OBJECTIVE Paranasal sinus balloon catheter dilation (BCD) represents a commonly used tool in the management of chronic rhinosinusitis (CRS) for which the indications, utilization, and outcomes have not been well established. A systematic review and meta-analysis were undertaken to evaluate change in quality of life and sinus opacification following paranasal sinus BCD in the treatment of CRS. ...

Context The effect on survival of orbital evisceration on patients with paranasal sinus neoplasms has not been well established. Objective To review systematically the available literature concerning survival in patients who undergo surgery for paranasal sinus neoplasm with and without preservation of the eye. Data Source A retrospective meta-analysis of English and non-English articles using M...

We used pipe models to investigate the effects of paranasal sinus ostium size and paranasal sinus volume on the area-distance curves derived by acoustic rhinometry (AR). Each model had a Helmholtz resonator or a short neck as a side branch that simulated the paranasal sinus and sinus ostium. The AR-derived cross-sectional areas posterior to the ostium were significantly overestimated. Sinus vol...

non-penetrating head injuries associated with skull base fractures can lead to the development of pneumocephalus upon airs ingress, which leads its course in the subarachnoid space. intracerebral air accumulation is rare and ensuses when a paranasal sinus fracture is associated with a ensues when a paranasal sinus fracture is associated with a nearby parenchymal contusion. a 25-year old man is ...

Introduction  Many patients undergoing functional endoscopic sinus surgery still have an uncontrolled clinical disease in the late post-operative period. Up to 11.4% of the patients will require a revision surgery. Findings such as the residual uncinated process and the lateralization of the middle turbinate were considered by some studies as being responsible for failure in the primary surgery...

Introduction/Background The paranasal sinuses consist of the maxillary, ethmoid, sphenoid, and frontal sinuses. They communicate with the nasal cavity in the midline and all structures together form a group of air-filled cavities where cancers can arise, grow, and spread without encountering significant barriers to local extension. Cancers of the paranasal sinuses and nasal cavity are rare mali...

OBJECTIVE (1) Become familiar with reported adverse events related to balloon dilation of the paranasal sinus ostia. (2) Understand the sequelae occurring with these events. STUDY DESIGN Retrospective analysis of a prospective database. SETTING OpenFDA database. SUBJECTS AND METHODS The OpenFDA program website of the Food and Drug Administration was queried with the Application Program In...

The current work aimed to analyse the anatomical findings of the nasal and paranasal sinuses of the donkey by gross anatomical observation of the skull and cadaver head, cross-sections, sagittal sections and computed tomography (CT) imaging. Seven adult donkeys and ten skulls were used in this study. The donkey head had six pairs of sinuses, three paranasal; the frontal, maxillary, and sphenopa...

Background and Objectives: Osteomas are the most common benign tumors of nasal cavity paranasal sinuses (PNSs). In this study, clinical features imaging findings were analyzed in patients with osteoma confirmed by ostiomeatal unit (OMU) computed tomography (CT) PNS CT, surgical treatment performed at our hospital was introduced.Methods: The Severance Clinical Research Analysis Portal (SCRAP) se...

BACKGROUND We hypothesized that higher body mass index (BMI) was associated with increased prevalence of paranasal sinus disease and examined the hypothesis in Japanese adults. METHODS This was a cross-sectional study including 1350 Japanese adults aged 40 years or more who participated in a health check-up program focusing on brain diseases and metabolic syndrome. Participants were divided i...
