ABSTRACT
Abstract. Relevance. Dacryolithiasis is a common disease of the lacrimal drainage system of the eye, which usually affects middle-aged women, is caused by the formation of stones (dacryoliths) in the lacrimal sac and nasolacrimal canal, and is often found during dacryocystorhinostomy. The origin of lacrimal stones is controversial. Traditionally, the development of stones in canaliculitis is associated with infection with Actinomyces spp. or the closely related genus Nocardia spp. Some evidence suggests that the entry of a foreign body into the lacrimal ducts can be a factor contributing to the formation of stones. Since dacryoliths are often an accidental finding during endoscopic endonasal dacryocystorhinostomy, this method of treatment is the main one for such pathology. Clinical case. Patient B., 19 years old, was admitted with complaints of constant lacrimation from the left eye, swelling in the area of the inner corner of the left eye, periodic purulent discharge from the left eye; these complaints had persisted for 6 months. According to CT of the lacrimal ducts with contrast, the patient was found to have obstruction of the left nasolacrimal duct at the level of the Hasner’s valve. A videoendoscopic endonasal revision of the lower nasal passage was performed, during which a foreign body (dacryolith) was found obstructing the area of the Hasner’s valve. The foreign body was removed instrumentally, and the patency of the lacrimal ducts was completely restored. Conclusion. A 19-year-old patient underwent successful surgical treatment of chronic left-sided dacryocystitis by revision of the Hasner’s valve and elimination of its obstruction by removing a foreign body.
