(1) Background: Several types of hearing aids are available for the rehabilitation of vestibular-schwannoma (VS)-related hearing loss. There is a lack of recently published papers regarding this theme. The aim of the present work is to organize current knowledge. (2) Methods: A review of the literature regarding the topics “vestibular schwannoma”, “hearing loss”, and “hearing aid” was performed. Nineteen studies were thus considered. (3) Results: Conventional hearing aids, contralateral routing of signal (CROS) aids, bone anchored hearing aids (BAHA), and others are available options for hearing rehabilitation in VS patients. The speech discrimination score (SDS) is considered the best measure to assess candidacy for rehabilitation with hearing aids. The best hearing rehabilitative conditions in VS patients when using conventional hearing aid devices are a mild−moderate hearing loss degree with good word recognition (more than 50% SDS). CROS-Aid and BAHA are reported to be beneficial. CROS-Aid expands on the area of receiving hearing. BAHA aids use direct bone-conduction stimulation. Unfortunately, there are no available studies focused specifically on VS patients that compare CROS and BAHA technologies. (4) Conclusions: Hearing aids, CROS, and BAHA are viable options for rehabilitating hearing impairment in VS, but require an accurate case-by-case audiological evaluation for rehabilitating hearing impairment in VS. Further studies are needed to prove if what is currently known about similar hearing illnesses can be confirmed, particularly in the case of VS.

“…Neurofibromatosis type II (NF2) is an autosomal dominant inherited disease caused by mutations in the NF2 gene. It is clinically characterized by bilateral acoustic neuromas [vestibular schwannomas (VSs)] and is often associated with multiple nervous system tumors such as meningiomas, myelomas, astrocytomas, and paraspinal posterior root schwannomas [1]. The population incidence of NF2 is approximately 1:33 000, with an average onset age range of 18-24 years [2].…”

Treatment of neurofibromatosis type II with anlotinib: a case report and literature review

Patients with neurofibromatosis type II (NF2) usually require surgical treatment, but the probability of tumor recurrence remains high after surgical resection. Moreover, because most of NF2 lesions involve the facial nerve, the risk of facial nerve injury during the surgery is high. Stereotactic radiotherapy can be used to treat some cases of NF2. However, it is not recommended for treatment of multiple or large tumors, and surgical resection may be more difficult after radiotherapy. Few systemic treatments are available. At present, bevacizumab is considered the first-line drug treatment for fast-growing NF2. However, bevacizumab requires long-term administration, and tumor growth will resume after drug withdrawal. Here, we present a case of NF2 that developed exacerbations after multiple treatments with gamma knife and surgery, and achieved good results after later treatment with anlotinib. Accordingly, we propose that anlotinib may be a valuable treatment option for NF2.

Skull base tumors and, in particular, vestibular schwannoma (VS) are among the etiological reasons for single-sided deafness (SSD). Patients with SSD have problems in understanding speech in a noisy environment and cannot localize the direction of sounds. Baha is one of the most frequently used systems for SSD compensation. Out of 38 patients with SSD after retrosigmoid removal of VS who underwent testing with Baha softband, 16 were satisfied and were indicated for Baha implantation. Two surgical approaches have been used-the Nijmegen linear incision technique with subdermal thinning (Group I, implant BI300) and fast surgery technique without subdermal thinning (Group II, implant BIA400). The duration of the surgery, the implant stability measured by Ostell, and skin or soft tissue reactions in long range follow-up were evaluated and compared between Group I and II. There was a difference in duration of surgery, in Group II procedures averaged significantly faster (p > 0.001). In both groups, there was a similar trend of the gradual increase of implant stability. In the Group I and II, there was comparable rate of the skin or soft tissue reactions grade 0, I, II, or III. We have proved Baha to be a suitable possibility for SSD patients after the removal of VS, regardless of the approach. After the retrosigmoid approach to the VS, the key step of Baha implantation must be to reach intact healthy bone to avoid implantation into scar tissue.
