The maxillary sinus ostium is the natural opening through which the maxillary sinus, the large air-filled cavity within the cheekbone, drains and ventilates into the nasal cavity. It connects the sinus to the middle nasal meatus by way of a narrow channel, allowing mucus to clear and air to circulate. Because the ostium is small and positioned high on the medial wall of the sinus, it is prone to obstruction by swelling, polyps, anatomical variation, or inflammation, and any blockage can impair drainage and lead to mucus retention and recurrent or chronic sinusitis. Its precise location and dimensions are clinically important in the diagnosis and surgical management of sinus disease, particularly in functional endoscopic sinus surgery, and these features are commonly assessed using imaging such as computed tomography and cone-beam computed tomography. Research relevant to this topic in the journal Otolaryngology Advances includes a cone-beam computed tomography study determining the location and diameter of the primary maxillary sinus ostium in a Malaysian population, providing anatomical reference data of direct relevance to sinus surgery and diagnosis. This page gathers peer-reviewed, open-access research relevant to the maxillary sinus ostium and sinonasal anatomy.
