FIELD: medicine.SUBSTANCE: invention refers to medicine, namely to ophthalmology and otorhinolaryngology, and aims at surgical management of chronic dacryocystitis. An endoscopic examination covers the inferior concha, and a nasal canal is inspected from a transmaxillary approach to determine an involvement level: at the level of a distal portion and a valve of Hasner, at the level of a middle one-third of the nasal canal, and at the level of a proximal portion and a bed of the lachrymal sac. The involved levels are decompressed by a resection of narrowed or injured tissues and/or bone walls. The surgical effectiveness is endoscopically controlled with an intra-operative irrigation of the lachrymal passages from the maxillary sinus and under the inferior concha.EFFECT: method provides the minimally invasive manipulations with reducing a recurrence rate of dacryocystitis and its postoperative complications, ensuring higher therapeutic effectiveness by using a differentiated approach to choosing a surgical technique depending on a causation of the disease and the height of the lachrymal passages obstruction.6 cl, 8 dwg |
