They all had perennial allergic rhinitis, 50.7% of them had atopy, 47.8%, asthma as an added disease, 27.5%, nasal polyposis and 44.9%, sinusitis, in maxillary sinus 59.9%, in ethmoid 36.2% in 7.2% frontal. With septal deviation 33.3%, in 7.2% septal deviation with spur, obstruction of the osteomeatal complex in 4.3%, turbinate hypertrophy in 53.5%, polyps in 27.5% and bullous conchae in 7.2%. The diagnosis was performed by axial computerized tomography of paranasal sinuses.
