PURPOSE To evaluate the efficacy of a sleeve technique during endoscopic dacryocystorhinostomy (DCR) in primary nasolacrimal duct obstruction (NLDO) patients with a high lacrimal sac. MATERIALS AND METHODS The medical records of 45 patients (49 cases) undergoing endoscopic DCR for primary NLDO with a high lacrimal sac were retrospectively reviewed. In 19 patients (21 cases), the thick maxilla...

BACKGROUND Interpositional jump graft (IPJG) is a nerve graft axonally supercharged from the hypoglossal nerve. However, for using the technique, an autologous nerve, which should contain the great auricular and sural nerves, must be obtained. Depending on the donor site, unavoidable issues such as nerve disorders and postoperative scarring may appear. To reduce the issues, in this study, the a...

BACKGROUND The most common cause of skin graft failure is the collection of blood or serous fluid underneath the graft. In our study, we describe the use of silicone tube for tie-over dressing to secure the skin graft margins with the aim of decreasing loss of the skin graft, particularly in grafting of deep wounds. METHODS Between March 2008 and July 2011, we used this technique in 17 patien...

PURPOSE To investigate the efficacy of lacrimal silicone intubation for the management of epiphora in patients who have previously undergone anatomically successful dacryocystorhinostomy (DCR). METHODS The authors recruited 13 patients (4 male, 9 female) who had persistent epiphora after an anatomically successful primary external DCR and conducted lacrimal silicone intubation through the dac...

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...

203 Abstract: Semi-thin and thin sections were used to observe the morphogenesis of peripheral nerves regenerating in silicone tubes. The progress of peripheral nerve regeneration across a 10 mm gap within the silicone tubes was examined after 3, 6 and 9 months. The left sciatic nerves of rats were transected. The proximal and distal nerve stumps were inserted into a silicone tube, in which the...

This experimental study investigated the back pressure (P(back)) versus flow (U) relationship for 10 different tubes commonly used for semi-occluded vocal tract exercises, that is, eight straws of different lengths and diameters, a resonance tube, and a silicone tube similar to a Lax Vox tube. All tubes were assessed with the free end in air. The resonance tube and silicone tube were further as...

BACKGROUND To compare the frequency of appearance of complications, anatomical success and functional success after conventional endoscopic dacryocystorhinostomies (EN-DCRs) or EN-DCR with otologic T-Type ventilation tube combined with silicone tube intubation in repeated revision cases. METHODS Twenty-two patients who had epiphora and recurrent dacryocystitis after at least a previous failed...

BACKGROUND Peripheral nerve repair outcomes are suboptimal in the presence of severe soft tissue injury and 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 se...
