Chronic rhinosinusitis; histopathologic study of osteitis in surgery cases. Objective: To determine whether osteitis is associated with primary and revision surgery in patients with chronic rhinosinusitis (CRS) and to determine its relationship with mucosal inflammation.

Methodology: Patients were divided into two groups based on a history of prior endoscopic sinus surgery (ESS). The primary surgery group included 74 patients who had ESS for the first time, and the revision surgery included 37 patients who had repeat ESS. Histopathological examinations were performed on specimens taken from the bony septa of the ethmoid with the overlying mucosa.

Results: The incidence of osteitis was 70.3% in patients in the revision surgery group and 56.8% in patients in the primary surgery group (p=0.229). Osteitis was associated with tissue eosinophilia and a predominance of inflammatory cells (p=0.01 and p=0.01, respectively).

Conclusions: Surgery may not be the primary cause of bone remodeling in the sinus area. Mucosal inflammation had no effect on the incidence of osteitis when it was associated with tissue eosinophilia in CRS. Patients with osteitis may benefit most from postoperative corticosteroid therapy to prevent further recurrence.
