“…The osteomeatal complex would be formed by the two first portions 11 . Mafee et al 12 and Mafee 13 have described the osteomeatal complex similarly to the definition by Zinreich et al 11 . Laine & Smoker 14 have defined the osteomeatal complex as an aerated channel of the middle meatus representing the final common pathway for drainage of the maxillary and frontal sinuses and anterior ethmoid cells, delimited by the uncinate process, ethmoidal bulla and middle turbinate.…”

OBJECTIVES:To study the various anatomical variations of the osteomeatal complex and their incidence in patients with chronic rhinosinusitis. DESIGN: A prospective study was done on 100 computed tomography scans of patients with chronic rhinosinusitis. RESULTS: Various types of anatomical variations were observed in the study viz. concha bullosa, septal deviation, paradoxical middle turbinate, retroverted uncinate process, enlarged ethmoid bulla, haller cells, agger nasi cells, onodi cells and pneumatization of vomer. The most frequent anatomical variation found was septal deviation (30%), followed by presence of concha bullosa (26%). CONCLUSION: Variations are common in the osteomeatal complex. These variations may predispose to sinusal diseases and hence require correction. Also, preoperative detection of such variations by computed tomography avoids complications during functional endoscopic sinus surgery.

“…In practice, interviews concerning the causal relation, frequency, latent period and atopic disposition often provide suggestions but sometimes give unreliable evidence to base the diagnosis of occupational nasal allergy. Therefore, nasal provocation tests (144,(1314)(1315)(1316)(1317) are necessary to confirm the causality between the disease and any work exposure (1390 Computerized tomography has become the principal radiological investigation for major sinonasal disorders but is of limited use in the diagnosis of allergic rhinitis (1392)(1393)(1394)(1395)(1396). Computerized tomography scans can be carried out after receiving specialist advice:…”

“…Many researchers warn of possible serious surgical complications to the optic nerve when Onodi cells and the posterior ethmoid sinuses are involved [8,[10][11][12], and optic nerve damage secondary to sinus surgery has been reported [13][14][15][16][17]. However, a lesion of an Onodi cell has not been documented to cause optic neuropathy, despite Ogata/Okinaka/Takahashi endoscopic and radiologic findings that emphasize the vulnerability of the optic nerve.…”

A rare case of retrobulbar optic neuropathy caused by an isolated mucocele in an Onodi cell is presented. A 63-year-old man suffering from left recurrent optic neuropathy had shown improved visual acuity with steroid treatment at the age of 48 and 56 years. Impaired visual acuity and blurred vision in the left eye appeared again, and a marked inferior decrease in the left visual field was noted. Although axial computed tomography (CT) showed no abnormal findings, magnetic resonance imaging (MRI) revealed a small squamous-shaped lesion (17 × 17 × 7.3 mm) in the left posterior ethmoidal air cell (Onodi cell) hanging over the left optic nerve. Endoscopic sinus surgery was performed. The optic canal was extruding into the Onodi cell cavity, and the superior bony wall of the canal was eroded by the mucocele. The isolated mucocele in the Onodi cell seemed to be compressing the optic nerve downward and causing retrobulbar optic neuropathy. An Onodi cell lesion, even if it was isolated and small, would cause optic neuropathy. MRI and coronal CT scanning should be performed for the diagnosis and preoperative planning in a case of retrobulbar optic neuropathy.
