Because intraoperative vasoconstrictive drugs and careful hemostasis are not used, the chance of postoperative bleeding is minimal. There is a small amount of bleeding for 3 days after surgery, especially when waking up in the morning or after sitting up after a long period of bed rest, usually due to blood that has accumulated in the saddle area of the pterygoid sinus during surgery. If there is a lot of bleeding a hospital visit for nasal endoscopy is required.
It is also normal if there is a small amount of fluid leakage after surgery, which can usually disappear on its own within 1 day or a few days. If you experience a large amount of fluid flow that cannot be stopped, you need to consider cerebrospinal fluid leakage. In particular, a large amount of fluid flow that cannot be stopped, which is more pronounced when the head is tilted forward in a sitting position, must be considered immediately for cerebrospinal fluid leak repair to avoid encephalitis. If the cerebrospinal fluid leak occurs in the saddle node surgery is the worst because the filled fat can compress the optic nerve on both sides and the posterior optic cross. Repair of cerebrospinal fluid leaks in the olfactory groove and slope is relatively easy.
