Anatomy of the paranasal sinuses. Sinusopathy is a common clinical problem that, sometimes, does not present an adequate response to medicamentous therapy.

It may determine compression of the middle concha with consequential infundibulum obstruction 9. This may lead to impingement of the middle meatus and thus to sinusitis.

Some authors 1,4 do not mention this anatomical variant in their studies. Computerized tomography in the evaluation of anatomic variations of the ostiomeatal complex. Find articles by Saurabh Kumar. Other pneumatized structures were: Prevalence of multiple anatomical variations was more in our study osteomeatzl comparison to single anatomical variation.

Local anatomic variations including concha bullosa, deviated nasal septum DNSHaller cells, paradoxical middle turbinates, agger nasi cells and many others may be the source of middle meatal obstruction and subsequent rhino sinusitis. In cases where the curvature unusually occurs toward the opposite side, they are called paradoxical turbinates 14, Tonai A, Baba S.

Variations of osteomeatal complex and its applied anatomy: The first most anterior portion of the complex includes structures surrounding the frontal recess; the second one corresponds to the structures including the maxillary sinus and middle meatus; and the third and most posterior portion includes the structures surrounding the sphenoethmoidal recess.

Anatomical variations in the human paranasal sinus region studied by CT. The single detection of an anatomical variant itself does not establish the genesis of the disease. Received July 13, Dutra LD, Marchiori E. Lower prevalences are found in the study including lower age ranges 1 to 7 years of age 6.

The prevalence of anatomical variants seems to increase with the age Table 4. Anatomical variations in the human paranasal sinus region studied by CT. In the present study, these variants were found, respectively, in seven cases 3.

In the present study, the Zinreich et osteomeatl. Anatomic variants in sinonasal CT.

Its prevalence in children ranges from CT examination for endoscopic sinus surgery. In the present study, the most frequent variants were those involving the middle turbinates, particularly their pneumatization and paradoxical curvature, deviation of the nasal septum and pneumatized agger nasi cells, infraorbital ethmoid cells and uncinate process.


Again, the size of the ethmoidal bulla has not been described separately. Radiol Clin North Am. Surgical clearance of these chronically infected sinuses while maintaining their ventilation and drainage is the treatment of choice [ 6 ].

Some studies on the prevalence of anatomical variants have failed in identifying a significant relation with rhinosinusitis symptoms or with mucosal alterations of paranasal sinus at CT 1,4,19, Coronal CT scan abnormalities in children with chronic sinusitis. 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.

The association of anterior ethmoidal cells and maxillary sinuses with tomographic alterations may depend not only on the subtype, but also on dimensions of the concha bullosa
