Brief summary

The objective of this study is to determine whether the use of postoperative antibiotics following endoscopic sinus surgery (ESS) decreases postoperative infection rates. This is a multi-institutional prospective study involving Albert Einstein College of Medicine/Montefiore Medical Center, Columbia University Medical Center, Weill Cornell Medical College, Mount Sinai Health System, and New York University Langone Medical Center. The study design will be a multi-institutional prospective randomized controlled trial with parallel random groups assigned to receive postoperative antibiotics or no postoperative antibiotics. The investigators hypothesize that patients who receive postoperative antibiotics will have lower postoperative infection rates and improved postoperative sinonasal symptoms and nasal endoscopy scores.

Inclusion criteria

* Patients with Chronic Rhinosinusitis (CRS) with or without nasal polyposis or allergic fungal rhinosinusitis who present to the otolaryngology clinic who have been deemed suitable for bilateral ESS, and are over the age of 18 will be included.

Exclusion criteria

* Patients with sinonasal tumors, allergies or adverse reactions to all of the antibiotics that will be used in this study (amoxicillin-clavulanate, doxycycline, clarithromycin), immunodeficiency, cystic fibrosis, pregnancy, or diabetes with nasal polyposis (inability to receive systemic steroids) will be excluded, as will patients who lack capacity to provide informed consent. Patients undergoing active treatment for malignancy will be excluded. Patients undergoing unilateral ESS or with nonabsorbable packing placed at the time of surgery will be excluded. Patients who have been on antibiotics within 2 weeks of the surgery date will be excluded. Patients with acute on chronic sinusitis or the presence of purulence at time of surgery will be excluded from the study.

Design outcomes

Primary

MeasureTime frameDescription
Postoperative InfectionDuring all three scheduled postoperative visits: 7-10 days postoperatively; 2-4 weeks postoperatively; 6-8 weeks postoperativelyThe number/percentage of participants with postoperative infection rate, as assessed by rigid nasal endoscopy in the office and culture of suspected infectious material noted within the paranasal sinuses will be reported. A postoperative infection as defined by having an infection at ANY of the postoperative visits AND detected initially by evidence of purulence on nasal endoscopy will be considered an infection if the culture swab from the site of purulence during that office visit confirms that there is an actual bacterial source of the infection.

Secondary

MeasureTime frameDescription
Postoperative Sino-nasal Outcome Test (SNOT-22) ScoresDuring all three scheduled postoperative visits: 7-10 days postoperatively; 2-4 weeks postoperatively; 6-8 weeks postoperativelyPostoperative SNOT-22 scores will be summarized for each visit based on patient-reported symptoms. The SNOT-22 is a 22-item questionnaire used to assess the impact of chronic rhinosinusitis (CRS) on a patient's health-related quality of life. Participants are presented with a list of symptoms and social/emotional consequences of rhinosinusitis and asked to rate each problem over the prior 2-week period on a 6-point Likert scale ranging from 0 (No Problem) to 5 (Problem as bad as it can be) yielding an overall possible scoring range of 0-110. Higher scores are indicative of a greater burden CRS-related symptoms. Scores are summarized by study arm using basic descriptive statistics.
Perioperative Sinus Endoscopy (POSE) ScoresDuring all three scheduled postoperative visits: 7-10 days postoperatively; 2-4 weeks postoperatively; 6-8 weeks postoperativelySinonasal crusting and inflammation was determined using the perioperative sinus endoscopy (POSE) scoring system based on patient-reported symptoms obtained during all three study visits. POSE assigns points to various areas within the nasal passages, based on the presence of certain conditions like crusting, edema, polyps, secretions, etc. For purposes of this study each parameter was scored from 0-2 yielding an overall possible score of 0-10, with higher scores being indicative of more extensive disease severity or surgical extent in the sinuses. Scores are summarized by study arm using basic descriptive statistics.

Postoperative Infection

The number/percentage of participants with postoperative infection rate, as assessed by rigid nasal endoscopy in the office and culture of suspected infectious material noted within the paranasal sinuses will be reported. A postoperative infection as defined by having an infection at ANY of the postoperative visits AND detected initially by evidence of purulence on nasal endoscopy will be considered an infection if the culture swab from the site of purulence during that office visit confirms that there is an actual bacterial source of the infection.

Time frame: During all three scheduled postoperative visits: 7-10 days postoperatively; 2-4 weeks postoperatively; 6-8 weeks postoperatively
