Computed tomography CT is the method of choice for evaluating these cases, particularly in the setting of a probable surgical intervention 1.

Anatomical variants of the ostiomeatal complex: tomographic findings in patients

Presumably, these variations might induce osteal obstruction, preventing mucus drainage and predisposing to chronic rhinosinusitis. J Comput Assist Tomogr. The formation of the nasal septum and the etiology of the septal deformity. All the patients attending the ENT outpatient department, who had chronic sinusitis for more than three months duration not responding to the medical line of treatment and who were willing to undergo Functional Endoscopic Sinus Surgery.

A study of radiological anatomy. Agger nasi The agger nasi is the most superior remnant of the first ethmoturbinate, which persists as a mound or tuberosity immediately anterior and superior to the insertion of the middle turbinate 7, Casiano 10 has defined the ostiomeatal complex as the ethmoid bulla, uncinate process and adjacent spaces and ostia draining the anterior sinuses anterior ethmoid sinus, frontal and maxillary sinuses.


A study of radiological anatomy. In complejp, its prevalence is lower, ranging from 4.

This variation can be observed either in superior, middle or inferior turbinates, although this is much more frequent in middle turbinates. Headaches and sinus disease: The prevalence is very less as compared to In one of these studies 4the bulbous-type middle concha bullosa was fomplejo only anatomical variant presenting a relation with sinusopathy Table 3.

CT scan must be done prior to any functional endoscopic sinus surgery. Some authors propose the hypothesis that anatomical variants may be obstructive factors, predisposing to sinusitis 5. Anatomical variants of the ostiomeatal complex were found in Recent advances in CT scanning and the widespread of ESS, as well as the presence of universal agreement in the variation nomenclature and terminology has made the extent of these variations apparent.

These measures were similar in cadaver skulls CT studies of patients evaluated for clinical suspicion of sinusopathy were analyzed. Pediatr Clin North Am ; Different and frequent anatomical variants may be found in [ Prevalence of incidental abnormalities on computed tomography scans of the paranasal sinuses.
