AbstractBone conduction implants transfer sound to the inner ear through direct vibration of the skull. In patients with skull base tumors and infections, these devices can bypass a dysfunctional ear canal and/or middle ear. Though not all skull base surgery patients opt for bone conduction hearing rehabilitation, a variety of these devices have been developed and marketed over time. This article reviews the evolution and existing state of bone conduction technology.

Introduction:Hemifacial spasm (HFS) may be due to peripheral axon ephapsis or central motor neuron hyperexcitability. Low facial motor evoked potential (MEP) thresholds or MEP responses to single pulse stimulation (normally multipulse stimulation is needed) may support the central hypothesis.Methods:We retrospectively compared response thresholds for facial MEPs in 65 patients undergoing surgical microvascular decompression (MVD) for HFS and 29 patients undergoing surgery for skull base tumors.Results:Single pulse stimulation elicited facial Mep in up to 87% of HFS patients whereas only 10% of tumor patients responded to single pulse stimulation. When comparing facial MEP thresholds using multi-pulse stimulus trains the voltage required in the HFS group were significantly lower then in skull base tumor patients (p < 0.001). the MEP latencies and amplitudes at threshold stimulation were similar between the two groups.Conclusions:these results suggest the facial corticobulbar pathway demonstrates enhanced excitability in HFS.

ABSTRACTTotal removal is difficult to be performed in skull base tumors because its location is surrounded by important structures such as nerves and blood vessels. Therefore, radiotherapy is one of treatment modalities that has been proven efficacy. Simultaneous with the development of imaging technology and advancement of radiobiology, radiosurgery is an emerging therapeutic modality. Radiosurgery is radiotherapy method which delivers high doseirradiation in single fraction. Rational use of stereotactic radiosurgery on benign skull base tumor is from radiobiology point of view; there is no advantage can be achieved from conventional dose fractionated radiotherapy compared with high dose. However, if we want to delivered high dose radiation, we must apply rigid immobilization, target definition using stereotactic navigation and image guidance verification. Radiosurgery can only be delivered in small intracranial lesion.ABSTRAKReseksi total kadang sulit dilakukan pada tumor yang terletak pada dasar tengkorak. Hal ini disebabkan lokasinya dikelilingi oleh struktur saraf dan pembuluh darah penting. Oleh karena itu, radioterapi merupakan salah satu modalitas terapi yang sudah terbukti maanfaatnya. Sejalan dengan perkembangan teknologi pencitraan dan kemajuan pengetahuan radiobiologi, radiosurgery merupakan modalitas terapi yang melejit penggunannya. Radiosurgery adalah metode pemberian radioterapi dengan dosis tinggi dan diberikan dalam fraksi tunggal. Rasional penggunaan stereotactic radiosurgery pada tumor jinak dasar tengkorak adalah karena dari sudut pandang radiobiologi, tidak ada kelebihan dariradioterapi dengan dosis konvensional dibandingkan dengan dosis tinggi. Namun, untuk pemberian dosis tinggi diwajibkan imobilisasi yang rigid dan lokalisasi yang akurat dengan menggunakan navigasi stereotaktik dan verifikasi dengan panduan pencitraan radiologi. Radiosurgery hanya dapat diberikan pada kelainan intrakranial yang berukuran kecil.
