Maxillary Sinus Fungal Infection as a Possible Cause of Ptosis
This case report describes a rare instance of maxillary sinus fungal infection causing ptosis and diplopia in a 73-year-old female, highlighting the importance of considering this etiology in atypical ocular presentations through imaging and pathological confirmation.

Imagine your body as a house with many rooms. The maxillary sinus is like a small, hidden storage closet located just behind your cheekbone. Usually, this closet is empty and clean. But in this story, a 73-year-old woman's "cheekbone closet" got invaded by a tiny, unwanted tenant: fungus.
Here is the story of how a problem in that hidden closet caused a very visible problem with her eye, explained simply.
The Mystery Symptom: The Drooping Eye
The woman went to the eye doctor because her right eyelid was slowly drooping (a condition called ptosis) and she was seeing double (diplopia). It had been getting worse for two months.
Usually, when an eye droops, doctors think the problem is inside the eye or the brain's wiring. They checked her eye, her brain scans, and her blood, but everything looked normal. It was like checking the lightbulb and the switch in a room, but the problem was actually a clogged pipe in the wall behind it.
The Hidden Culprit: The Fungal "Fungus Ball"
The doctors then looked at her nose and sinuses with a special camera (CT scan). They found that her right cheekbone sinus was filled with a messy mix of thick gunk and hard spots.
Think of this like a moldy fruit sitting in a sealed jar. Over time, the fungus grew into a solid "ball" (medically called a fungus ball).
- The Good News: This wasn't an aggressive, eating infection. It wasn't chewing through the walls of the closet (bone) or spreading wildly. It was just a localized, non-invasive clump of fungus.
- The Bad News: Even though it wasn't "eating" the walls, it was still causing trouble.
The Connection: How a Cheek Infection Affects an Eye
This is the tricky part. The maxillary sinus (cheek) is usually far away from the eye muscles that lift the eyelid. It's like having a leak in the basement affecting the light switch on the second floor.
The paper suggests a few ways this might happen:
- The Detour: The fungus might have traveled from the cheek sinus, up through the middle of the nose, and into the ethmoid sinuses (the sinuses right next to the eye).
- The Pressure Cooker: Once the fungus got close to the eye, the inflammation or pressure might have irritated the tiny nerves that tell the eyelid to stay open.
It's rare for a non-aggressive fungus ball to cause eye symptoms. Usually, only the "aggressive" kind that eats through bone causes eye problems. This case was a unique puzzle because the "gentle" fungus ball still managed to mess with the eye nerves.
The Patient's Background: Why Did This Happen?
The paper notes that this woman had a few things that made her "house" more vulnerable to fungal tenants:
- Age: She was 73.
- Diabetes: High blood sugar can weaken the body's security system (immune system), making it harder to fight off invaders.
- Antibiotics: She had taken antibiotics for her nose in the past. Think of antibiotics as a "weed killer" that wipes out the good bacteria. When the good bacteria are gone, the "weeds" (fungus) can grow unchecked.
The Solution: Cleaning the Closet
The doctors didn't need to use strong antifungal drugs (which can be hard on the liver and kidneys). Instead, they performed a minimally invasive surgery.
Imagine a plumber using a tiny camera and tools to go through the natural doorway of the sinus, rather than breaking a hole in the wall. They:
- Sucked out the fungal "ball" and gunk.
- Made sure the "door" to the closet was wide open so air could flow and it wouldn't get clogged again.
The Result
After the surgery, the woman went back to the eye doctor. The "pressure" or irritation on the nerve was gone. Slowly, her eyelid stopped drooping, and her vision returned to normal.
The Big Lesson
The main takeaway from this paper is a warning for doctors (and a lesson for us): Don't just look at the symptom; look at the whole house.
If an elderly patient with diabetes or a history of antibiotic use comes in with a drooping eyelid, doctors shouldn't just assume it's a nerve problem in the brain. They should also check the sinuses. Sometimes, a hidden fungal infection in the cheek can be the real reason the eye is acting up. By finding the root cause (the fungus ball) and cleaning it out, the eye problem fixes itself without needing heavy medication.
