Vagal Nerve Monitoring during Parapharyngeal Space Tumor Removal

Solitary fibrous tumor of the parapharyngeal space.

Solitary fibrous tumors are rare tumors originating from the mesenchymal tissue. In most cases they arise from the subpleural tissue but have also been described in other locations in the body. Most such tumors in the head and neck region occur in the orbit. Although malignant tumors can occur, benign tumors are far more common. The therapy is surgical excision.

A high-resolution CT scan of the temporal bone revealed bony erosion and widening of both the foramen ovale and the bony portion of the eustachian tube. A temporal bone MR image showed an intensely enha...
