Figures & data
Table 1. Demographic and clinical data of the patients.
Table 2. Cochlear implant profile.
Figure 1. (A) HRCT showing bilateral cochlear otospongiosis and so-called halo effect (arrows). (B) 3 D reconstruction of MRI images shows complete obliteration of the basal turn of the scala tympani, but patent lumen of the scala vestibuli. That finding was confirmed intraoperatively.
Figure 2. PTAs of the Patient 2 with intracochlear schwannoma in the left and vestibular schwannoma at the level of right CPA. (A) PTA before radiotherapy, (B) PTA 8 months after radiotherapy, showing quick deterioration of the hearing and development of almost complete deafness.
Figure 3. (A) Preoperative MRI T1 sequence with gadolinium enhancement showing tumor at the right CPA, but also contrasting small lesions along basal turn of the left cochlea and vestibule. (B) Postoperative CT scan showing electrode array in the left cochlea after subtotal petrosectomy and large craniotomy for translabyrinthine approach removal of tumor from the right.
