Endonasal dacryocystocele of the newborn.

The true incidence of endonasal dacryocystocele in the newborn is probably underestimated; the number of cases in the last few years has increased with better imaging techniques and diagnostic tools. Although infrequent, it must be considered in the differential diagnosis of neonatal respiratory distress and nasal obstruction. These children typically present an endonasal mass under the inferior turbinate, most often associated with inner canthal swelling. This series of four patients represents one of the largest to be reported since the first publication on the subject by Goralowna in 1979.
