Dacryolith: two case reports

Dacryolith is a concretion within the nasolacrimal system. Dacryoliths may cause intermittent epiphora without inflammation, or recurrent dacryocystitis may develop. In this report, we present two patients with dacryoliths. The first patient had presented with a complaint of swelling and epiphora and had been told that she had lacrimal canal obstruction. This patient was unaware of the cause of obliteration and was asymptomatic. The second patient complained of headache, eye swelling and inflammation; dacryolithwasdiagnosedbyclinicalexaminationanddacryocystography.Dacryolithsweredetectedon the panoramic radiographs as small, rounded, radiopaque calcifications located in the inner aspect of the medialwallof the orbit. The image ofdacryoliths must be differentiated from radiographic artefacts and foreign objects, and it is important to recognize dacryoliths on panoramic radiographs and to refer the patients for medical care, if necessary.
