Trial design

CTIS Part I — objectives, methods, condition coding

Main objective

Scope: Therapy

To evaluate the clinical tolerance (safety, adverse effects) of an injection of a mixture of bupivacaine (100 mg) and dexamethasone (2 mg) into parotid tissue up to 15 days after partial parotidectomy for a benign tumor.

Secondary objectives 4

  1. To assess postoperative pain using a standardized scale (VAS) during the 15-day follow-up period.
  2. To evaluate the prevalence of salivary fistulas or sialoceles.
  3. To assess wound-healing quality at 15 days of follow-up.
  4. To evaluate the feasibility of injecting bupivacaine/dexamethasone into parotid tissue after parotidectomy.
