A Retrospective Study of Bony Erosion Patterns in Cases of Fungal Rhinosinusitis

Abstract

ABSTRACT Erosion of bone with or without extension of disease into adjacent anatomic spaces is observed among some patients with fungal rhinosinusitis (FRS). Preoperative computed tomographies is very important to determine the sites of bony erosion. Patients with bony erosions are classified based on the involved subsite and the extent of erosion. Bony erosions was seen in 37.5% cases. Six patients were having bone erosions on CT scan. 40 % erosions were present in patients belonging to younger age group. Erosion of sinus boundaries were more common in male patients (60%). The ethmoid sinus complex was most commonly involved (46.6%). This was followed in frequency of involvement by the maxillary sinus (26.6%), the sphenoid sinus (20%) and the frontal sinus (6.6%). The most common site of erosion was the lamina papyracea (33.3%), followed by the medial maxillary wall (20%). Bony erosions due to FRS were mainly due to long-term mechanical compression by the fungal mass. A case of chronic rhinosinusitis with bony erosions in CT scan may indicate a fungal etiology.
