Pars plana vitrectomy (PPV) was introduced almost 40 years ago. 1 In the 1980s and 1990s, three-port PPV with 20-gauge (G) instruments was the norm. In 2002, 25-gauge transconjunctival sutureless vitrectomy (TSV) was introduced.2,3 This system permits threeport PPV using microcannulas, trocars, and 25-G instrumentation without requiring sutures to close the sclerotomies. Subsequently, a similar...

BACKGROUND The sutureless pars plana vitrectomy (ppv) using a 25-gauge instrumentation is a minimally invasive technique which is mainly performed for procedures that do not require extensive vitreous dissection. In a consecutive case series with retrospective collection of data, the advantages and the risks of this technique are discussed in comparison with the conventional 20-gauge ppv for pa...

Pars plana vitrectomy is one of the most common surgical procedures performed for the treatment of various vitreo-retinal diseases such as retinal detachment, vitreous haemorrhage, proliferative diabetic retinopathy, epiretinal membrane and macular hole. Traditionally, most vitrectomy surgical systems utilise the 20-gauge instruments pars plana vitrectomy includes multiple incisions including p...

Purpose To analyze the location of the femoral tunnel by three-dimensional computed tomography (3D CT) of the lateral condyle in patients who underwent arthroscopic single-bundle anterior cruciate ligament (ACL) reconstruction, performed using a modified transtibial technique, and to compare the results with data from the literature. Materials and Methods Seventeen patients with ACL lesions u...

PURPOSE The purpose of this study was to evaluate intraobserver and interobserver reliability of anterior cruciate ligament tunnel location measurement by use of 3-dimensional reconstructed computed tomography (CT). METHODS Three-dimensional reconstructed CT images of 31 cadaveric knees were used in this study. Twenty-one knees were operated on with a double-bundle technique, and ten knees we...

With the large-scale construction and rapid development of underground engineering, a large number of underground engineering construction, such as tunnel and subway emerged. The geological structure of the tunnel is complex and the roc is fragmented. Tunnel seismic image is a new geophysical technique. This method has advantages such as high resolution, high reliability and obvious image chara...
