Objective:
The blocking of airflow into sinonasal cavity may decrease postoperative crusting and the development of adhesions. The purpose of this study was to investigate the efficacy of cotton ball packing in patients following endoscopic sinus surgery (ESS).
Methods:
Thirty nine patients with chronic rhinosinusitis requiring the same extent of ESS were included. As a part of postoperative care, the patients were instructed to perform a nasal saline irrigation and apply a nasal spray in each nostril, and then informed to put a cotton ball in a one side of nostril, and the other side was kept to be empty as a control. Patients' subjective symptoms, patients' pain while receiving sinonasal cavity debridement, time required to perform debridement, and postoperative wound healing were evaluated.
Results:
Although cotton ball packing resulted in less discomfort for postnasal drip, rhinorrhea, headache, and facial pain than no packing, there were no statistically significant differences between the groups. The cotton ball packing was associated with significantly less pain on while performing postoperative debridement, therefore less time was needed to perform debridement. The cotton ball packing appears to improve wound healing within the sinus cavities up to 1 month postoperatively.
Conclusion:
The use of the cotton ball packing after ESS results in significantly less formation of crusts and adhesions, leading to decreasing pain and time during postoperative debridement and promoting faster wound healing.
