Where is the frontal sinus located?

1. Above the molars

2. In the mandible

3. In the frontal bone above each eye

4. At the back of the throat

The correct answer is: In the frontal bone above each eye

The frontal sinus is located in the frontal bone, which is situated above each eye. This sinus is one of the four pairs of paranasal sinuses and plays a role in various functions, including lightening the weight of the skull and producing mucus. Its position allows it to drain into the nasal cavity, which is significant for maintaining respiratory health and drainage of mucus. The anatomical placement of the frontal sinus also allows it to be involved in resonance during speech. Understanding the correct location of the frontal sinus is crucial for dental and medical professionals, as issues such as sinusitis can affect dental health and procedures.
