А case of combination of dacryocystocele with a nasolacrymal cyst in infant child

Abstract

INTRODUCTION: Dacryocystocele (hydrops of the lacrimal sac) is a rare variant of a congenital pathology caused by the obstruction of proximal and distal lacrimal ducts, followed by progressive distension of the lacrimal sac [1]. Given the accumulation of abundant contents in the lacrimal sac and nasolacrimal duct, the membrane that closes their outlet under the inferior turbinate can be stretched, and the prominence of such a membrane into the inferior nasal passage is in the form of the so-called nasolacrimal cyst [3].
 Description of the clinical case. A 1.5-month-old girl was hospitalized in the ophthalmology department of the University. Below are the history data. At the 30th week of pregnancy, the fetus had a bilateral space-occupying lesion in the area of the inner canthus of the eye. At birth, the child had a dense swelling in the region of the left lacrimal sac but without discharge. From birth, he had difficulty in nasal breathing.
 RESULTS: According to the results of multislice computed tomography of the lacrimal ducts with contrast (Ultravist), cavity formations were found under the inferior turbinate on both sides with a contrast level. At the age of two months, the child, accompanied by an otolaryngologist, underwent surgery for the removal of nasolacrimal cysts on both sides and reconstruction of the lacrimal ducts and their intubation with a silicone thread on the left. After surgical treatment, the outflow of tears and nasal breathing were restored, and no signs of dacryocystocele were detected. The silicone thread was removed after 1 month, and no tear production was observed.
 DISCUSSION: Treatment of children with dacryocystocele involves the simultaneous reconstruction of lacrimal ducts by an ophthalmologist and excision of the nasolacrimal cyst by an otolaryngologist.
 CONCLUSION: When examining a child with dacryocystocele, the possible presence of a nasolacrimal cyst should be considered. The interaction of an ophthalmologist and an otolaryngologist at all stages of the treatment and diagnostic process enables the prevention of disease complications and unnecessary surgical procedures.
