The ENT university clinic Frankfurt provides first activation of the sound processor of CI patients 2 – 3 days following surgery. Therefore, the postoperative wound swelling needs to subside to ensure a sufficient linking of processor coil and implant. Otherwise, patients are first fitted after a standard healing phase of 4 – 5 weeks. It can be assumend that the wearing comfort of the processor on the fresh wound is restricted by the bandage and potential postoperative pain, so that the processor is less accepted than after the standard healing phase. To evaluate the acceptance of the processor at early fitting, the daily processor usage is captured via objective data collection (datalogging). The usage data of early fitted CI patients (EF, n = 20) is compared to a control group (CG, n = 20) that was fitted after 4 – 5 weeks. The usage data was captuered after finishing all first fitting appointments (3 visits within 2 weeks) and at the control vistit after 3 months. After first activation, the results show a significant lower daily processor usage of the EF (9h/d) compared to the CG (12h/d). Whereas, at the 3-month visit, no significant difference in daily processor usage between the EF (13h/d) and the CG (12.5h/d) was found. At early fitting, wearing the processor seems to be more uncomfortable to the patients than during first activation after 4 – 5 weeks. Nevertheless, the data shows that early fitting is accepted by the patients and that the processor can be worn daily for a sufficient amount of time (9h/d).
