What is the name of the space in the maxilla that can become infected and lead to sinusitis?

• A. Maxillary sinus
• B. Frontal sinus
• C. Ethmoid sinus
• D. Sphenoid sinus

Answer: (A)

The space in the maxilla that can become infected and lead to sinusitis is identified as the maxillary sinus. This sinus is located within the maxilla, the bone that forms the upper jaw and contains the upper teeth. The maxillary sinus is the largest of the paranasal sinuses and plays a significant role in respiratory function, including air filtration, humidification, and resonating sound. Infections in the maxillary sinus can arise from dental issues, particularly those related to maxillary molars, due to the proximity of tooth roots to the sinus. When bacteria invade the sinus, inflammation occurs, leading to symptoms associated with sinusitis, such as pain, pressure, and nasal congestion. The other sinuses, such as the frontal, ethmoid, and sphenoid, are located in different areas of the skull and are not directly related to the maxilla. While they can also become infected and lead to sinusitis, they do not specifically stem from conditions affecting the maxilla itself. Thus, when considering the link between maxillary dental health and sinus health, the maxillary sinus is explicitly the space that can become infected.
