Abstract
Purpose. To evaluate effectiveness of nasolacrimal duct intubation with silicone tube in congenital dacryocystitis (CD) and substantiate optimal timing of its removal. Material and Methods. 25 patients with CD were operated in the Khabarovsk branch of the S. Fyodorov Eye Microsurgery Federal State Institution in order to restoring conductivity of nasolacrimal duct of using the intubation set FCI (France). In addition to ophthalmic examination methods, all children underwent scleral examination which includes determination of acid base state (pH) of the wound exudate (secretion) from the nasal cavity. Inflammatory index was also scored which characterized the severity of standard signs of inflammation in the nasal mucosa after surgery. Results. There were no complications during the surgery. Normalization of nasal exudate pH values in children with uncomplicated СD was registered by the 4th week after the surgery. Normalization of nasal exudate pH values in children with recurrent СD was registered by the 6th week, coinciding with full disappearance clinical signs of inflammation. At the indicated periods, the silastic tubes were removed. One child had relapse of disease after suffering acute rhinitis 6 months after the surgery.
