Analysis of congenital dacryostenosis in consideration of mucoceles
Pollack K., Sommer E.
Department of Ophthalmology, Technical University Dresden, Fetscherstraße 74, D-01307 Dresden
Obstruction of the distal aspect of the nasolacrimal duct is common occuring
in 30 % of newborns. Dacryocystitis or mucoceles are rarely seen in newborns,
because of spontaneous rupture of the membrane soon after birth due to
mechanical stress. This will happen in 90 % of all cases. Persisting of
the membrane will lead to an acute dacryocystitis which can become chronical.
Congenital mucocele refers to a distended lacrimal sac present around
birth.
Patients and methods: A retrospectiv analysis congenital dacryostenosis
who where treated over a 4 years period was performed. 256 cases(130 girls,
126 boys) were included. Age ranged from few days to 31 month.
Results: Bilateral dacryostenosis was found in 20 % of cases. Congenital
mucocele occurred in 11 cases. There were a strong female preponderance(10
cases). Unilateral mucocele was found in 10 cases. Syringing and probing
was required. Repeated intervention was necessary in 10 cases. One mucocele
required probing with silicone tube placement.
Conclusions: A congenital mucocele is one differential diagnosis
possibilitiy in cases of blue swelling in the area of medial canthus at
newborns. An immediatly therapy is necessary. Syringing and probing of
nasolacrimal ducts should be realized in the first 6 months after birth,
because the treatment can be performed in local anaesthesia.
