Overview
The sphenoid sinus is located deep behind the nose, close to the optic nerves, the carotid arteries, the pituitary gland, and the base of the skull. Because of this position, problems in the sphenoid sinus can cause symptoms that are different from typical sinusitis, such as deep or back-of-the-head headache, and they sometimes affect vision or other nerves.
Sphenoid disease can result from inflammation, a fungal ball, a mucocele (a trapped, expanding pocket of mucus), or, less commonly, a tumor. Isolated sphenoid disease in particular warrants a thorough look, because symptoms can be subtle while the location is sensitive.
At Norelle Health, evaluation combines nasal endoscopy with CT and, when needed, MRI to clarify the cause. Many cases are managed medically, while endoscopic surgery is reserved for situations where it is appropriate.
Deep anatomy and why symptoms can be atypical
The sphenoid sinus sits deep in the center of the head, surrounded by the optic nerves, carotid arteries, pituitary gland, and skull base. Because it is far from the front of the face, sphenoid disease may not cause the classic facial pressure of other sinus problems. Instead it can produce headache felt deep in the head, behind the eyes, or at the top of the head.
Warning signs
Certain symptoms deserve prompt attention because of what surrounds the sphenoid sinus. These include new or worsening vision changes, double vision, severe headache, or new numbness, which can reflect pressure on nearby nerves or other complications.

Causes
Sphenoid disease can be caused by ongoing inflammation or infection, a fungal ball, a mucocele that traps and expands mucus, or, less often, a benign or malignant tumor. Isolated, one-sided sphenoid disease is one situation where imaging and sometimes biopsy are important to clarify the cause.
How it is evaluated
Evaluation usually begins with a history and nasal endoscopy. CT imaging shows the bony anatomy and the extent of disease, and MRI is added when a mucocele, tumor, or involvement of nearby structures is a concern. Together these help distinguish inflammatory disease from a mass.
Treatment options
Many cases respond to medical therapy such as saline irrigation, topical steroids, and treatment directed at the underlying cause. Endoscopic sphenoid surgery is considered when medical therapy is not enough, when a fungal ball or mucocele needs to be cleared, or when a tissue diagnosis is required. Because of the nearby nerves and vessels, surgery in this region is planned carefully and may involve skull-base coordination.

Urgent eye and neurologic symptoms
Seek emergency care for sudden vision loss, double vision, severe or rapidly worsening headache, confusion, or a stiff neck. These can indicate a complication near the sphenoid sinus that needs immediate evaluation.
