Official Title: Trial of Directed High-dose Nasal Steroids on Residual Olfactory Dysfunction in Patients With Chronic Rhinosinusitis Following Endoscopic Sinus Surgery

Brief Summary: The purpose of this study is to determine if a trial of directed high-dose nasal steroids improves residual smell loss in patients with chronic rhinosinusitis following sinus surgery. Other outcomes of this study include: identifying the differences in sinus airflow between patients who improve following nasal steroid treatment and those who do not, and to see if, in patients who improve following surgery, the improvement remains throughout follow-up.

Detailed Summary:

OVERVIEW:

This is a prospective randomized cohort study assessing the use of directed high-dose nasal steroids for improving olfactory function after endoscopic sinus surgery for chronic rhinosinusitis. Up to 70 subjects will be prospectively enrolled from patients visiting the Department of Otolaryngology-Head and Neck Surgery clinics at the University of North Carolina (UNC) Hospitals.

VISIT 1/PRE-OPERATIVE VISIT

Visit 1 will be the day of enrollment or the pre-operative visit. During this encounter, subjects will complete the Rhinosinusitis Disability Index (RSDI), Rhinosinusitis Outcome Measure 31 (RSOM-31), Sinonasal Outcome Test 22 (SNOT-22), University of Pennsylvania Smell Identification Test (UPSIT), Phenyl-ethyl-alcohol (PEA) tests and will also have their Lund-Kennedy scores recorded. Additionally, all subjects will undergo a pre-operative (standard of care) head CT which will be scored with the Lund-Mackay system. This standard of care head CT will be billed to the subject's insurance.

VISIT 2/POST-OPERATIVE VISIT(POV) 1

Visit 2 will occur at "post-operative visit 1" or 4-6 weeks after surgery. During this encounter, subjects will complete the RSDI, RSOM-31, SNOT-22, UPSIT, PEA tests and will also have their Lund-Kennedy scores recorded. Additionally, all subjects will undergo post-operative (standard of care) head CT. This standard of care head CT will be billed to the subject's insurance. Subjects who do have quantitative improvement in olfaction (as determined by UPSIT category score) will be considered part of the "improved" group and will simply be followed without an intervention. Subjects who do not have quantitative improvement in olfac

Current Primary Outcome:

  • Change in Degree of Olfactory Function [ Time Frame: 4-6 week post-operative visit ]
    Measurements of smell will be taken at the initial preoperative visit and again at the 4-6 week postoperative visit using the University of Pennsylvania Smell Identification Test (UPSIT) and the Phenyl Ethyl Alcohol (PEA) Threshold test, in which smell is assessed by smelling different concentrations of PEA. The UPSIT is a scratch and sniff test and the PEA threshold testing is a process by which the subject smells vials of different concentrations of odorant (PEA) to determine lowest detectable concentration of odorant.
  • Change in Degree of Olfactory Function [ Time Frame: 3-4 month post-operative visit ]
    Measurements of smell will be taken at the initial preoperative visit and again at the 3-4 month postoperative visit using the University of Pennsylvania Smell Identification Test (UPSIT) and the Phenyl Ethyl Alcohol (PEA) Threshold test, in which smell is assessed by smelling different concentrations of PEA. The UPSIT is a scratch and sniff test and the PEA threshold testing is a process by which the subject smells vials of different concentrations of odorant (PEA) to determine lowest detectable concentration of odorant.


Original Primary Outcome: Same as current

Current Secondary Outcome:

  • Change in Head CT Grade [ Time Frame: 4-6 week post-operative visit ]
    A head CT will be performed at the initial preoperative visit and at the 4-6 week post-operative visit. The head CT will be assessed using the Lund-Mackay scoring system, in which physician graders will analyze the CT for abnormalities in the patient's sinuses and nasal cavity.
  • Change in Head CT Grade [ Time Frame: 3-4 month post-operative visit ]
    Subjects in the "non-improved" arm (regardless of whether they were randomized to receive nasal steroids) will receive a head CT at this time point. The CT will be assessed using the Lund-Mackay scoring system, in which physician graders will analyze the CT for abnormalities in the patient's sinuses and nasal cavity.
  • Change in Nasal Endoscopy Grade [ Time Frame: 4-6 week post-operative visit ]
    Nasal endoscopy will be performed at the initial preoperative visit and again at the 4-6 week postoperative visit. The nasal cavity and sinuses will be assessed using the Lund-Kennedy scoring method which addresses crusting, scarring, edema, discharge, and presence of polyps.
  • Change in Nasal Endoscopy Grade [ Time Frame: 3-4 month post-operative visit ]
    Nasal endoscopy will be performed at the initial preoperative visit and at the 3-4 month postoperative visit. The nasal cavity and sinuses will be assessed using the Lund-Kennedy scoring method which addresses crusting, scarring, edema, discharge, and presence of polyps.
  • Change in Quality of Life [ Time Frame: 4-6 week post-operative visit ]
    Quality of life will be assessed at the initial preoperative visit as well as the 4-6 week postoperative visit using the Sinonasal Outcome Test 22(SNOT-22) and the Rhinosinusitis Outcome Measure 31 (RSOM-31). The Snot-22 and RSOM-31 are questionnaires used to measure disease related quality of life and symptoms.
  • Change in Quality of Life [ Time Frame: 3-4 month post-operative visit ]
    Quality of life will be assessed at the initial preoperative visit as well as the 3-4 month postoperative visit using the Sinonasal Outcome Test 22(SNOT-22) and the Rhinosinusitis Outcome Measure 31 (RSOM-31). The Snot-22 and RSOM-31 are questionnaires used to measure disease related quality of life and symptoms.
  • Number of patients with steroid side effects after a 1-2 week course of steroids [ Time Frame: 5-8 weeks post-operatively ]
    Subjects who were randomized to the treatment arm will be contacted by phone 1-2 weeks after starting steroids and will review a pre-constructed medication safety and side effect questionnaire with the caller. Patients will also be asked to review their medication diary with the caller.
  • Number of patients with steroid side effects after a 8 week course of steroids [ Time Frame: 3-4 month post-operative visit ]
    Subjects who were randomized to the treatment arm will return to clinic 3-4 months postoperatively and medication diaries will be reviewed and assessed for compliance and concerning side effects. These diaries will be collected for future review by the independent data safety reviewer.
