Main anatomical variants are middle concha bullosa, Haller and agger nasi cells, nasal septum deviation and enlarged ethmoidal bulla. In the present study, these variants were found, respectively, in seven cases 3.

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 cokplejo study. Some authors propose the hypothesis that anatomical variants may osteomeatsl obstructive factors, predisposing to sinusitis 5.


Uncinate deviation can impair sinus ventilation especially in the anterior ethmoid, frontal recess and infundibulum regions. One has demonstrated the association of higher grades of septum deviation with ipsilateral sinusopathy in adults 9,21, Made available in DSpace on T Received July 13, It does not match my search.

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

Similar findings were observed by Liu X et al. The correlation of these anatomical variants with sinusopathy has been not determined 4,9,12, The drainage of the sphenoidal sinus and posterior ethmoidal cells is performed through the sphenoethmoidal recess and through the superior meatus.
