A sinus, specifically the maxillary sinus (also known as the antrum of Highmore), is an air-filled space within a bone; in this case, the maxillary sinus is located within the maxillary bone.
Understanding the Maxillary Sinus/Antrum of Highmore
The maxillary sinus, or antrum of Highmore, is the largest and first to develop of the paranasal sinuses. It's crucial to understand its location and relationship to surrounding structures.
Location and Boundaries
- Location: Found within the body of the maxillary bone.
- Inferior Boundary: The alveolar process of the maxilla. This area supports the teeth (dentition).
Function (Although not directly stated in reference)
While the reference does not detail function, generally paranasal sinuses contribute to:
- Reducing the weight of the skull.
- Humidifying inhaled air.
- Resonating the voice.
Significance
The maxillary sinus is clinically important for several reasons:
- Sinusitis: It can become infected and inflamed, leading to sinusitis.
- Dental Issues: Because of its proximity to the teeth, dental infections can sometimes spread to the sinus.
- Surgical Considerations: Dental implants or extractions in the upper jaw require careful consideration of the sinus location to avoid complications.
