[Comparative morphological assessment of the damaging effects of cold plasma and radio wave energy on the mucous membrane of the lip in the experiment].

Unlabelled: The aim of this study was a comparative morphological assessment of changes in the mucous membrane of the lip in the field of radio wave and cold plasma exposure in the experiment.

Material And Methods: Experimental animals removed a portion of the mucous membrane of the inner surface of the lip with a Surgitron radio knife (group 1) and an electrode of the Coblator II cold plasma apparatus (observation group 2). Tissue was taken from the edge of the surgical wound as a trapezoidal flap containing mucous and submucous membranes immediately after the incision and 3 weeks after the surgery.

[Transcanalicular endoscopy of the lacrimal pathways].

Purpose: To study the clinical significance of the method of transcanalicular dacryo-endoscopy, and to determine its place in the system of diagnostic and therapeutic measures for obstruction of lacrimal ducts (dacryostenosis).

Material And Methods: Transcanalicular endoscopy was performed in 44 patients aged 24 to 65 years with complaints characteristic of dacryostenosis on the equipment manufactured by 'Machida Endoscope Co., Ltd' (Japan).

[Stages of introduction of endonasal microendoscopic dacryocystorhinostomy into ophthalmological clinical practice].

Endonasal microendoscopic dacryocystorhinostomy has a number of important advantages over external dacryocystorhinostomy and needs to be introduced into routine practical work of all ophthalmological clinics having a dacryiologist on the staff. At the initial stage of mastering of the endonasal technique, cooperation between health-care professionals representing different disciplines, e.g.
