Introduction: The study was conducted to asses if septoplasty is adequate for the management of chronic maxillary sinusitis. Chronic maxillary sinusitis is not uncommonly associated with deviated nasal septum (DNS). The randomized study was conducted on 40 cases of medically unmanageable and HRCT proven chronic maxillary sinusitis with DNS. Materials and methods: The study was conducted in 40 c...

Unmanned aerial vehicles (UAVs) have attracted much attention lately and are being used in a multitude of applications. But the duration sky remains to be an issue due their energy limitation. In particular, this represents major challenge when UAVs as base stations (BSs) complement wireless network. Therefore, execute missions sky, it becomes beneficial wirelessly harvest from external adjusta...

BACKGROUND There is a need to find an animal model to study new medications to improve mucosal wound healing after functional endoscopic sinus surgery (FESS). Current literature suggests swine as a potential candidate. The lack of information correlating swine computer tomography (CT) and endoscopic sinonasal anatomy prompted us to investigate them in the domestic and Yucatan swine to determine...

OBJECTIVE In this report, we presented a rare case of bilateral silent sinus syndrome (SSS) in an otherwise healthy 57-year-old man treated with functional endoscopic sinus surgery (FESS). A systematic review of the literature regarding bilateral SSS was performed. CASE REPORT A 57-year-old man with well-controlled allergic rhinitis in the absence of previous surgery or trauma presented with ...

The main disadvantage of conventional functional endoscopic sinus surgery (FESS) for the surgeon is the restriction to one hand for manipulation while the other hand is holding the endoscope. In our project we develop an automatic anticipating robot assisted endoscope guidance during FESS. The robot guidance will be realized by a multisensor system which includes tactile control. The objective ...

Flywheel energy storage systems (FESS) are considered as the grid integration of renewable sources due to their buit-in advantages such fast response, long cycle life and flexibility in providing auxiliary services grid, frequency regulation, voltage support. This paper introduces structure comparison results matrix converter back-to-back which integrated with axial flux permanent magnet motor ...

introduction: the surgical management of chronic frontal sinus disorders remains a challenge for rhinologists. the aim of this study was to evaluate the result of draf iii in a series of patients who underwent this procedure.   materials and methods: twenty patients were included in this study. demographic data, history of prior surgery, asthma,  aspirin sensitivity and lund–mackay score were r...

the relationship between asthma and sinusitis has been proposed in many reports but the role of sinus surgery in their treatment is still controversial. therefore, the effect of functional sinus surgery in patients with controlled asthma was evaluated. fifty six patients with a history of sinusitis in whom maximum medical treatment had failed and also those with a history of asthma who were in ...

INTRODUCTION Bleeding is a common concern during functional endoscopic sinus surgery (FESS) that can increase the risk of damage to adjacent vital elements by reducing the surgeon's field of view. This study aimed to explore the efficacy of topical tranexamic acid in reducing intraoperative bleeding. MATERIALS AND METHODS This double-blind, randomized clinical trial was conducted in 60 patien...

BACKGROUND A strong ongoing intraoperative stress response can cause serious adverse reactions and affect the postoperative outcome. This study evaluated the effect of intranasally administered dexmedetomidine (DEX) in combination with local anesthesia (LA) on the relief of stress and the inflammatory response during functional endoscopic sinus surgery (FESS). METHODS Sixty patients undergoin...
