Piezosurgery in endoscopic dacryocystorhinostomy
2009
Piezosurgery is a recently developed system for cutting bone with microvibrations. The equipment consists of two hand pieces, two inserts, and two peristaltic pumps connected to the control unit. The device is endowed with an irrigation system of high-flow saline solution that breaks up into very small particles, with a “bloodless” effect on the surgical site and a low indirect thermal damage to the bone surfaces and adjacent structures. 4,5 The touch screen of the main unit permits selection of the specific insert, and modulation of the irrigation and the power according to the bone density. The device uses low-frequency ultrasonic waves (24.7-29.5 kHz), the applied power can be modulated …
Dacriocistitis por Candida Lusitaniae
2007
espanolCaso clinico: Se presenta el caso de una mujer de 60 anos con episodios recurrentes de dacriocistitis aguda derecha que no cedian con tratamiento medico ni tras una dacriocistorrinostomia con intubacion bicanalicular. Presento tambien una dacriocistitis izquierda que requirio una dacriocistorrinostomia. Se tomaron muestras intraoperatorias y en el cultivo aparecio Candida Lusitaniae como germen responsable. Tras tratamiento topico con Anfotericina B, asociado a dacriocistorrinostomia, la clinica desaparecio. Discusion: La dacriocistitis por Candida Lusitaniae es muy rara. Cabria preguntarse si Candida Lusitaniae es el germen primario o la dacriocistitis podria ser por sobreinfeccion …
Epiphora Secondary to Blockage of the Lacrimal System: The Role of Endonasal Dacryocystorhinostomy
1994
Stenosis of the lacrimal system may occur secondary to tumor, infection, trauma, and congenital etiologies. Attempts to remedy this problem often include irrigation and probing. However, if these fail, external or internal dacryocystorhinostomy (DCR) with or without stenting may be performed. The purpose of this article is to detail our experience with a microscopic endonasal approach to DCR utilized in 23 patients. This is a modification of an older accepted procedure which utilizes the modern techniques of endonasal sinus surgery. This approach has allowed for immediate restoration of drainage in 22 of 23 cases. In one case, the procedure was repeated because of restenosis at the level o…
