Surgery of the ear and the lateral skull base: pitfalls and complications

“…Therefore, the surgeon should pursue maintenance of auditory function for smaller tumours only [ 273 ]. Good/serviceable hearing (class I/II hearing according to the Gardner-Robertson Hearing Scale) following microsurgical management of VS was reported in 50% of cases for the MF approach and in 31–33% for the RS approach [ 313 ], [ 314 ]. Furthermore, 37–73% of patients had postoperative hearing levels class A and B (according to the AAO-HNS hearing classification) following VS resection via the MF approach [ 276 ], [ 315 ], [ 316 ], [ 317 ], [ 318 ], [ 319 ], [ 320 ], [ 321 ], [ 322 ], [ 323 ].…”

“…Independent of the surgical approach chosen, facial nerve continuity is maintained after VS surgery in >95% of cases. Accordingly, normal postoperative function/mild dysfunction of the facial nerve (H-B grade I/II) has been described in 61–90% of patients [ 313 ], [ 314 ]. For small vestibular schwannomas, postoperative functional integrity of the facial nerve has even been reported in up to 97% of cases [ 320 ].…”
