Summary
Chronic ear, nose, and throat (ENT) infections do not alter paranasal sinus development types. However, these infections can reduce the maximal anteroposterior diameter of the sinuses.
Area of Science:
- Anatomy
- Otolaryngology
- Radiology
Background:
- The development and pneumatization of paranasal sinuses have been explained by several hypotheses.
- Two main theories propose pneumatization as either a mechanical event from muscular traction or an active process involving respiratory mucosa osteoclastic potential.
Purpose of the Study:
- To investigate the impact of chronic ear, nose, and throat (ENT) infections on paranasal sinus development and pneumatization.
- To compare sinus development in patients with chronic ENT infections versus healthy subjects.
Main Methods:
- Analysis of 200 radiograms.
- Inclusion of subjects with chronic ENT infections and control subjects without prior medical history.
Main Results:
- Chronic ENT infections did not significantly alter the percentage distribution of paranasal sinus pneumatization types.
- A reduction in the anteroposterior maximal diameter of the paranasal sinuses was observed in patients with chronic infections.
Conclusions:
- The underlying mechanisms of paranasal sinus pneumatization appear unaffected by chronic ENT infections.
- Chronic infections are associated with reduced sinus size, specifically impacting the anteroposterior dimension.
