Herein we report our experience with a simple technique for reducing the rate of silicone tube extrusion after nasolacrimal duct (NLD) intubation for congenital NLD obstruction. Medical records of children older than 2 years, with or without history of failed probing, who had undergone NLD intubation with a Crawford silicone tube over a period of 4 years were reviewed. In all subjects, one end ...

Background: A purposely designed wire reinforced silicone tube is available for tracheal intubation through intubating laryngeal mask airway (ILMA). However, this tube is expensive and not always available. Hence, cheaper and readily available alternatives such as conventional polyvinyl chloride (PVC) endotracheal tube should be evaluated for intubation through ILMA. Methods: After informed con...

  Despite promising results observed using silicone rubber chamber, no previous comprehensive work was performed on behavior of the conduit. Present study aimed at further functional, histomorphometrical and immunohistochemical assessment of nerve regeneration in the same animal along a 10-mm rat sciatic nerve gap. Fifty- four male Wistar rats were divided into three experimental groups (n = 1...

BACKGROUND Tracheal stenosis or tracheal injury is a troublesome disease. Traditional temporary tracheostomy and reconstruction can resolve some problems. However other problems such as subglottic stenosis and supracarinal stenosis, cannot be resolved by simple tracheostomy. The silicone tracheal T-tube presents a substitute for stent of this complicated disease. METHODS Eleven patients with ...

BACKGROUND To describe one modified method of having machine-independent removal of 5,000 centistokes silicone oil through 23-gauge trocar-cannulas. METHODS Consecutive patients with silicone oil tamponade for more than four months and with complete retinal reattachment were included. Two 23-gauge trocars were used to make sclerotomies while the microcannulas remained in situ for intravitreou...

excessive scarring; paralleling the process in tendon reconstruction of the hand. inspired by the advantages of the two-stage technique in tendon grafting and with encouraging preliminary results, we aimed to investigate the two-stage nerve grafting technique as an alternative method of secondary nerve repair. methods:  thirty female rats (~200 g) were randomly distributed into two groups (n=15...

PURPOSE Dacryoscintigraphy is widely known to be an effective modality in diagnosing abnormalities of the lacrimal system that cause epiphora (pathological overflow of tear). However, dacryoscintigraphy rarely serves beyond the simple diagnostic use for lacrimal duct obstruction. In our study, dacryoscintigraphy results of patients with functional lacrimal duct obstruction are newly classified ...

INTRODUCTION The Montgomery silicone tracheal T-tube (Safe-TTube) has gained a role in laryngeal and tracheal reconstruction and revision by providing patients a longterm, indwelling stent that allows voice production and swallowing. Montgomery designed the tracheal T-tube in 1968.l The T-tube is made of silicone and therefore relatively inert and resistant to tissue reaction.2 It can be used f...

A cannulated probe and silicone tube for the repair of the torn inferior canaliculus are described and illustrated.
