The treatment tip was returned for evaluation.During evaluation, the tip passed flow and thermistor testing.Visual inspection found damage to the tip membrane (dielectric breakdown).Evaluation of the datacard found multiple system errors had occurred during treatment.The device history record was reviewed and there were no discrepancies or unusual findings that relate to the reported issue.Breakdown of the treatment tip membrane 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.The thermage user manual and the technical bulletin instruct the operator to inspect the treatment tips for any signs of physical damage prior, during and after treatment.With respect to all thermage systems, clinicians should frequently inspect the tip membrane during treatment for signs of breakdown and build-up of foreign substances.With respect to the cpt system, solta recommends that a tip membrane inspection be performed at the outset of the procedure and every 50 (fifty) pulses thereafter.Solta also reiterates the importance of clinician attention to treatment error messages provided by the system, in particular messages indicating underforce and lifting irregularities.
