Couldwell, William T. | Transtemporal approach to the removal of a lateral pontine tumor | This video demonstrates a very useful trajectory to a pontine lesion. A 68-year-old man presented with tongue numbness and weakness. The approach used was a transtemporal presigmoid retrolabyrinthine approach to enable an orthogonal trajectory to the lateral pons. Following the transtemporal opening... | | 2014-01-01 |
