    The maxillary antral lining shares similarities with nasal mucosa but shows reduced gland activity and cilia. This makes the sinus lining more vulnerable to infection, necessitating prompt antibiotic treatment.

    Area of Science:

    • Otorhinolaryngology
    • Cell Biology
    • Microbiology

    Background:

    • The maxillary antral mucosa's structure is crucial for sinus health.
    • Understanding its cellular features aids in diagnosing and treating sinusitis.

    Purpose of the Study:

    • To investigate the fine structure of the maxillary antral mucosa.
    • To identify ultrastructural differences compared to nasal mucosa.
    • To correlate structural findings with susceptibility to infection.

    Main Methods:

    • Microscopic examination of maxillary antral mucosa tissue samples.
    • Comparative analysis with nasal mucosa.

    Main Results:

    • Maxillary antral mucosa resembles nasal mucosa in general structure.

  • Observed differences include reduced seromucinous gland activity, decreased tissue fluid-blood exchange, fewer cilia, and a more delicate, loosened epithelium.
  • These changes indicate diminished mucosal defense mechanisms.

    • Conclusions:

    • The maxillary sinus lining exhibits reduced resistance to infection due to structural changes.
    • Microorganisms can more easily penetrate the compromised mucosa.
    • Early systemic antibiotic administration, followed by postural drainage and irrigation, is recommended for treatment.
