The Factors Related to the Time for Sinus Debridement after Functional Endoscopic Sinus Surgery - A Retrospective...

Post-operative care after functional endoscopic sinus surgery (FESS) is essential for managing the long-term success of chronic rhinosinusitis. Post-operative sinus debridement promotes proper wound healing, but the procedure can be accompanied by discomfort and pain. Hence, we analysed the clinical factors related to sinus debridement time after FESS.

We evaluated retrospectively the clinical factors affecting the time taken for post-operative sinus debridement on the first visit after the discharge. We reviewed 101 patients who underwent FESS at our hospital by the same surgeon and extracted patient information. The time for post-operative sinus debridement at the first outpatient clinic was measured.

The days of putting the cotton ball in the operated nostril were negatively associated with sinus debridement time (coefficient - -16.4 ± 5.7 seconds/day, P = 0.005). In contrast, current or history of asthma, amount of bleeding during the surgery, number of opened sinuses by the operation or the number of eosinophils in resected tissues under a microscope at ×400 was not associated.

We recommend the use of a cotton ball in the nostril after FESS because it shortens the sinus debridement time. Placing cotton balls in the nostril helps to maintain a humid wound environment and reduce crusting, leading to easier sinus debridement and better wound healing.
