Sinusitis surgery does not usually leave sequelae, but fungal sinusitis surgery is similar to ordinary sinusitis surgery, and there is a risk of surgery-related complications, such as nasal bleeding, intracranial complications, and orbital complications. 1. Nasal hemorrhage: If there is an intraoperative pterygopalatine artery injury or anterior sieve artery injury there may be a risk of postoperative hemorrhage. 2. Intracranial complications: after surgery for fungal sinusitis, patients may develop intracranial hematoma, cerebrospinal fluid rhinorrhea, intracranial meningitis, cavernous sinus thrombophlebitis and other related intracranial complications. 3. Orbital complications: If the surgery leads to damage to the extraocular muscles or the orbital wall, it may lead to limitation of the patient’s eye movement and damage to the optic nerve, which may cause the patient to suffer from blindness, diplopia and other related conditions. The above sequelae are theoretically possible, as long as you choose a regular hospital, timely surgery, relatively speaking, the sequelae of fungal sinusitis surgery is relatively small.
