Primary Outcome Measures:
  • Pain Score Using a 10-cm Visual Analog Pain Scale (1 = no Pain, 10 = Very Severe Pain) [ Time Frame: Immediately after injection (Time 0) ]
    Assessment of difference in pain score in the Radiesse Dermal Filler Mixed with Lidocaine nasolabial fold v. the Radiesse Dermal Filler without Lidocaine nasolabial fold using a 10-cm visual analog pain scale (1 = no pain, 10 = very severe pain).

  • Patients With Clinically Significant Reduction in Pain [ Time Frame: Immediately after injection (Time 0) ]
    Assessment of clinical significance of pain reduction in the Radiesse Injectable Dermal Filler Mixed with Lidocaine nasolabial fold v. Radiesse Injectable Dermal Filler without Lidocaine nasolabial fold defined as number of participants with >/= 2cm difference on a visual analog pain scale (1 = no pain, 10 = very severe pain).


Enrollment: 50
Study Start Date: September 2008
Study Completion Date: January 2009
Primary Completion Date: December 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Radiesse® Mixed with Lidocaine
Injectable Dermal Filler. The same 50 participants received both the treatment device and the control device at the same time (left and right sides of face).
Device: Radiesse® Injectable Dermal Filler Mixed with Lidocaine
Calcium hydroxylapatite particles suspended in an aqueous based gel carrier mixed with 2% lidocaine hydrochloride (HCl)
Active Comparator: Radiesse® without Lidocaine
Injectable Dermal Filler. The same 50 participants received both the treatment device and the control device at the same time (left and right sides of face.
Device: Radiesse® Injectable Dermal Filler without Lidocaine
Calcium hydroxylapatite particles suspended in an aqueous based gel carrier without 2% lidocaine hydrochloride (HCl)

Detailed Description:
To assess pain immediately after nasolabial fold treatment with Radiesse® Injectable Dermal Filler mixed with lidocaine in one nasolabial fold compared to Radiesse® Injectable Dermal Filler without lidocaine in the contralateral nasolabial fold.
