introduction: ectopic tooth eruption may result owing to one of 3 processes: developmentaldisturbance, iatrogenic activity, or pathologic process, such as a tumor or a cyst. in rare cases, occlusion of the sinus ostia may predispose a patient to develop a maxillary sinus mucocele. when the maxillary sinus is invaded, symptoms usually occur late in the process.   case report: a 17 years old boy ...

We present a case of a foreign body which migrated to the maxillary ostia by mucociliary action from its initial location on the floor of the maxillary sinus where it was traumatically introduced. This report illustrates that a powerful mechanism of mucociliary action can cause relatively heavy objects within the maxillary sinus to migrate naturally to the sinus ostia against gravitational force.

A comprehensive study that compared acoustic rhinometry (AR) data to computed tomography (CT) data was performed to evaluate the accuracy of AR measurements in estimating nasal passage area and to assess its ability of quantifying paranasal sinus volume and ostium size in live humans. Twenty nasal passages of 10 healthy adults were examined by using AR and CT. Actual cross-sectional areas of th...

BACKGROUND Transnasal cannulation of the natural ostium in patients with an intact uncinate process is complicated by the lack of direct visualization of the ostium. Accuracy of transnasal dilation of the maxillary ostium was evaluated for a malleable-tipped balloon device that was bent to specific angles for avoiding the fontanelle during cannulation. METHODS Transnasal cannulation and dila...

BACKGROUND A multicenter study (BREATHE I - Entellus Medical, Inc.) was performed to assess the safety and outcomes of a new, less invasive system that uses direct endoscopic visualization to facilitate balloon dilation of the maxillary sinus ostia and ethmoid infundibulum. General anesthesia was avoided in most subjects to assess feasibility of performing transantral ostial dilatation in an of...
