The XprESS multi-sinus dilation system (XprESS) is a minimally invasive alternative to functional endoscopic sinus surgery (FESS) used in the treatment of people with chronic or recurrent acute sinusitis refractory to medical treatment. The manufacturer of XprESS, Entellus Medical, claims the technology is as effective as FESS in improving quality of life and is associated with quicker recovery...

OBJECTIVE To observe the effect of lamina papyracea ingression on orbito-ocular complications after functional endoscopic sinus surgery (FESS). METHODS Data of computed tomography (CT) and post-FESS complications were analysed in 483 patients undergoing FESS from October 2013 to November 2015. According to the condition of lamina papyracea, these patients were divided into lamina papyracea in...

An increasing number of patients are opting for combining sinus surgery and cosmetic rhinoplasty. The author has been performing rhinoplasty with FESS since April of 1990. The technique and equipment used in early cases is much different than that used in more recent surgeries. Specific advances include high definition monitor, intraoperative navigation system, and powered dissecting instrument...

Introduction: The major presenting symptom of nasal polyps is nasal obstruction. The role of nasal obstruction in the genesis of laryngeal disorders is still unknown.   Materials and Methods: The aim of this study was to evaluate laryngeal videostroboscopic changes after functional endoscopic sinus surgery (FESS) in patients with nasal polyposis. A longitudinal study was carried out from M...

HYPOTHESIS Use of dressings in the middle meatus after functional endoscopic sinus surgery (FESS) improves clinically meaningful outcomes in patients with chronic rhinosinusitis (CRS).

The paper reports on the investigation and development of the flywheel device as a energy storage system (FESS). The FESS is designed to operate in a vacuum and is supported on a low energy controlled active magnetic bearings (AMBs). The goal was to design and experimentally test the self integrated flywheel conception with a smart control of the flywheel rotor magnetic suspension. The low powe...

This paper evaluates the concerns relating to the forecasted higher penetration of renewable energy within the power grid as it pertains to frequency variations. This is addressed by implementing fast-acting energy storage systems (FESS) at an ideal location within the system. The location is determined through visualizing and analyzing changes in frequency following an event. This study was ca...

Antibody immunodeficiencies are common in patients with chronic rhinosinusitis (CRS) and associated recurrent sino-pulmonary infections. The role of functional endoscopic sinus surgery (FESS) has not been established the management these infections clinical guidelines suggest caution surgery. This study evaluates number antibiotic courses for radiographic disease severity after FESS CRS antibod...
