Event Description
|
A clinic reported that a patient experienced a burn during their thermage procedure.The nurse reported that frost was observed on the patient¿s lower left face just after the area was treated.A burn mark was also visible in the same area of the face.The available image was reviewed and two red lines are visible on the left cheek.The patient was treated with an unknown healing serum and intense pulsed light therapy.The patient''s current status was reported as the redness has subsided and residual hypopigmentation in the burn area is still visible.The treatment was performed at a maximum power level of 3.5.The treatment tip was inspected prior to use and no abnormalities were noted.Following the observation of frost on the patient the treatment tip was swapped out, but the system would not allow additional shots to be administered so the treatment was not completed.

Manufacturer Narrative

Corrected section d7a.A review of the manufacturing records show all requirements were met.The treatment tip and data-card logs were returned for evaluation.Evaluation of the treatment tip found no issues related to this event.Evaluation of the data-card found no issues with the system and handpiece, they performed as expected.Data-card logs do however show a large number of user errors, where constant force or full contact with skin was not maintained during the treatment.Failure to maintain constant force until the tone ends, indicating the end of the post cooling state, can result in an unsafe condition.If full perpendicular contact is not made during treatment, cryogen can pool to one side of the tip creating frosting on the tip surface, as was reported in this case.It was also reported this tip was used on a prior treatment.Thermage treatment tips are single use only, as re-use can lead to unsafe risks to patients.Based on the available information user technique and off-label use of the treatment tip resulted in unsafe treating conditions, most likely causing this event.
