A user facility reported that a patient received a thermage treatment on the left eye and the patient smelled something burning.The system showed an error message and the doctor changed the return pad and continued the treatment.The error occurred more than 10 times, to which the patient then refused treatment.The patient cleaned her eyelids and found damage on her lower eyelids.The doctor inspected the tip and found there was a hole on the surface of the thermage treatment tip.The patient was given mupirocin ointment and growth factor to use daily.Available pictures were reviewed.Scabs are visible around one eye in the first picture.In two other pictures, the scabs are recovered with some visible post inflammation hyperpigmented area.It is noted that topical anesthetics were used for this procedure.The patient's current status is noted as an atrophic scar.It is uncertain if there will be permanent damage or scarring.No other treatments (besides thermage) were being performed in same area where the symptoms were reported.The patient hasn't undergone any other treatments in the same symptom area within the past 30 days.It is reported that the incident occurred at about 285 reps into the procedure.The highest energy level used was 5.0.Solta medical croygen and coupling fluid were used during this treatment.The treatment tip surface was inspected prior to use.Nothing was noted out of the ordinary and this is the first time the tip was used.The tip wasn't inspected during use and it was the first time it was used.

During evaluation of the tip, service confirmed dielectric membrane breakdown on the tip.Breakdown of the dielectric material can cause the radiofrequency energy, delivered by the system, to focus in a small area of the membrane, rather than to be uniformly distributed over the entire membrane area.Defects on the tip membrane can lead to a raise in temperature of the tip during treatment and can potentially cause patient burns.All the tips are visually inspected during the manufacturing and packaging process for any signs of damage to the tip membrane.According to thermage cpt system technical user¿s manual, burns are a known potential reaction to treatment.The procedure may produce heating in the upper layers of the skin, causing burns and subsequent blister and scab formation.There is a small chance of scar formation.Application of topical steroidal or antibiotic preparations may be of benefit.In the rare instance of a burn that results in a scar, the scar will probably be very small and respond readily to removal with a laser device.Datacard logs revealed errors occurred during treatment.Errors indicate a recoverable problem that requires operator intervention.If the error occurs during a radiofrequency treatment, the radiofrequency delivery will be stopped, then a post-cooling step will be completed prior to generating an ¿error tone¿ and displaying the event code and event message.After the error tone, the system will transition into action required mode and will display text with instructions for the operator indicating what action may be required to resolve the issue.Based on the evaluation of data, the system and handpiece performed as expected.A review of the manufacturing records showed all requirements were met.The lot history, trend analysis, risk analysis and/or directions for use review were considered acceptable, with the product performing within anticipated rates.Final test verification specifications are acceptable.No non-conformities or anomalies found related to this complaint when reviewing the device history record.Based on the available information, damage to the tip caused this event.No corrective action is required.
