Airflow In Paranasal Sinuses

Importance of Paranasal Sinuses in Computational Modeling of Nasal AirFlow

This paper investigates the importance of including paranasal sinuses in the computational modeling of the nasal airflow. Three dimensional models of human nasal airway with and without including paranasal sinuses were reconstructed from Computed tomography (CT) axial images of a subject with healthy nasal airway. The reconstruction process was performed using MIMICS® software program. The airw...

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...

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 Fungal Balls in Children

Objective: Rare cases of fungal balls of paranasal sinuses in children. No case has been reported in young children so far. However, allergic aspergillosis has been reported in young children. Method: A case report of 2 cases of fungal balls of paranasal sinuses in children and review of the current literature concerning fungal balls of paranasal sinuses in children are presented. Result: 2 cas...
