Brief Summary

Researchers will compare oral flurbiprofen (%0.25) spray and ice cream to a placebo (a look-alike substance that contains no drug) to see if oral flurbiprofen (%0.25) spray and ice cream works to effect post-thyroidectomy throat pain and voice quality. Participants will:

  • Receive 1 puff of oral flurbiprofen (0.25%) spray or 105 ml of ice cream or 1 puff of oral spray prepared with drinking water (placebo) at 5 hours postoperatively according to randomization result
  • Undergo voice analysis using Praat voice analysis (University of Amsterdam) at 6 hours postoperatively
  • Undergo a visual analog scale for analgesia status at 6 hours postoperatively

Outcome Measures

Primary Outcomes (2)

  • Feasibility of flurbiprofen (0.25%) spray and ice cream on voice quality

    From enrollment to the postoperative sixth hour.

  • Feasibility of flurbiprofen (0.25%) spray and ice cream on pain palliation

    To compare the effects of flurbiprofen (0.25%) spray and ice cream on pain palliation in patients who underwent thyroidectomy, compared to a placebo group and each other.

    From enrollment to the postoperative sixth hour.
