Cerebrospinal fluid is not found in the frontal sinus. The frontal sinus is an air-filled cavity within the frontal bone of the skull, while cerebrospinal fluid is a clear fluid that surrounds the brain and spinal cord within the subarachnoid space.
The dural venous sinus that contains arachnoid granulations is superior saggital sinus.
The arachnoid granulations located in the superior sagittal sinus are responsible for absorbing cerebrospinal fluid from the subarachnoid space back into the bloodstream. This process regulates the fluid volume in the brain and helps maintain intracranial pressure.

Mucosal thickening in the right maxillary sinus is a common finding on a sinus CT scan and can indicate inflammation or infection. This thickening may be due to conditions such as sinusitis, allergies, or a viral infection. Further evaluation by a healthcare provider may be needed to determine the underlying cause and appropriate treatment.
paranasal sinus include frontal sinus, the maxillary sinus, the ethmodial sinuses, and the spheniodal sinus.
One way to treat sinus drainage is to keep mucus thin rather than thick. Another way is to clean the nasal by flooding with fluid and this is a quick method to unclog the nose.
Pregnancy and fluid in the ears are unrelated to the best of my knowledge. The fluid is caused by a build up in the sinuses, after a cold or sinus allergy. It can cause dizziness, pain and infection if it does not drain on it's own.
Clear fluid coming out of your nose could be a sign of allergies, a cold, or sinus congestion. It could also indicate a cerebrospinal fluid leak, which would require medical attention. If you suspect a cerebrospinal fluid leak, seek immediate medical help.
The ear canal and sinus are connected through a small passage called the Eustachian tube. Issues in the sinus, such as inflammation or congestion, can lead to blockage of the Eustachian tube. This can cause pressure changes in the ear, leading to symptoms like ear pain, hearing loss, and even infections. Similarly, problems in the ear, such as infections or fluid buildup, can also affect the sinus and lead to sinus issues like congestion or sinusitis.
