Brief Summary:
Functional endoscopic sinus surgery (FESS) is the gold standard surgical intervention for management of patients with chronic rhinosinusitis (CRS). Synechiae formation in the middle meatus is the most common complication of endoscopic sinus surgery after FESS. Nasal debridement is a postoperative procedure used in the prevention of synechiae formation. This procedure lacks standardized evidence-based guidelines. The currently existing studies that have been conducted to determine the efficacy of post-operative debridement have shown conflicting results. We hypothesize that there is no difference in short and long term clinical outcomes between patients who had routine post-operative nasal debridement following FESS and patients who did not have post-operative nasal debridement.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 150 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description:

There will be two possible scenarios resulting from randomization:

  1. The patient is randomized to the arm that receives routine post-operative debridement (treatment group).
  2. The patient is randomized to the arm that will not receive post-operative debridement (control group).
Masking: Single (Investigator)
Masking Description: The patient will know if he/she is getting debridement or not. The PI will comment on all the objective outcome measures and will be the blinded assessor (he will not perform the debridements).
Primary Purpose: Treatment
Official Title: The Efficacy of Debridement of the Sinus Cavity Following Primary Functional Endoscopic Sinus Surgery (FESS): A Randomized Controlled Trial.
Actual Study Start Date : June 22, 2018
Estimated Primary Completion Date : July 1, 2021
Estimated Study Completion Date : September 1, 2021

Arm Intervention/treatment
Experimental: Debridement group
Patients receive routine post-operative debridement at their Day 6, 30 and 60 follow up appointments.
Procedure: Debridement
Debridement or cleaning of the sinuses post-operatively has been described as a regular post-surgery procedure .

No Intervention: Non Debridement Group
Patients will not receive debridement at any follow up visit after surgery. They will continue with saline irrigation.

Primary Outcome Measures :
  1. Change in Postoperative Synechiae [ Time Frame: Day 30, 60, 90, and 180 follow-up visits. ]
    The existence of postoperative synechiae will be considered as a categorical, dichotomous outcome variable (presence or absence).

Secondary Outcome Measures :
  1. Sinonasal Outcomes Test - 22 (SNOT-22) [ Time Frame: Day 30, 60, 90, and 180 follow-up visits. ]

    The SNOT-22 is a sinus-specific questionnaire that evaluates subjective symptoms for patients suffering from chronic rhinosinusitis.

    SNOT-22 is scored out of 110 (22 questions, up to 5-points each) has demonstrated internal consistency, reliability, discriminate and concurrent validity and responsiveness to change. Responses will be summated and considered as a continuous, numerical variable.

  2. Philpott-Javer (PJ) and Modified Lund-Kennedy (MLK) Endoscopic Staging System (ESS) [ Time Frame: Day 30, 60, 90, and 180 follow-up visits. ]
    Sinonasal mucosal inflammation is an objective measure assessed endoscopically and graded on both the PJ and MLK ESS for CRS.

  3. Visual Analog Score (VAS) for pain and discomfort [ Time Frame: Day 6, 30, 60, 90, and 180 follow-up visits. ]
    The visual analog score describes subjective pain and discomfort levels experienced by the participant following the procedures in both arms of the study.
