OBJECTIVE: To investigate mucosal pathologic and ultrastructure changes relate to experimental maxillary sinusitis process in rabbits. The demarcation of acute and chronic maxillary sinusitis will be determined according to pathologic effects.
METHOD: Thirty New Zealand white rabbits have been induced sinusitis will be divided into different groups according to the time of process. The pathologic changes are observed by microscope, scanning electric microscope and transmission electric microscope.
RESULT: Within 3 weeks to induce infection the inflammation mainly show in acute style while after 3 weeks the main manifestation are chronic changes. In epithelium layer cilia shedding increased, the number of goblet cell added, squamous epithelium metaplasia and epithelia necrosis were observed during inflammatory process. In lamina propria glands metaplasia and decreased, the fibrosis is densed.
CONCLUSION: The pathologic changes of maxillary mucosa are related to process. The borderline of acute and chronic experimental maxillary sinusitis is 3 weeks.
