Abstract

PURPOSE: To present the morphological and chemical analysis of dacryoliths and review factors contributing to form dacryoliths with previous studies.
METHODS
From a 58-year-old female patient operated with dacryocystorhinostomy, dacryoliths were obtained during the procedure and postoperative follow-up period. Morphological and microbial analysis of the dacryoliths was performed by culture and light microscopic examination. Various electrolytes in the dacryoliths were analyzed by flame atomic absorbable spectrometry(FAAS) for Na+ and K+ and by inductively coupled plasma atomic emission spectrometry(ICPAES) for Ca2+ and Mg2+.
RESULTS
No bacterial and fungal organisms were cultured, but multiple bacterial colonies were found by H&E stain. Chemical analysis revealed mainly organic composition 97.91% and inorganic composition 2.09%. Inorganic composition was consisted with Ca2+ 0.82%, Na+ 0.76%, Mg2+ 0.27%, and K+ 0.24% in order.
CONCLUSIONS
To prevent the recurrence of the nasolacrimal duct obstruction by the dacryoliths after dacryocystorhinostomy, pathogenesis of the dacryoliths formation may be studied with morphological and chemical analysis of the Dacryoliths.
