Maxillary infundibulum

The maxillary sinuses usually develop symmetrically. The maxillary sinus ostium drains into the infundibulum which joins the hiatus semilunaris and drains into the middle meatus Opacification of sinuses, the size of the maxillary sinus infundibulum, Haller cells, and concha bullosa were evaluated based on computed tomography (CT) images. Simultaneously, nasal airflow resistance was measured. Results: The AR group comprising 105 patients showed maxillary sinus opacification in 45 patients

Maxillary sinus mucociliary drainage flows through the sinus ostium into the infundibulum which joins the hiatus semilunaris and drains into the middle meatus. The middle meatus is also the final drainage for the frontal and anterior ethmoid sinuses The maxillary sinus (or antrum of Highmore) is a paired pyramid-shaped paranasal sinus within the maxillary bone which drains via the maxillary ostium into the infundibulum, then through hiatus semilunaris into the middle meatus. It is the largest of the paranasal sinuses

Chronic maxillary sinusitis rarely causes facial pain except in acute exacerbations. Acute maxillary sinusitis rarely causes facial swelling. Antibiotics are only indicated in acute maxillary.. The maxillary sinus is the cavity behind your cheeks, very close to your nose 1. When a CT scan is taken of the head, the sinuses should show up black since they are cavities. When the area shows up white or gray, it is called opaque or opacification of the sinus The infundibulum can be likened to a hallway, which collects drainage from the frontal, ethmoid, and the maxillary sinus and subsequently directs the secretions medially to the hiatus semilunaris Blockage of sinus: The extremely narrow space allowing air to enter the maxillary sinus (sinus under the eye) and allow drainage from that sinus is called the infundibul.. Abstract Incomplete cemental filling of the infundibula of equine maxillary cheek teeth (CT) is a common feature.

Christina Whyte Maxillary antrostomy may be performed to treat chronic sinusitis. Maxillary antrostomy is a type of surgery for chronic sinusitis.It involves unblocking and/or widening the place where the sinuses drain into the nose, and it clears the sinus opening and relieves congestion. This type of surgery is quite safe, and has only a small risk of complications or adverse effects The main functional component of the maxillary sinus outflow tract is the ostiomeatal complex, which is collectively constituted by the uncinate process, the maxillary ostium, the infundibulum, and the ethmoid bulla. These structures form a functional complex through which the maxillary sinus contents egress

• However, 17 of the 19 hypoplastic maxillary sinuses (89.5%) were associated with lateral displacement of the ethmoid infundibulum relative to the medial orbital wall--8 of the 9 hypoplastic right sinuses and 9 of the 10 hypoplastic left sinuses (figure 2, B)
• Five out of 6 cases showed resolution of clinical signs over a mean follow‐up period of 19 months (range 6-48 months). These cases demonstrate that patency of the infundibular apex is a potential cause of cheek teeth apical infection in young horses, which can be successfully treated by debridement and subsequent infundibular restoration
• In the infundibular pattern, disease is limited to the infundibulum and the adjacent maxillary sinus; the frontal and ethmoid sinuses are preserved. Pathophysiologic causes for this pattern are swollen mucosa, polypoid lesions, and Haller cells. Infundibulotomy is the therapeutic method of choice and produces excellent results in most cases

This concept is easier to understand if one imagine the infundibulum as a prism so that its medial face is the hiatus semilunaris. The lateral face of this infundibulum contains the ostium of the maxillary sinus, which, therefore, opens into the infundibulum The maxillary and facial arteries supply the sinus, and the maxillary vein supplies venous drainage. As mentioned already, the maxillary sinus drains into the ethmoid infundibulum. There is typically only one ostium per maxillary sinus; however, cadaver studies have shown 10% to 30% have an accessory ostium maxillary ostium: drainage channel of the maxillary sinus infundibilum: common channel that drains the ostia of the maxillary (usually on the lateral of the infundibulum between its middle and posterior third), ethmoid sinuses and sometimes the frontal sinuses (depending on configuration of the uncinate process) to the hiatus semilunaris. it is. MAXILLARY SINUS. Maxillary Sinus is an air cavity located within the body of each maxillae. The pyramid-shaped maxillary sinus (or antrum of Highmore) is the largest of the paranasal sinuses, and drains into the middle meatus of the nose. DEVELOPMENT: Development of the maxillary sinus occurs after 3 months of gestation.; After the development of paranasal sinuses the maxillary sinus are.

What Is Total Opacification of the Maxillary Sinus

• The polyp opacifies and slightly enlarges the sinus cavity with no bone destruction. The enlarged antral polyp protrudes through the maxillary infundibulum or accessory ostium into the middle meatus and then the posterior choana, with possible extension into the posterior nasopharynx. Antrochoanal polyps (Figure 9) are rarely bilateral. 2
• The patients usually present with a foul-smelling nasal discharge. When dental amalgam is the cause, the ethmoid infundibulum or the middle meatus may be obstructed and cause rhinosinusitis that mimic the infundibular or OMC patterns.

The presence of maxillary sinusitis, concha bullosa, nasal septal deviation, and infundibular size were recorded. Anatomic variants and infundibular size as well as their relationship with maxillary sinusitis were evaluated using logistic regression. Results: Maxillary sinusitis was diagnosed in 98 (49%) patients, and in 146 of 400 (36.5%) sinuses The frontal and maxillary sinuses open into the nasal cavity not directly, but into a narrow side chamber located here, called the infundibulum. The infundibulum isn't apparent in a bony specimen. We'll see it when we look at the soft tissues. Now we'll look at the openings for the other sinuses After the occlusion of the maxillary infundibulum, the mucous membrane begins to thicken and secretions start to accumulate, progressively increasing inside the sinus. The stagnant mucous is an important stimulus for a low-grade inflammatory response inside the sinus and progressively results in osteolysis of the sinus walls
