDCR) performed in University Hospital from 1998 till early 2001 were carried out. They were reviewed for indication, functional results, complications and other associated factors. Eleven patients (6 female and 5 male) were reviewed. All had unilateral nasolacrimal duct (NLD) obstruction (6 right, 5 left). Their ages range from 6 to 73 years. All 1...

IMPORTANCE Epiphora is a symptom resulting from obstruction of the nasolacrimal system. Classically, dacryocystorhinostomy has been performed to relieve epiphora. However, this does not address distal obstruction. Inferior meatus (IM) surgery at or near Hasner's valve has been shown to have a 92.8% short-term success rate in treating distal nasolacrimal duct (NLD) obstruction. In addition, IM s...
