Abstract
Nasolacrimal duct obstruction in the pediatric population can be from a congenital or acquired cause. Congenital nasolacrimal duct obstruction (CNLDO) from the incomplete canalization of the valve of Hasner occurs in up to 6% of newborns. Acquired obstruction can occur from traumatic events, foreign body impaction or sinusitis. This obstruction predisposes children the pediatric acute dacryocystitis (PAD). Signs and symptoms of PAD include rapid edema and erythema over the medial canthal region of the lacrimal sac, epiphora or mucopurulent discharge, tenderness and fever.
Highlights
A growing body of evidence demonstrates that endonasal endoscopic dacryocystorhinostomy techniques provide comparable results to conventional external techniques in the adult population
Pre-operatively, 54.5% (12/22) patients were diagnosed with epiphora, 27.3% (6/22) were diagnosed with dacryocystitis and 18.2% (4/22) were diagnosed with a dacryocystocele
At most recent follow up 92% (23/25) of procedures resulted in complete resolution of epiphora
Summary
A growing body of evidence demonstrates that endonasal endoscopic dacryocystorhinostomy (eDCR) techniques provide comparable results to conventional external techniques in the adult population. The purpose of this study was to evaluate safety and outcomes of powered endoscopic DCR for the management of nasolacrimal duct obstruction in the pediatric population. Nasolacrimal duct obstruction in the pediatric population can be from a congenital or acquired cause. Congenital nasolacrimal duct obstruction (CNLDO) from the incomplete canalization of the valve of Hasner occurs in up to 6% of newborns. Acquired obstruction can occur from traumatic events, foreign body impaction or sinusitis. This obstruction predisposes children the pediatric acute dacryocystitis (PAD). Signs and symptoms of PAD include rapid edema and erythema over the medial canthal region of the lacrimal sac, epiphora or mucopurulent discharge, tenderness and fever. PAD may be associated with dacryocele in neonates and infants, and in general tends to have a more rapid and progressive course. A lacrimal abscess can develop which can lead to orbital cellulitis, orbital abscess or meningitis, which may threaten vision or life
