Endonasal balloon dacryoplasty in partial and complete obstruction of dacryocystorhinostomy ostium.

Unlabelled: Despite the success of dacryocystorhinostomy (DCR) in the treatment of lacrimal drainage system (LDS) obliteration and the use of medical and surgical methods to prevent its recurrence, the number of relapses reaches 37%. The main etiological factor leading to this pathology is partial (stenosis) or complete obstruction of the ostium.

Purpose: To study the effectiveness of endonasal balloon dacryoplasty in partial or complete obstruction of dacryocystorhinostomy ostium.

[Formation of concrements in the lacrimal excretory system].

Studying the pathogenesis of concrements formation in lacrimal ducts is of fundamental and practical importance. This article attempts to analyze available information related to the pathogenesis of this phenomenon, provides information on the etiopathogenesis, physical and chemical properties of concrements obtained from horizontal and vertical parts of the lacrimal duct, and considers in detail bacteriological and mycotic composition of concrements, as well as various theories of their formation. The analysis helped justify the need to separate the concrements formed in the horizontal and vertical parts of the lacrimal ducts on the basis of differences in their pathogenesis.

[Conjunctival dacryocystorhinostomy in the treatment of proximal lacrimal drainage obstruction].

The problem of reconstruction of the lacrimal drainage system in cases of obliteration of both lacrimal points and/or both lacrimal canaliculi remains one of the most difficult in dacryology. The most common and effective operation for this pathology is Conjunctival dacryocystorhinostomy using tubes developed by L. Jones in 1962.

[Transcanalicular balloon dacryoplasty for the treatment of post-dacryocystorhinostomy recurrent stenoses].

Purpose: To compare the effectiveness of minimally invasive techniques used for the treatment of common canalicular (CC) ostium stenosis (or obliteration) in post-dacryocystorhinostomy (post-DCR) patients.

Material And Methods: The study included 121 patients (127 cases), of which 61 patients (64 cases) had stenosis of the CC ostium and 60 patients (63 cases) had CC ostium obliteration. All stenoses and obliterations were recurrent and developed 6 months to 5 years after primary endonasal endoscopic DCR.
