View clinical trials related to Endoscopic Sinus Surgery.
Filter by:The study aimed to compare the applicability of the classic lateral lamellectomy versus the submucosal conchoplasty techniques in managing the concha bullosa during and after ESS.
Various drugs have been used for the purpose: nitroglycerine, sodium nitroprusside, propofol, beta blockers, calcium channel blockers, higher concentrations of inhalational anesthetics etc. Since all these drugs have certain limitations there was a search for more safe and effective drug
Chronic sinusitis (CRS) is a high incidence disease characterized by pus, nasal obstruction, olfactory disturbance, headache, and other symptoms, lasting for more than 12 weeks, with severe cases having ocular compression and visual impairment, which can cause cranial, eye, and lung complications. Chronic sinusitis is a high-risk disease.
Functional endoscopic sinus surgery (FESS) is the pimary surgical treatment of CRS, characterized with the preservation of nasal structure and function.But the control of disease by surgery has been unsatisfactory. Recent studies have shown that patients with recurrent CRSwNP (usually with severe eosinophilic inflammation), more radical surgery may be more effective. The purpose of this prospective and randomized study is to determine the effect of endoscopic sinus surgery for extensive mucosal removal in patients with eosinophilic chronic rhinosinusitus with nasal polyps.
The study aims to compare the effect of addition of verapamil and Bisoprolol to general anasthesia aimed reduction in heart rate and blood loss during endoscopic sinus surgery.
Endoscopic Sinus surgery usually associated by bleeding, despite using of local vasopressor injection, head up position- controlled hypotension is generally used for control of this purpose. Propofol has been reported as a good agent for controlled hypotension by decreasing systemic vascular resistance secondary to arterial and venous vasodilation and a decrease in myocardial contractility with a dose-dependent property. Magnesium Sulfate also has been reported as an agent of hypotensive anaesthesia by inhibition of the release of norepinephrine by blocking N-type calcium channel at the nerve ending beside acting as a vasodilator. The well known pharmacodynamic effects of the intravenous infusion of propofol or Magnesium Sulfate may prove the advantage of this group in controlling intraoperative blood pressure thus reducing surgical field bleeding.
The aim of this randomized trial is to assess the utility of Pupillary Dilatation Reflex (PRD) for monitoring pain perception intraoperatively and its influence on intraoperative blood loss, quality of surgical field using Boezaart Bleeding Scale (BBS) in patients undergoing functional sinus surgery (FESS) under total intravenous anaesthesia using propofol or volatile anaesthesia using sevoflurane or desflurane
The aim of this randomized trial is to assess the utility of Surgical Pleth Index (SPI) for monitoring pain perception intraoperatively and its influence on intraoperative blood loss, quality of surgical field using Boezaart Bleeding Scale (BBS) in patients undergoing functional sinus surgery (FESS) under total intravenous anaesthesia using propofol or volatile anaesthesia using sevoflurane or desflurane
The aim of this randomized trial is to assess the efficacy of analgesia , compare the utility of Pupillary Dilatation Reflex (PRD), Surgical Pleth Index (SPI) for monitoring pain perception intraoperatively and their influence on intraoperative blood loss, quality of surgical field using Boezaart Bleeding Scale (BBS) in patients undergoing functional sinus surgery (FESS)
The purpose of this investigation is to conduct a randomized controlled trial within a subgroup of difficult-to-treat patients with CRS, evaluating the use of topical xylitol treatment concurrently with topical steroid/antibiotics combination in the effort to disrupt biofilms and improve disease control. The effectiveness of topical surfactants is a research gap in treating CRS but has promising correlates in other medical fields. Specifically, the investigators will be studying the effect of topical xylitol therapy on biofilm production with the use of PCR bacterial sequencing before and after medical intervention.
