Summary
Conservative management best preserves hearing in stable neurofibromatosis type 2 tumors. For growing tumors, bevacizumab may offer short-term hearing benefits, while cochlear implants are superior for profound hearing loss.
Area of Science:
- Otolaryngology
- Neurosurgery
- Genetics
Background:
- Neurofibromatosis type 2 (NF2) commonly causes bilateral profound hearing loss, significantly impacting patient quality of life.
- Vestibular schwannomas are a hallmark of NF2, often leading to progressive hearing impairment.
Purpose of the Study:
- To systematically review current literature on hearing outcomes for various treatments of vestibular schwannomas in NF2 patients.
- To identify the most effective strategies for hearing preservation and rehabilitation in this population.
Main Methods:
- PubMed search using MeSH terms: 'Neurofibromatosis 2', 'Neuroma, Acoustic', and 'Hearing Loss'.
- Inclusion of studies with adequate hearing outcome data, excluding case studies unless for cochlear implant research.
- Quality assessment using the GRADE system; formal statistical analysis was not performed due to data heterogeneity.
Main Results:
- Conservative management is optimal for hearing preservation in stable tumors.
- Bevacizumab shows short-term promise for hearing preservation in growing tumors, potentially outperforming surgery and radiotherapy.
- Cochlear implantation yields superior auditory outcomes compared to auditory brainstem implantation for profound hearing loss, especially in untreated tumors.
Conclusions:
- Current literature on hearing preservation/rehabilitation in NF2 offers indicative but low-quality data, requiring cautious interpretation.
- Management of NF2-related vestibular schwannomas is complex, involving factors beyond hearing preservation.
- Further high-quality research is needed to guide optimal treatment decisions for hearing in NF2 patients.
