Silent sinus syndrome is a subtype of stage three chronic maxillary atelectasis. The distinguishing factor is that in silent sinus syndrome, there is an absence of sinusitis symptoms. [ 3 ] [ 4 ] [ 5 ] To be clear, chronic maxillary sinusitis may be a primary causitive factor in a significant number of silent sinus syndrome cases, it just may ...

Maxillary hypoplasia is the most common secondary deformity that results from cleft lip and cleft palate. Because of the subjective nature of the diagnosis, the incidence of maxillary hypoplasia in people with cleft lip and palate varies between 15-50%. It is estimated that 25-50% of these patients require surgical intervention. [7]
Ultrasonography machine: uses ultrasound to produce images from within the body; video link: X-ray: uses X-rays to produce images of structures within the body; video link: Contrast media for X-rays: to provide a high contrast image of the details of the viscera under study; e.g. salts of heavy metals, gas like air, radio-opaque dyes, organic ...
Maxillary sinuses are more radiolucent than orbits. Maxillary sinusitis [2] Differentiating pathology in maxillary sinus. Maxillary sinus shows radiopacity. [2] Mucous membrane shows thickening. [2] Air-fluid level may be observed if the radiograph is taken in "head-up" position. [2] It is not seen in radiograph taken in lying down position.
Recent studies have classified two types of maxillary sinus septa: primary and secondary. Primary septa are those initially described by Underwood and that form as a result of the floor of the sinus sinking along with the roots of erupting teeth; these primary septa are thus generally found in the sinus corresponding to the space between teeth, as explained by Underwood.
The pyramid-shaped maxillary sinus (or antrum of Highmore) is the largest of the paranasal sinuses, located in the maxilla. It drains into the middle meatus of the nose [ 1 ] [ 2 ] through the semilunar hiatus .
The maxillary hiatus (also known as maxillary sinus ostium, maxillary ostium, or opening from the maxillary sinus) [citation needed] is the opening of a maxillary sinus into the middle nasal meatus of the nasal cavity.
