Transnasal Endoscopic Surgery in Retro-orbital Abscess
Introduction: Transnasal endoscopic approach is well established in the management of subperiosteal abscess but retro-orbital abscess is commonly treated by external surgical approach. There are only two articles published on endoscopic drainage of retro-orbital abscess. We present our experience in the management of retro-orbital abscesses by transnasal endoscopic surgery. Methods: Retrospecti...

متن کاملComparative analysis of dosimetric parameters of three different radiation techniques for patients with Graves’ ophthalmopathy treated with retro-orbital irradiation
BACKGROUND We would like to investigate the if IMRT produced better target coverage and dose sparing to adjacent normal structures as compared with 3-dimensional conformal radiotherapy (3DCRT) and lateral opposing fields (LOF) for patients with Graves' ophthalmopathy treated with retro-orbital irradiation. METHODS Ten consecutive patients diagnosed with Graves' ophthalmopathy were prospective...
متن کاملMediastinal and Retro-orbital emphysema following an uncomplicated endoscopic sphincterotomy
We report a case of mediastinal and bilateral retro-orbital emphysema following an uncomplicated endoscopic sphincterotomy. The concurrent presence of these complications following endoscopic retrograde cholangiopancreatography is rare. The simultaneous occurrence of these two complications in the same patient has not been previously reported in the literature. Furthermore, we define the first ...
متن کاملMeasurement of the immobilisation efficacy of a head fixation system
Background: In order to assign appropriate planning target volume (PTV) margins, each centre should measure the patient positioning deviations for their set-up techniques. At the Royal Marsden Hospital, UK, a conformal shell (cast) system is used when a stereotactic frame is not suitable. In this paper, we report on a series of measurements with the aim of obtaining the systematic and random ...
