People often consult that they have headache, nasal congestion and dry nose after nasal endoscopic surgery, is this normal? About how long does it take to relieve? We will answer them one by one below. 1.Nasal distension, headache, toothache: After the anesthesia is over, the nasal cavity will have a more intense pain for 7-8 hours. The subsequent pain is mainly related to the surgical site filling, which normally takes 24-72 hours. Patients will be extremely uncomfortable for the first 24 hours, experiencing nasal distention and headache, which will ease after 24 hours as the patient slowly adjusts. If there is a blood clot at the surgical site, it will also reduce the swelling and pain after cleaning. If the filling compresses the nerves around the nasal cavity, toothache or headache may also occur, which may slowly resolve on its own after the nasal filling is removed. If the patient still has headache after the stuffing is removed, further examination by the doctor is needed. Patients should avoid taking aspirin and non-steroidal anti-inflammatory drugs, such as painkillers and fen-phen, because these drugs have anti-coagulant effect and can aggravate nasal bleeding. 2. Bleeding: There will be some bloody secretions in the nasal cavity 3-5 days after surgery, especially after sinus rinsing. If bleeding persists after surgery, tilt your head back slightly, breathe gently through your nose, and gently wipe away the bleeding. If this does not stop the bleeding, the patient may use ephedrine nasal drops. Rest in a semi-recumbent position. If the bleeding still cannot be stopped, inform the doctor promptly. 3. Nasal congestion and runny nose: Due to postoperative swelling of the nasal mucosa, there may be nasal congestion and runny nose. Nasal ventilation and breathing will usually return to normal after 2-3 weeks after surgery. 4.Dry nose: The inner wall of the nasal cavity is originally covered with a layer of mucous membrane, and the nasal mucous membrane contains epithelial tissue, subepithelial tissue and glandular tissue. Mucosal secretions are responsible for filtering air and moistening the nasal cavity. When removing a nasal polyp, the normal mucosa is preserved as much as possible, but the diseased mucosa must be removed. The removed mucosa does not regenerate, but grows an “epithelial” layer over the wound, called epithelialization. Epithelialization is also a sign of postoperative wound healing and can reduce the occurrence of adhesions as soon as possible. However, epithelial tissue does not have the function of mucous membrane secretion, so patients may feel dry in the nose after surgery, but this situation is not rare, and with the passage of time, most patients can relieve the symptoms of dry nose. 5. Eye swelling: usually occurs during surgery or within 6 hours after surgery. Patients feel swollen eyes after nasal stuffing, some patients will also have conjunctival congestion and look red eyes, these are normal conditions, not eye complications, and will be relieved by themselves after the stuffing is removed.
