The variant of a bilateral accessory maxillary ostium may have provided an additional way for mucus to drain in the maxillary sinus, allowing the implant to move into the ethmoidal sinus without ...

The maxillary sinus drains into the nose through a hole called the ostia. When the ostia becomes clogged, sinusitis can occur. The ostia of the maxillary sinus often clog because the ostia are ...

Sinusitis occurs as a result of obstruction of the osteomeatal unit, which is located in the vicinity of the maxillary sinus ostium (Fig. 1). Because of obstruction, mucus accumulates inside the ...

The maxillary sinuses open into the nasal canal through a valve known as the ostium. If mucus membranes in the nasal cavity are swollen, the ostium can become blocked, trapping fluids in the sinus.

A couple of observations about the codes themselves. First, dilation of the maxillary sinus ostium can be achieved by a transnasal (through the nose) or canine fossa approach. If you lifted your lip ...

called the maxillary sinus ostia, open and free of obstruction for 6 months, according to new results from a clinical study presented at the Combined Otolaryngology Spring Meetings in Las Vegas.

The device enables low-pressure, gradual dilation of the maxillary sinus ostia, which is intended to maximize patient tolerability of the procedure in an office setting under local anesthesia.

MATERIAL AND METHODS: Retrospective analysis of the results of FESS performed in 175 patients suffering from paranasal sinus fungus balls. RESULTS: All maxillary (n = 150 ... sinus cavity at the level ...

The maxillary sinus ostia is bounded from below by uncinate process (U) and above by the lower bony portion of ethmoid sinuses (E). A narrowing in this critical area can cause sinusitis.
