The Clinical Significance of the Uncinate Process Histopathology in Chronic Rhinosinusitis

Brief Summary:
Given that the uncinate process is the gatekeeper of the sinuses, we hypothesize that inflammation of the uncinate process is associated with decreased ventilation and drainage of the paranasal sinuses and consequently with the inflammatory process occuring in the sinuses.

Condition or disease

Detailed Description:
The purpose of the present study is to gain insight into the histopathological changes of the uncinate process in patients with chronic rhinosinusitis through comparison of its mucosal and bony elements with those of the normal uncinate process without chronic inflammation (unpublished data: Gilead Berger, Ephraim Eviatar, Tatiana Kogan, Roee Landsberg).

Time Perspective: Prospective
Official Title: New Insights on the Clinical Significance of the Uncinate Process Histopathology in Patients With Chronic Rhinosinusitis
Study Start Date : March 2010
Actual Primary Completion Date : July 2010
Estimated Study Completion Date : December 2011

Sinus drainage
Adult patients with chronic rhinosinusitis who failed treatment with antibiotics and topical corticosteroids and underwent endoscopic sinus surgery. Preoperative evaluation included paranasal sinus CT scans. The diagnosis was confirmed by endoscopic examination showing purulent and/or mucopurulent discharge in the middle and/or superior meatus.

Biospecimen Retention:   Samples Without DNA
Pathologic uncinate process tissue

Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
Patients with chronic rhinosinusitis whose uncinate process had to be removed to enable surgical access to the sinuses.

Inclusion Criteria:

Patients with chronic rhinosinusitis who:

  • Failed conservative medical treatment.
  • Stopped treatment (topical or systemic corticosteroids) at least two months before endoscopic sinus surgery.
  • Had a Lund-MacKay CT score of 2 and higher of 24 available.

Exclusion Criteria:

  • Immunosuppressed patients.
  • Patients in whom a pathologic evaluation of the middle turbinate was necessary (e.g., suspected neoplastic disorder).
  • Patients with a Lund-MacKay CT score < 2 of 24 available.
  • Pregnant women.
  • Patients who underwent prior endoscopic sinus surgery.
