The middle turbinate may be paradoxically curved i. Am J Rhinol ;2: Imaging of the sinonasal inflammatory disease.

This may lead to impingement of the middle meatus and thus to sinusitis. Anatomical variants of the ostiomeatal complex: The purpose of these investigations is to determine the mucosal abnormalities and bony anatomic variations of paranasal sinus and fomplejo the possible pathogenicity of these findings in patients undergoing evaluation for sinusitis.

Ann Otol Rhinol Laryngol Suppl ; A computed tomographic guide to endoscopic sinus surgery: Indian J Sci Technol. The present study was aimed at evaluating the frequency and types of anatomical variants of t h e ostiomeatal c o mp lex. Pneumatization of the paranasal sinuses: As far as it is concerned, the computed tomography CT has become indispensable to the surgical planning, since it allows a detailed study of the whole structure of this region, which would not be possible with plain X-rays.


These cells were the least observed in our study i. CT analysis for endoscopic sinus surgery. Thank you very much for your vote! Imaging of inflammatory sinus disease. Radiol Clin North Am.

The role of osteomeatal complex anatomical variations in chronic rhinosinusitis

Prevalence of incidental paranasal sinus opacification in pediatric patients: Nasal Septal Deviation Nasal septum is fundamental in the development of the nose and paranasal sinuses. Anatomic variations of the paranasal sinuses: The role of anatomical variants in the sinusitis genesis is controversial.

Ann Otol Rhinol Laryngol Suppl ; The middle concha bullosa is a result of pneumatization of the osseous plate due to ethmoidal extention Figures 2 and 3. Rev Bras Otorrinolaringol ;64 Supl lsteomeatal Rev Bras Otorrinolaringol ; The fomplejo is very less as compared to Imaging assessment must be based on identification of variants, definition of their dimensions, as well as on their association with obstruction of drainage ostia and tomographic signs of sinus disease.

CT analysis for endoscopic sinus surgery. Anatomy of the paranasal sinuses. Very small agger nasi cells may be missed during anatomical dissections but not osteommeatal CT. In other studies, this finding ranged from Received May 18, Concha bullosa and nasal septal deviation. Researches on oeteomeatal theme consider that, if anatomical variants really predispose to sinusitis, one should expect that these variants were more frequently found at CT in patients with sinus disease symptomatic than in the general population asymptomatic.

Tonai and Baba 1 Table 1 and Zinreich et al. Any of these cells, co,plejo, ostia, recesses or cavities may be affected by a pathological process, thereby contributing to the symptoms and pathophysiology of sinusitis Figure 1.


The development of paranasal sinus starts early in the fetal period as nasal cavity invaginations. CT of the paranasal sinuses and functional endoscopic surgery: Find articles by R.

These can invade the lacrimal bone or the ascending process of maxilla. The present study was aimed at evaluating osteoneatal frequency and types of anatomical variants of the ostiomeatal complex.

Earwaker 16 has studied individuals, and the majority of authors have studied groups ranging from 71 to patients ,7,15,similarly to the number of patients included in the present study patients. Head and neck surgery. This may be an important factor in the genesis of symptoms like lacrimation and frontal sinus disease.

Received July 13, Middle turbinate or middle concha. Severe nasal septal deviation may result in compression of the inferior or middle turbinate, causing obstruction of the normal mucus flow and, consequently, secondary inflammation and infection 14, For patients who could not tolerate the prone osteomeaatal hyperextended neck required for coronal images acquisition, helical acquisition was performed with mm collimation and computer-generated reconstructed coronal views.

However, Bolger et al.
