Chronic maxillary atelectasis, a rare condition, affects 0.92% of patients. This study found it was bilateral in 22.2% of cases, suggesting a potentially higher prevalence than previously reported.
Area of Science:
- Otolaryngology
- Radiology
- Medical Imaging
Background:
- Chronic maxillary atelectasis is an uncommon condition with limited prevalence data.
- Understanding its occurrence and characteristics is crucial for diagnosis and management.
Purpose of the Study:
- To investigate the prevalence of chronic maxillary atelectasis.
- To determine the rate of bilateral involvement in chronic maxillary atelectasis.
Main Methods:
- Retrospective analysis of 5835 paranasal sinus computed tomography (CT) scans from 2016 to 2020.
- Diagnosis of chronic maxillary atelectasis based on CT findings.
Main Results:
- A prevalence of 0.92% was identified, with 54 patients diagnosed.
- Chronic maxillary atelectasis was unilateral in 77.8% and bilateral in 22.2% of affected patients.
- Eight patients presented with enophthalmos and facial asymmetry.
Conclusions:
- The prevalence of bilateral chronic maxillary atelectasis may be underestimated in existing literature.
- A unified classification is proposed, defining silent sinus syndrome as chronic maxillary atelectasis IIIS.

Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
