Introduction: The incidence of orbital subperiosteal abscess (OSA) in pediatric population is 15% of the orbital infections, being acute sinusitis the most frequent cause of this complication. The diagnosis of OSA is based on clinical examination and imaging. Treatment usually includes IV antibiotics, nasal decongestants and surgical drainage if necessary. If inadequately treated, orbital cellu...

Background: Ivabradine is an effective drug to prevent abnormal increase in heart rate (HR). Aims and Objectives: The aims of this study were determine if a pre-operative oral dose ivabradine (2.5 mg) reduces intraoperative bleeding during functional endoscopic sinus surgery (FESS) improves visualization operative field. Materials Methods: A prospective, randomized, placebo-controlled was carri...

C hronic rhinosinusitis (CRS) is one of the most expensive chronic disorders experienced by the North American population. It is estimated to affect nearly 15% of the US population. Its prevalence is reported to be increasing, thereby attributing to the rise in today’s health care costs. Allergic fungal rhinosinusitis (AFRS), a subtype of CRS, accounts for approximately 7% of all CRS patients r...

BACKGROUND Controlled induced hypotension guarantees less blood loss and better visibility of the surgical site. The impact of hypotension on post-operative cognitive functions is still being discussed. The objective of this study was to evaluate the effects of controlled induced hypotension on the cognitive functions of patients undergoing functional endoscopic sinus surgery (FESS). MATERIAL...

The University of Texas at Austin Center for Electromechanics (UT-CEM) is currently developing an Advanced Locomotive Propulsion System (ALPS) as part of the Next Generation High-Speed Rail program sponsored by the Federal Railroad Administration (FRA). The ALPS consists of a gas turbine and synchronous alternator, combined with an induction motor coupled flywheel energy storage system (FESS). ...

Introduction There is change in nasalance post endonasal surgery which is not permanent. Objectives The objective of this study is to evaluate the long-term nasalance changes following different types of endonasal surgeries. Methods We included in this study patients who underwent sinonasal surgery at the Otorhinolaryngology Department in Zagazig University Hospitals from February 2015 until Ma...

Although much has been reported on the short-term outcomes of functional endoscopic sinus surgery (FESS), little has been reported with regard to its long-term impact on chronic sinusitis. The senior author (D.W.K.) previously reported detailed subjective and endoscopic follow-up on 120 patients at a mean of 18 months following surgery. This current study represents a long-term follow-up (avera...

OBJECTIVE To determine whether the 15-degree reverse Trendelenburg position (RTP) during functional endoscopic sinus surgery improves endoscopic field of view and reduces intraoperative blood loss when compared with the horizontal position (HP). STUDY DESIGN A prospective, randomized controlled trial. SETTING St Paul's Sinus Centre, Vancouver, Canada. SUBJECTS Patients with chronic rhinos...

OBJECTIVE To evaluate the prevalence of human herpesviruses (HHV) 1-6 and community-acquired respiratory viruses (CARVs) in specimens from patients with nasal polyposis undergoing functional endoscopic sinus surgery (FESS) and investigate the potential clinical role. METHODS Viral occurrence was evaluated by molecular methods in polyp, turbinate mucosa, and pre- and postoperative scraping spe...
