In this chapter, we examine the chronic inflammatory diseases of the nasal cavity and paranasal sinuses. First, we examine the basic characteristics of the various chronic inflammatory diseases of the nasal cavity and paranasal sinuses and chronic inflammatory diseases of the oral cavity. Further, we discuss the etiopathogenesis, diagnosis, differential diagnosis, and treatment options for the ...

BACKGROUND Pseudomonas aeruginosa is a pathogen associated with cystic fibrosis that has potential to decrease lung function and cause respiratory failure. Paranasal sinuses are increasingly recognised as potential reservoirs for intermittent colonisation by P. aeruginosa. This case documents investigation and outcome of P. aeruginosa recurrence in a male paediatric patient over an eight year p...

This study aims to determine the relationship between nasal septal deviation, concha bullosa, and chronic rhinosinusitis by using a definitive pathological and simplified model. Fifty-two consecutive sinus computed tomography scans were performed on patients who received endoscopic sinus surgery and whose final diagnosis was paranasal sinus fungus balls. The incidences of nasal septal deviation...

The aim of this study was to evaluate the histopathological findings of unilateral paranasal sinus disease dominated by maxillary sinus opacification on routine non-contrast enhanced paranasal sinus CT. We performed a retrospective analysis of routine paranasal sinus CT conducted between March 2003 and April 2007. Unilateral maxillary sinus opacification (with or without ipsilateral ethmoid or ...

BACKGROUND Sinusitis is a common disease in the horse. In human medicine it is described, that obstruction of the sinonasal communication plays a major role in the development of sinusitis. To get spatial sense of the equine specific communication ways between the nasal cavity and the paranasal sinuses, heads of 19 horses, aged 2 to 26 years, were analyzed using three-dimensional (3D) reformatt...

OBJECTIVE Solitary fibrous tumor is a rare tumor occurring in almost every anatomic location of human body; however, reports of malignant solitary fibrous tumor in the nasal and paranasal area are especially rare. In this report, we describe a case of non-recurrent malignant solitary fibrous tumor of the nasal and paranasal area. METHODS The patient was initially treated with nasal and parana...

Introduction. Complications can occur as a consequence of both acute and chronic sinusitis. Most frequently complications are caused by acute ethmoiditis or frontal sinusitis. The complications of paranasal sinusitis are divided into intraorbital, intracranial and osteomyelitis. The children with complications of paranasal sinusitis require hospitalization, treatment with combined intravenous a...
