Summary

Background Because dacryoliths occur at low frequency, few studies have focused on their composition.

The investigators aimed to present findings from morphological, chemical, and mineralogic analysis of 86 dacryoliths.

Methods The team studied 86 dacryoliths obtained during 832 dacryocystorhinostomies (DCR) performed for postsaccal obstruction. The samples were analyzed with atomic infrared spectrometry (80 samples), amino acid analysis (17 samples), scanning electron microscopy, and an electron microprobe with an energy dispersive detector (7 samples).
