摘要：
FIELD: medicine.SUBSTANCE: invention can be used to determine the indications for treatment of children with disorders of lachrymal passage. Spend multislice computed tomography (CT). As a water soluble contrast agent is selected drug, e.g. Ultravist. In three-dimensional reconstruction data CT scans determine the presence of contrast medium in all parts of the SOP and the nasal cavity, determine the state of the lacrimal sac - its shape, thickness and CT density of its walls, evaluate the width and shape of the nasolacrimal duct, the width of the distal part of the nasolacrimal duct (NSP) patency of the NRS. In the presence of the contrast agent in the nasal cavity and assess the condition of the topography of the soft tissues and bone structures adjacent to the SOP, including CT density. In identifying focal lesions in addition to its CT density estimate its contour. If the contrast agent is present in CNP, nasal cavity, then, regardless of its detection in the lacrimal sac, a timing intubation SOP lacrimal implant. If the contrast agent is absent in the NSP in the nasal cavity, then, regardless of its detection in the lacrimal sac, shown endonasal dacryocystorhinostomy (DCRS) with time intubation dakriostomy lacrimal implant. If there is a diverticulum of the lacrimal sac, which is manifested by the protrusion of its walls, and the contrast agent is present in the NSP, the nasal cavity, the excision of the diverticulum is shown in conjunction with simultaneous time intubation SOP lacrimal implant. If you change the shape and the thickened wall of the lacrimal sac, combined with the value of the CT density of the SOP and the surrounding soft tissues <50 HU, the contrast agent is present in the NSP, the nasal cavity, it is a time intubation SOP lacrimal implant with provisional anti-inflammatory therapy. If the contrast agent is not in the NSP, the nasal cavity, it shows the endonasal DCRS with intubation time dakriostomy lacrimal implant with provisional anti-infl
