and cervical regions.

Patients are studied in 2 groups in each region.

- Group I-local anesthetic only.

- Group II-local anesthetic with 6 mg of non-particulate Celestone.

All patients will be unblinded at 12 or 24 months. Non-responsive patients will be unblinded
after 3 months and will be crossed over to a different group, if patient consents.
Non-responsive patients may be unblinded and withdrawn from the study at any time.
