The maxillary antrum, also known as the maxillary sinus or antrum of Highmore, is the largest and first to develop of the paranasal sinuses.
Understanding the Maxillary Antrum
Here's a breakdown:
-
Location: The maxillary antrum lies within the body of the maxillary bone.
-
Function: It is one of the paranasal sinuses, contributing to the humidification and filtration of inspired air.
-
Inferior Boundary: The alveolar process of the maxilla, which supports the teeth, forms the inferior boundary of the sinus. This proximity to the teeth can sometimes lead to dental issues affecting the sinus and vice versa.
-
Development: Notably, it's the first paranasal sinus to develop.
Maxillary Sinus: Key Features in Table Format
| Feature | Description |
|---|---|
| Alternative Name | Antrum of Highmore, Maxillary Sinus |
| Location | Within the maxillary bone |
| Size | Largest of the paranasal sinuses |
| Development | First paranasal sinus to develop |
| Inferior Border | Alveolar process of the maxilla (supports teeth) |
| Significance | Contributes to humidification/filtration of air; close proximity to teeth can lead to dental-related sinus issues |
