Abstrakt: | Objectives: Patient and parental pressure has led to the development of minimally invasive techniques for cochlear implantation. New devices such as the Clarion Hi Res 90K require modified surgical approaches. The procedure should ensure an incision less than 5 cm, fixation of the device to the skull, and positioning of the receiver coil such that the auditory stimulator can be worn comfortably behind the ear. The surgery should have a low morbidity.Methods: Eighteen patients undergoing implantation with the Clarion Hi Res 90K device were managed with the designed technique. The skin incision was centered behind the external auditory meatus. The mastoidectomy fashioned to ensure a safe posterior tympanotomy and cochleostomy. The well for the stimulator was placed posterior to the edge of the mastoidectomy at a distance the length of strengthened connector link to the electrode array and fixed passively by a groove and canl to the skull.Results: In all cases, the technique was able to be used. Operative time was reduced as compared with standard skin flaps. Postoperative pain was minimal and no surgical complication occurred. To date no movement of the devices have been noted.Conclusions: This minimally invasive technique is a safe convenient method for implanting this device. Early hospital discharge is achieved and no postoperative care is needed prior to “switch on.” [Copyright &y& Elsevier] |
