One of the main concerns about using packing is that the removal is usually very painful and can be very bothersome. This procedure may even result in syncope by the activation of the vasovagal reflex system.

Many patients who have undergone nasal surgery report that the removal of the pack was the most painful part of the experience.

Postoperative pain is an acute inflammatory pain that starts with surgical trauma and ends with tissue healing. It can be harmful to organ systems by initiating inflamma¬tion through different mechanisms, and the alleviation of postoperative pain is considered important for obtaining homeostasis. Pain may initiate atelectasis due to improper coughing, immobilization may cause thromboembolism and catecholamine discharge may induce cardiovascular side effects and undesired changes in neuroendocrine or meta¬bolic function
