Which sinus is the largest?

• A. Frontal sinus
• B. Maxillary sinus
• C. Ethmoidal sinus
• D. Sphenoidal sinus

Answer: (B)

The maxillary sinus is the largest of the paranasal sinuses. Located within the maxilla, or upper jawbone, it plays an important role in the structure of the face and the overall respiratory system. Its large size allows for an effective functioning in resonance during speech and it also contributes to humidifying and filtering the air inhaled through the nasal passages. Additionally, the maxillary sinus has significant anatomical relationships with nearby structures, including the roots of the upper posterior teeth, which can be involved in dental infections that may spread to the sinus. Its size relative to the other sinuses is critical for medical professionals to understand when diagnosing and treating sinus-related conditions, such as sinusitis or complications arising from dental procedures. Understanding the spatial orientation and size of the maxillary sinus is key in both surgical practice and in resolving issues related to sinus drainage and airflow.
