Abstract		One of the factors influeneing the choice of a cochlear implant (CI) device is the physical properties of the electrode array and the possibility of a deep insertion into the cochlea, also reaching the apical part, thus permitting the full use of all electrodes for stimulation (1). Good postoperative fitting of the speech processor in children requires objective data according to which we can orient ourselves in order not to exceed maximum comfort levels (MCLs) Š2, 3j. To achieve this, we concentrated on the intraoperative recordings of the musculus stapedius reflex (4). We present a series of 7 patients; 1 adult and 6 children, who had patent cochleae, and where deep insertion (up to 30 mm) was easily possible in all cases. Intraoperative stapedius reflex (STP) measurements were done using a standard procedure, and recorded. Current unit values for the STP are compared with MCL values recorded at the first fitting sessions. We conclude that STP is a useful tool for guidance in fitting speech processors in very young children.
