Safety of sphenoid aspiration for diagnosis and treatment of intensive care unit rhinosinusitis

[The evolution of methods of active irrigation of paranasal sinuses in rhinosinusitis. Part 1]

Inflammation of the paranasal sinuses significantly reduces the quality of life of people and causes marked economic damage to society. The striking clinical picture of sinusitis has always forced doctors to study the disease, as evidenced by the first records of the anatomy and diseases of the paranasal sinuses by doctors in ancient Egypt more than 3.000 years BC. Sinusitis has been treated in different ways in different historical periods. Effective medication treatment appeared relatively recently and began to steadily replace the older instrumental methods, to which many people had a preconceived notion of invasiveness. However, many studies are showing the positive effect of active drainage methods and, moreover, there is data showing that the discomfort during such procedures is slightly higher than during dental treatment under local anesthesia. This article presents a review of the available scientific literature on the use of different treatments for bacterial rhinosinusitis at different historical stages, ranging from the first publications on puncture techniques to balloon dilatation and the modern approach to conservative treatment.

The prevalence of bacterial infection in acute rhinosinusitis: a Systematic review and meta-analysis

OBJECTIVES/HYPOTHESIS

To systematically assess the prevalence of bacterial infection in adults with acute rhinosinusitis (ARS).

METHODS

Electronic databases were systematically searched for relevant studies published up to June 2012.

RESULTS

Twenty-nine articles, evaluating a total of 9,595 patients with a clinical diagnosis of ARS, were included in the study. Of these, 14 (48%) studies required radiographic confirmation of sinusitis, one study (3%) required evidence of purulence, 10 studies (35%) required both for inclusion in the study population, and four studies (14%) required neither. The random effects model estimate of prevalence of bacterial growth on all cultures was 53.7% (CI 48.4%-59.0%), ranging from 52.5% (CI 46.7%-58.3%) in studies requiring radiographic confirmation of sinusitis to 61.1% (CI 54.0%-68.1%) in studies requiring neither radiographic evidence nor purulence on exam. Studies that obtained cultures from antral swab had a prevalence of bacterial growth of 61.0% (CI 54.7%-67.2%), whereas those utilizing endoscopic meatal sampling had a prevalence of 32.9% (CI 19.0%-46.8%).

CONCLUSIONS

Few studies evaluate the recovery of bacteria via culture in adults with a diagnosis of ABRS or ARS based on clinical criteria alone. With radiographic and/or endoscopic confirmation, antral puncture and endoscopically guided cultures produce positive bacterial cultures in approximately one-half of patients. Opportunities exist to improve diagnostic accuracy for bacterial infection in ARS.

Extracranial head and neck infections

This article outlines infections in the submandibular, lateral pharyngeal, retropharyngeal, danger, and prevertebral spaces, in conjunction with infections of the sinuses and mediastinum. By understanding the anatomy and pathophysiology, the reader will gain insight into the rationale for various therapeutic options.
