Normal Paranasal Sinuses Microflora Study

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Clinical Trial Summary

The purpose of this study is to check if bacterial and fungal flora exists in healthy paranasal sinuses, and whether it is identical to the flora of nasal cavity.

We plan to harvest tiny examples of maxillary sinus and nasal mucosa for tissue cultures during the orthognathic procedures involving maxillary remodeling.
