2025年1月14日 · 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.

• Standard coronal CT is INADEQUATE to understand 3D sinus anatomy, particularly in the frontal recess • Axial thin section (<1mm) helical CT • Axial, coronal, and sagittal reconstruction (3 mm thick or less) • Bone and soft tissue windows • Patients should only be scanned after a trial of maximal medical therapy (3-6 wks)

At the time the case was submitted for publication Craig Hacking had no recorded disclosures. The same normal facial bones CT without labels for reference.

Each sphenoid sinus in the CT was revised to find and describe the retro-maxillary recess of the sphenoid sinus regarding its extensions and dimensions. Results This study included 100...

Paranasal sinuses have four different pairs: maxillary sinuses, frontal sinuses, sphenoidal sinuses, and ethmoidal sinuses (3). Their names come from the facial bones where they are located. Maxillary sinuses, the largest of all paranasal sinuses, have thin walls usually penetrated by the long roots of the posterior maxillary teeth (4). They ...

Background: The maxillary sinus is the largest paranasal sinus and had significant inter-individual variations. CT images are used in the assessment of the maxillary sinus. Aim: The aim of this study is to determine the prevalence, location, orientation and height of maxillary sinus

2018年12月1日 · To assess the maxillary sinus ostium (MSO) dimension and measuring the distance to nearby anatomical structures in adults using multi-slice computed tomography (MSCT). Paranasal CT scans of asymptomatic adults without paranasal sinuses or nasal pathology were included.

Maxillary sinus septae are common in atrophic maxillary sinuses (26%), and can be seen incidentally in CT scans in up to 16% of cases 3. The main nerve supply to the maxillary sinus is derived ...

CT - for bone and MRI - for soft tissue lesions. III. ANATOMY OF THE MAXILLARY SINUS. Enlarges after eruption of deciduous and again with permanent teeth. Shape - vaguely pyramidal with the base formed by the infra-temporal wall of the maxilla; the roof by the floor of the orbit.

1999年2月1日 · Axial CT scan demonstrates an opacified left maxillary sinus with thickened walls. When the lesion is superinfected, the term mucopyocele is used. Histopathologically, mucoceles and mucous retention cysts are identical.
