Abstract
Eustachian tube connects middle ear space to the nasopharyngeal space. Upper airway obstruction, with any cause, can derange Eustachian tube function. Nasal septal deviation is one of the prevalent causes of upper airway obstruction which can affects the ventilation function of Eustachian tube.
Materials and Methods: This study was conducted on the patients who underwent septoplasty due to severe septal deviation leading to unilateral nasal obstruction in Amiraalam hospital from summer of 1378 till the spring of 1379.
Results: There was 140 patients whose data were as: female patients 34 (24.3%) male patients 106 (75.7%), mean age (22.7). Median age (20) years and mode of age (18) years of age. they were from 12 to 40 years of age.
Conclusion: Comparison between preoperative and postoperative middle ear pressures shows no any significant statistical difference (p=0.798).

Abstract
Background: Imaging abnormalities in the paranasal sinuses are regularly noted as incidental findings on MRI, however, little is known about their prevalence in the Iranian population. The purpose of this study was to classify these findings in the paranasal sinuses as seen on MRI and to investigate the prevalence, according to site and type of paranasal abnormality.
Methods: In this cross-sectional study, the T2-weighted axial MRI of 256 patients with diseases unrelated to their paranasal sinuses were reviewed between May 2002 and June 2003. The findings were categorized according to the anatomic location and the imaging characteristics of the abnormality. The abnormalities recorded included total sinus opacification, mucoperiosteal thickening >5mm, air fluid levels and retention cysts or polyps. Unilateral or bilateral involvement and septal deviation were also noted. A sinus was considered normal if it was fully aerated and no soft-tissue density was apparent within the cavity.
Results: Among our cases, 111 (43.5%) were male and 145 (56.5%) were female. Of these patients, abnormalities in one or more of the sinus groups were found in 110 subjects (42.9%), 55.5% of which were male and 44.5% were female (P=0.001). Maxillary sinus abnormalities were observed in 66.4% of the patients, while ethmoid sinus abnormalities were found in 63.6%. Of the ethmoid abnormalities, 21% were found in the anterior section, 9% in the middle ethmoid, and 8% in the posterior ethmoid. The most common abnormality found was mucosal thickening. Among our cases, 23.4% had septal deviation, which was significantly higher among those with sinusitis (29% versus 19.1% P<0.01).
Of those patients with sinus involvement, 16% were involved in the sphenoid sinus and 5% in the frontal sinus. The results obtained from the patients with sinus abnormality revealed that 85% suffered from cough, nasal obstruction, runny nose, facial pain and post nasal discharge and 24% had been diagnosed with chronic sinusitis by physician.
Conclusion: Our results showed that there was a high rate of incidental abnormalities in the paranasal sinuses that are unrelated to the patient's presenting problems.
