It is important to note that no surgery is successful in 100% of cases. All surgeries have the potential for complications. With endoscopic sinus surgery, as with most surgeries, serious complications are uncommon. Most complications are not serious and are easily treated with antibiotics or other simple measures.
Any complications from endoscopic sinus surgery are the same as with any type of sinus surgery. While complications are infrequent with all sinus surgeries, there are fewer incidents with endoscopic sinus surgery than the more invasive traditional surgeries.
The most common serious complication, which occurs in approximately 2% of cases, is leakage of the body's spinal fluid. This is usually discovered during the surgery itself and repaired at that time so that no adverse effects will occur.
The worst and most rare complication is blindness, which is caused by damage to the optic nerve in the eye.
