CT studies of patients evaluated for clinical suspicion of sinusopathy were analyzed. This variation can be observed either in superior, middle or inferior turbinates, although this is much more frequent in middle turbinates.

The role of osteomeatal complex anatomical variations in chronic rhinosinusitis

Accepted after revision December 14, Low dose CT in chronic sinusitis. Paranasal sinus bony anatomic variations and mucosal abnormalities: Dutra LD, Marchiori E.

Presumably these variations might induce osteomeatal obstruction, preventing mucus drainage and predisposing to chronic rhino sinusitis. Anatomic variations of osteomeatal complex and correlation with chronic sinusitis: Currently, computed tomography is the method of choice for assessment of paranasal sinuses, nasal fossae and their anatomical variants.

Anatomic variations of surgical importance in ethmoid labyrinth and sphenoid sinus. An assessment of sinonasal anatomic variants potentially associated with recurrent acute rhinosinusitis. Anatomy of the paranasal sinuses.

Late in its development, the ethmoidal sinus measures on average 36 x 18 x 14 mm length, height and width in measurements performed in MRI studies Maybe, osteoeatal divergences could be explained either by populational differences, by the definition adopted for anatomical variants Graphic 1or by the methodology of analysis 3.


Anatomic variations of the paranasal sinuses: The frequency of anatomical variants of the ostiomeatal complex is shown on Graphic 2.

The agger nasi cell is the most anterior ethmoidal cell, situated below the frontal sinus, next to the frontal recess, representing the lacrimal bone pneumatization due to ethmoidal extension Figure 6.

Frequently, agger nasi is the antero-inferior border of the frontal recess 3,24and agger nasi aeration may be implied in cases of chronic frontal sinusitis.

CT scan evaluation of the osteomeatal complex. Severino Aires de Araujo Neto et al.

Our study included 32 females and 22 males. The domplejo process is a superior extension from the lateral wall of the nasal cavity and generally is inserted into the postero-medial portion of the agger nasi 11, Hypoplastic maxillary sinus appears in about 6.

Earwaker 16in a study of cases, have described variants of the uncinate process in detail, classifying them in association with other variants of t h e ostiomeatal c o mp lex and subdividing them differently from the present study. Kainz J, Domplejo H.

Show simple item record Recommend this item. It is the epiphyseal platform for the development of the facial skeleton [ 15 ]. The exact prevalence of enlarged ethmoidal bulla is not known 9, The lateral nasal wall consists of inferior and middle turbinates and, occasionally, a superior or supreme turbinate bone with their respective meatus.


Anatomical variants of the ostiomeatal complex: tomographic findings in patients

Computed tomography of nasal cavity and paranasal sinuses: A careful analysis of consecutive CT images suggest that the osheomeatal of the uncinate process occurs because of agger nasi excavation in the most anterosuperior region of the uncinate process 3. The development of paranasal sinus starts early in the fetal period as nasal cavity invaginations. For these authors, the contact of mucosal surfaces would be more significant for the sinusitis pathogeny than the size of concha bullosa.

Introduction Chronic rhino sinusitis CRS is the most common disease for which consultation of otorhinolaryngologist is sought [ 1 ]. The unciform process pneumatization also is hardly frequent prevalence up to 2. Pneumatization of the paranasal sinuses: The wrong words are highlighted.
