purpose: to compare the success rate of external dacryocystorhinostomy (dcr) with and without bicanalicular silicone intubation for the management of primary acquired nasolacrimal duct obstruction. methods: in this study, 51 eyes from 50 patients who were diagnosed with primary acquired nasolacrimal duct obstruction underwent external dcr. patients with history of trauma and/ or surgery in the ...

INTRODUCTION Ocular injuries commonly involve the lacrimal system. CASE A 14-year-old male had an eyelid injury with a canalicular tear. An angiocatheter tube was used as a stent for canalicular reconstruction. The focus of this report is on the method used, as well as the material for the repair in a rural hospital. CONCLUSION Angiocatheter tube can be a suitable alternative to silicone tu...

BACKGROUND The design of an endotracheal tube has been shown to influence the passage of the tube through the glottis during fiberoptic intubation. Difficulty in passing the endotracheal tube can occur if the aryepiglottic folds obstruct the passage of the bevel. The relevant aspects of endotracheal tube design include the shape of the bevel, the material used by the manufacturer, and the abili...

The diagnosis and treatment of patulous eustachian tube were discussed with review of the literature. In addition, some new findings from the author's group related to this difficult disorder were presented. We have used 3-dimensional reconstruction of the computed tomography (3D-CT) of the eustachian tube lumen to detect very severe cases of the patulous eustachian tube. The new treatment of t...

PURPOSE To compare the success rate of monocanalicular versus bicanalicular silicone intubation of the nasolacrimal duct for congenital nasolacrimal duct obstruction (CNLDO). METHODS In a prospective randomized clinical trial, 70 eyes of 57 children with CNLDO underwent either monocanalicular silicone intubation (MCI) (n = 35 eyes) or bicanalicular silicone intubation (BCI) (n = 35 eyes). All...

Mechanical forces play an important role in shaping the organization of the extracellular matrix (ECM) in developing and mature tissues. The resulting organization gives the tissue its unique functional properties. Understanding how mechanical forces influence the alignment of the ECM is important in tissue engineering, where recapitulating the alignment of the native tissue is essential for ap...

Objective: The use of a T-tube to manage complex laryngotracheal lesions, such as tracheal stenosis, tracheomalacia and tracheal injury, has previously been reported by other surgeons in the past. However, further validation of clinical details, including operative management and postoperative care, is needed. Methods: From January 1991 to May 2000, 53 patients, including 24 with post-tracheost...

An innovative use of a fenestrated silicone drainage tube as an endobronchial stent is reported. The patient had respiratory obstruction due to a carinal tumour and laser photoresection had failed to restore airway patency.
