[Augmentation of the temporal fossa with Ionos bone cement]

To compensate for the loss of tissue after transferring the temporalis muscle, it is advisable to fill the temporalis fossa for aesthetic reasons. In so doing, we have used IONOS bone cement to augment the fossa after muscle transfers. Twelve procedures have been performed within the past 3 years. The average follow-up time has been 23 months. Surgery was required in 6 cases following delayed reconstruction to rehabilitate the paralyzed face after loss of facial nerve function, four times to stabilize a duraplasty at the skull base and twice for aesthetic facial augmentation. A prefabricated IONOS implant (IONOROC implant) was attached to the squama temporalis with fresh bone cement. In all cases a good aesthetic result was achieved. A temporary seroma occurred in 6 patients (50% of the cases) but resolved in 1-2 weeks without requiring further care. However, we now recommend that suction drainage be inserted for approximately 1 week after surgery. In two cases the IONOS implant had to be removed because of an infection.
