Background: Congenital nasolacrimal duct obstruction (CNLDO) is one of the most prevalent orbital diseases in children and treatment of recalcitrant cases is always challenging. The purpose of this study is to identify the effectiveness of balloon dacryoplasty and stenting in persistent congenital nasolacrimal duct obstruction following previous intubation of nasolacrimal duct.

Methods: Our study was an interventional study from January 2015 to January 2018 on 16 lacrimal systems of 11 patients (5 males and 6 females) with congenital obstruction of the lacrimal duct (CNLDO) and a history of unsuccessful probing and stenting, in Farabi Hospital of Tehran (affiliated to Tehran University of Medical Sciences). Children who presented to our hospital and had previously been probed with or without intubation by another surgeon first underwent reprobing and re-intubation with a Crawford tube. Endoscopy of the nasolacrimal system was performed in suspected cases of false stent passage or in the presence of a history indicating nasal pathology. Crawford's Monoka tube was removed after two months. Balloon dacryoplasty with intubation was performed as the third surgery in cases who did not respond to probing and stenting after 3-6 months. The success after six months was evaluated using fluorescein dye disappearance test (FDDT) and also the resolution of the patients' symptoms.

Results: The age of the patients was 67±35.01 months (range: 26-121). The site of the canalicular stenosis in our patients was in the common canaliculi or within 2-3 mm from it. After 6 months, surgery was successfully performed in 13 lacrimal systems (81.25%). One patient with congenital lacrimal duct obstruction and Down syndrome and two other patients did not respond to balloon dacryoplasty and stenting and subsequently underwent dacryocystorhinostomy (DCR).

Conclusion: Balloon dacryoplasty combined with Monocrawford intubation is an effective surgical procedure that should be considered in cases of congenital nasolacrimal duct obstruction who have not responded to the probing and stenting of the lacrimal system.

Keywords: intubation, nasolacrimal duct obstruction, stenting, treatment outcomes, crawford intubation.
