Silent sinus syndrome is a spontaneous, asymptomatic collapse of an air sinus (usually the maxillary sinus and orbital floor) associated with negative sinus pressures. It can cause painless facial asymmetry, diplopia and enophthalmos. Diagnosis is suspected based on symptoms, and can be confirmed using a CT scan.
The major symptoms of ENS include a sensation of suffocation, nasal dryness, nasal burning, nasal crusting, and an impaired sense of airflow through the nose in patients who have had surgery or injury to nasal turbinates. [13] ENS can greatly reduce a patient's quality of life and many patients struggle to complete activities of daily living.
Many patients experience one or more phantom phenomena after the removal of the eye: Phantom pain in the (removed) eye (prevalence: 26%) [1] [2] Non-painful phantom sensations [1] [2] Visual hallucinations. About 30% of patients report visual hallucinations of the removed eye. [1] Most of these hallucinations consist of basic perceptions ...
The relative strength of these two forces depends on how the eye is looking. When the eye is adducted (looking toward the nose), the force of depression increases. When the eye is abducted (looking away from the nose), the force of intorsion increases, while the force of depression decreases. When the eye is in the primary position (looking ...
Typically, sinus barotrauma is preceded by an upper respiratory tract infection or allergy. The affected person has a sudden sharp facial pain or headache during descent, which increases as the aircraft approaches ground level. The pain can ultimately become disabling unless the ambient pressure is reversed.
The 51-year-old from Homewood, Alabama, was one of four patients to get stem cell transplants as part of the first U.S. study to test the technique, which could someday help thousands.
ATN pain can be described as heavy, aching, stabbing, and burning. Some patients have a constant migraine-like headache. Others may experience intense pain in one or in all three trigeminal nerve branches, affecting teeth, ears, sinuses, cheeks, forehead, upper and lower jaws, behind the eyes, and scalp.
The four paired sinuses or air cavities can be referred to as: Ethmoid sinus cavities which are located between the eyes. Frontal sinus cavities which can be found above the eyes (more in the forehead region). Maxillary sinus cavities are located on either side of the nostrils (cheekbone areas). Sphenoid sinuses that are located behind the eyes ...
