After surgery for fungal pteroid sinusitis, there are usually no sequelae, and there may be surgical complications, such as nasal discomfort, intracranial complications, and eye diseases. 1. Nasal discomfort: large intraoperative trauma, postoperative medication or review, if not regular, may cause intranasal adhesion, nasal dryness, nasal bleeding, intranasal soreness and swelling. 2. Intracranial complications: the pterygoid sinus is close to the base of the skull, which may cause dural hemorrhage, cerebrospinal fluid leakage, intracranial infection and other sequelae during the operation. 3. Ocular diseases: the operation affects the orbital area, which may cause periorbital bruising and hematoma, resulting in limited eye movement, vision loss, and in severe cases, blindness, and so on. Not all of the above complications occur after fungal pteroid sinusitis surgery. After surgery, you should follow the doctor’s instruction to follow up on time, and if any abnormality occurs, communicate with the surgeon in time to deal with it accordingly.
