Temporal Bone Subtotal Resection -Already written


Subtotal temporal bone resection (STBR) is performed on tumors that involve the mastoid, middle ear, inner ear, or lateral skull base. In STBR the medial margin may be obtained in a piecemeal fashion, usually with a drill. The specimen includes the lateral temporal bone dissection (LTBR) along with additional dissection of the otic capsule and the medial bony wall of the middle ear and mastoid.
