Post Surgery Recovery

What to expect after your procedure

Immediately after FESS, patients may experience mild discomfort, congestion, and some bloody discharge from the nose. Nasal packing might be used temporarily to control bleeding and support healing, which is typically removed within 24-48 hours. Pain can be managed with prescribed medication, and rest is crucial during the initial recovery period. Over the first few weeks, it's important to avoid strenuous activities, heavy lifting, and forceful nose blowing. Regular saline nasal rinses are vital to keep the sinuses clear, prevent crusting, and promote healing. Follow-up appointments with your surgeon will be scheduled to monitor progress, remove any remaining crusts or debris, and ensure proper sinus drainage. Full recovery can take several weeks to a few months, with gradual improvement in breathing and a significant reduction in sinusitis episodes. Adhering to post-operative care instructions and maintaining good nasal hygiene are key to achieving the best long-term outcomes and enjoying lasting relief from chronic sinusitis symptoms.

Recovery & Wellness Tips

  • Consultation with an ENT specialist, including a thorough physical examination and imaging (e.g., CT scan) to map sinus anatomy.
  • Review of current medications; discontinuation of blood thinners (e.g., aspirin, ibuprofen) and certain supplements as advised by your surgeon.
  • Fasting for a specified period before surgery, typically 6-8 hours for food and drink, as per anesthesia guidelines.
  • Arranging for transportation home after the procedure, as you will be under general anesthesia and unable to drive.
  • Avoiding smoking for several weeks before surgery to optimize healing and reduce complication risks.
