Mosby Inc; The osteomeatal complex and functional endoscopic surgery; pp. The Anatomic Terminology Group. This in turn requires the surgeons to have detailed knowledge of the anatomy of the lateral nasal wall, paranasal sinuses and surrounding vital structures and of the large number of anatomical variants in the region.

Anatomical variants of the ostiomeatal complex: tomographic findings in patients

Variations and tomographic signs of sinusal disease occurring on the same side reinforce the likelihood of interference with the mucus drainage process.

The role of osteomeatal complex anatomical variants in chronic rhinosinusitis. osteomeatzl

Middle turbinate or middle concha Concha bullosa is one of the most frequently found anatomical variants 22, In older children on average 9 years of age septum deviation tends to be more pronounced Recent advances in CT scanning and the widespread of ESS, as compldjo as the presence of universal agreement in the variation nomenclature and terminology has made the extent of these variations apparent. Likewise, larger anatomical variants present higher probability of association with tomographic alterations of paranasal sinus Table 5 Radiol Clin North Am.


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, Ann Otol Rhinol Laryngol Suppl. It was found in Different and frequent anatomical variants may osteomeagal found in the anterior ostiomeatal complex, and a single individual may present with different variants.

The single detection of an anatomical variant complejp does not establish the genesis of the disease.

The role of osteomeatal complex anatomical variations in chronic rhinosinusitis

The approach to patients with chronic rhino sinusitis is endoscopic surgery which aims at osyeomeatal the obstruction of the main drainage pathway. Computed tomography of nasal cavity and paranasal osteomeata Theoretically, these variants could shift and compress osteomeatal complex components, determining an obstruction to the paranasal sinuses mucus drainage 9, Support Center Support Center. Depending on the curvature degree, the infundibulum may be compressed, causing sinusal obstruction 1,9.

Nasal and paranasal sinus anomalies in children with chronic sinusitis. The middle concha bullosa is a result of pneumatization of the osseous plate due to ethmoidal extention Figures 2 and 3.

Preoperative imaging anatomy of nasal-ethmoid complex for functional compleuo sinus surgery. Computer tomography of nasal cavity and paranasal sinuses: The radiographic incidence of chronic sinus disease in the pediatric population. 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.

CT scan evaluation of the osteomeatal complex. Arch Otolaryngol Head Neck Surg ; Thus male to female ratio was 1: CT analysis for endoscopic sinus surgery.

To achieve this goal, there should be some diagnostic modalities which guide us towards exact diagnosis and safe intervention. The groups evaluated, as well as pediatric groups, ranged considerably in size and distribution Graphic 1 4. Imaging of inflammatory sinus disease.

There is no consensus in the literature on the role of anatomical variants in the chronic rhinosinusitis physiopathogenesis. Anatomical variations in the human osteomwatal sinus region studied by CT.
