Clinical Observation of Fungus Infection of Paranasal Sinuses

Fungus balls of the paranasal sinuses.

Fungus balls of the paranasal sinuses represent a noninvasive manifestation of fungal sinusitis. Patients are immunocompetent but no more allergic than the general population. There is little tissue reaction to the tangled mat of hyphae. If the patient becomes immunocompromised, then the fungus ball may become invasive, as illustrated by an included case report. One hundred sixty-three addition...

Disorders of the Paranasal Sinuses

Inflammation of the equine paranasal sinuses is a relatively uncommon disease that may be caused by primary bacterial or mycotic infections (Mason 1975a), or can be secondary to dental disease (van der Velden & Verzijlenberg 1984, Scott 1987, Tremaine & Dixon 2001a), facial trauma, sinus cysts, progressive ethmoid hematoma or sinonasal neoplasia (Mansmann & Wheat 1973, Gibbs & Lane 1987, Tremai...

Mucoceles of the paranasal sinuses.

Actinomycosis of the paranasal sinuses.

Actinomycosis is a chronic suppurating granulomatous disorder specific to soft tissue. It is produced by Actinomyces Israelii, gram positive anaerobic bacteria that are very difficult to culture, and a commensal saprophyte of the oral cavity (tonsillar crypts, saliva and gingival dental sulci) and the gastro-intestinal tract; it becomes a pathogen in the face of erosions of the oropharyngeal mu...

Paranasal sinuses malignancies: A 12-year review of clinical characteristics

BACKGROUND Inadequate epidemiologic investigations of the paranasal sinuses malignancies prompted this retrospective study with special emphasis on a major group of 111 tumors. MATERIAL AND METHODS Clinical records of 111 patients with histologically confirmed malignant tumors of the paranasal sinuses were investigated retrospectively from April 2000 to January 2012. Collection of data includ...
