FIELD: medicine.
SUBSTANCE: invention refers to medicine, namely to ophthalmology, and can be used for surgical treatment of dacryocystitis and accompanying nasolacrimal duct obstruction. Method of forming a nasolacrimal fistula in endonasal endoscopic dacryocystorhinostomy involves excision of the mucosa on the lateral wall of the nasal cavity within the projection of the lachrymal sac – in front of the attachment point of the middle nasal concha, forming a bone window in the projection of the cut out mucosa in the frontal process of the upper jaw and in the lachrymal bone with the bifurcation of the shiver and dissection of the anterior-medial wall of the lachrymal sac of the same size as the bone window. Excision of mucous lateral wall of nasal cavity and excision of anterior-medial wall of lachrymal sac is performed by cold-plasma ablation with the help of "Coblator II" apparatus. Before excising the anterior-medial wall of the lachrymal sac transcanalicularly introduced into the sac is collargol solution 2 %, waiting for 30 seconds. Lachrymal sac is then filled with a viscoelastic. That is followed by dissecting a anterior-medial wall of the sac to the output of the viscoelastic stained collargolum into the nasal cavity. Exposure by cold-plasma ablation is carried out in ablation level 7 with EIC 8875-01 electrode in excising the mucous lateral wall of the nasal cavity and EIC 7070-01 electrode in excising the anterior-medial wall of the lachrymal sac.
EFFECT: method provides the surgical efficiency, reduced operational and postoperative complications, reduced duration of operation and postoperative rehabilitation due to formation of nasolacrimal fistula by endonasal endoscopic dacryocystorhinostomy using cold-plasma controlled ablation.
