I was wondering what are common complications for sinus surgery?

Uncommon. If they were common, that surgery would not be performed. That said, the risks really depend on which sinuses are treated surgically and with which surgical technique. Overall, it has become a low risk surgery. Talk to a surgeon.

Safe surgery. When done for the right reasons for chronic sinusitis, sinus surgery is 90-95% effective at reducing symptoms. Risks are low but include: scarring, anesthetic complications, bleeding, infection, recurrent disease, pain, voice changes, reduced smell, and nasal obstruction. Extremely rare complications in skilled hands include injury to the eye/brain injury, CSF spinal fluid leak, blindness, and death.
