Occult sinus abnormalities in the asthmatic patient.

Area of Science:

• Otolaryngology
• Pulmonology
• Allergy Immunology

Background:

• Unrecognized sinusitis is a significant factor in patients with asthma, chronic rhinitis, and urticaria.
• The clinical presentation of sinusitis can be subtle and often overlooked.
• The relationship between sinusitis and exacerbations of allergic and respiratory conditions requires further investigation.

Purpose of the Study:

• To examine the utility of roentgenography of the paranasal sinuses in patients with asthma, chronic rhinitis, and urticaria.
• To determine the prevalence of abnormal sinus roentgenograms in patients experiencing flare-ups of these conditions.
• To assess the correlation between clinical history and radiographic findings of sinusitis.

Main Methods:

• Retrospective analysis of patient data including clinical history and sinus roentgenograms.
• Comparison of the prevalence of abnormal sinus roentgenograms in patients with asthma exacerbations versus those with rhinitis.
• Evaluation of the predictive value of clinical history in identifying radiographic abnormalities.

Main Results:

• Abnormal sinus roentgenograms were detected in 47% of patients with asthma flare-ups, a statistically significant difference compared to 29% in patients with rhinitis.
• Patient's clinical history was frequently unhelpful in predicting the presence of sinus abnormalities.
• Maxillary sinusitis was the most common radiographic finding.

Conclusions:

• Roentgenography of the paranasal sinuses is a valuable tool for diagnosing sinusitis in patients with asthma, rhinitis, and urticaria.
• The erect Waters' view is identified as the most useful single roentgenogram for detecting maxillary sinusitis.
• Clinical assessment alone is insufficient for identifying sinusitis in this patient population, highlighting the importance of imaging.
