People often ask about headaches, nasal congestion, and dry nose after their nasal endoscopy procedure, is this normal? How long does it take to relieve? Here we will answer one by one. ① Nasal distension, headache, toothache: After the anesthesia has worn off, the nasal cavity will have a more intense pain for 7~8 hours. The pain that follows is mainly related to the surgical site filling, which normally takes 24 to 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 discharge in the nasal cavity 3 to 5 days after surgery, especially after sinus rinsing. If postoperative bleeding persists, 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. (Semi-recumbent position) 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. ④Dry nose: The lining of the nasal cavity is originally covered with a mucous membrane, which contains epithelial and subepithelial tissues as well as glandular tissues. Mucosal secretions are responsible for filtering the 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 dryness in the nose after surgery, but this is not common, and most patients’ dry nose symptoms can be relieved with the passage of time. ⑤ Eye swelling: usually occurs during surgery or within 6 hours after surgery. Patients may feel swollen eyes after nasal stuffing, and some patients may also have conjunctival congestion and red-looking eyes, which are normal and not an eye complication and will resolve on their own after the stuffing is removed.
