OBJECTIVE The aim of this study was to find out the efficacy of a polyvinyl alcohol (PVA) sponge (Merocel Kennedy; Medtronic Xomed, Jacksonville, Florida) sinus pack soaked with levobupivacaine hydrochloride to control postoperative pain and analgesic need following functional endoscopic sinus surgery (FESS). STUDY DESIGN The study was designed as a prospective, double-blind, randomized, cont...

The aim was to evaluate the effects of Functional Endoscopic Sinus Surgery (FESS) on nasal aerodynamic flow patterns using Computational Fluid Dynamics (CFD) simulations. A 3-dimensional model of nasal cavity was first constructed from CT scans of a human subject with FESS interventions on left nasal cavity. Computational fluid dynamics (CFD) simulations were then carried out for unsteady airfl...

OBJECTIVE The complication rates associated with different types of functional endoscopic sinus surgery (FESS) remain to be fully examined. STUDY DESIGN Retrospective cohort study. METHODS We extracted data from the Japanese Diagnosis Procedure Combination database on 50,734 patients (aged ≥ 16 years) who underwent FESS for chronic rhinosinusitis between 2007 and 2013. We focused on specifi...

This study retrospectively analyses paranasal sinus complications following displacement of oral implants in the maxillary sinus treated according to clinical situation by functional endoscopic sinus surgery (FESS), an intraoral approach, or a combination of both procedures. Over 5 years, 27 patients (13 male; 14 female), aged 27-73 years (mean 53.9 years), underwent treatment for postoperative...

RATIONALE The European Position Paper on Sinusitis (EPOS) guidelines provide composite criteria to evaluate chronic rhinosinusitis (CRS) control, taking into consideration the severity of patients' symptoms, aspect of nasal mucosa and medical intake as parameters of CRS control. OBJECTIVES To study the degree of CRS control using novel EPOS control criteria at 3-5 years after a functional end...

OBJECTIVES To provide a systematic review of the clinical effectiveness of endoscopic sinus surgery (ESS) for the removal of nasal polyps. DATA SOURCES Searches of electronic databases, websites and reference lists were made to identify relevant studies. REVIEW METHODS An extensive search was performed to identify all articles where FESS is used for the excision of nasal polyps. Two reviewe...

Chronic rhinosinusitis (CRS) is not a life-threatening disorder but may have a great impact on the patients. This study intended to evaluate the impact of functional endoscopic sinus surgery (FESS), and compare the effect and quality of life (QOL) after two different surgical approaches on patients with CRS. Sixty patients of CRS were analyzed before and after FESS. The extent of disease was ev...
