Summary
Scanning electron microscopy revealed significant changes in the mucociliary system of patients with endonasal polyposis. These alterations suggest a decreased function, potentially increasing susceptibility to infections.
Area of Science:
- Otolaryngology
- Cell Biology
- Microscopy
Context:
- Endonasal polyposis affects the nasal and sinus mucosa.
- The mucociliary system is crucial for airway clearance.
- Previous studies have not fully detailed the ultrastructural changes in polyposis.
Purpose:
- To investigate the ultrastructural morphology of the epithelium in endonasal polyposis using scanning electron microscopy.
- To evaluate the condition of cilia and goblet cells in affected tissues.
Summary:
- Scanning electron microscopy of 23 endonasal polyposis specimens showed a predominance of kinocilia-free epithelium.
- The epithelium exhibited dome-shaped bulging, loosening, and transitional forms from cylindrical to squamous.
- Goblet cells were altered, and ciliary structures displayed abnormalities, including loss of coordinated function and damage.
Impact:
- Findings suggest a significant decrease in mucociliary system function in endonasal polyposis.
- This impaired function may predispose patients to bacterial and viral infections.
- The study provides morphological evidence linking polyposis to compromised airway defense mechanisms.
